The feasibility of thermoluminescence (TL) to differentiate irradiated Chinese medicinal herbs from non-irradiated was investigated. Thirty different dried Chinese herbs were tested, including root, flower, ramulus, rhizome, cortex, and whole plant samples. Irradiation of Chinese herbs was associated with strong TL peaks at ∼150-250 deg C, while TL curves of non-irradiated herbs had very low intensities above 250 deg C, which was also confirmed by the TL ratio (non-irradiated, TL 1 /TL 2 1 /TL 2 > 0.1) except for sterculia lychnophora, semen cassia, flos inulae, and anemone root. TL ratios of some herbs indicated irradiation (TL 1 /TL 2 > 0.1) even if the irradiated components were as low as 0.1 %. Thus we demonstrated that TL analysis had excellent sensitivity and reliability for the identification of irradiated Chinese herbs. (author)

Full Text Available Transcriptomics using DNA microarray has become a practical and popular tool for herbal medicine study because of high throughput, sensitivity, accuracy, specificity, and reproducibility. Therefore, this article focuses on the overview of DNA microarray technology and the application of DNA microarray in Chinese herbal medicine study. To understand the number and the objectives of articles utilizing DNA microarray for herbal medicine study, we surveyed 297 frequently used Chinese medicinal herbs listed in Pharmacopoeia Commission of People’s Republic of China. We classified these medicinal herbs into 109 families and then applied PudMed search using “microarray” and individual herbal family as keywords. Although thousands of papers applying DNA microarray in Chinese herbal studies have been published since 1998, most of the articles focus on the elucidation of mechanisms of certain biological effects of herbs. Construction of the bioactivity database containing large-scaled gene expression profiles of quality control herbs can be applied in the future to analyze the biological events induced by herbs, predict the therapeutic potential of herbs, evaluate the safety of herbs, and identify the drug candidate of herbs. Moreover, the linkage of systems biology tools, such as functional genomics, transcriptomics, proteomics, metabolomics, pharmacogenomics and toxicogenomics, will become a new translational platform between Western medicine and Chinese herbal medicine.

Some traditional Chinese medicinal seeds and fruits are well known for their antioxidant properties. This research aims to investigate whether Fructus Lycii, Fructus Schisandrae Chinensis, Fructus Ligustri Lucidi and Semen Cuscutae protect DNA from oxidant challenge by hydrogen peroxide (H(2)O(2)). The standard comet assay was used to assess the genoprotective effect of these medicinal herbs. Blood was taken from three healthy adults, aged from 36 to 42. Lymphocytes were isolated and treated with different concentrations of aqueous herbal extracts, while controls were treated with phosphate buffered saline. The lymphocytes were stressed with 50 μM H(2)O(2). Treated cells were embedded in agarose and layered on slides. These sandwiched lymphocytes were lysed and afterwards subjected to an electric field in an alkaline environment. Damaged DNA was pulled out from the nucleus towards the positive electrode as a comet tail; its density was related to the degree of DNA damage. Finally, the slides were stained with fluorescence dye and tails were visually scored for 100 cells. The experiment was repeated three times and DNA damage in treated cells was compared to the controls. There was no statistical difference in DNA damage among the herb treated cells and untreated cells in the comet assay. Our data demonstrated that the selected medicinal herbs did not show in vitro DNA protection in the comet assay against oxidant challenge.

To analyze the prescription and medication rules of Chinese medicines in the treatment of palpitations in the Chinese journal full text database(CNKI) by using traditional Chinese medicine inheritance system, and provide a reference for further research and development of modern traditional Chinese medicines(TCMs) in treatment of palpitations. In order to give better guidance for clinical mediation, prescriptions used for treatment of palpitations in CNKI were collected, and then were input to the TCM inheritance support system for establishing a Chinese medicine prescription database for palpitations. The software's revised mutual information, complex system entropy clustering and other data mining methods were adopted to analyze the prescriptions according to the frequencies of herbs, "four natures", "five flavors" and "meridians" of the high-frequency medicines in the database, identify the core herbs and application characteristics, and analyze the prescription rules and medication experience. Totally, 545 prescriptions used for palpitation were included in this study and involved 247 Chinese herbs. The analysis results showed that the herbs in prescriptions for palpitation mostly had the warm property, and the herbs in heart and spleen meridian accounted for a larger proportion, indicating that the treatment was mainly to nourish heart and strengthen spleen. The top 11 herbs in usage frequency were consistent with the high-frequency medicines in medication patterns of common herbal pairs; therefore, we considered that these 11 herbs were the core herbs; the core herbal combination included Cassia Twig, Licorice, fossil fragments, Ostreae decoction, and evolved into 9 new prescriptions for treating palpitation. Our results objectively presented the prescription and medication rules for treating palpitation and provided extremely effective guidance for the clinical therapy.

Chronic prostatitis is a common male disease, and its pathogenesis is not yet clear. Most scholars believe that oxidative stress and immune imbalance are the keys to the occurrence and progression of chronic prostatitis. Currently immunotherapy of chronic prostatitis remains in the exploratory stage. This article relates the active ingredients of 5 Chinese medicinal herbs (total glucosides of paeony, tripterigium wilfordii polglycosidium, curcumin, geniposide, and quercetin) for the treatment of chronic prostatitis and their possible action mechanisms as follows: 1) inhibiting the immune response and activation and proliferation of T-cells, and adjusting the proportion of Th1/Th2 cells; 2) upregulating the expression of Treg and enhancing the patient's tolerability; 3) suppressing the activation of the NF-kB factor, reducing the release of iNOS, and further decreasing the release of NO, IL-2 and other inflammatory cytokines, which contribute to the suppression of the immune response; 4) inhibiting the production of such chemokines as MCP-1 and MIP-1α in order to reduce their induction of inflammatory response. Studies on the immune mechanisms of Chinese medicinal herbs in the treatment of chronic prostatitis are clinically valuable for the development of new drugs for this disease.

The co-evolution of Orobanche spp. and their hosts within the same environment has resulted in a high degree of adaptation and effective parasitism whereby the host releases parasite germination stimulants, which are likely to be unstable in the soil. Our objective was to investigate whether extracts from non-host plants, specifically, Chinese medicinal plants, could stimulate germination of Orobanche spp. Samples of 606 Chinese medicinal herb species were extracted with deionized water and methanol. The extracts were used to induce germination of three Orobanche species; Orobanche minor, Orobanche cumana, and Orobanche aegyptiaca. O. minor exhibited a wide range of germination responses to the various herbal extracts. O. cumana and O. aegyptiaca exhibited an intermediate germination response to the herbal extracts. O. minor, which has a narrow host spectrum, showed higher germination rates in response to different herbal extracts compared with those of O. cumana and O. aegyptiaca, which have a broader host spectrum. Methanolic extracts of many Chinese herbal species effectively stimulated seed germination among the Orobanche spp., even though they were not the typical hosts. The effective herbs represent interesting examples of potential trap crops. Different countries can also screen extracts from indigenous herbaceous plants for their ability to induce germination of Orobanche spp. seeds. The use of such species as trap plants could diminish the global soil seed bank of Orobanche.

Full Text Available Inducible nitrogen oxide synthase (iNOS is the primary contributor of the overproduction of nitric oxide and its inhibitors have been actively sought as effective anti-inflammatory agents. In this study, we prepared 70% ethanol extracts from 81 Chinese herbs. These extracts were subsequently evaluated for their effect on nitrogen oxide (NO production and cell growth in LPS/IFNγ-costimulated and unstimulated murine macrophage RAW264.7 cells by Griess reaction and MTT assay. Extracts of Daphne genkwa Sieb.et Zucc, Caesalpinia sappan L., Iles pubescens Hook.et Arn, Forsythia suspensa (Thunb. Vahl, Zingiber officinale Rosc, Inula japonica Thunb., and Ligusticum chuanxiong Hort markedly inhibited NO production (inhibition > 90% at 100 μg/mL. Among active extracts (inhibition > 50% at 100 μg/mL, Rubia cordifolia L., Glycyrrhiza glabra L., Iles pubescens Hook.et Arn, Nigella glandulifera Freyn et Sint, Pueraria lobata (Willd. Ohwi, and Scutellaria barbata D. Don displayed no cytotoxicity to unstimulated RAW246.7 cells while increasing the growth of LPS/IFNγ-costimulated cells. By analyzing the correlation between their activities and their Traditional Chinese Medicine (TCM characteristics, herbs with pungent flavor displayed potent anti-inflammatory capability. Our study provides a series of potential anti-inflammatory herbs and suggests that herbs with pungent flavor are candidates of effective anti-inflammatory agents.

Because the deposition of beta-amyloid protein (Abeta) is a consistent pathological hallmark of Alzheimer's disease (AD) brains, inhibition of Abeta generation, prevention of Abeta fibril formation, or destabilization of preformed Abeta fibrils would be attractive therapeutic strategies for the treatment of AD. We examined the effects of several medicinal herbs used in traditional Chinese medical formulae on the formation and destabilization of Abeta fibrils by using the thioflavin T binding assay, atomic force microscopic imaging, and electrophoresis. Our study demonstrates that several of these herbs have potent inhibitory effects on fibril formation of both Abeta(1-40) and Abeta(1-42) in concentration-dependent manners; in particular, Uncaria rhynchophylla inhibited Abeta aggregation most intensively. Significant destabilization of preformed Abeta(1-40) and Abeta(1-42) fibrils was also induced by Uncaria rhynchophylla as well as some other herb extracts. Three-dimensional HPLC analysis indicated that the water extract of this herb contains several different chemical compounds, including oxindole and indol alkaloids, which have been regarded as neuroprotective. Our results suggest that Uncaria rhynchophylla has remarkably inhibitory effects on the regulation of Abeta fibrils, and we conclude that this medicinal herb could have the potency to be a novel therapeutic agent to prevent and/or cure AD.

Traditional Chinese Medicine and Herb-induced Liver Injury: Comparison with Drug-induced Liver Injury.

2018-03-28

Cases of suspected herb-induced liver injury (HILI) caused by herbal Traditional Chinese Medicines (TCMs) and of drug-induced liver injury (DILI) are commonly published in the scientific literature worldwide. As opposed to the multiplicity of botanical chemicals in herbal TCM products, which are often mixtures of several herbs, conventional Western drugs contain only a single synthetic chemical. It is therefore of interest to study how HILI by TCM and DILI compare with each other, and to what extent results from each liver injury type can be transferred to the other. China is among the few countries with a large population using synthetic Western drugs as well as herbal TCM. Therefore, China is well suited to studies of liver injury comparing drugs with TCM herbs. Despite some concordance, recent analyses of liver injury cases with verified causality, using the Roussel Uclaf Causality Assessment Method, revealed major differences in HILI caused by TCMs as compared to DILI with respect to the following features: HILI cases are less frequently observed as compared to DILI, have a smaller proportion of females and less unintentional rechallenge events, and present a higher rate of hepatocellular injury features. Since many results were obtained among Chinese residents who had access to and had used Western drugs and TCM herbs, such ethnic homogeneity supports the contention that the observed differences of HILI and DILI in the assessed population are well founded.

Chinese medicine is a historic cultural legacy of China. It has made a significant contribution to medicine and healthcare for generations. The development of Chinese herbal medicine analysis is emphasized by the Chinese pharmaceutical industry. This study has carried out the experimental analysis of ten kinds of Chinese herbal powder including Fritillaria powder, etc., based on the photoacoustic spectroscopy (PAS) method. First, a photoacoustic spectroscopy system was designed and constructed, especially a highly sensitive solid photoacoustic cell was established. Second, the experimental setup was verified through the characteristic emission spectrum of the light source, obtained by using carbon as a sample in the photoacoustic cell. Finally, as the photoacoustic spectroscopy analysis of Fritillaria, etc., was completed, the specificity of the Chinese herb medicine analysis was verified. This study shows that the PAS can provide a valid, highly sensitive analytical method for the specificity of Chinese herb medicine without preparing and damaging samples.

Parkinson's disease is a progressive neurodegenerative disorder. Although both genetic and environmental factors are implicated in the development of Parkinson's disease, the cause of the disease is still unclear. So far conventional treatments to Parkinson's are symptomatic relief and focused mainly on motor symptoms. Chinese herbal medicine has been used to treat many conditions in China, Korea, Japan, and many Southeast Asian countries for 1000 years. During past a few decades, Chinese herbal medicine has gained wider and increasing acceptance within both public and medical profession due to its effectiveness on many conditions in western countries. In this chapter, mechanisms of action of many Chinese herbal compounds/extracts and Chinese herb formulas on the models of Parkinson's were reviewed. Further, reports of effectiveness of Chinese herb formulas on patients with Parkinson's were summarized. It was shown that both Chinese herbal compounds/extracts and herb formulas have either specific target mechanisms of action or multitargets mechanisms of action, as antioxidant, antiinflammatory, and antiapoptosis agents. Clinical studies showed that Chinese herb formulas as an adjunct improved both motor and nonmotor symptoms, and reduced dose of dopaminergic drugs and occurrence of dyskinesia. The evidence from the studies suggests that Chinese herb medicine has potential, acting as neuroprotective to slow down the progression of Parkinson's, and it is able to simultaneously treat both motor and nonmotor symptoms of Parkinson's. More studies are needed to explore the new compounds/extracts derived from Chinese herbs, in particular, their mechanisms of action. It is hopeful that new drugs developed from Chinese herb compounds/extracts and Chinese herb formulas will lead to better and complimentary therapy to PD. © 2017 Elsevier Inc. All rights reserved.

"Microcosmic syndrome", "treatment based on syndrome differentiation", and "combination of disease identification and syndrome differentiation" generally refer to a mode: following the syndrome if with no disease identified, following the disease if with no syndrome type differentiated. For example, Chinese medical treatment of hypertension, high blood lipids, increased transaminase, and so on candirectly use Chinese recipes, but no longer with syndrome differentiation. Clinical application of Chinese patent medicine can also obtain favorable clinical. Western doctors need not follow syndrome differentiation. The invention of artemisinin was screened from more than 40 000 kinds of compounds and herbs, but with no reference of any traditional Chinese medical theory. A lot of folk remedy and empirical recipes have obtained effective efficacy but unnecessarily with profound Chinese medical theories. Various evidences showed that disease can also be cured without syndrome differentiation. I held that it might be associated with the same mechanism of Chinese medicine and Western medicine. Any disease can be cured or alleviated by Chinese medicine is a result from its modern pharmacological effect, which is achieved by improving etiologies, and pathogeneses. I was inspired by whether we can directly use traditional Chinese medicine with modern pharmacological effects to treat symptomatic disease. So I raised an idea of microcosmic Chinese medicine used by Western medicine, i.e., we find and use Chinese herbs with relatively effective modern pharmacological effect to treat diseases targeting at patients' clinical symptoms and signs, as well as various positive laboratory results (collectively called as microscopic dialectical indicators). More Western doctors would use it to treat disease due to omission of complicated and mysterious syndrome differentiation. This will promote extensive application and expansion of Chi- nese medicine and pharmacy, enlarge the team of

To observe the effect of certain active components from traditional Chinese medicinal herbs on Aβ secretion rates with L-[ 35 S]-Methionine, β-amyloid peptide (Aβ) in SK-N-SH cell lines stably transfected with APP695 was metabolically labeled with L-[ 35 S]-Methionine. the supernatant from culture medium was immunoprecipitated with monoclonal antibody against Aβ 22-35 , Western blot was carried out, and the gray density of Aβ band in the autoradiograph was measured by an image analysis system. The active components from certain traditional Chinese medicinal herbs (ZMS from Zhimu and AST and HT from Huangqi) were added to the culture medium at a final concentration of 10 -5 mol/L. An Aβ band in the autoradiograph was clearly viewed in the culture medium after 24 h incorporation of [ -35 S]-Methionine which represent the secretion rate of Aβ by the cells. One of the 3 tested components (AST) could significantly reduce the Aβ secretion rate while the other two showed no effect. The preliminary result showed that certain active component from traditional Chinese medicines could decrease the Aβ secretion rate but other active components could not. Combined use of the AST and ZMS was more effective than single AST. (authors)

Herbal medicines are widely used for treating liver diseases and generally regarded as safe due to their extensive use in Traditional Chinese Medicine practice for thousands of years. However, in recent years, there have been increased concerns regarding the long-term risk of Herb-Induced Liver Injury (HILI) in patients with liver dysfunction. Herein, two representative Chinese herbal medicines: one-Xiao-Chai-Hu-Tang (XCHT)-a composite formula, and the other- Radix Polygoni Multiflori (Heshouwu) -a single herb, were analyzed by network pharmacology study. Based on the network pharmacology framework, we exploited the potential HILI effects of XCHT and Heshouwu by predicting the molecular mechanisms of HILI and identified the potential hepatotoxic ingredients in XCHT and Heshouwu . According to our network results, kaempferol and thymol in XCHT and rhein in Heshouwu exhibit the largest number of liver injury target connections, whereby CASP3, PPARG and MCL1 may be potential liver injury targets for these herbal medicines. This network pharmacology assay might serve as a useful tool to explore the underlying molecular mechanism of HILI. Based on the theoretical predictions, further experimental verification should be performed to validate the accuracy of the predicted interactions between herbal ingredients and protein targets in the future.

The aim of the study was to evaluate the effects of two kinds of Chinese medicinal herbs, Isatis tinctoria L (ITL) and Daphne giraldii Nitsche (DGN), on a rat model of chronic Pseudomonas aeruginosa lung infection mimicking cystic fibrosis (CF). Compared to the control group, both drugs were able to reduce the incidence of lung abscess (p < 0.05) and to decrease the severity of the macroscopic pathology in lungs (p < 0.05). In the great majority of the rats, the herbs altered the inflammatory response in the lungs from an acute type inflammation, dominated by polymorphonuclear leukocytes (PMN), to a chronic type inflammation, dominated by mononuclear leukocytes (MN). DGN also improved the clearance of P. aeruginosa from the lungs (p < 0.03) compared with the control group. There were no significant differences between the control group and the two herbal groups with regard to serum IgG and IgA anti-P. aeruginosa sonicate antibodies. However, the IgM concentration in the ITL group was significantly lower than in the control group (p < 0.03). These results suggest that the two medicinal herbs might be helpful to CF patients with chronic P. aeruginosa lung infection, DGN being the most favorable.

High price and difficult to get of reference substance have become obstacles to HPLC assay of ethnic medicine. A new method based on quantitative reference herb (QRH) was proposed. Specific chromatograms in fruits of Capsicum frutescens were employed to determine peak positions, and HPLC quantitative reference herb was prepared from fruits of C. frutescens. The content of capsaicin and dihydrocapsaicin in the quantitative control herb was determined by HPLC. Eleven batches of fruits of C. frutescens were analyzed with quantitative reference herb and reference substance respectively. The results showed no difference. The present method is feasible for quality control of ethnic medicines and quantitative reference herb is suitable to replace reference substances in assay.

Full Text Available Chinese herb medicine (CHM is the most commonly reported traditional Chinese medicine (TCM modality. This study aimed to assess the prevalence and associated factors of CHM use in cancer patients in southwestern China. Cancer patients from eleven comprehensive cancer centers were asked to complete a structured questionnaire. Of 587 available replies, 53.0% used CHM. Multiple logistic regression analysis showed that educational level, stage of disease, duration of cancer since diagnosis, marital status, and previous use of CHM were strongly associated with CHM use after cancer diagnosis. The source of information about CHM was mainly from media and friends/family. CHM products were used without any consultation with a TCM practitioner by 67.5% of users. The majority used CHM to improve their physical and emotional well-beings and to reduce cancer therapy-induced toxicities. About 4.5% patients reported side effects of CHM. This survey revealed a high prevalence of CHM use among cancer patients. However, these patients did not get sufficient consultation about the indications and contradictions of these drugs. It is imperative for oncologists to communicate with their cancer patients about the usage of CHM so as to avoid the potential side effects.

Liquorice is the root of Glycyrrhiza uralensis Fisch. or Glycyrrhiza glabra L., Leguminosae. Licorice is described as 'National Venerable Master' in Chinese medicine and plays paradoxical roles, i.e. detoxification/strengthen efficacy and inducing/enhancing toxicity. Therefore, licorice was called "Two-Face" herb in this paper. The aim of this study is to discuss the paradoxical roles and the perspective usage of this "Two-Face" herb using data mining and frequency analysis. More than 96,000 prescriptions from Chinese Formulae Database were selected. The frequency and the prescription patterns were analyzed using Microsoft SQL Server 2000. Data mining methods (frequent itemsets) were used to analyze the regular patterns and compatibility laws of the constituent herbs in the selected prescriptions. The result showed that licorice (Radix glycyrrhizae) was the most frequently used herb in Chinese Formulae Database, other frequently used herbs including Radix Angelicae Sinensis (Dang gui), Radix et rhizoma ginseng (Ren shen), etc. Toxic herbs such as Radix aconiti lateralis praeparata (Fu zi), Rhizoma pinelliae (Ban xia) and Cinnabaris (Zhu sha) are top 3 herbs that most frequently used in combination with licorice. Radix et rhizoma ginseng (Ren shen), Poria (Fu ling), Radix Angelicae Sinensis (Dang gui) are top 3 nontoxic herbs that most frequently used in combination with licorice. Moreover, Licorice was seldom used with sargassum (Hai Zao), Herba Cirsii Japonici (Da Ji), Euphorbia kansui (Gan Sui) and Flos genkwa (Yuan Hua), which proved the description of contradictory effect of Radix glycyrrhizae and these herbs as recorded in Chinese medicine theory. This study showed the principle pattern of Chinese herbal drugs used in combination with licorice or not. The principle patterns and special compatibility laws reported here could be useful and instructive for scientific usage of licorice in clinic application. Further pharmacological and chemical researches are

Insomnia is a condition with sleep problems and many people suffered from it. Chronic insomnia can last for long time and it will severely affect people's health and the quality of life. In conventional medicine, the most commonly used the medicine is benzodiazepine. It is effective but also has significant side effects. Patients try to use some kinds of alternative medicines. Chinese medicinal herbs and formulas have been used in the treatment of insomnia for more than 2000 years in China. In recent decades, Chinese herbal medicine has been widely used in the Western countries. Many clinical studies including randomized controlled clinical trials and research on pharmacological action mechanisms of the herbs for treatment of insomnia have been conducted. It is very important and very helpful to review the published research papers to gather the available information for a critical analysis. This chapter evaluated the data from both of clinical studies and pharmacological researches on the therapeutic formulas and on some key herbs used in the treatment of insomnia. Clinical studies showed a very wide spectrum of herbs that were used in clinical treatment of insomnia. This was due to different syndrome patterns happened with insomnia. This brought complexity and difficulties to identify which are the essential key herbs or formulas. It was found Suanzaoren decoction (Ziziphus spinose decoction ) is the most frequently used formula for the treatment of insomnia. Based on the clinical data, several herbs were identified as most frequently used sedative and hypnotic herbs in Chinese herbal medicine including Suanzaoren (Ziziphus spinose ), Fuling (Poria cocos ), and Gancao (Glycyrrhiza uralensis ). The underlying pharmacological action mechanisms discovered in the studies on some key herbs used in the treatment of insomnia were evaluated. The major pharmacological action mechanisms shared by most of the sedative herbs are to act through the neurotransmitter gamma

Full Text Available The relationship between the antioxidant activities and inhibitory effect of 14 Chinese medicinal herbs against oxidized low-density lipoprotein (LDL formation was evaluated. Prolongation of the lag phase of LDL oxidation depended on the concentration of the herbs. The concentration of each herb that was able to prolong the lag time by about two-fold was calculated and expressed as doubling-time concentration. The lower the doubling-time concentration, the stronger the inhibitory effect exhibited toward LDL oxidation. Among them, Chrysanthemi Flos (Chrysanthemum morifolium ramat; 甘菊花 gān jú huā, Crataegi Fructus (Crataegus pinnatifida Bge. var. major N.E.Br.; 山楂 shān zhā, and Roselle (Hibiscus sabdariffa Linn.; 洛神 luò shén showed significant inhibitory effects. Correlation coefficients between doubling-time concentration and radical-scavenging activities were high; the total phenolic content was also high. In conclusion, phenolic compounds contributed not only to antioxidant activities, but also to the inhibitory effect against LDL oxidation. Chrysanthemi Flos, Crataegi Fructus, and H. sabdariffa, with lower doubling-time concentrations, could be potent phytochemical agents to reduce LDL oxidation and prevent the progression of atherosclerosis.

Our previous study demonstrated that an up-regulation of the Brain-Derived Neurotrophic Factor (BDNF) signaling pathway is involved the mechanism causing the recurrence of triple negative breast cancer. The aim of this study is to investigate the effects of commonly used Chinese medicinal herbs on MDA-MB-231 and HUVEC cells and how they interact with BDNF. Human TNBC MDA-MB-231 cells and human endothelial HUVEC cells were used to explore the effect of commonly used Chinese herbal medicines on cancer cells alone, on endothelial cells alone and on cancer cell/endothelial cell interactions; this was done via functional studies, including migration and invasion assays. Furthermore, Western blot analysis and real-time PCR investigations were also used to investigate migration signal transduction, invasion signal transduction, and angiogenic signal transduction in these systems. Finally, the effect of the Chinese medicinal herbs on cancer cell/endothelial cell interactions was assessed using co-culture and ELISA. In terms of autoregulation, BDNF up-regulated TrkB gene expression in both MDA-MB-231 and HUVEC cells. Furthermore, BDNF enhanced migration by MDA-MB-231 cells via Rac, Cdc42 and MMP, while also increasing the migration of HUVEC cells via MMP and COX-2 expression. As measured by ELISA, the Chinese herbal medicinal herbs A. membranaceus, P. lactiflora, L. chuanxiong, P. suffruticosa and L. lucidum increased BDNF secretion by MDA-MB-231 cells. Similarly, using a co-culture system with MDA-MB-231 cells, A. membranaceus and L. lucidum modulated BDNF-TrkB signaling by HUVEC cells. We conclude that BDNF plays an important role in the metastatic interaction between MDA-MB-231 and HUVEC cells. Some Chinese medicinal herbs are able to enhance the BDNF-related metastatic potential of the interaction between cancer cells and endothelial cells. These findings provide important information that should help with the development of integrated medical therapies for breast

Drug-drug interactions have long been an active research area in clinical medicine. In Taiwan, however, the widespread use of traditional Chinese medicines (TCM) presents additional complexity to the topic. Therefore, it is important to see the interaction between traditional Chinese and western medicine. (1) To create a comprehensive database of multi-herb/western drug interactions indexed according to the ways in which physicians actually practice and (2) to measure this database's impact on the detection of adverse effects between traditional Chinese medicine compounds and western medicines. First, a multi-herb/western medicine drug interactions database was created by separating each TCM compound into its constituent herbs. Each individual herb was then checked against an existing single-herb/western drug interactions database. The data source comes from the National Health Insurance research database, which spans the years 1998-2011. This study estimated the interaction prevalence rate and further separated the rates according to patient characteristics, distribution by county, and hospital accreditation levels. Finally, this new database was integrated into a computer order entry module of the electronic medical records system of a regional teaching hospital. The effects it had were measured for two months. The most commonly interacting Chinese herbs were Ephedrae Herba and Angelicae Sinensis Radix/Angelicae Dahuricae Radix. Ephedrae Herba contains active ingredients similar to in ephedrine. 15 kinds of traditional Chinese medicine compounds contain Ephedrae Herba. Angelicae Sinensis Radix and Angelicae Dahuricae Radix contain ingredients similar to coumarin, a blood thinner. 9 kinds of traditional Chinese medicine compounds contained Angelicae Sinensis Radix/Angelicae Dahuricae Radix. In the period from 1998 to 2011, the prevalence of herb-drug interactions related to Ephedrae Herba was 0.18%. The most commonly prescribed traditional Chinese compounds were

Recently, a new syndromic disease combination theory of traditional Chinese medicine (TCM) for hypertensive treatment has been introduced. In the wake of this new concept, a new science-based TCM formula that counteracts various syndromes is needed. The objective of this study was to develop such a formula. Five of the most clinically prescribed TCM herbs that work on different syndromes, namely Gastrodia elata, Uncaria rhynchophylla, Pueraria thomsonii, Panax notoginseng, and Alisma orientale, were selected for this study. The fingerprints of these five herbs were analyzed by tri-step Fourier transform infrared spectroscopy. Three different solvents, 95% ethanol, 50% ethanol, and distilled water, were used for the maceration of the herbs and their vasodilatory effects were studied using in vitro precontracted aortic ring model. Among these, the 50% ethanolic extracts of G. elata (GE50) and A. orientale (AO50), and 95% ethanolic extracts of U. rhynchophylla (UR95), P. thomsonii (PT95), and P. notoginseng (PN95) were found to be the most effective for eliciting vasodilation. Thus, these five extracts were used for orthogonal stimulus-response compatibility group studies by using L 25 (5 5 ) formula. The best combination ratio for GE50, UR95, PT95, PN95, and AO50, which was assigned as Formula 1 (F1), was found at EC 0 , EC 25 , EC 20 , EC 20 , and EC 10 , respectively. The vasodilatory effect of the extracts prepared from different extraction methods using F1 ratio was also studied. From the results, the EC 50 and R max of total 50% ethanolic extract of five herbs using F1 ratio (F1-2) were 0.028 ± 0.005 mg/mL and 101.71% ± 3.64%, with better values than F1 (0.104 ± 0.014 mg/mL and 97.80% ± 3.12%, respectively). In conclusion, the optimum ratio and appropriate extraction method (F1-2) for the new TCM formula were revealed.

Essential and toxic trace elements in the chinese medicine

The concentration of certain toxic and essential elements in various raw materials of Chinese herbs and 'scientific Chinese medicine' were determined by atomic absorption spectrometry (AAS) and instrumental neutron activation analysis (INAA). Correlation of these elements as they exist in the raw materials and in the prescription of medicine were investigated and the approximate intake of elements by patients were estimated. Values of elements determined both by AAS and INAA presented excellent agreement. The ranges of elemental concentrations were found to vary from 10 4 to 10 -1 mg/kg in different kinds of herbs. All herbs exhibit extraordinary enrichment capabilities from the environment for elements such as Mn, Zn, Ca, K, Mg, Cd, Cu, Pb and As. Higher contents of Cd, Pb and As in herbs may be attributed to the uptake of these elements from polluted soil due to industrial and anthropogenic activities. It was found that commercial scientific Chinese medicine, SCDBT, contains more elemental concentrations than that of herbs used in the prescription, which may indicate that possible contamination could be caused by unknown ingredients added in the process. A much higher toxic elemental content, such as Pb, Cd and As, has been found in CFH and the daily intake of these elements by the patient will exceed the PTDI values. (author)

Approximately 14.1% of Taiwanese residents use Western drugs and Chinese herbs concurrently; therefore, drug–herb interaction is critical to patient safety. This paper presents a new procedure for reducing the risk of drug interactions.Methods: Hospital computer systems are modified to ensure that drug–herb interactions are automatically detected when a TCM practitioner is writing a prescription. A pop-up reminder appears, warning of interactions, and the practitioner may adjust doses, delete herbs, or leave the prescription unchanged. A pharmacist will receive interaction information through the system and provide health education to the patient.Results: During the 2011–2013 study period, 256 patients received 891 herbal prescriptions with potential drug–herb interactions. Three of the 50 patients who concurrently used ginseng and antidiabetic drugs manifested hypoglycemia (fasting blood sugar level ≤70 mg/dL.Conclusion: Drug–herb interactions can cause adverse reactions. A computerized reminder system can enable TCM practitioners to reduce the risk of drug–herb interactions. In addition, health education for patients is crucial in avoiding adverse reaction by the interactions. Keywords: Traditional Chinese medicine, Western medicine, adverse reaction

Chinese herbal medicine has been practiced for the prevention, treatment, and cure of diseases for thousands of years. Herbal medicine involves the use of natural compounds, which have relatively complex active ingredients with varying degrees of side effects. Some of these herbal medicines are known to cause nephrotoxicity, which can be overlooked by physicians and patients due to the belief that herbal medications are innocuous. Some of the nephrotoxic components from herbs are aristolochic acids and other plant alkaloids. In addition, anthraquinones, flavonoids, and glycosides from herbs also are known to cause kidney toxicity. The kidney manifestations of nephrotoxicity associated with herbal medicine include acute kidney injury, CKD, nephrolithiasis, rhabdomyolysis, Fanconi syndrome, and urothelial carcinoma. Several factors contribute to the nephrotoxicity of herbal medicines, including the intrinsic toxicity of herbs, incorrect processing or storage, adulteration, contamination by heavy metals, incorrect dosing, and interactions between herbal medicines and medications. The exact incidence of kidney injury due to nephrotoxic herbal medicine is not known. However, clinicians should consider herbal medicine use in patients with unexplained AKI or progressive CKD. In addition, exposure to herbal medicine containing aristolochic acid may increase risk for future uroepithelial cancers, and patients require appropriate postexposure screening.

Systems Biology of Meridians, Acupoints, and Chinese Herbs in Disease

Directory of Open Access Journals (Sweden)

Li-Ling Lin

2012-01-01

Full Text Available Meridians, acupoints, and Chinese herbs are important components of traditional Chinese medicine (TCM. They have been used for disease treatment and prevention and as alternative and complementary therapies. Systems biology integrates omics data, such as transcriptional, proteomic, and metabolomics data, in order to obtain a more global and complete picture of biological activity. To further understand the existence and functions of the three components above, we reviewed relevant research in the systems biology literature and found many recent studies that indicate the value of acupuncture and Chinese herbs. Acupuncture is useful in pain moderation and relieves various symptoms arising from acute spinal cord injury and acute ischemic stroke. Moreover, Chinese herbal extracts have been linked to wound repair, the alleviation of postmenopausal osteoporosis severity, and anti-tumor effects, among others. Different acupoints, variations in treatment duration, and herbal extracts can be used to alleviate various symptoms and conditions and to regulate biological pathways by altering gene and protein expression. Our paper demonstrates how systems biology has helped to establish a platform for investigating the efficacy of TCM in treating different diseases and improving treatment strategies.

Full Text Available Due to increasing safety concerns regarding human consumption of fish products, an increasing number of medicinal chemicals are prohibited from use in aquaculture. As a result, Chinese herbal medicines are being increasingly used, coining the use of the term “green medicine.” Research shows that Chinese herbal medicines have many beneficial effects on fish, including growth promotion, enhancement of disease resistance, and improvement in meat quality. Many effective ingredients have been discovered in Chinese herbal medicines, which function to promote feed intake, improve meat flavor, and increase digestive enzyme activity. They also regulate and participate in processes that improve the specific and non-specific immunity of fish; however, the composition of Chinese herbal medicines is very complex and it is often difficult to identify the effective ingredients. This article reviews the latest research and application progress in Chinese herbal medicines regarding growth and feed utilization, immunity and disease resistance, and the meat quality of cultured fish. It also discusses research on the chemical constituents of classical Chinese medicinal herbs and problems with the application of Chinese herbal medicines in fish culture. This article concludes by proposing that future studies on Chinese herbal medicines should focus on how to cheaply refine and extract the effective ingredients in classical Chinese medicinal herbs, as well as how to use them efficiently in aquaculture.

The science of geo-authentic herbs is a characteristic discipline of traditional Chinese medicine established during thousands of years of clinical practices. It has a long history under the guidance of profound theories of traditional Chinese medicine. The words of "geo-authentic product" were derived from an administrative division unit in the ancient times, which layed stress on the good quality of products in particular regions. In ancient records of traditional Chinese medicine, the words of "geo-authentic product" were first found in Concise Herbal Foundation Compilation of the Ming dynasty, and the words of "geo-authentic herbs" were first discovered in Peony Pavilion of the late Ming dynasty. After all, clinical effect is the fundamental evaluation standard of geo-authentic herbs.

The therapeutic effect of cardiac glycosides for congestive heart failure lies in their reversible inhibition on Na+, K+-ATPase located in human myocardium. Several steroid-like compounds containing a core structure similar to cardiac glycosides have been found in many Chinese herbs and medicinal animal products conventionally used to promote blood circulation. They are putatively responsible for the therapeutic effect of those medicinal products via the same mechanism of inhibiting Na+, K+-ATPase. Inhibitory potency on Na+, K+-ATPase by ginsenosides, one of the identified steroid-like compounds, is significantly affected by sugar attachment that might cause steric hindrance of their binding to Na+, K+-ATPase. Ginsenosides with sugar moieties attached only to the C-3 position of the steroid-like structure, equivalent to the sugar position in cardiac glycosides, substantially inhibit Na+, K+-ATPase. However, their inhibitory potency is abolished when sugar moieties are linked to the C-6 or C-20 position of the steroid-like structure. In contrast, no appreciable contents of steroid-like compounds are found in danshen, a well-known Chinese herb traditionally regarded as an effective medicine promoting blood circulation. Instead, magnesium lithospermate B (MLB), the major soluble ingredient in danshen, is assumed to be responsible for the therapeutic effect by inhibiting Na+, K+-ATPase in a manner comparable to cardiac glycosides. Neuroprotective effects of cardiac glycosides, ginsenosides and MLB against ischemic stroke were accordingly observed in a cortical brain slice-based assay model. Whether the neuroprotection is also triggered by inhibition of Na+, K+-ATPase remains to be investigated. Molecular modeling suggests that cardiac glycosides, ginsenosides and MLB presumably bind to the same extracellular pocket of the Na+, K+-ATPase alpha subunit.

Cardiovascular diseases are the principal cause of death worldwide. The potentially serious adverse effects of therapeutic drugs lead to growing awareness of the role of Chinese herbal medicine in the treatment of cardiovascular diseases. Chinese herbal medicine has been widely used in many countries especially in China from antiquity; however, the mechanisms by which herbal medicine acts in the prevention and treatment of cardiovascular diseases are far from clear. In this review, we briefly describe the characteristics of Chinese herbal medicine by comparing with western medicine. Then we summarize the formulae and herbs/natural products applied in the clinic and animal studies being sorted according to the specific cardiovascular diseases. Most importantly, we elaborate the existing investigations into mechanisms by which herbal compounds act at the cellular levels, including vascular smooth muscle cells, endothelial cells, cardiomyocytes and immune cells. Future research should focus on well-designed clinic trial, in-depth mechanic study, investigations on side effects of herbs and drug interactions. Studies on developing new agents with effectiveness and safety from traditional Chinese medicine is a promising way for prevention and treatment of patients with cardiovascular diseases.

Action (" gongxiao " in Chinese) of traditional Chinese medicine (TCM) is the high recapitulation for therapeutic and health-preserving effects under the guidance of TCM theory. TCM-defined herbal properties (" yaoxing " in Chinese) had been used in this research. TCM herbal property (TCM-HP) is the high generalization and summary for actions, both of which come from long-term effective clinical practice in two thousands of years in China. However, the specific relationship between TCM-HP and action of TCM is complex and unclear from a scientific perspective. The research about this is conducive to expound the connotation of TCM-HP theory and is of important significance for the development of the TCM-HP theory. One hundred and thirty-three herbs including 88 heat-clearing herbs (HCHs) and 45 blood-activating stasis-resolving herbs (BAHRHs) were collected from reputable TCM literatures, and their corresponding TCM-HPs/actions information were collected from Chinese pharmacopoeia (2015 edition). The Kennard-Stone (K-S) algorithm was used to split 133 herbs into 100 calibration samples and 33 validation samples. Then, machine learning methods including supported vector machine (SVM), k-nearest neighbor (kNN) and deep learning methods including deep belief network (DBN), convolutional neutral network (CNN) were adopted to develop action classification models based on TCM-HP theory, respectively. In order to ensure robustness, these four classification methods were evaluated by using the method of tenfold cross validation and 20 external validation samples for prediction. As results, 72.7-100% of 33 validation samples including 17 HCHs and 16 BASRHs were correctly predicted by these four types of methods. Both of the DBN and CNN methods gave out the best results and their sensitivity, specificity, precision, accuracy were all 100.00%. Especially, the predicted results of external validation set showed that the performance of deep learning methods (DBN, CNN) were better

Nausea is special in the symptoms, and is different from hiccups and vomiting. The main symptom is that the patients throw up the indigested food from the stomach regularly--if the patients have a dinner, they will throw out it in the next morning, or if the patients have a breakfast, they will throw out it at night. Nausea is common in clinic, and different physicians may use different treatment methods for it. This disease also cannot be treated efficiently and may happen repeatedly with the western medicine. In this study, the composition principles of prescriptions in past traditional Chinese medicine for nausea were analyzed and summarized by using traditional Chinese medicine inheritance support system(V2.5), hoping to provide guidance for clinical drug use and summarize the basic rules for treatment of nausea.The prescriptions for nausea in "the prescription of traditional Chinese medicine dictionary" were selected, and the information was entered into the traditional Chinese medicine inheritance support system(TCMISS) to build a database. Data mining methods such as frequency statistics, association rules, complex system entropy clustering were used to analyze and summarize the composition principles of these prescriptions. The herb frequencies of the prescriptions were finally determined; herbs with higher use frequencies were obtained; and the association rules between herbs were found. 19 commonly used herb pairs, 10 core combinations and 10 newly developed prescriptions were found. The basic pathogenesis of nausea in traditional Chinese medicine is the weakness and coldness of spleen and stomach, and the Qi adverseness of stomach. Generations of physicians' main therapeutic method for nausea is mainly to warm the middle and invigorate the spleen, lower Qi and regulate stomach. The commonly used herbs for nausea are ginger, ginseng, large head attractylodes, tuckahoe, licorice, and appropriately supplemented with the herbs of eliminating dampness and

A Survey of Chinese Medicinal Herbal Treatment for Chemotherapy-Induced Oral Mucositis

2013-01-01

Full Text Available Oral mucositis is one of the common side effects of chemotherapy treatment with potentially severe implications. Despite several treatment approaches by conventional and complementary western medicine, the therapeutic outcome is often not satisfactory. Traditional Chinese Medicine (TCM offers empirical herbal formulas for the treatment of oral ulceration which are used in adaptation to chemotherapy-induced mucositis. While standard concepts for TCM treatment do not exist and acceptance by conventional oncologists is still low, we conducted a review to examine the evidence of Chinese herbal treatment in oral mucositis. Eighteen relevant studies on 4 single herbs, 2 combinations of 2 herbs, and 11 multiherbal prescriptions involving 3 or more compounds were included. Corresponding molecular mechanisms were investigated. The knowledge about detailed herbal mechanisms, especially in multi-herbal prescriptions is still limited. The quality of clinical trials needs further improvement. Meta-analysis on the existent database is not possible but molecular findings on Chinese medicinal herbs indicate that further research is still promising for the treatment of chemotherapy-induced oral mucositis.

The field of Traditional Chinese Medicine (TCM) represents a vast and largely untapped resource for modern medicine. Exemplified by the success of the antimalarial artemisinin, the recent years have seen a rapid increase in the understanding and application of TCM-derived herbs and formulations for evidence-based therapy. In this review, we summarise and discuss the developmental history, clinical background and molecular basis of an action for several representative TCM-derived medicines, including artemisinin, arsenic trioxide, berberine and Salvia miltiorrhiza or Danshen. Through this, we highlight important examples of how TCM-derived medicines have already contributed to modern medicine, and discuss potential avenues for further research.

Synergistic effects of Chinese herbal medicine: a comprehensive review of methodology and current research

Full Text Available Traditional Chinese medicine is an important part of primary health care in Asian countries that has utilised complex herbal formulations (consisting 2 or more medicinal herbs for treating diseases over thousands of years. There seems to be a general assumption that the synergistic therapeutic effects of Chinese herbal medicine derive from the complex interactions between the multiple bioactive components within the herbs and/or herbal formulations. However, evidence to support these synergistic effects remains weak and controversial due to several reasons, including the very complex nature of Chinese herbal medicine, misconceptions about synergy, methodological challenges to study design. In this review, we clarify the definition of synergy, identify common errors in synergy research and describe current methodological approaches to test for synergistic interaction. We discuss the strengthen and weakness of these models in the context of Chinese herbal medicine and summarise the current status of synergy research in CHM. Despite the availability of some scientific data to support the synergistic effects of multi-herbal and/or herb-drug combinations, the level of evidence remains low and the clinical relevancy of most of these findings is undetermined. There remain significant challenges in the development of suitable methods for synergistic studies of complex herbal combinations.

Study on pharmacodynamic material basis of traditional Chinese medicines is one of the key issues for the modernization of traditional Chinese medicine. Having introduced the monoclonal antibody technology into the study on pharmacodynamic material basis of traditional Chinese medicines, the author prepared the immunoaffinity chromatography column by using monoclonal antibodies in active components of traditional Chinese medicines, so as to selectively knock out the component from herbs or traditional Chinese medicine compounds, while preserving all of the other components and keeping their amount and ratio unchanged. A comparative study on pharmacokinetics and pharmacodynamics was made to explicitly reveal the correlation between the component and the main purpose of traditional Chinese medicines and compounds. The analysis on pharmacodynamic material basis of traditional Chinese medicines by using specific knockout technology with monoclonal antibodies is a new method for study pharmacodynamic material basis in line with the characteristics of traditional Chinese medicines. Its results can not only help study material basis from a new perspective, but also help find the modern scientific significance in single herb or among compounds of traditional Chinese medicines.

Traditional Chinese medicine (TCM), the ancient medicine popular in China and surrounding areas, has been recognized as a typical representative of complementary and alternative medicine. Over long period in clinical practice, especially the progress in basic research, data on the effectiveness and beneficial contribution of TCM herbs to public health and disease control have been accumulated while the quality of the evidence is generally poor. The most common clinical practice of TCM herbs is herb combination called formula which consists of several types of medicinal herbs or minerals, which is quite different from modern medicine. Definitely, tens of hundreds of compounds could be identified in even a small formula. With the regained enthusiasm on natural products based new drug R&D, the proposed multi-target drug discovery strategy, the booming of -omics technologies, and the implementation of ambitious plan of TCM modernization in China, attempts have been made to fill the gap between TCM herbs and modern drugs. However, are we heading to the right direction? Copyright © 2013 Elsevier Ltd. All rights reserved.

Chinese herbal medicine is frequently used for treating diabetic peripheral neuropathy in China. Many controlled trials have been undertaken to investigate its efficacy.This is an update of a Cochrane review that was first published in the year 2011. To assess the beneficial effects and harms of Chinese herbal medicine for people with diabetic peripheral neuropathy. On 14 May 2012, we searched the Cochrane Neuromuscular Disease Group Specialized Register CENTRAL (2012, Issue 4 in The Cochrane Library), MEDLINE (January 1966 to May 2012), EMBASE (January 1980 to May 2012), AMED (January 1985 to May 2012) and in October 2012, the Chinese Biomedical Database (CBM) (1979 to October 2012), Chinese National Knowledge Infrastructure Database (CNKI) (1979 to October 2012), and VIP Chinese Science and Technique Journals Database (1989 to October 2012). We searched for unpublished literature in the Chinese Conference Papers Database, and Chinese Dissertation Database (from inception to October 2012). There were no language or publication restrictions. We included randomised controlled trials of Chinese herbal medicine (with a minimum of four weeks treatment duration) for people with diabetic peripheral neuropathy compared with placebo, no intervention, or conventional interventions. Trials of herbal medicine plus a conventional drug versus the drug alone were also included. Two authors independently extracted data and evaluated trial quality. We contacted study authors for additional information. Forty-nine randomised trials involving 3639 participants were included. All trials were conducted and published in China. Thirty-eight different herbal medicines were tested in these trials, including four single herbs (extracts from a single herb), eight traditional Chinese patent medicines, and 26 self concocted Chinese herbal compound prescriptions. The trials reported on global symptom improvement (including improvement in numbness or pain) and changes in nerve conduction

Malignant tumor is one of the main causes for death in the world at present as well as a major disease seriously harming human health and life and restricting the social and economic development. There are many kinds of reports about traditional Chinese medicine patent prescriptions, empirical prescriptions and self-made prescriptions treating cancer, and prescription rules were often analyzed based on medication frequency. Such methods were applicable for discovering dominant experience but hard to have an innovative discovery and knowledge. In this paper, based on the traditional Chinese medicine inheritance assistance system, the software integration of mutual information improvement method, complex system entropy clustering and unsupervised entropy-level clustering data mining methods was adopted to analyze the rules of traditional Chinese medicine prescriptions for cancer. Totally 114 prescriptions were selected, the frequency of herbs in prescription was determined, and 85 core combinations and 13 new prescriptions were indentified. The traditional Chinese medicine inheritance assistance system, as a valuable traditional Chinese medicine research-supporting tool, can be used to record, manage, inquire and analyze prescription data.

Modern European monographs for quality control of Chinese herbs.

Bauer, Rudolf; Franz, Gerhard

The actual concern about the safety and efficacy of herbal drugs originating from traditional Chinese medicine (TCM) is based on observations that these medicinal plants may have a high risk potential due to insufficient definitions, problems with identity, purity and falsifications. No uniform legal status for these groups of herbal drugs currently exists in the European Union. For quality control, monographs for TCM herbs can mainly be found in the Pharmacopoeia of the Peoples Republic of China. Based on these facts the Commission of the European Pharmacopoeia decided in 2005 to establish TCM-herbal drug monographs for the most important medicinal plants imported from Far East. These new monographs had to be established and evaluated on the basis of existing monographs in the Chinese Pharmacopoeia (ChP), English edition 2005. Due to important differences in the overall features of EP and ChP, a simple adapt/adopt procedure was not feasible. Therefore, specialist groups were mandated with a corresponding working programme. Some results and actual problems related to this working programme will be presented and discussed. © Georg Thieme Verlag KG Stuttgart · New York.

Hyperthyroidism is a disease in which excessive amounts of thyroid hormones circulate in the blood. Patients, among other things suffer from tachycardia, warm moist skin and raised body temperature. The treatment of hyperthyroidism includes symptom relief and therapy with antithyroid medications, radioiodine and thyroidectomy. Medicinal herbs are used alone or in combination with antithyroid agents to treat hyperthyroidism in China and some other countries. To assess the effects of Chinese herbal medicines for treating hyperthyroidism. Studies were obtained from computerised searches of MEDLINE, EMBASE, The Cochrane Library, the Chinese Biomedical Database. Randomised controlled trials comparing the effects of Chinese herbal medicines alone with Chinese herbal medicines combined with antithyroid drugs, radioiodine or both. Three authors interviewed authors of all potentially relevant studies by telephone to verify randomisation procedures. One author entered data into a data extraction form and another author verified the results of this procedure. Thirteen relevant trials with 1770 participants were included. All of them were of low quality. Fifty-two studies still need to be assessed because the original authors could not be interviewed. None of these trials analysed mortality, health related quality of life, economic outcomes or compliance. Compared to antithyroid drugs alone the results showed that Chinese herbal medicines combined with antithyroid drugs may offer benefits in lowering relapse rates, reducing the incidence of adverse effects, relieving symptoms, improving thyroid antibody status and thyroid function. Two trials investigated Chinese herbal medicine versus radioiodine and reported improvements in anxiety, tachycardia and heat intolerance. However, thyroid function - with the exception of restored thyroid stimulating hormone (TSH) - was not significantly altered. The results suggest that traditional Chinese herbal medicines added to other routine

Functional abdominal pain syndrome (FAPS) is one of the less common functional gastrointestinal disorders. Conventional therapy has unsatisfactory response to it so people turn to Chinese medicine for help. Currently, we reviewed the whole picture of Chinese herbal medicine (CHM) clinical and basic application in the treatment of FAPS, especially the traditional Chinese medicine (TCM) syndrome, the single herb, and Chinese medicine formulae, thus to provide a solid base to further develop evidence-based study for this common gastrointestinal complaint in the future. We developed the search strategy and set the inclusion and exclusion criteria for article search. From the included articles, we totally retrieved 586 records according to our searching criteria, of which 16 were duplicate records and 291 were excluded for reasons of irrelevance. The full text of 279 articles was retrieved for detailed assessment, of which 123 were excluded for various reasons. The number one used single herb is Radix Ginseng. The most common syndrome was liver qi depression. The most frequently used classic formula was Si-Mo-Tang. This reflected the true situation of clinical practice of Chinese medicine practitioners and could be further systematically synthesized as key points of the therapeutic research for FAPS.

The use of medicinal herbs whose efficacy and toxicities are not known by HIV-positive people in Lesotho is a threat to the effectiveness of antiretroviral treatment. This study explored some medicinal herbs used by HIV-positive people in Lesotho and the reasons for their use. This was a cross sectional study based on a questionnaire distributed to purposively-sampled HIV-positive people in Leribe and Maseru districts of Lesotho. The participants' socio-demographic and clinical variables were summarized using frequency tables in Stata version 13 statistical software. Data variables for medicinal herbs used, frequency of use, uses by the participants and in the literature, parts of plants used and the method of preparation were also explored. Out of 400 questionnaires distributed to the participants, 389 were returned with data acceptable for analysis. Ages of the participants ranged from 18 to 75 years (Mean=43 + 11.6). Out of the 272 (69.9%) participants who conceded that they had used medicinal herbs at least once, 30 (7.7%) participants used medicinal herbs frequently while 242 (62.2 %) rarely used the herbs. At least 20 plant species belonging to 16 families were reportedly used by the participants. Asteraceae was the most common plant family reportedly used by the participants. Allium sativum and Dicoma anomala , reportedly used by 21.0% and 14.3% respectively, were the most commonly used medicinal herbs in this population. In addition, boosting the immune system and treating gastrointestinal ailments, apparently cited by 32% and 28% participants respectively, were the most commonly reported reasons for using medicinal herbs. A considerable proportion (69.9%) of HIV-positive people use medicinal herbs in this population, and 7.7% use them frequently. At least 20 plant species belonging to 16 families were reportedly used by the participants. HIV counselling protocols in Lesotho should emphasize the dangers of using medicinal herbs whose safety and

Impact of Chinese Herbal Medicine on American Society and Health Care System: Perspective and Concern

Full Text Available Many Americans, not completely satisfied with traditional western medicine, have turned to alternative and complementary medicine which explains the increasing popularity of the herbal products and the Chinese herbal medicine. The lack of government regulations and the increasing advertisements by the manufactures have created an impression to the common public that the natural herbal remedies are inherently safer and cheaper than conventional medicine. The skyrocketing rise of healthcare cost and the adverse reaction and side effects incurred from the prescribed drugs have both reinforced such an impression. Herbs in the USA and in many European countries have been prepared as capsules, tablets, teas, lozenges, juice extracts, tincture, and ointments. Most of the herbs are administered as a single herb in the USA and Europe. However, the traditional Chinese herbal medicine contains multiple active ingredients from various herbs and is prepared as concoctions by simmering them for hours to produce pharma-therapeutic properties useful for the treatment of a particular disease. Those prepared concoctions are taken gingerly with specific treatment purposes. In the USA and some European counties, herbs are distributed and labeled as dietary supplements and are taken by many individuals for a long period of time creating some medical and dental complex problems among them, especially in terms of anesthesia-surgery complications. This paper provides insight into basic differences in how herbs are prepared before administration to the patients in China versus a single unprepared herb sold in the USA and Europe. Also addressed are the interdisciplinary issues with health professionals, the proper regulations for better quality control of imported herbs, and the proper warning on the labels of the herbs.

Full Text Available Hepatoprotective and curative activities of aqueous extract of decoction containing 10 Chinese medicinal herbs (HPE-XA-08 were evaluated in Sprague–Dawley albino rats with liver damage induced by thioacetamide (TAA. These activities were assessed by investigating the liver enzymes level and also histopathology investigation. Increases in alkaline phosphatase (ALP and gamma-glutamyl transferase (GGT levels were observed in rats with cirrhotic liver. No significant alterations of the liver enzymes were observed following treatment with HPE-XA-08. Histopathology examination of rats treated with HPE-XA-08 at 250 mg/kg body weight, however, exhibited moderate liver protective effects. Reduced extracellular matrix (ECM proteins within the hepatocytes were noted in comparison to the cirrhotic liver. The curative effects of HPE-XA-08 were observed with marked decrease in the level of ALP (more than 3x and level of GGT (more than 2x in cirrhotic rat treated with 600 mg/kg body weight HPE-XA-08 in comparison to cirrhotic rat treated with just water diluent. Reversion of cirrhotic liver to normal liver condition in rats treated with HPE-XA-08 was observed. Results from the present study suggest that HPE-XA-08 treatment assisted in the protection from liver cirrhosis and improved the recovery of cirrhotic liver.

Non-scientific classification of Chinese herbal medicine as dietary supplement.

Science.gov (United States)

Bao, Kexin

2017-03-01

This article focuses the category status of Chinese herbal medicine in the United States where it has been mistakenly classifified as a dietary supplement. According to Yellow Emperor Canon of Internal Medicine (Huang Di Nei Jing), clinical treatment in broad sense is to apply certain poisonous medicines to fight against pathogeneses, by which all medicines have certain toxicity and side effect. From ancient times to modern society, all, or at least most, practitioners have used herbal medicine to treat patients' medical conditions. The educational curriculums in Chinese medicine (CM) comprise the courses of herbal medicine (herbology) and herbal formulae. The objective of these courses is to teach students to use herbal medicine or formulae to treat disease as materia medica. In contrast, dietary supplements are preparations intended to provide nutrients that are missing or are not consumed in suffificient quantity in a person's diet. In contrast, Chinese herbs can be toxic, which have been proven through laboratory research. Both clinical practice and research have demonstrated that Chinese herbal medicine is a special type of natural materia medica, not a dietary supplement.

Traditional Chinese herb medicines (TCHMs) have been used in the treatment of a variety of diseases for thousands of years in Asian countries. The active components of TCHMs usually exert combined synergistic therapeutic effects on multiple targets, but with less potential therapeutic effect based on routine indices than Western drugs. These complex effects make the assessment of the efficacy of TCHMs and the clarification of their underlying mechanisms very challenging, and therefore hinder their wider application and acceptance. Metabolomics is a crucial part of systems biology. It allows the quantitative measurement of large numbers of the low-molecular endogenous metabolites involved in metabolic pathways, and thus reflects the fundamental metabolism status of the body. Recently, dozens of metabolomic studies have been devoted to prove the efficacy/safety, explore the underlying mechanisms, and identify the potential biomarkers to access the action targets of TCHMs, with fruitful results. This article presents an overview of these studies, focusing on the progress made in exploring the pharmacology and toxicology of various herbal medicines. Copyright © 2015 Elsevier B.V.

The growing use of purchase online via Internet retailers favours the access to potentially toxic natural products. It also contributes to the quick dissemination of the claims made by the retailers on efficacy and safety, these claims being not always based upon reliable information. Here, we have conducted an online search to find Spanish-language retail websites for Chinese herbal medicine and we have analysed them for the quality of product information and the potential health risks. i) Online search in Google España to find Spanish-language retail websites for Chinese herbal medicine in which we analysed both the claims regarding possible health benefits and adequate safe use indications ii) Identification of potentially toxic herbs in the websites iii) Quantification of Chinese herbal medicines withdrawn by the Agencia Española de Medicamentos y Productos Sanitarios (AEMPS). 1) Only one third of the 30 Spanish-language retail websites found which sell Chinese herbal medicine observe the law, given that the other websites include illegal Western disease claims as marketing tools, 2) Five websites provide some safety information, 3) Two websites offer potentially toxic herbs and 4) Chinese herbal medicine adulterated with sibutramine, silfenafil or their analogues make a considerable percentage of the total products withdrawn by the AEMPS. Online health seekers should be warned about misinformation on retail websites for Chinese herbal medicine and directed to a Spanish government Web site for guidance in safely navigating the Internet for buying Chinese herbal medicine.

In recent years, the proportion of traditional Chinese medicine in scientific research and its clinical use increased gradually. The research result also becomes more and more valuable, but in the process of using traditional Chinese medicine, it also needs to pay more attention. With the gradual deepening of the toxicity of traditional Chinese medicine, some traditional Chinese medicines have also been found to have the potential toxicity, with the exception of some traditional toxicity Chinese medicine. Traditional Chinese medicine in the growth, processing, processing, transportation and other aspects of pollution or deterioration will also cause the side effects to the body. Clinical practice should be based on the theory of traditional Chinese medicine to guide rational drug use and follow the symptomatic medication, the principle of proper compatibility. The constitution of the patients are different, except for a few varieties of traditional Chinese medicines are natural herbs with hepatotoxicity, liver toxicity of most of the traditional Chinese medicine has idiosyncratic features. The liver plays an important role in drug metabolism. It is easy to be damaged by drugs. Therefore, the study of traditional Chinese medicine potential liver toxicity and its toxic components has become one of the basic areas of traditional Chinese medicine research. Based on the review of the literatures, this paper summarizes the clinical classification of liver toxicity, the pathogenesis of target cell injury, and systematically summarizes the mechanism of liver toxicity and toxic mechanism of traditional Chinese medicine. This paper provided ideas for the study of potential liver toxicity of traditional Chinese medicine and protection for clinical safety of traditional Chinese medicine.

2017-01-01

Full Text Available The gathering of ingredients for decoctions of traditional Chinese herbs still relies on manual dispensation, due to the irregular shape of many items and inconsistencies in weights. In this study, we developed an automatic dispensing system for Chinese herbal decoctions with the aim of reducing manpower costs and the risk of mistakes. We employed machine vision in conjunction with a robot manipulator to facilitate the grasping of ingredients. The name and formulation of the decoction are input via a human-computer interface, and the dispensing of multiple medicine packets is performed automatically. An off-line least-squared curve fitting method was used to calculate the amount of material grasped by the claws and thereby improve system efficiency as well as the accuracy of individual dosages. Experiments on the dispensing of actual ingredients demonstrate the feasibility of the proposed system.

To provide the distribution pattern and compatibility laws of the constituent herbs in prescriptions, for doctor's convenience to make decision in choosing correct herbs and prescriptions for treating respiratory disease. Classical prescriptions treating respiratory disease were selected from authoritative prescription books. Data mining methods (frequent itemsets and association rules) were used to analyze the regular patterns and compatibility laws of the constituent herbs in the selected prescriptions. A total of 562 prescriptions were selected to be studied. The result exhibited that, Radix glycyrrhizae was the most frequently used in 47.2% prescriptions, other frequently used were Semen armeniacae amarum, Fructus schisandrae Chinese, Herba ephedrae, and Radix ginseng. Herbal ephedrae was always coupled with Semen armeniacae amarum with the confidence of 73.3%, and many herbs were always accompanied by Radix glycyrrhizae with high confidence. More over, Fructus schisandrae Chinese, Herba ephedrae and Rhizoma pinelliae was most commonly used to treat cough, dyspnoea and associated sputum respectively besides Radix glycyrrhizae and Semen armeniacae amarum. The prescriptions treating dyspnoea often used double herb group of Herba ephedrae & Radix glycyrrhizae, while prescriptions treating sputum often used double herb group of Rhizoma pinelliae & Radix glycyrrhizae and Rhizoma pinelliae & Semen armeniacae amarum, triple herb groups of Rhizoma pinelliae & Semen armeniacae amarum & Radix glycyrrhizae and Pericarpium citri reticulatae & Rhizoma pinelliae & Radix glycyrrhizae. The prescriptions treating respiratory disease showed common compatibility laws in using herbs and special compatibility laws for treating different respiratory symptoms. These principle patterns and special compatibility laws reported here could be useful for doctors to choose correct herbs and prescriptions in treating respiratory disease.

In order to put forward new method and basis to remove pesticide residues in Chinese herbs, the influence factors such as irradiation doses and water content of electron beam irradiation on degradation efficiency of carbamate and organophosphorous pesticides in ginseng are investigated. Additionally, the irradiation degradation of two pesticides treated with the same dose in several traditional Chinese herbal medicines like Baifuling is also studied. The irradiation can effectively degrade these pesticide residues in herbal medicines; the efficiency of lower doses are inferior to higher doses. The degradation rate rises when dose increases, and varies among 4 ∼ 10 kGy in different Chinese herbal medicines. The degradation efficiency of organophosphorous pesticides is better than those of carbamate pesticides. (authors)

It is a common sense that chewing a mint leaf causes a cold feeling, while masticating a piece of ginger root is associated with a hot sensation. The Traditional Chinese Medicine has termed this phenomenon as cold and hot properties of herbs and applied them in treating certain human diseases successfully for thousands of years. Here, we have developed an Animal Thermotropism Behavior Surveillance System, and by using this device and other approaches, we not only verified the existence of, but also characterized and quantitated the cold and hot properties of medicinal herbs in animal behavioral experiments. The results suggested that the hot and cold properties of herbal drugs indeed correlated with the alteration of animal behavior in search for residence temperature. Copyright © 2010.

This chapter summarizes recent developments in preclinical and clinical research on Chinese herbal medicines and their neurochemical mechanism of action for the treatment of drug addiction. We searched Chinese and English scientific literature and selected several kinds of Chinese herbal medicines that have beneficial effects on drug addiction. Ginseng (Renshen) may be clinically useful for the prevention of opioid abuse and dependence. Rhizoma Corydalis (Yanhusuo) may be used to prevent relapse to chronic drug dependence. Alkaloids of Uncaria rhynchophylla (Gouteng) appear to have positive effects on methamphetamine and ketamine addiction. Both Salvia miltiorrhiza (Danshen) and Radix Pueraiae (Gegen) have beneficial inhibitory effects on alcohol intake. Sinomenine has been shown to have preventive and curative effects on opioid dependence. l-Stepholidine, an alkaloid extract of the Chinese herb Stephania intermedia (Rulan), attenuated the acquisition, maintenance, and reacquisition of morphine-induced conditioned place preference and antagonized the heroin-induced reinstatement of heroin seeking. Traditional Chinese herbal medicines may be used to complement current treatments for drug addiction, including withdrawal and relapse. As the molecular mechanisms of action of traditional Chinese herbal medicines are elucidated, further advances in their use for the treatment of drug addiction are promising. © 2017 Elsevier Inc.

To assess the patterns of use of Chinese herbal medicine (CHM) used by women in Taiwan to treat menopausal symptoms. A retrospective review of the records of women who received CHM therapies for menopausal symptoms at the Traditional Medicine Center, Veterans General Hospital, Taipei, between January 2003 and December 2006. The average number of therapies per prescription, dosage, and duration of the prescription were recorded. The most commonly prescribed herbs and formulae were also recorded. Data were analyzed using descriptive statistics. The records of 3432 women who were administered a total of 19370 CHMs to treat symptoms of the menopause were reviewed. The average number of drugs per prescription was 5.64. Most of the prescriptions (97.1%) were prescribed to be taken 3 times a day. The most commonly prescribed Chinese herb was Leonurus heterophyllus. Jia-Wey-Shiau-Yau-San was the most commonly prescribed Chinese herbal formula. CHM is commonly used in Taiwan for the treatment of menopausal symptoms. The efficacy and safety of CHM drugs used for the management of menopausal symptoms require further study.

Good medicinal herbs, good drugs. Good evaluation method and indices are the prerequisite of good medicinal herbs. However, there exist numerous indices for quality evaluation and control in Chinese medicinal materials. However, most of these indices are non-interrelated each other, as well as having little relationship with efficiency and safety. The results of different evaluatior methods may not be consistent, even contradictory. Considering the complex material properties of Chinese medicinal materials, single method and index is difficult to objectively and comprehensively reflect the quality. Therefore, it is essential to explore the integrated evaluation methods. In this paper, oriented by the integrated evaluation strategies for traditional Chinese medicine quality, a new method called integrated quality index (IQI) by the integration of empirical evaluation, chemical evaluation, and biological evaluation was proposed. In addition, a study case of hypertoxic herb Aconitum carmichaelii Debx. was provided to explain this method in detail. The results suggested that in the view of specifications, the average weight of Jiangyou aconite was the greatest, followed by Weishan aconite, Butuo aconite, Hanzhong aconite, and Anxian aconite; from the point of chemical components, Jiangyou aconite had the characteristic with strong efficacy and weak toxicity, next was Hanzhong aconite, Butuo aconite, Weishan aconite, and Anxian aconite; taking toxicity price as the index, Hanzhong aconite and Jiangyou aconite have the lower toxicity, while Butuo aconite, Weishan aconite, and Anxian aconite have the relatively higher one. After the normalization and integration of evaluation results, we calculated the IQI value of Jiangyou aconite, Hanzhong aconite, Butuo aconite, Weishan aconite, and Anxian aconite were 0.842 +/- 0.091, 0.597 +/- 0.047, 0.442 +/- 0.033, 0.454 +/- 0.038, 0.170 +/- 0.021, respectively. The quality of Jiangyou aconite is significantly better than the

Insomnia is a common complaint in the general population. Interest in the use of alternative treatments for insomnia is increasing exponentially and is fairly common in Taiwan. We undertook a survey to define the drug utilization patterns of Chinese herbal medicines (CM) for insomnia in Taiwan. The survey was conducted over a period of 4 years, from January 2003 to December 2006. Outpatients with primary insomnia and being treated with CM were studied. Core drug-use indicators were the number of CM items per prescription, the dosing frequency and duration of CM prescriptions, the most common prescribed CM herbs and CM formulae used. Six thousand eight hundred and sixty patients, using 37,046 CM herb items, were screened during the study period. The average CM items per prescription was 5.40. Most of prescriptions (95.23%) were prescribed for administration three times a day. The most often prescribed Chinese herbal products were Hong-Hwa (Carthamus tinctorius) and Jia-Wey-Shiau-Yau-San, which includes Angelica sinensis, Atractylodes macrocephala, Paeonia lactiflora, Bupleurum chinense, and Poria coco. This is the first extensive survey examining the drug utilization patterns of Chinese herbal medicines in the treatment of insomnia. Although the data were generated in Taiwan, the herbs and practices identified are likely to be widely generalizable wherever Chinese herbal remedies are used for insomnia. Multiple herbs and complex formulae were commonly used. The baseline data generated should be of use in informing subsequent studies, including those aimed at a thorough evaluation of the herbs' effectiveness.

Gardeniae Fructus, which is widely used in health foods and clinical medicines, is a type of edible food and medicine. Dictionary of traditional Chinese medicine prescriptions provides good materials for prescription analysis and the R&D of traditional Chinese medicines. The composition regularity of formulae containing Gardeniae Fructus in dictionary of traditional Chinese medicine prescriptions was analyzed on the basis of the traditional Chinese medicine inheritance support system(TCMISS), in order to provide reference for clinical application and the R&D of new drugs. TCMISS was applied to establish a database of prescriptions containing Gardeniae Fructus. The software's frequency statistics and association rules and other date mining technologies were adopted to analyze commonly used drugs, combination rules and core combined formulae containing Gardeniae Fructus. Totally 3 523 prescriptions were included in this study and involved 1 725 Chinese herbs. With a support degree of 352(10%) and confidence coefficient of 90%, 57 most commonly used drug combinations were screened. Drugs adopted in core combinations were relatively concentrated and selected according to definite composition methods. They were used to mainly treat 18 diseases. Gardeniae Fructus have often been combined with herbs for heat-clearing and detoxification, expelling pathogenic wind, relieving exterior syndrome, invigorating the circulation of blood and gas and promoting blood circulation for removing blood stasis to mainly treat jaundice, typhoid, headache and other syndromes.

Full Text Available Background. Data about the use of medicinal herbs for selftreatment in our population is sparse. Therefore the aim of our survey was to investigate the measures taken by patients with four most frequent symptoms, which medicinal herbs they used and where they got them.Methods. In the streets of the city of Velenje 184 randomly chosen adults were asked about the measures to cope with their four most common symptoms: abdominal pain, headache, diarrhoea and raised body temperature.Results. 72 percent of people surveyed use medicinal herbs. The use increases with advancing age. There are no differences regarding their education. It has been found that the pill is mostly used while the medicinal herbs take the third place. The most frequently used herb is camomile (Matricaria chamomilla. The herbs are mainly provided by the users themselves.Conclusions. Medicinal herbs are often used in combination with conventional therapy, without proper knowledge of their side effects and the harm of potentional misuse. The physicians are mainly not aware of their use among the patients. The importance of this problem for the public health service is thus essential.

Aristolochic acids (AAs) widely exist in such plants as Aristolochia and Asarum. The renal toxicity of AAs as well as its carcinogenicity to urinary system have been widely known. In 2003 and 2004, China prohibited the use of Aristolochiae Radix, Aristolochiae Manshuriensis Caulis and Aristolochiae Fangchi Radix, and required administering other AAs-containing medicines in accordance with the regulations for prescription drugs. In this paper, we retrieved literatures on the content determination of AAs in recent 10 years in China. It suggested that the AAs content is lower in Asarum herb, especially in its roots and rhizomes, and most of which do not show detectable amount of AA-I. Some of traditional Chinese medicines show fairly small amount of detectable AA-I. The AAs content in Aristolochia herb (including Fructus Aristolochiae, kaempfer dutchmanspipe root) is relatively high; however, there are fewer literatures for studying the content determination of AAs in Chinese patent medicines. There were many factors affecting AAs content, including the parts used, origins, processing methods, extraction process. It suggested that we should pay attention to the toxicity of Chinese medicines containing AAs and use these decoction pieces and traditional Chinese medicines cautiously. In addition, basic studies for the origins, processing methods and extraction process of Chinese patent medicines containing AAs, as well as supervision and detection of AAs content in traditional Chinese medicinal materials, decoction pieces and Chinese patent medicines shall be strengthened for reducing medication risk and guaranteeing clinical medication safety.

Traditional Chinese medicines have been widely investigated for the treatment of Alzheimer's disease (AD) because none of the current therapies-either the cholinesterase inhibitors or antagonist of N-methyl-d-aspartate receptors-has profound effects on halting the progression of AD. In recent years, scientists have isolated many active compounds from herbs, which can alleviate dementia and neurodegenerative syndrome with fewer side effects than conventional drugs and, thus, are regarded as promising drug candidates for AD therapy. In this review, we summarize the latest research progress on six herbs for AD therapy-Huperzia serrata, Amaryllidaceae family, Ginkgo biloba, Uncaria rhynchophylla, Polygala tenuifolia, and Salvia officinalis-and focus on the analysis of their active components and possible mechanisms of pharmacological actions on AD.

There is a recognized challenge in analyzing traditional Chinese medicine formulas because of their complex chemical compositions. The application of modern analytical techniques such as high-performance liquid chromatography coupled with a tandem mass spectrometry has improved the characterization of various compounds from traditional Chinese medicine formulas significantly. This study aims to conduct a bibliometric analysis to recognize the overall trend of high-performance liquid chromatography coupled with tandem mass spectrometry approaches in the analysis of traditional Chinese medicine formulas, its significance and possible underlying interactions between individual herbs in these formulas. Electronic databases were searched systematically, and the identified studies were collected and analyzed using Microsoft Access 2010, Graph Pad 5.0 software and Ucinet software package. 338 publications between 1997 and 2015 were identified, and analyzed in terms of annual growth and accumulated publications, top journals, forms of traditional Chinese medicine preparations and highly studied formulas and single herbs, as well as social network analysis of single herbs. There is a significant increase trend in using high-performance liquid chromatography coupled with tandem mass spectrometry related techniques in analysis of commonly used forms of traditional Chinese medicine formulas in the last 3 years. Stringent quality control is of great significance for the modernization and globalization of traditional Chinese medicine, and this bibliometric analysis provided the first and comprehensive summary within this field. © 2016 WILEY-VCH Verlag GmbH & Co.

Full Text Available Myocardial ischemia-reperfusion (MIR injury is a major contributor to the morbidity and mortality associated with coronary artery disease, which accounts for approximately 450,000 deaths a year in the United States alone. Chinese herbal medicine, especially combined herbal formulations, has been widely used in traditional Chinese medicine for the treatment of myocardial infarction for hundreds of years. While the efficacy of Chinese herbal medicine is well documented, the underlying molecular mechanisms remain elusive. In this review, we highlight recent studies which are focused on elucidating the cellular and molecular mechanisms using extracted compounds, single herbs, or herbal formulations in experimental settings. These studies represent recent efforts to bridge the gap between the enigma of ancient Chinese herbal medicine and the concepts of modern cell and molecular biology in the treatment of myocardial infarction.

1998-01-01

The feasibility of sterilizing traditional Chinese medicines (TCMs) by γ-irradiation has been systematically evaluated by the biological, toxicological and physicochemical tests on irradiated hundreds of TCMs. Those TCMs investigated in general show no significant biological or toxicological changes after irradiation, yet physicochemical changes are detectable in some irradiated TCMs, and water in TCMs enhances the effects. Those results obtained from radiolysis of some major effective components of TCMs in aqueous or ethanolic solutions reveal that the site selection of radiolytically generated radicals follows the example of simple compounds with same function groups. Wholesomeness and chemical clearance present a bright future to sterilizing TCMs by γ irradiation, however, some important measures and steps should be adopted: (1) The producers must strictly execute manufacturing procedure to reduce microbiological contamination thus lower the applied dose for sterilization which is recommended to be controlled under 5, 7 or 10 kGy for dry herb, 7 kGy for herbal medicine and 5 kGy for some special herbal medicine; (2) Herb to be sterilized by γ-irradiation should exist in possible dry state; (3) Powder TCMs is recommended to mix with honey forming bolus, which can minimize the decomposition of herb

A wealth of information is emerging about the impact of gut microbiota on human health and diseases such as cardiovascular diseases, obesity and diabetes. As we learn more, we find out the gut microbiota has the potential as new territory for drug targeting. Some novel therapeutic approaches could be developed through reshaping the commensal microbial structure using combinations of different agents. The gut microbiota also affects drug metabolism, directly and indirectly, particularly towards the orally administered drugs. Herbal products have become the basis of traditional medicines such as traditional Chinese medicine and also been being considered valuable materials in modern drug discovery. Of note, low oral bioavailability but high bioactivity is a conundrum not yet solved for some herbs. Since most of herbal products are orally administered, the herbs' constituents are inevitably exposed to the intestinal microbiota and the interplays between herbal constituents and gut microbiota are expected. Emerging explorations of herb-microbiota interactions have an opportunity to revolutionize the way we view herbal therapeutics. The present review aims to provide information regarding the health promotion and/or disease prevention by the interplay between traditional herbs with low bioavailability and gut microbiota through gut microbiota via two different types of mechanisms: (1) influencing the composition of gut microbiota by herbs and (2) metabolic reactions of herbal constituents by gut microbiota. The major data bases (PubMed and Web of Science) were searched using "gut microbiota", "intestinal microbiota", "gut flora", "intestinal flora", "gut microflora", "intestinal microflora", "herb", "Chinese medicine", "traditional medicine", or "herbal medicine" as keywords to find out studies regarding herb-microbiota interactions. The Chinese Pharmacopoeia (2010 edition, Volume I) was also used to collect the data of commonly used medicinal herbs and their quality

To study the effects of the ingredients from Chinese herbs with the nature of cold or hot on the expression of TRPV1 and TRPM8. The effects of ingredients from herbs on primary culture DRG neurons are observed in vitro. The expression quantity of gene is detected by the method of real time PCR. the 2 (-deltadeltaCT) method is applied to analyze the data. Ingredients from herbs with the nature of cold up-regulate the expression level of TRPV1 and down-regulate that of TRPM8, especially under the temperature condition of 39 degrees C; while ingredients from herbs with the nature of hot up-regulate the expression level of TRPM8 and down-regulated that of TRPV1, which is more significant under the temperature condition of 19 degrees C. The regulatory changes of TRPV1 and TRPM8 mRNA expression induced by the chemical ingredients might be related to the cold and hot natures of the herbs from which the ingredients are extracted. And this could be one of the therapeutic mechanisms for the treatment of Chinese herbal medicines to cold- and heat-related diseases.

Microwave assisted extraction (MAE) is a combination of a microwave technique and conventional solvent extraction used in the modernization of traditional Chinese medicine. The effective component of medicinal herbs is mostly cellular material which can be released via solvent extraction. The material is diffused to solvents via the porous membrane wall. The structure of herb morphology and characteristics of the solute's molecular weight play an important role in the extraction process of target compounds. Astragalus pieces were chosen for this study in which an ultra-filtration membrane method was used to determine the molecular weight distribution characteristics of Astragalus water extraction liquid in the process of MAE. The fine structure of matrix materials was also characterized by scanning election microscopy (SEM). The phenomenon of mass flow and mass transfer in the plant porous media was discussed along with the enhancement mechanism of microwave field on medicinal plant solvent extraction. The results showed that the water-soluble components in the parenchyma cells of Astragalus pieces pass through the plasmodesma with a diameter of 10 nm to adjacent cell, then through an aperture with a diameter of 0.1 {mu}m to 1 {mu}m into a trachea with a diameter of about 10 {mu}m. The water-soluble components then come onto the surface of matrix material and the main solution via the trachea. The main mass transfer occurs by the trachea and its aperture. It was concluded that in order to promote the dissolution of effective components in medicinal herb in the extraction process, a suitable extraction technology is needed to maintain the permeability of transportation tissue and parenchyma in materials. 11 refs., 1 tab., 3 figs.

2011-01-01

Sasang constitutional medicine (SCM), traditional Chinese medicine (TCM) and Ayurveda are three different forms of Asian traditional medicine. Although these traditions share a lot in common as holistic medicines, the different philosophical foundations found in each confer distinguishing attributes and unique qualities. SCM is based on a constitution-based approach, and is in this way relatively more similar to the Ayurvedic tradition than to the TCM, although many of the basic SCM theories were originally derived from TCM, a syndrome-based medicine. SCM and TCM use the same botanical materials that are distributed mainly in the East Asian region, but the basic principles of usage and the underlying rationale are completely different from each other. Meanwhile, the principles of the Ayurvedic use of botanical resources are very similar to those seen in SCM, but the medicinal herbs used in Ayurveda generally originate from the West Asian region which displays a different spectrum of flora.

The shift in consumers' preferences from synthetic to 'natural' products has led to a resurgence of interest in medicinal plants, particularly in developing countries. However, research data about consumers' preferences for particular products is hard to find. The main objective of this study was to contribute to the general understanding of consumers' intention for selecting medicinal herbs for consumption. Factors underpinning consumers' acceptance of medicinal herbs were studied with the technology acceptance model (TAM) in Rasht City of Iran using a structured questionnaire. Most respondents had low to moderate familiarity with consumption of medicinal herbs. However, about half of the respondents (47.5%) showed a high level of acceptance of medicinal herbs. Herbs like spearmint (Mentha spicata L.), spinach (Spinacia oleracea L.), basil (Ocimum basilicum L.), Damask rose (Rosa × damascena Herrm.), saffron (Crocus sativus L.), cinnamon (Cinnamomum verum J.Presl), flixweed [Descurainia sophia (L.) Webb ex Prantl], red feathers (Echium amoenum Fisch. & C.A.Mey.), and green tea [Camellia sinensis (L.) Kuntze] had the highest consumption rate among the majority (over 75%) of citizens of Rasht. The highest rate of perceived usefulness of medicinal herbs was related to their perceived role in healing diseases. The variable of importance of use of medicinal herbs had the strongest direct effect and the variables of perceived usefulness and attitude towards use had the second and third strongest direct effect on the acceptance of medicinal herbs' use at p acceptance of medicinal herbs and may serve as a benchmark for future research and evaluation concerning the use of medicinal herbs over time. For plant producers, more effective and targeted crop development should be encouraged, whereas for retailers better marketing and delivery strategies should be sought.

Dongeuibogam (DongYiBaoGian), one of the most important books in Korean medicine, comprises a comprehensive summary of all traditional medicines of North-East Asia before the 17th century. This medicinal literature was mined to establish a list of candidate herbs to treat Parkinson-related rigidity. A systematic search for terms describing Parkinson-related rigidity and candidate prescriptions for the treatment of Parkinson-related rigidity in the Dongeuibogam was performed. A high-frequency medicinal herb combination group and candidates for the treatment of Parkinson-related rigidity were also selected through an analysis of medicinal herb combination frequencies. The existing literature pertaining to the potential effects of candidate herbs for Parkinson-related rigidity was reviewed. Ten medicinal herb candidates for the treatment of Parkinson-related rigidity were selected, and their respective precedent studies were analyzed.

Full Text Available BACKGROUND: Herb-drug interactions are an important issue in drug safety and clinical practice. The aim of this epidemiological study was to characterize associations of clinical outcomes with concomitant herbal and antipsychotic use in patients with schizophrenia. METHODS AND FINDINGS: In this retrospective, cross-sectional study, 1795 patients with schizophrenia who were randomly selected from 17 psychiatric hospitals in China were interviewed face-to-face using a structured questionnaire. Association analyses were conducted to examine correlates between Chinese medicine (CM use and demographic, clinical variables, antipsychotic medication mode, and clinical outcomes. The prevalence of concomitant CM and antipsychotic treatment was 36.4% [95% confidence interval (95% CI 34.2%-38.6%]. Patients using concomitant CM had a significantly greater chance of improved outcomes than non-CM use (61.1% vs. 34.3%, OR = 3.44, 95% CI 2.80-4.24. However, a small but significant number of patients treated concomitantly with CM had a greater risk of developing worse outcomes (7.2% vs. 4.4%, OR = 2.06, 95% CI 2.06-4.83. Significant predictors for concomitant CM treatment-associated outcomes were residence in urban areas, paranoid psychosis, and exceeding 3 months of CM use. Herbal medicine regimens containing Radix Bupleuri, Fructus Gardenia, Fructus Schisandrae, Radix Rehmanniae, Akebia Caulis, and Semen Plantaginis in concomitant use with quetiapine, clozapine, and olanzepine were associated with nearly 60% of the risk of adverse outcomes. CONCLUSIONS: Concomitant herbal and antipsychotic treatment could produce either beneficial or adverse clinical effects in schizophrenic population. Potential herb-drug pharmacokinetic interactions need to be further evaluated.

Background Traditional Chinese medicine (TCM) and Western medicine are both popular in Taiwan. Approximately 14.1% of Taiwanese residents use Western drugs and Chinese herbs concurrently; therefore, drug–herb interaction is critical to patient safety. This paper presents a new procedure for reducing the risk of drug interactions. Methods Hospital computer systems are modified to ensure that drug–herb interactions are automatically detected when a TCM practitioner is writing a prescription. A pop-up reminder appears, warning of interactions, and the practitioner may adjust doses, delete herbs, or leave the prescription unchanged. A pharmacist will receive interaction information through the system and provide health education to the patient. Results During the 2011–2013 study period, 256 patients received 891 herbal prescriptions with potential drug–herb interactions. Three of the 50 patients who concurrently used ginseng and antidiabetic drugs manifested hypoglycemia (fasting blood sugar level ≤70 mg/dL). Conclusion Drug–herb interactions can cause adverse reactions. A computerized reminder system can enable TCM practitioners to reduce the risk of drug–herb interactions. In addition, health education for patients is crucial in avoiding adverse reaction by the interactions. PMID:25733840

As utilization of medicinal herbs in food and bio-industry increases, mass production and the supply of herbs with a high quality are required. As the use of fumigants and preservatives for herbs is being restricted, safe hygienic technologies are demanded. To consider the possibility of the application of irradiation technology for this purpose, the genotoxicological safety and stability of the active components of the γ-irradiated Paeoniae Radix were studied. The herb was irradiated with γ-rays at a practical dosage of 10 kGy, and then it was extracted with hot water. The genotoxicity of the extract of the irradiated herb was examined in two short-term in vitro tests: (1) Ames test in Salmonella typhimurium; (2) Micronucleus test in cultured Chinese hamster ovary (CHO) cells. The extract of the irradiated herb did not show mutagenicity in the Ames test of the Salmonella reverse mutation assay, and did not show cytogenetic toxicity in the culture of the CHO cells. HPLC chromatogram of paeoniflorin in the irradiated Paeoniae Radix was similar with that of the non-irradiated sample. The quantity of paeoniflorin did not change significantly with irradiation. These results suggest that γ-irradiated Paeoniae Radix is toxicologically safe and chemically stable

Type 2 diabetes mellitus (T2DM) occurs in 95% of the diabetic populations. Management of T2DM is a challenge. Traditional Chinese medicines (TCM) are usually served as adjuvants used to improve diabetic syndromes in combination of routine antidiabetic drugs. For single-herb prescriptions, Ginseng, Bitter melon, Golden Thread, Fenugreek, Garlic, and Cinnamon might have antidiabetic effects in T2DM patients. Among 30 antidiabetic formulas approved by the State Food and Drugs Administrator of China, top 10 of the most frequently prescribed herbs are Membranous Milkvetch Root, Rehmannia Root, Mongolian Snakegourd Root, Ginseng, Chinese Magnoliavine Fruit, Kudzuvine Root, Dwarf Lilyturf Tuber, Common Anemarrhena Rhizome, Barbary Wolfberry Fruit, and India Bread, which mainly guided by the theory of TCM. Their action mechanisms are related to improve insulin sensitivity, stimulate insulin secretion, protect pancreatic islets, and even inhibit intake of intestinal carbohydrates. However, it is very difficult to determine antihyperglycemic components of TCM. Nevertheless, TCM are becoming popular complementary and alternative medicine in treatment of syndromes of T2DM. In the future, it requires further validation of phytochemical, pharmacological, and clinical natures of TCM in T2DM in the future studies, especially for those herbs with a high prescription frequency.

The rapidly increasing incidence of diabetes mellitus (DM) is becoming a major public health issue. As one of the important parts in complementary and alternative therapies, traditional Chinese medicine (TCM) is promising in treating DM. In this review, we summarize new thoughts on treating DM that aim to improve the clinical efficacy of TCM from the perspectives of principle, methods, formula, herbs, and doses. Our approach is as follows: principle: we use a combination of symptoms, syndromes, and diseases as a new mode for treating diabetes; methods: emphasizing heat-clearing in the early and middle stage of T2DM and invigorating blood circulation throughout the whole process of T2DM are two innovative methods to treat T2DM; formulas and herbs: choosing formulas and herbs based on the combination of TCM theory and current medicine. We will emphasize four strategies to help doctors choose formulas and herbs, including treatment based on syndrome differentiation, choosing herbs of bitter and sour flavors to counteract sweet flavor, choosing formulas and herbs aimed at main symptoms, and using modern pharmacological achievements in clinical practice; dose: reasonable drug dose plays an important role in the treatment of DM and a close relationship exists between dose and clinical efficacy.

Medicinal herbs have a very important role in health protection and disease control, and have been used in health foods. Polycyclic aromatic hydrocarbons (PAHs) have carcinogenic, biological and mutagenic effects. In this paper, the content of 16 PAHs as representative contaminants in nine Chinese medicinal herbs, as additives for health foods, was investigated in order to ensure food safety from this source. A highly sensitive isotope dilution-gas chromatography-tandem mass spectrometry (ID-GC-MS/MS) method combined with gel permeation chromatography (GPC) and solid-phase extraction (SPE) was developed. Calibration curves showed good linearity for all PAHs (R² > 0.999), and the limit of quantification (LOQ) ranged from 0.42 to 2.7 µg kg⁻¹. Average recoveries for these compounds were in the range of 52.5-117%, 52.6-119% and 81.4-108% at the concentrations of 10, 50 and 250 µg kg⁻¹ with RSD of 1.8-15%, 0.9-15% and 1.0-15%, respectively. The proposed method was used for the analysis of nine Chinese medicinal herbs. Total levels of PAHs varied from 98.2 µg kg⁻¹ (cassia seed) to 2245 µg kg⁻¹ (eucommia bark). The highest level was found for phenanthrene (Phe) in liquorice root (631.3 µg kg⁻¹), indigowoad leaf (551.0 µg kg⁻¹), rose flower (435.2 µg kg⁻¹) and eucommia bark (432.3 µg kg⁻¹). The proposed method could provide a useful basis for safety monitoring of herbs and risk management for PAHs in the health food industry.

The efficacy and safety of application of traditional Chinese medicines (TCMs) during the pregnancy is a hotspot among scholars. However, the traditional pregnancy contraindication content has certain historical limitations, and cannot meet the needs of the current pregnant women for rational drug use. We need to refine and interpret it with modern medical science. In this paper, we summarized the ancient and modern knowledge about pregnancy contradiction and tried to establish a grading safety system, based on the actual clinical practices and thte medication grading concept of western medicines. Specifically speaking, in this paper, we compared the connotations of forbidden/contradiction and cautious use, and focused on the safe herbs that included in the prescriptions for dietary therapy. Meanwhile, in this paper, we summarized the core content of the famous theories of ″You Gu Wu Yun (pregnancy disease)″ and ″Shuai Qi Da Ban Er Zhi (therapy during pregnancy)″, and studied the dangerous and unknown risk of TCMs during pregnancy. At last, a five-grade safety system of TCMs applied on the pregnant women was established, including forbidden, contraindicated, cautious, uncertain and available medicines. We classified medicines with the embryotoxicity (e.g. teratogenic, mutagenic, ageneisa), the traditional toxicity (e.g. abortion), the fierce herbal property (e.g. removing blood stasis, promoting Qi circulation) and reliable edible medicinal herbs. We also place an ″uncertain″ category based on objective reality. Meanwhile, 33 sample TCMs were preliminarily determined. This paper proposed the preference and ideas for the rational herbal use in pregnancy. Copyright© by the Chinese Pharmaceutical Association.

Traditional Chinese Medicine for Refractory Nephrotic Syndrome: Strategies and Promising Treatments

Science.gov (United States)

Tu, Yuan-Chao

2018-01-01

Refractory nephrotic syndrome (RNS) is an immune-related kidney disease with poor clinical outcomes. Standard treatments include corticosteroids as the initial therapy and other immunosuppressants as second-line options. A substantial proportion of patients with RNS are resistant to or dependent on immunosuppressive drugs and often experience unremitting edema and proteinuria, cycles of remission and relapse, and/or serious adverse events due to long-term immunosuppression. Traditional Chinese medicine has a long history of treating complicated kidney diseases and holds great potential for providing effective treatments for RNS. This review describes the Chinese medical theories relating to the pathogenesis of RNS and discusses the strategies and treatment options using Chinese herbal medicine. Available preclinical and clinical evidence strongly supports the integration of traditional Chinese medicine and Western medicine for improving the outcome of RNS. Herbal medicine such as Astragalus membranaceus, Stephania tetrandra S. Moore, and Tripterygium wilfordii Hook F can serve as the alternative therapy when patients fail to respond to immunosuppression or as the complementary therapy to improve therapeutic efficacy and reduce side effects of immunosuppressive agents. Wuzhi capsules (Schisandra sphenanthera extract) with tacrolimus and tetrandrine with corticosteroids are two herb-drug combinations that have shown great promise and warrant further studies.

Using Chinese herbal medicines during pregnancy and postpartum is common in the Chinese community. The purpose of this current study is to explore the use of Chinese herbal medicines by women during pregnancy and postpartum in Taiwan. It is an on-going prospective longitudinal study design. We used multistage stratified systematic sampling to recruit 24,200 pairs, postpartum women and newborns, from the Taiwan national birth register in 2005. Subjects underwent a home interview 6 months after their deliveries between June 2005 and July 2006. A structured questionnaire was successfully administered to 87.8% of the sampled population. At least one Chinese herbal medicine was used by 33.6% and 87.7% of the interviewed subjects during pregnancy and the postpartum period, respectively. An-Tai-Yin, Pearl powder, and Huanglian were the most commonly used during pregnancy, while Shen-Hua-Tang and Suz-Wu-Tang were the most commonly used by postpartum women. Pregnant women aged 20-34, with high education, threatened abortion, chronic disease, and primipara appeared to use more Chinese herbal medicines than others in the sample. Postpartum women with high education, primipara, normal spontaneous delivery, and breastfeeding were found to use more Chinese herbal medicines; but women with pregnancy-related illness used less. Chinese herbal medicines are frequently used by women during pregnancy and the postpartum period in Taiwan and those with high education and primipara used more such herbs. Due to limited safety information on these herbs, we would advise caution regarding their use either during pregnancy or postpartum breastfeeding period. Moreover, it is important for nurses/midwifes enquiring about such habits, and providing the adequate education to women during prenatal and postpartum care to prevent potential side effects.

The use of drugs derived from plants is a cornerstone of Traditional Chinese Medicine (TCM). Yet, too little is known about risk and safety of Chinese medicinal drugs (CMD). Therefore, the TCM hospital Bad Kötzting has developed a quality control and complication screening programme in order to ensure a safe administration of TCM drugs to their patients. All Chinese medicinal drugs delivered to the hospital between September 1, 2012 and December 31, 2013 entered the quality control program and were screened for microbial contamination, aflatoxin, pesticides and heavy metals. A routinely applied complication screening programme monitored liver enzymes in all patients. Case causality assessment by CIOMS scale and identification of admitted herbs were conducted. Additionally, side effects of patients were identified by a routinely performed web-based documentation system. In 5 of 23 investigated samples (21.7%) the initial testing showed microbial contamination (2), pesticide (2) and heavy metals (1). The drugs were tested for authenticity and adulterations, respectively. All 994 patients (mean age 52.6 years; 72.6% female) admitted were available for analysis. 448 (45.1%) of all patients reported having perceived at least one side effect of treatment. They experienced mainly gastrointestinal symptoms (13.6%), neurovegetative symptoms (10.8 %), temporary deteriorations of pain (8.8%), diarrhoea (5.9%), nausea (1.6%) and vomiting (0.5%). Further, 6 patients with a more than 2-fold elevation (compared to maximum normal value or elevated admission values) of ALT were found in the systematic laboratory control with a non-conclusive causality assessment for TCM-drugs. Approximate incidence rates and analysed drugs associated with liver damage revealed a low rate of liver injury. Patients should be informed of the gastrointestinal symptoms caused by and potential hepatotoxicity of TCM herbs. © 2016 S. Karger GmbH, Freiburg.

In this research, the natural radioactivity concentrations and their respective annual effective dose of the naturally occurring radionuclides 226 Ra, 228 Ra and 40 K in selected medicinal herb plants were investigated. Seven kinds of popular Thai medicinal herb plants had been studied: turmeric, ginger, safflower, moringa, gotu kola, garlic and alexandria senna. The radiological risk associated with the use of these medicinal plants was assessed. The activity concentrations of 226 Ra, 228 Ra and 40 K were determined using the gamma-ray spectrometry technique. The radioactivity concentrations were found to range from less than 0.20 to 6.67 Bqkg -1 for 226 Ra, less than 0.10 to 9.69 Bqkg -1 for 228 Ra, and from 159.42 to 1216.25 Bqkg -1 for 40 K. Gotu kola showed the highest activity concentrations of 226 Ra and 228 Ra, while ginger showed the highest activity concentration of 40 K. The total annual effective dose due to ingestion of these herb plants were found to range from 0.0028 to 0.0097 mSvy -1 with an average value of 0.0060±0.0001 mSvy -1 . The results conclude that the Thai medicinal herb plants samples from this research are considered safe in terms of the radiological hazard. (paper)

Chinese herbal medicine (CHM) has been commonly used for treating insomnia in Asian countries for centuries. The aim of this study was to conduct a large-scale pharmaco-epidemiologic study and evaluate the frequency and patterns of CHM use in treating insomnia. We obtained the traditional Chinese medicine (TCM) outpatient claims from the National Health Insurance in Taiwan for the year 2002. Patients with insomnia were identified from the diagnostic code of International Classification of Disease among claimed visiting files. Corresponding prescription files were analyzed, and an association rule was applied to evaluate the co-prescription of CHM. Results showed that there were 16 134 subjects who visited TCM clinics for insomnia in Taiwan during 2002 and received a total of 29 801 CHM prescriptions. Subjects between 40 and 49 years of age comprised the largest number of those treated (25.3%). In addition, female subjects used CHMs for insomnia more frequently than male subjects (female : male = 1.94 : 1). There was an average of 4.8 items prescribed in the form of either an individual Chinese herb or formula in a single CHM prescription for insomnia. Shou-wu-teng (Polygonum multiflorum) was the most commonly prescribed single Chinese herb, while Suan-zao-ren-tang was the most commonly prescribed Chinese herbal formula. According to the association rule, the most commonly prescribed CHM drug combination was Suan-zao-ren-tang plus Long-dan-xie-gan-tang, while the most commonly prescribed triple drug combination was Suan-zao-ren-tang, Albizia julibrissin, and P. multiflorum. Nevertheless, further clinical trials are needed to evaluate the efficacy and safety of these CHMs for treating insomnia. PMID:19339485

Dendrobium officinale Kimura et Migo is a traditional Chinese orchid herb that has both ornamental value and a broad range of therapeutic effects. Here, we report the first de novo assembled 1.35 Gb genome sequences for D. officinale by combining the second-generation Illumina Hiseq 2000 and third-generation PacBio sequencing technologies. We found that orchids have a complete inflorescence gene set and have some specific inflorescence genes. We observed gene expansion in gene families related to fungus symbiosis and drought resistance. We analyzed biosynthesis pathways of medicinal components of D. officinale and found extensive duplication of SPS and SuSy genes, which are related to polysaccharide generation, and that the pathway of D. officinale alkaloid synthesis could be extended to generate 16-epivellosimine. The D. officinale genome assembly demonstrates a new approach to deciphering large complex genomes and, as an important orchid species and a traditional Chinese medicine, the D. officinale genome will facilitate future research on the evolution of orchid plants, as well as the study of medicinal components and potential genetic breeding of the dendrobe.

Medicinal diets have a history of more than 2000 years. Locally referred to as yaoshan (Chinese: ), a medicinal diet is understood in China as a dietary product that combines herbs and food with the purpose of preventing and treating diseases or improving health under the guidance of traditional Chinese medicine theory. Medicinal diets are used in Chinese people's daily life and in specialized restaurants. Hundreds of Chinese materia medica (CMM) are used in medicinal diets; however, a comprehensive evaluation of medicinal diets is lacking. This is an exploratory study that aims to identify the CMM that are most frequently used in medicinal diets and to provide an updated view of the current situation of medicinal diets in China. A field study of 1221 people in 32 Chinese provinces was conducted over a period of approximately 6 months and included various types of interviews as well as a written questionnaire. Two approaches were used to analyse the data collected in the survey: (1) estimating the frequency of CMM consumed in daily diets; and (2) collecting CMM used in medicinal diet restaurants. Complementary information on the selected CMM was obtained from relevant databases, including PubMed, Google Scholar, Baidu Scholar, CNKI, and Web of Science. Ten CMM were reported as commonly used by more than 50% of the participants. Among these 10 species, most medicinally used parts were seeds and fruits. Pharmacological data from the literature revealed that these species are associated with a wide spectrum of biological properties, including antitumour (80%), antioxidant (50%), anti-diabetic (40%), antilipemic (40%), anti-aging (40%), antimicrobial (40%) and cardioprotective (40%) activities. Our survey shows that most medicinal diet restaurants are located in the eastern part of China, with the greatest numbers being found in Beijing and Guangzhou. Only Dioscoreae Rhizoma, Lycii Fructus, Chrysanthemi Flos and Longan Arillus were frequently consumed both in daily

Traditional Chinese Medicine (TCM) has been widely used as a complementary medicine in Acute Myeloid Leukemia (AML) treatment. In this study, we proposed a new classification of Chinese Medicines (CMs) by integrating the latest discoveries in disease molecular mechanisms and traditional medicine theory. We screened out a set of chemical compounds on basis of AML differential expression genes and chemical-protein interactions and then mapped them to Traditional Chinese Medicine Integrated Database. 415 CMs contain those compounds and they were categorized into 8 groups according to the Traditional Chinese Pharmacology. Pathway analysis and synthetic lethality gene pairs were applied to analyze the dissimilarity, generality and intergroup relations of different groups. We defined hub CM pairs and alternative CM groups based on the analysis result and finally proposed a formula to form an effective anti-AML prescription which combined the hub CM pairs with alternative CMs according to patients' molecular features. Our method of formulating CMs based on patients' stratification provides novel insights into the new usage of conventional CMs and will promote TCM modernization.

Drug utilization studies are important for the optimization of drug therapy and have received a great attention in recent years. Most of the information on drug use patterns has been derived from studies in modern Western medicines; however, studies regarding the drug utilization of traditional Chinese medicine (CM) are few. The present study was the first clinical research to evaluate the drug utilization patterns of Chinese herbal medicines in a general hospital in Taiwan. Data were collected prospectively from the patients attending the Traditional Medicine Center of Taipei Veteran General Hospital under CM drug treatments. The study was carried out over a period of 1 year, from January 2002 to December 2002. Core drug use indicators, such as the average number of drugs per prescriptions, the dosing frequency of prescriptions, and the most common prescribed CM herbs and formulae were evaluated. The primary diagnosis and the CM drugs prescribed for were also revealed. All data were analyzed by descriptive statistics. A total of 10 737 patients, representing 52 255 CM drugs, were screened during the study period. Regarding the prescriptions, the average number of drugs per prescription was 4.87 and 37.21% of prescriptions were composed by five drugs. Most of prescriptions (91.38%) were prescribed for three times a day. The most often prescribed Chinese herb was Hong-Hwa (5.76%) and the most common Chinese herbal formula was Jia-Wey-Shiau-Yau-San (3.80%). The most frequent main diagnosis was insomnia (15.58%), followed by menopause (5.22%) and constipation (5.09%). The survey revealed the drug use pattern of CMs in a general hospital. The majority of CM prescriptions were composed by 3-6 drugs and often prescribed for three times a day. Generally, the rational drug uses of CM drugs were provided with respect to the various diagnoses. (c) 2005 John Wiley & Sons, Ltd.

2014-10-01

Full Text Available Identified as a treasure of natural herbal products, traditional Chinese medicine (TCM has attracted extensive attention for their moderate treatment effect and lower side effect. Cardio-cerebrovascular diseases (CCVD are a leading cause of death. TCM is used in China to prevent and treat CCVD. However, the complexity of TCM poses challenges in understanding the mechanisms of herbs at a systems-level, thus hampering the modernization and globalization of TCM. A novel model, termed traditional Chinese medicine systems pharmacology (TCMSP analysis platform, which relies on the theory of systems pharmacology and integrates absorption, distribution, metabolism, excretion and toxicity (ADME/T evaluation, target prediction and network/pathway analysis, was proposed to address these problems. Here, we review the development of systems pharmacology, the TCMSP approach and its applications in the investigations of CCVD and compare it with other methods. TCMSP assists in uncovering the mechanisms of action of herbal formulas used in treating CCVD. It can also be applied in ascertaining the different syndrome patterns of coronary artery disease, decoding the multi-scale mechanisms of herbs, and in understanding the mechanisms of herbal synergism.

Full Text Available Chinese herbal medicine (CHM has been commonly used for treating insomnia in Asian countries for centuries. The aim of this study was to conduct a large-scale pharmaco-epidemiologic study and evaluate the frequency and patterns of CHM use in treating insomnia. We obtained the traditional Chinese medicine (TCM outpatient claims from the National Health Insurance in Taiwan for the year 2002. Patients with insomnia were identified from the diagnostic code of International Classification of Disease among claimed visiting files. Corresponding prescription files were analyzed, and an association rule was applied to evaluate the co-prescription of CHM. Results showed that there were 16 134 subjects who visited TCM clinics for insomnia in Taiwan during 2002 and received a total of 29 801 CHM prescriptions. Subjects between 40 and 49 years of age comprised the largest number of those treated (25.3%. In addition, female subjects used CHMs for insomnia more frequently than male subjects (female : male = 1.94 : 1. There was an average of 4.8 items prescribed in the form of either an individual Chinese herb or formula in a single CHM prescription for insomnia. Shou-wu-teng (Polygonum multiflorum was the most commonly prescribed single Chinese herb, while Suan-zao-ren-tang was the most commonly prescribed Chinese herbal formula. According to the association rule, the most commonly prescribed CHM drug combination was Suan-zao-ren-tang plus Long-dan-xie-gan-tang, while the most commonly prescribed triple drug combination was Suan-zao-ren-tang, Albizia julibrissin, and P. multiflorum. Nevertheless, further clinical trials are needed to evaluate the efficacy and safety of these CHMs for treating insomnia.

Xue Charlie

2011-05-01

Full Text Available Abstract Poor quality control of medicinal herbs has led to instances of toxicity, poisoning and even deaths. The fundamental step in quality control of herbal medicine is accurate identification of herbs. Array-based techniques have recently been adapted to authenticate or identify herbal plants. This article reviews the current array-based techniques, eg oligonucleotides microarrays, gene-based probe microarrays, Suppression Subtractive Hybridization (SSH-based arrays, Diversity Array Technology (DArT and Subtracted Diversity Array (SDA. We further compare these techniques according to important parameters such as markers, polymorphism rates, restriction enzymes and sample type. The applicability of the array-based methods for fingerprinting depends on the availability of genomics and genetics of the species to be fingerprinted. For the species with few genome sequence information but high polymorphism rates, SDA techniques are particularly recommended because they require less labour and lower material cost.

Chinese herbal products (CHPs) are commonly used in patients with hyperlipidemia in traditional Chinese medicine (TCM). Because hyperlipidemia and related disease are common issues worldwide, this study analyzed the prescription patterns and frequencies of CHPs for treating patients with hyperlipidemia in Taiwan. Traditional Chinese medicine (TCM) has become popular as a therapy for controlling symptoms in patients with hyperlipidemia. This study aimed to analyze the prescription patterns of TCM for patients with hyperlipidemia in Taiwan. The study population was recruited from a random-sampled cohort of 1,000,000 people from the National Health Insurance Research Database between 2003 and 2009. We identified 30,784 outpatient visits related with hyperlipidemia diagnosis and collected these medical records. Association rules of data mining were conducted to explore the co-prescription patterns for Chinese herbal products (CHPs). The most commonly prescribed herbal formula for hyperlipidemia treatment was Xue-Fu-Zhu-Yu-Tang (16.1%), and Shan Zha (Crataegi fructus; 25.0%) was the most commonly prescribed single herb. The most commonly prescribed combination of an herbal formula and a single herb was Xue-Fu-Zhu-Yu-Tang and Dan Shen (Radix Salviae Miltiorrhizae), and the most commonly prescribed combination of couplet herbs was Dan Shen and Shan Zha. Xue-Fu-Zhu-Yu-Tang is the most frequently prescribed formula and is typically prescribed with Shan Zha, Dan Shen, and He Shou Wu for patients with hyperlipidemia. Clinical trials are warranted in future research to investigate the effects of the CHPs in terms of safety and efficacy and in particular to evaluate potential interactions with conventional treatments.

The adverse reactions caused by Chinese herbal medicine and traditional Chinese medicine are reported increased in recent years, among which the acute liver injury caused by Chinese herbal medicine accounts for 21.5% of total liver injuries. Despite the misuse of traditional Chinese medicine not in accordance with differentiation of symptoms and signs, the adverse reaction of Chinese herbal medicine itself can't be little to these adverse events. The paper summarizes the most common categories of traditional Chinese medicine resulting in liver injury, the mechanism, pathological characteristics, clinical symptom of liver injury, the reasons of the reaction and how to prevent. The research aims to enhance the clinical physician recognition of liver injury caused by Chinese herbal medicine, in order to ensure the safe and rational usage of traditional Chinese medicine.

A Single Case of Tourette’s Syndrome Treated with Traditional Chinese Medicine

Full Text Available The objective of this case study was to investigate the effectiveness of Chinese medicine in treating Tourette's syndrome. Tourette's syndrome is a childhood- onset disorder that is characterized by sudden, involuntary movements or tics. The participant in this study was a 33-year-old male who had been diagnosed with Tourette's syndrome at the age of 9 years. His major complaints included facial tics, shoulder shrugging, and clearing the throat. Using a combination of acupuncture, herbs, Gua-Sha, and lifestyle changes once a week for 35 treatments, all the symptoms were reduced by 70%, as reported by the patient. In this case, the results indicated that Chinese medicine was able to minimize the symptoms of Tourette's syndrome. Further investigation is needed to support this argument. Tourette's syndrome, which was first described in 1885 by a French physician named Gilles de la Tourette, is characterized by facial tics, involuntary body movements from the head to the extremities, or vocal tics, and it usually has its onset in childhood. It is a neuropsychiatric disorder. The treatment for Tourette's syndrome is based on pharmacological treatment, behavior treatment, and deep brain stimulation. Unfortunately, none of these could completely control the symptoms; furthermore, antipsychiatric drugs might cause additional side effects, such as Parkinson symptoms, tardive dyskinesia, and metabolic disturbances. Finding acupuncture and oriental medicine literature on treatment of Tourette's syndrome was difficult, especially that written in English. Some research papers that have been translated into English indicated that Chinese herbs and acupuncture could reduce the tics significantly. For example, a study by Dr Pao-Hua Lin reported the significant effects of using acupuncture and oriental medicine in treating 1000 Tourette's syndrome cases. This case was treated to further investigate the principles of Dr Lin's study.

Lifting and lowering theory is one of the important basis for guiding clinical medication. Through the study of ancient books and literature, we learned that lifting and lowering theory was originated in Huangdi Neijing, practiced more in the Shanghan Zabing Lun, established in Yixue Qiyuan, and developed in Compendium of Materia Medica and now. However, lifting and lowering theory is now mostly stagnated in the theoretical stage, with few experimental research. In the clinical study, the guiding role of lifting and lowering theory to prescriptions?mainly includes opposite?role?of lift and lower medicine property, mutual promotion of lift and lower medicine property, main role of lift medicine property and main role of lower medicine property. Under the guidance of lifting and lowering theory, the herb pair compatibility include herb combination of lift medicine property, herb combination of lift and lower medicine property and herb combination of lower medicine property. Modern biological technology was used in this study to carry out experimental research on the lifting and lowering theory, revealing the scientific connotation of it, which will help to promote clinical rational drug use.

Medicinal herbs have been increasingly used for therapeutic purposes against a diverse range of human diseases worldwide. Moreover, the health benefits of spices have been extensively recognized in recent studies. However, inevitable contaminants, including mycotoxins, in medicinal herbs and spices can cause serious problems for humans in spite of their health benefits. Along with the different nation-based occurrences of mycotoxins, the ultimate exposure and toxicities can be diversely influenced by the endogenous food components in different commodities of the medicinal herbs and spices. The phytochemicals in these food stuffs can influence mold growth, mycotoxin production and biological action of the mycotoxins in exposed crops, as well as in animal and human bodies. The present review focuses on the occurrence of mycotoxins in medicinal herbs and spices and the biological interaction between mold, mycotoxin and herbal components. These networks will provide insights into the methods of mycotoxin reduction and toxicological risk assessment of mycotoxin-contaminated medicinal food components in the environment and biological organisms.

For ages, herbs have been used as medicine and food. Nowadays, the interest in phytotherapeutics is increasing as well as the consumer attention. Some biochemical compounds synthesized by plants as alkaloids, phenolics, flavonoids, essential oils, tannins and vitamins, influence the composition of these plant pharmacologicals, which may produce various reactions in the human body. The microbial contamination in these raw plant materials is common, and the radiation processing is one appropriate technique for the reduction of microorganism. In herbs used as food products, the changes in total β-carotene and flavonoids upon the radiation treatment were tested. The powdered and dehydrated herbs were irradiated with 60 Co gamma rays applying doses of 0, 10, 20 and 30 kGy. The botanical species investigated were rosemary (Rosmarinus officinalis Linne), watercress (Nasturtium officinale R. Br), artichoke (Cynara scolymus Linne) and sweet basil (Ocimum basilicum Linne). The alterations in the active principles in the herbs following increasing doses of radiation were analyzed employing various methods of extraction and chromatography

Full Text Available Accumulating epidemiological and clinical evidence shows that inflammation is an important risk factor for various human diseases. Thus, suppressing chronic inflammation has the potential to delay, prevent, and control various chronic diseases, including cerebrovascular, cardiovascular, joint, skin, pulmonary, blood, lymph, liver, pancreatic, and intestinal diseases. Various natural products from traditional Chinese medicine (TCM have been shown to safely suppress proinflammatory pathways and control inflammation-associated disease. In vivo and/or in vitro studies have demonstrated that anti-inflammatory effects of TCM occur by inhibition of the expression of master transcription factors (for example, nuclear factor-κB (NF-κB, pro-inflammatory cytokines (for example, tumor necrosis factor-α (TNF-α, chemokines (for example, chemokine (C-C motif ligand (CCL-24, intercellular adhesion molecule expression and pro-inflammatory mediators (for example, inducible nitric oxide synthase (iNOS and cyclooxygenase 2 (COX2. However, a handful of review articles have focused on the anti-inflammatory activities of TCM and explore their possible mechanisms of action. In this review, we summarize recent research attempting to identify the anti-inflammatory constituents of TCM and their molecular targets that may create new opportunities for innovation in modern pharmacology.

Constipation is a common gastrointestinal problem worldwide. The aim of this study was to determine the frequency of use and prescriptive patterns of Chinese herbal medicine (CHM) in treating constipation by analyzing the claims data of traditional Chinese medicine (TCM) from the National Health Insurance (NHI) in Taiwan. The computerized claims dataset of the TCM office visits and the corresponding prescription files in 2004 compiled by the NHI Research Institute in Taiwan were linked and processed. Visit files with the single diagnostic coding of constipation (ICD-9-CM code 564.0) were extracted to analyze the frequency and pattern of corresponding CHM prescriptions. The association rule was applied to analyze the co-prescription of CHM in treating constipation. There were 152,564 subjects who visited TCM clinics only for constipation in Taiwan during 2004 and received a total of 387,268 CHM prescriptions. Subjects between 20 and 29 years of age comprised the largest number of those treated (25.5%). Female subjects used CHM for constipation more frequently than male subjects (female:male = 3.31:1). There was an average of 4.6 items of single Chinese herbs or formula in a single prescription for constipation. Ma-zi-renwan was the most commonly prescribed herbal formula, while Da-huang (Rheum palmatum) was the most commonly used single Chinese herb. According to the association rule, the most common prescribed pattern of 2-drug combination of CHM for treating constipation was Ban-xia-xie-xin-tang plus Ma-zi-ren-wan, while the 3-drug combination of CHM was Fang-feng-tong-sheng-san, Rheum palmatum and Ma-zi-ren-wan. This study showed the pattern of single Chinese herbs or herbal formulae used in treating constipation in Taiwan.

Traditional Chinese medicines (TCMs) have a long history for safely treating human diseases. Unlike western medicine, TCMs usually contain multiple components synergistically and holistically acting on the diseases. It remains a big challenge to represent rationally the in vivo process of multiple components of TCMs for understanding the relationship between administration and therapeutic effects. For years, efforts were always made to face the challenge, and the achievements were obvious. Here, we give an comprehensive overview of the recent investigation progress (from 2015 to 2017, except the part of 'integrated pharmacokinetics of TCMs' from 2014 to 2017 and the part of 'reverse pharmacokinetics in drug discovery from natural medicines' in 2014) on pharmacokinetics of TCMs, mainly referring to the following six aspects: (1) classical pharmacokinetic studies on TCMs; (2) absorbed components and metabolites identification of TCMs; (3) pharmacokinetic herb-drug interactions and herb-herb interactions with TCMs; (4) integrated pharmacokinetics of TCMs; (5) pharmacokinetic and pharmacodynamic combination studies to dissect the action mechanisms of TCMs; and (6) reverse pharmacokinetics in drug discovery from natural medicines. Finally, based on the insights from the recent progress and our latest efforts, we propose new perspectives on the integrated pharmacokinetics of TCMs.

A few factors such as age, stress, and emotions may lead to impaired learning, memory loss, amnesia, and dementia or threats like schizophrenia and Alzheimer's disease (AD). Iranian traditional medicine (ITM) recommends some herbs and herbal preparations for the treatment or prevention of CNS problems. In this study, scientific evidence related to the effectiveness of ITM herbal medicine on memory, learning and AD is reviewed. The scientific evidence of plant efficacy was searched in electronic databases including PubMed, Scopus, SID, Science Direct, and Google Scholar by keywords such as memory, Alzheimer, amnesia, learning and scientific plant names from 1969 to 2014. The findings of this study confirmed the effectiveness of certain ITM medicinal plants on enhancing memory and learning or in the treatment/prevention of amnesia and AD. Some ITM plants like Melissa officinalis, Crocus sativus and Nigella sativa showed improving effects on memory and the treatment of AD in clinical trials. In some cases, active principles responsible for the efficacy of these plants on memory were also determined. Most of the studies on ITM plants were designed in animal models and a few herbs were evaluated in clinical trials on AD. Furthermore, there are insufficient or no investigations on certain herbal medicines used in ITM to confirm their effectiveness on memory and learning. Therefore, further experimental and clinical studies are necessary to evaluate the effectiveness of these plants on memory and AD as well as determining their active components.

Complementary and alternative therapies in treating atopic dermatitis are not uncommon. However, substantial evidence and consensus on treating atopic dermatitis is lacking. The aim of this study is to investigate the characteristics and utilization of traditional Chinese medicine in patients with atopic dermatitis. We retrospectively collected patients with atopic dermatitis at the Chang Gung Memorial Hospital in Taiwan between 2002 and 2011. Patients' demographic data, duration and frequency of treatment, serum total immunoglobulin E levels, and traditional Chinese medicine treatment principles and prescription were analyzed. There were 4145 patients (8.8%) received traditional Chinese medicine therapy between 2002 and 2011. Among them, 2841 (68.54%) chose TCM only and 1304 (31.46%) chose to combine TCM and WM therapies. Those who chose combination therapy were younger, and needed more times of visit and longer duration of treatment. The most frequent comorbid conditions accompany atopic dermatitis were allergic rhinitis (46.06%) and asthma (21.46%). Among the 87,573 prescriptions written for Chinese medicine, the most frequently prescribed herbal formula and single herb were Xiao-Feng-San (Eliminate Wind Powder) (16.98%) and Bai-Xian-Pi (Cortex Dictamni) (12.68%), respectively. The most commonly used therapeutic principles of herbal formulas and single herbs were releasing exterior (20.23%) and clearing heat (41.93%), respectively. Our hospital-based study characterized the utilization patterns of traditional Chinese medicine in atopic dermatitis patients. This information could be used as references for clinical application and provide valuable information for future clinical trials. Copyright © 2013 Elsevier Ltd. All rights reserved.

For most complementary and alternative medicine interventions, the absence of a high-quality evidence base to define good practice presents a serious problem for clinicians, educators, and researchers. The Delphi process may offer a pragmatic way to establish good practice guidelines until more rigorous forms of assessment can be undertaken. To use a modified Delphi to develop good practice guidelines for a feasibility study exploring the role of Chinese herbal medicine (CHM) in the treatment of endometriosis. To compare the outcomes from Delphi with data derived from a systematic review of the Chinese language database. An expert group was convened for a three-round Delphi that initially produced key statements relating to the CHM diagnosis and treatment of endometriosis (round 1) and then anonymously rated these on a 1-7 Likert scale (rounds 2 and 3). Statements with a median score of 5 and above were regarded as demonstrating positive group consensus. The differential diagnoses within Chinese Medicine and rating of the clinical value of individual herbs were then contrasted with comparable data from a review of Chinese language reports in the Chinese Biomedical Retrieval System (1978-2002), and China Academy of Traditional Chinese Medicine (1985-2002) databases and the Chinese TCM and magazine literature (1984-2004) databases. Consensus (good practice) guidelines for the CHM treatment of endometriosis relating to common diagnostic patterns, herb selection, dosage, and patient management were produced. The Delphi guidelines demonstrated a high degree of congruence with the information from the Chinese language databases. In the absence of rigorous evidence, Delphi offers a way to synthesize expert knowledge relating to diagnosis, patient management, and herbal selection in the treatment of endometriosis. The limitations of the expert group and the inability of Delphi to capture the subtle nuances of individualized clinical decision-making limit the usefulness of

Glucosinolates were evaluated in 19 traditional Chinese medicinal plants involved in seven different families: Brassicaceae, Capparaceae, Euphorbiaceae, Phytolaccaceae, Tropaeolaceae, Caricaceae and Rubiaceae. The total glucosinolate contents were determined by spectrophotometry. Results showed that the high contents of total glucosinolates were found in some herbs of Brassicaceae, Capparaceae and Euphorbiaceae families, while low total glucosinolate contents were observed in two Rubiaceae herbs. In addition, eight glucosinolates (glucoraphanin, glucoraphenin, sinalbin, sinigrin, progoitrin, 4-hydroglucobrassicin, glucoiberin and glucoibervirin) in these herbs were measured using HPLC, and the data showed that individual glucosinolates and their contents varied at different degrees among the distinct species. The highest contents of cancer-protective compounds were found in the seeds of Raphanus sativus L. (glucoraphenin), Sinapis alba (sinalbin) and Phyllanthus emblica L. (sinigrin).

For ages, herbs have been used as medicine and food. Nowadays, the interest in phytotherapeutics is increasing as well as the consumer attention. Some biochemical compounds synthesized by plants as alkaloids, phenolics, flavonoids, essential oils, tannins and vitamins, influence the composition of these plant pharmacologicals, which may produce various reactions in the human body. The microbial contamination in these raw plant materials is common, and the radiation processing is one appropriate technique for the reduction of microorganism. In herbs used as food products, the changes in total β-carotene and flavonoids upon the radiation treatment were tested. The powdered and dehydrated herbs were irradiated with 60Co gamma rays applying doses of 0, 10, 20 and 30 kGy. The botanical species investigated were rosemary ( Rosmarinus officinalis Linné), watercress ( Nasturtium officinale R. Br), artichoke ( Cynara scolymus Linné) and sweet basil ( Ocimum basilicum Linné). The alterations in the active principles in the herbs following increasing doses of radiation were analyzed employing various methods of extraction and chromatography.

INTRODUCTION: In a country dominated by western healthcare, interest in traditional Chinese medicine (TCM) is growing. The increasing popularity of TCM, occasionally used with conventional medicine, needs to be assessed, especially in a vulnerable paediatric population. This paper sought to evaluate the use of TCM in children, mainly to determine the common conditions they seek TCM, the pattern of acupuncture or herbal usage for various age groups, the extent of concurrent usage of TCM and conventional medicine, and the reasons for TCM use. Paediatricians\\' perceptions of TCM will allow us to gauge the acceptability of TCM by those who practise conventional medicine. These are assessed in another arm of this study, with a set of predictive characteristics for their personal TCM use, their perceptions of herb\\/acupuncture safety, and their own referral to TCM eventually determined. METHODS: An anonymous questionnaire was administered on 300 parents awaiting consultation at a large TCM clinic. Next, a separate qualitative questionnaire survey form was posted to 100 paediatricians. RESULTS: Herb usage in children is very common (84.3 percent) and 80 percent of parents admitted concurrent usage of TCM and conventional medicine for their children. Drug-herb interactions was an issue of concern for paediatricians. Paediatricians with a higher level of self-reported TCM knowledge were more likely to refer for a cure. CONCLUSION: This was the first study to determine the characteristics of children attending a large TCM clinic in a country which is dominated by western healthcare. It also provided insight into the perceptions of TCM among paediatricians in Singapore. Specifically, it gave us an idea of the predictor traits that determine their referral patterns to TCM and their perceptions of herb and acupuncture safety.

Herb medicines are traditional medicine in Japan and have been used for medical treatment. These herb medicines are contaminating frequently by microorganisms which has possibility to cause opportunistic diseases. Recently, hygienic standard of herb medicines become more strict than before, and it needs to decontaminate microorganisms by some treatments. However, chemical treatments such as by ethylene oxide fumigation leave toxic residues in the herbs while steam sterilization decease medicinal components. From study on the distribution of microorganisms in 31 samples of selected herb medicines, colony forming units of total aerobic bacteria were determined to be l.9 x 10 2 to l.4 x 10 8 per gram in 30 samples. Coliforms were also determined to be 6.9 x 10 2 to 4.3 x 10 6 per gram in 16 samples. The main aerobic bacteria were identified as Bacillus pumilus, B. circulans, B. megaterium, Erwinia, Enterobacter and Acinetobacter, whereas consisted mainly of Enterobacter in coliform counts. Molds were determined to be 6.3 x 10 1 to 1.9 x 10 5 per gram which consisted mainly Aspergillus glaucus group, A. restrictus group, A. flavus group, A. ostianus, A. phoenicis, Penicillium, Tricoderma, Rhizopus and Alternaria in 25 samples. A study on the inactivation of microorganisms at sample No. S18 showed that a gamma-irradiation dose of 20 kGy was required to reduce the total aerobic bacteria and the coliforms below a detectable level, while radiation-resistant bacteria were survived at high doses more than 10 kGy consisted with Acinetobacter and Enterobacter. Molds were inactivated below 8 kGy except Alternaria. However, a dose of 10 kGy should be effective for the sample No. S18 to reduce the spore-forming bacteria, the fecal coliforms and the molds below a detectable level per gram. On the study of inactivation of microorganisms in many samples except the No. 18, all kinds of microorganism were inactivated below a detectable level at 10 kGy irradiation. (author)

Today, herb medicines have become the major source for discovery of novel agents in countermining diseases. However, many of them are largely under-explored in pharmacology due to the limitation of current experimental approaches. Therefore, we proposed a computational framework in this study for network understanding of herb pharmacology via rapid identification of putative ingredient-target interactions in human structural proteome level. A marketing anti-cancer herb medicine in China, Yadanzi (Brucea javanica), was chosen for mechanistic study. Total 7,119 ingredient-target interactions were identified for thirteen Yadanzi active ingredients. Among them, about 29.5% were estimated to have better binding affinity than their corresponding marketing drug-target interactions. Further Bioinformatics analyses suggest that simultaneous manipulation of multiple proteins in the MAPK signaling pathway and the phosphorylation process of anti-apoptosis may largely answer for Yadanzi against non-small cell lung cancers. In summary, our strategy provides an efficient however economic solution for systematic understanding of herbs' power.

Patients with a polyherbal prescription are more likely to receive duplicate medications and thus suffer from adverse drug reactions. We conducted a population-based retrospective study to examine the items of Chinese herbal medicine (CHM) per prescription in the ambulatory care of traditional Chinese medicine (TCM) in Taiwan. We retrieved complete TCM ambulatory visit datasets for 2010 from the National Health Insurance database in Taiwan. A total of 59,790 patients who received 313,482 CHM prescriptions were analyzed. Drug prescriptions containing more than five drugs were classified as polyherbal prescriptions; 41.6% of patients were given a polyherbal prescription. There were on average 5.2 ± 2.5 CHMs: 2.3 ± 1.1 compound herbal formula items, and 3.0 ± 2.5 single Chinese herb items in a single prescription. Approximately 4.6% of patients were prescribed 10 CHMs or more. Men had a lower odds ratio (OR) among polyherbal prescriptions (OR = 0.96, 95% confidence interval [CI] 0.92–0.99), and middle-aged patients (35–49 years) had the highest frequency of polyherbal prescription (OR = 1.19, 95% CI = 1.13–1.26). Patients with neoplasm, skin and subcutaneous tissue disease, or genitourinary system disease were more likely to have a polyherbal prescription; OR = 2.20 (1.81–2.67), 1.65 (1.50–1.80), and 1.52 (1.40–1.64), respectively. Polyherbal prescription is widespread in TCM in Taiwan. Potential herb interactions and iatrogenic risks associated with polyherbal prescriptions should be monitored. PMID:26287228

Effects of processing adjuvants on traditional Chinese herbs

2018-04-01

Full Text Available Processing of Chinese medicines is a pharmaceutical technique that transforms medicinal raw materials into decoction pieces for use in different therapies. Various adjuvants, such as vinegar, wine, honey, and brine, are used in the processing to enhance the efficacy and reduce the toxicity of crude drugs. Proper processing is essential to ensure the quality and safety of traditional Chinese medicines (TCMs. Therefore, sound knowledge of processing principles is crucial to the standardized use of these processing adjuvants and to facilitate the production and clinical use of decoction pieces. Many scientific reports have indicated the synergistic effects of processing mechanisms on the chemistry, pharmacology, and pharmacokinetics of the active ingredients in TCMs. Under certain conditions, adjuvants change the content of active or toxic components in drugs by chemical or physical transformation, increase or decrease drug dissolution, exert their own pharmacological effects, or alter drug pharmacokinetics. This review summarizes various processing methods adopted in the last two decades, and highlights current approaches to identify the effects of processing parameters on TCMs. Keywords: Adjuvant, Processing, Synergism, Traditional Chinese medicine

BACKGROUND This randomized, controlled trial was designed to assess whether acupuncture plus an oral administration of Chinese herbal medicine provides greater relief of symptoms than oral administration of Chinese herbal medicine alone for treatment of pelvic inflammatory sequelae. MATERIAL AND METHODS Sixty-two patients ages 22 to 45 years with pelvic inflammatory sequelae were randomly assigned into one of 2 groups: an herbal group (n=30) and an herbal with acupuncture group (n=32). Both groups were treated for 3 courses of 3 months each. RESULTS Significant improvement of clinical symptoms and signs of pelvic inflammatory sequelae occurred in both treatment groups. The total effective rate for the herbal group was 83.33%, and for the herbal with acupuncture group it was 100% ([i]P[/i]=0.354 for difference between groups). During treatment, 5 patients had adverse reactions of nausea, loss of appetite, and diarrhea. After adjustment of the herb prescription, all adverse reactions disappeared. CONCLUSIONS Our results highlight the benefit of oral administration of Chinese herbal medicine along with acupuncture; this had a greater clinical curative effect rate than oral administration of Chinese herbal medicine alone when treating pelvic inflammatory sequelae.

Aristolochic acid-associated nephropathy (AAN) has been identified as a separate entity of progressive tubulo-interstitial nephropathy. Its characteristic pathological findings, including hypocellular interstitial fibrosis, intimal thickening of interlobular and afferent arterioles with glomeruli sparing or mild sclerosis, have been identified. Many cases of AAN in adults have been reported in Taiwan as well as throughout the world, but it has seldom been described in children. We report on a 10-year-old boy who presented with severe anemia, Fanconi's syndrome, and progressive renal failure. Renal biopsy revealed typical findings of AAN. Aristolochic acids I and II were identified from a Chinese herb mixture ingested by the boy. AAN was diagnosed after other etiologies had been excluded. The case demonstrates the hazards of Chinese herbs with regard to children's health in Taiwan and suggests that more attention should be paid to this issue.

Allergic rhinitis (AR) is a common allergic disorder in children, some of whom seek complementary treatments, including acupuncture and Chinese herbs. Little, however, is known about the treatment of pediatric AR with traditional Chinese medicine (TCM). To characterize TCM use in pediatric AR, we conducted a nationwide population-based study. We screened one million randomly sampled beneficiaries of the National Health Insurance Program in Taiwan from 2002 to 2010 to identify children herb was Chan-Tui (Periostracum cicadae; 13.78%). Regarding syndrome differentiation (ZHENG) according to TCM theory, prescriptions for the Cold Syndrome exceeded those for the Hot Syndrome throughout the year in Taiwan. We found that approximately two-thirds of pediatric AR patients were prescribed TCM treatments in Taiwan. Further research is warranted to examine the efficacy and safety of TCM for pediatric AR patients. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

For thousands of years, the natural resource for Chinese materiamedica has been the foundation of the traditional Chinese medicine industry, which provides abundant medicine for human. In recent years, increasing demands and irrational exploitation led to a lot of problems such as rapid decrease of traditional Chinese herbs reserves, low quality of medicine and dismishing traditional cultures. These restricted the development of the traditional Chinese medicine. To solve these problems, scientists have done much work on investigating traditional Chinese medicine resources, exploring the metabolic pathway of bioactive ingredients, cultivating new varieties, and carrying out synthetic biology. These studies provided a theoretical basis for sustainable utilizationand future developmentof traditional Chinese medicine resources.

Modern medicine often clashes with traditional medicine such as Chinese herbal medicine because of the little understanding of the underlying mechanisms of action of the herbs. In an effort to promote integration of both sides and to accelerate the drug discovery from herbal medicines, an efficient systems pharmacology platform that represents ideal information convergence of pharmacochemistry, ADME properties, drug-likeness, drug targets, associated diseases and interaction networks, are urgently needed. The traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) was built based on the framework of systems pharmacology for herbal medicines. It consists of all the 499 Chinese herbs registered in the Chinese pharmacopoeia with 29,384 ingredients, 3,311 targets and 837 associated diseases. Twelve important ADME-related properties like human oral bioavailability, half-life, drug-likeness, Caco-2 permeability, blood-brain barrier and Lipinski's rule of five are provided for drug screening and evaluation. TCMSP also provides drug targets and diseases of each active compound, which can automatically establish the compound-target and target-disease networks that let users view and analyze the drug action mechanisms. It is designed to fuel the development of herbal medicines and to promote integration of modern medicine and traditional medicine for drug discovery and development. The particular strengths of TCMSP are the composition of the large number of herbal entries, and the ability to identify drug-target networks and drug-disease networks, which will help revealing the mechanisms of action of Chinese herbs, uncovering the nature of TCM theory and developing new herb-oriented drugs. TCMSP is freely available at http://sm.nwsuaf.edu.cn/lsp/tcmsp.php.

Allergic rhinitis has long been a worldwide health problem with a global growth trend. The use of traditional Chinese medicines alone or integrated Chinese-Western medicines for its treatment is quite common in Taiwan. Respiratory diseases account for the majority of outpatient traditional Chinese medicine treatment, while allergic rhinitis accounts for the majority of respiratory diseases. We hereby conduct a comparative analysis between traditional Chinese medicine treatments and western medicine treatments for allergic rhinitis in Taiwan. The results of the analysis on the prescription difference of traditional Chinese medicine and western medicine treatments would be helpful to clinical guide and health policy decision making of ethnopharmacological therapy. Patients diagnosed as allergic rhinitis with diagnostic code 470-478 (ICD-9-CM) were selected as subjects from 2009-2010 National Health Insurance Research Database based on the claim data from the nationwide National Health Insurance in Taiwan. This retrospective study used Chi-Square test to test the effects of gender and age on visit of traditional Chinese medicine, western medicine, and integrated Chinese-Western medicine treatments. A total of 45,804 patients diagnosed as allergic rhinitis with ICD-9-CM 470-478 were identified from 2009-2010 NHIRD. There were 36,874 subjects for western medicine treatment alone, 5829 subjects for traditional Chinese medicine treatment alone, and 3101 subjects for integrated Chinese-Western medicine treatment. Female patients were more than male in three treatments. 0-9 years children had the highest visit frequency in western medicine and integrated Chinese-Western medicine groups, while 10-19 years young-age rank the highest in traditional Chinese medicine group. The Chi-square test of independence showed that the effects of gender and age on visit of three treatments were significant. The prescription drugs of western medicine treatment alone were almost for

The molecular connectivity index was adopted to explore the characteristics of supramolecular imprinting template of herbs distributed to liver meridian, in order to provide scientific basis for traditional Chinese medicines(TCMs) distributed to liver meridian. In this paper, with "12th five-year plan" national planning textbooks Science of Traditional Chinese Medicine and Chemistry of Traditional Chinese Medicine as the blueprint, literatures and TCMSP sub-databases in TCM pharmacology of northwest science and technology university of agriculture and forestry were retrieved to collect and summarize active constituents of TCM distributed to liver meridian, and calculate the molecular connectivity index. The average molecular connectivity index of ingredients distributed to liver meridian was 9.47, which was close to flavonoid glycosides' (9.17±2.11) and terpenes (9.30±3.62). Therefore, it is inferred that template molecule of liver meridian is similar to physicochemical property of flavonoid glycosides and terpenes, which could be best matched with imprinting template of liver meridian.

Instrumental neutron activation analysis has been used for the analysis of seven varieties of medicinal herbs generally used by the people of South Asian region. Twenty-one trace elements (essential, toxic and non-essential) were determined. This data should not only be helpful in establishing the base-line values in these medicinal herbs but also in correlating their role as therapeutic agents. A comparison of our data with literature values shows variation in trace element contents of same species of different origin which can be attributed to ecological and geographical variations to some extent; however an exact interpretation demands further extensive investigations.

Chinese herbal medicine (CHM) has been commonly used in treating liver diseases in Asian countries. To conduct a large-scale pharmacoepidemiological study and evaluate the frequency and pattern of CHM prescriptions in treating chronic hepatitis. We obtained the database of traditional Chinese medicine outpatient claims from the national health insurance in Taiwan for the whole 2002. Patients with chronic hepatitis were identified by the corresponding diagnosis of International Classification of Disease among claimed visiting files. Corresponding prescription files were analyzed, and association rule were applied to evaluate the co-prescription of CHM in treating chronic hepatitis. Among the 91,080 subjects treated by CHM for chronic hepatitis, the peak age was in the 40 s, followed by 30 s and 50 s. Male/female ratio was 2.07:1. Long-dan-xie-gan-tang and Saliva miltiorrhiza (Dan-shen) were the most commonly prescribed Chinese herbal formula and single herbal drug, respectively. The most common two-drug prescription was Jia-wei-xia-yao-san plus Saliva miltiorrhiza, and the most common three-drug prescription was Jia-wei-xia-yao-san plus Saliva miltiorrhiza and Artemisia capillaries (Yin-chen-hao). This study showed the utilization pattern of Chinese herbal drugs or formulae in treating chronic hepatitis. Further researches and clinical trials are needed to evaluate the efficacy of these Chinese herbs or its ingredients in treating chronic hepatitis.

Background. Alternative approaches for managing depression are often sought and herbal mixtures are widely used in China. The aim of this paper was to provide an overall picture of the current evidence by analysing published systematic reviews and presenting a supplementary systematic review of trials in Western databases. Methods. Searches were conducted using AMED, Cochrane Library, EMBASE, MEDLINE/PubMed, PsycINFO, and trial registers. Results were screened and selected trials were evaluated by two reviewers working independently. Systematic reviews were identified and assessed using key criteria. Results. Five systematic reviews were located addressing the Chinese literature, adjunctive use of Chinese herbs, and the formulae Chaihu-Shugan-San, Xiao Yao San, and Free and Easy Wanderer Plus. The supplementary review located 8 trials, 3 of which were not included in previous reviews. Positive results were reported: no significant differences from medication, greater effect than medication or placebo, reduced adverse event rates when combined or compared with antidepressants. However, limitations in methodology and reporting were revealed. Conclusions. Despite promising results, particularly for Xiao Yao San and its modifications, the effectiveness of Chinese herbal medicine in depression could not be fully substantiated based on current evidence. Further well-designed, well-reported trials that reflect practice may be worth pursuing.

Heat stress negatively affects the productivity of chickens in commercial poultry farms in humid tropics. In this study, the concentrations and types of the antioxidant compounds of eight Chinese herbal medicines, which have previously demonstrated promising effects on suppressing heat stress as a mixture, were investigated using reversed-phase High Performance Liquid Chromatography, spectrophotometry, Liquid Chromatography Mass Spectrometry, and Gas-Liquid Chromatography. Our results provided the levels of phenolic compounds, total amounts of sugars, and total unsaturated fatty acids in the herbal extracts. Apart from the detection and quantification of the active ingredients of herbs that have the potential to mitigate heat stress in poultry, results of this study also provide useful data for developing an efficient and accurate formulation of the herbs' mixtures in order to induce positive effects against heat stress in in vivo studies.

Mechanisms of Anorexia Cancer Cachexia Syndrome and Potential Benefits of Traditional Medicine and Natural Herbs.

Science.gov (United States)

Ming-Hua, Cong; Bao-Hua, Zou; Lei, Yu

Anorexia cancer cachexia syndrome is prevalent in advanced cancer patients, which is featured by anorexia, decreased dietary intake, body weight loss (skeletal muscle mass loss), and is unable to be reversed by routine nutritional support therapy. Up to now, the main mechanisms involved in cancer cachexia include excessive systemic inflammation, which is represented by increased plasma levels of IL-1, IL-6, TNF-alpha, tumor-induced factors, such as PIF and LMF. These factors eventually act on orexigenic and anorexigenicneurons located in the hypothalamus or protein and lipid metabolism of peripheral tissues, which lead to anorexia, decreased dietary intake, enhanced basic metabolism rate and hypercatabolism. The treatment modality includes early nutritional intervention, physical activity and drug treatment. However, studies about drugs used to treat cachexia are always controversial or merely effective in stimulating appetite and increasing body weight, though not lean body mass. The main target of pharmaceutical treatment is to improve appetite, decrease systemic inflammation and promote anabolic metabolism. Nevertheless, the treatment effectiveness of chemical drugs are not reaching consensus by existing cachexia guidelines. Complementary and alternative medicine (CAM) is recently known as a promising treatment to improve cachaxia status and quality of life of cancer patients. Traditional Chinese medicine (TCM) and natural herbal medicines have been used in the treatment of cancer for thousands of years worldwide, particularly in China. More and more research show that traditional Hanfang (Chinese medicines) and some natural herbs with less side reactions, have the effects of antagonizing pro-inflammatory cytokines, enhancing immune system, inhibiting protein catabolism, boosting the appetite and body weight, which maybe a promising treatment strategy and development tendency for anorexia cancer cachexia syndrome.

An ionic liquid-based microwave-assisted extraction (ILMAE) method has been developed for the effective extraction of rutin from Chinese medicinal plants including Saururus chinensis (Lour.) Bail. (S. chinensis) and Flos Sophorae. A series of 1-butyl-3-methylimidazolium ionic liquids with different anions were investigated. The results indicated that the characteristics of anions have remarkable effects on the extraction efficiency of rutin and among the investigated ionic liquids, 1-butyl-3-methylimidazolium bromide ([bmim]Br) aqueous solution was the best. In addition, the ILMAE procedures for the two kinds of medicinal herbs were also optimized by means of a series of single factor experiments and an L(9) (3(4)) orthogonal design. Compared with the optimal ionic liquid-based heating extraction (ILHE), marinated extraction (ILME), ultrasonic-assisted extraction (ILUAE), the optimized approach of ILMAE gained higher extraction efficiency which is 4.879 mg/g in S. chinensis with RSD 1.33% and 171.82 mg/g in Flos Sophorae with RSD 1.47% within the shortest extraction time. Reversed phase high performance liquid chromatography (RP-HPLC) with ultraviolet detection was employed for the analysis of rutin in Chinese medicinal plants. Under the optimum conditions, the average recoveries of rutin from S. chinensis and Flos Sophorae were 101.23% and 99.62% with RSD lower than 3%, respectively. The developed approach is linear at concentrations from 42 to 252 mg L(-1) of rutin solution, with the regression coefficient (r) at 0.99917. Moreover, the extraction mechanism of ILMAE and the microstructures and chemical structures of the two researched samples before and after extraction were also investigated. With the help of LC-MS, it was future demonstrated that the two researched herbs do contain active ingredient of rutin and ionic liquids would not influence the structure of rutin.

Traditional Chinese medicine (TCM), such as Uyghur Medicine (UM) has been used in clinical treatment for many years. TCM is featured as multiple targets and complex mechanisms of action, which is normally a combination of medicinal herbs and sometimes even contains certain rare animal medicinal ingredients. A question arises as to whether these animal materials can be removed replaced from TCM applications due to their valuable rare resources or animal ethics. Here, we select a classical UM Yimusake formula, which contains 3 animal drugs and other 8 herbs, and has got wealthy experience and remarkable achievements in treating erectile dysfunction (ED) in China. The active components, drug targets and therapeutic mechanisms have been comprehensively analyzed by systems-pharmacology methods. Additionally, to validate the inhibitory effects of all candidate compounds on their related targets, in vitro experiments, computational analysis and molecular dynamics simulations were performed. The results show that the modified, original and three animal materials display very similar mechanisms for an effective treatment of ED, indicating that it is quite possible to remove these three animal drugs from the original formula while still keep its efficiency. This work provides a new attempt for deleting animal materials from TCM, which should be important for optimization of traditional medicines.

Full text: Introduction: Nowadays the interest in phytotherapeutics is increasing; therefore the consumer attention to the medicinal active plants is growing. The rich Brazilian flora, represents more than 20% of the plant species know in the world as raw materials for pharmaceutical preparations. Since the last decade microbiological decontamination of medicinal herbs by irradiation has been carried out and presented in many scientific articles. The microbial contamination in these raw plant materials is the issue of several studies, which propose appropriate techniques for the reduction of micro-organisms. One of these techniques is radiation processing by gamma source industrial plants. Other is the utilisation of accelerators. In order to safeguard consumers, treatment by ionizing radiation is allowed now in Brazil to medicinal herbs and pharmaceutical products. The radiation process is known as safe for a large variety of products and applications as well as a effective in the reduction of pathogenic micro-organisms. The aim of our study is observe if flavonoids and alkaloids will be influenced by irradiation. Experimental: Samples - Local herbs companies in Sao Paulo, Brazil, provided dehydrated samples of Rhamnus purshiana D.C. and Paulinia cupana Kunth. Irradiation. The powdered samples were irradiated in on plastic package in a electron beam accelerator facility of Radiation Dynamics Inc., USA (E=1,5 MeV, l=25 mA, installed in IPEN Sao Paulo, Brazil. The irradiation doses were 10,20 and 30 kGy at room temperature. The thickness of samples was less than 0,5 cm. Sample analysis -flavonoids and alkaloids analysis was performed in a Thin Layer Chromatography according to Wagner (1995). Results and discussion: No alterations in the flavonoids and alkaloids, after irradiation treatment in that herbs was observed. Chromatographic analysis of the different extracts irradiated at increasing doses indicated that there were no great differences in the chemical

To observe the clinical efficiency and safety of Benazepril and wind dispelling and dampness removing Chinese herbs were singly or combined used in patients with stage 3 chronic kidney disease (CKD 3), and to provide effective integrative medicine methods for treatment of CKD 3. The CKD 3 was allocated to qi and yin deficiency syndrome, inner disturbance of wind and damp syndrome, stasis in Shen meridian syndrome, and inner accumulation of damp and heat syndrome. Recruited were patients of inner disturbance of wind and damp syndrome accompanied or unaccompanied with the other 3 syndrome types. In the prospective, randomized, double blind controlled study, 60 patients confirmed as primary chronic glomerulonephritis (CGN) were randomly assigned to 3 groups with a total course of treatment for 24 weeks. Patients in the Western medicine group (WM, 23 cases) took Benazepril (10 mg/d). Those in the Chinese medicine group (CM, 20 cases) received treatment by syndrome typing. Those in the combination group (17 cases) used the two methods. The therapeutic efficacy and the occurrence of adverse reactions were observed in the 3 groups. The inner disturbance of wind and damp syndrome accompanied qi and yin deficiency syndrome and stasis in Shen meridian syndrome was most often seen in these patients. It accounted for 75.0% in the CM group, 60.9% in the WM group, and 82.4% in the combination group. Totally 54 patients completed this trial. Of them, there were 19 in the CM group, 19 in the WM group, and 16 in the combination group. There was no significant difference in the total effective rate of Chinese medicine syndrome among the 3 groups (84.2%, 78.9%, and 87.5%, respectively) (P>0.05). As for the total effective rate of WM, it was obviously higher in the combination group than in the WM group and the CM group (100.0%, 94.7%, and 94.7%, respectively) (PBenazepril combined with wind dispelling and dampness removing Chinese herbs showed favorable renal protective effects.

2007-01-03

Traditional Chinese medicine (TCM) has been widely practiced and is considered as an attractive to conventional medicine. Multi-herb recipes have been routinely used in TCM. These have been formulated by using TCM-defined herbal properties (TCM-HPs), the scientific basis of which is unclear. The usefulness of TCM-HPs was evaluated by analyzing the distribution pattern of TCM-HPs of the constituent herbs in 1161 classical TCM prescriptions, which shows patterns of multi-herb correlation. Two artificial intelligence (AI) methods were used to examine whether TCM-HPs are capable of distinguishing TCM prescriptions from non-TCM recipes. Two AI systems were trained and tested by using 1161 TCM prescriptions, 11,202 non-TCM recipes, and two separate evaluation methods. These systems correctly classified 83.1-97.3% of the TCM prescriptions, 90.8-92.3% of the non-TCM recipes. These results suggest that TCM-HPs are capable of separating TCM prescriptions from non-TCM recipes, which are useful for formulating TCM prescriptions and consistent with the expected correlation between TCM-HPs and the physicochemical properties of herbal ingredients responsible for producing the collective pharmacological and other effects of specific TCM prescriptions.

Chinese Herbal Medicine for the Optimal Management of Polycystic Ovary Syndrome.

Ong, Madeleine; Peng, Jie; Jin, Xingliang; Qu, Xianqin

2017-01-01

Polycystic ovary syndrome (PCOS) is a complex heterogeneous disorder characterized by androgen excess and ovulatory dysfunction; it is now known to be closely linked to metabolic syndrome. Recent research suggests that insulin resistance plays an important role in the pathogenesis of PCOS which may lead to the excessive production of androgens by ovarian theca cells. Currently there is no single drug that can treat both the reproductive and metabolic complications of the disorder. Existing pharmaceutical agents such as hormonal therapies have been associated with side effects and are not appropriate for PCOS women with infertility. Additionally, insulin sensitizing agents useful for treating the metabolic abnormalities in PCOS have limited efficacy for treating reproductive aspects of the disorder. Chinese herbal medicines have a long history of treating gynaecological problems and infertility and therefore may be a novel approach to the treatment of PCOS. Current research demonstrates that the compounds isolated from herbs have shown beneficial effects for PCOS and when combined in an herbal formula can target both reproductive and metabolic defects simultaneously. Therefore, further investigation into Chinese herbal medicine in the treatment of PCOS is warranted.

The gradual development of Chinese medicine is based on constant accumulation and summary of experience in clinical practice, but without the benefit of undergoing the experimental medicine stage. Although Chinese medicine has formed a systematic and unique theory system through thousands of years, with the development of evidence-based medicine, the bondage of the research methods of experience medicine to Chinese medicine is appearing. The rapid transition and transformation from experience medicine to evidence-based medicine have become important content in the development of Chinese medicine. According to the features of Chinese medicine, we propose the research idea of "taking two ways simultaneously," which is the study both in the ideal condition and in the real world. Analyzing and constructing the theoretical basis and methodology of clinical research in the real world, and building the stage for research technique is key to the effective clinical research of Chinese medicine. Only by gradually maturing and completing the clinical research methods of the real world could we realize "taking two ways simultaneously" and complementing each other, continuously produce scientific and reliable evidence of Chinese medicine, as well as transform and develop Chinese medicine from experience medicine to evidence-based medicine.

Application of clinical phytology in treatment of oncology diseases was limited by intensive development of chemical pharmaceuticals and surgery. The authors had set the task to develop the computer database for phytotherapy application. The database included full information on patient's clinical status (identified diseases, symptoms, syndromes) and applied phytotherapy treatment. Special attention was paid to the application of phyto preparations containing chitosan. The computer database contains information on 2335 patients. It supports reliable data on efficiency of phytotherapy in general and allows to evaluate the efficiency of some particular medicinal herbs and to develop efficient complex phyto preparations for treatment of specific diseases. The application of phytotherapy in treatment of oncology patients confirmed the positive effect on patient's quality of life. In conclusion it should be emphasized that the present situation of practical application of phytotherapy could be considered as unacceptable because of absence of necessary knowledge and practical experience in using phytotherapy in outpatient clinics, hospitals and medicinal centers.

Traditional Chinese medicine (TCM) has long been used for patients with psoriasis. This study aimed to investigate TCM usage in patients with psoriasis. We analyzed a cohort of one million individuals representing the 23 million enrollees randomly selected from the National Health Insurance Research Database in Taiwan. We identified 28,510 patients newly diagnosed with psoriasis between 2000 and 2010. Among them, 20,084 (70.4%) patients were TCM users. Patients who were female, younger, white-collar workers and lived in urbanized area tended to be TCM users. The median interval between the initial diagnosis of psoriasis to the first TCM consultation was 12 months. More than half (N = 11,609; 57.8%) of the TCM users received only Chinese herbal medicine. Win-qing-yin and Bai-xian-pi were the most commonly prescribed Chinese herbal formula and single herb, respectively. The core prescription pattern comprised Mu-dan-pi, Wen-qing-yin, Zi-cao, Bai-xian-pi, and Di-fu-zi. Patients preferred TCM than Western medicine consultations when they had metabolic syndrome, hepatitis, rheumatoid arthritis, alopecia areata, Crohn's disease, cancer, depression, fatty liver, chronic airway obstruction, sleep disorder, and allergic rhinitis. In conclusion, TCM use is popular among patients with psoriasis in Taiwan. Future clinical trials to investigate its efficacy are warranted. PMID:27822287

Chinese medicine prescriptions are a type of medical documents written by doctors after they understand the patients' conditions for syndrome differentiation. Chinese medicine prescriptions are also the basis for pharmacy personnel to dispense medicines and guide patients to use drugs. It has the legal, technical and economic significances. Chinese medicine prescriptions contain such information of names, quantity and usage. Whether the names of drugs in Chinese medicine prescriptions are standardized or not is directly related to the safety and efficacy of the drugs. At present, nonstandard clinical prescriptions are frequently seen. With "Chinese medicine prescription", "names of drug in Chinese medicine prescription" and "standards of Chinese medicine prescription" as key words, the author searched CNKI, Wanfang and other databases, and consulted nearly 100 literatures, so as to summarize current names of drugs in traditional Chinese medicine prescription, analyze the reasons, and give suggestions, in the expectation of standardizing the names of drugs used in traditional Chinese medicine prescriptions.

The common Aconitum herbs in clinical application mainly include Aconiti Radix(Chuanwu), Aconiti Kusnezoffii Radix(Caowu) and Aconiti Lateralis Radix Praeparaia(Fuzi), all of which have toxicity. Therefore, the safety of using Chinese patent drugs including Aconitum herbs has become an hot topic in clinical controversy. Based on the data-mining methods, this study explored the characteristics and causes of adverse drug reactions/events (ADR/ADE) of the Chinese patent drugs including Aconitum, in order to provide pharmacovigilance and rational drug use suggestions for clinical application. The detailed ADR/ADE reports about the Chinese patent drugs including Aconitum herbs were retrieved in the domestic literature databases since 1984 to now. The information extraction and data-mining were conducted based on the platforms of Microsoft office Excel 2016, Clementine 12.0 and Cytoscape 3.3.0. Finally, 78 detailed ADR/ADE reports involving a total of 30 varieties were included. 92.31% ADR/ADE were surely or likely led by the Chinese patent drugs including Aconitum, mostly involving multiple system/organ damages with good prognosis, and even 1 case of death. The incidence of included ADRs/ADEs was associated with various factors such as the patient idiosyncratic, drug toxicity, as well as clinical medication. The patient age was most closely related to ADR/ADEs, and those aged from 60 to 69 were more easily suffered from the ADRs/ADEs of Chinese patent drugs including Aconitum. The probability of ADR/ADEs for the drugs including Chuanwu or Caowu was greater than that of Fuzi, and the using beyond the instructions dose was the most important potential safety hazard in the clinical medication process. For the regular and characteristics of ADR/ADEs led by Chinese patent drugs including Aconitum, special attention shall be paid to the elder patients or with the patients with allergies; strictly control the dosage and course of treatment, strengthen the safety medication

In literature on Korean medicine, Dongeuibogam (Treasured Mirror of Eastern Medicine), published in 1613, represents the overall results of the traditional medicines of North-East Asia based on prior medicinal literature of this region. We utilized this medicinal literature by text mining to establish a list of candidate herbs for cognitive enhancement in the elderly and then performed an evaluation of their effects. Text mining was performed for selection of candidate herbs. Cell viability was determined in HT22 hippocampal cells and immunohistochemistry and behavioral analysis was performed in a kainic acid (KA) mice model in order to observe alterations of hippocampal cells and cognition. Twenty four herbs for cognitive enhancement in the elderly were selected by text mining of Dongeuibogam. In HT22 cells, pretreatment with 3 candidate herbs resulted in significantly reduced glutamate-induced cell death. Panax ginseng was the most neuroprotective herb against glutamate-induced cell death. In the hippocampus of a KA mice model, pretreatment with 11 candidate herbs resulted in suppression of caspase-3 expression. Treatment with 7 candidate herbs resulted in significantly enhanced expression levels of phosphorylated cAMP response element binding protein. Number of proliferated cells indicated by BrdU labeling was increased by treatment with 10 candidate herbs. Schisandra chinensis was the most effective herb against cell death and proliferation of progenitor cells and Rehmannia glutinosa in neuroprotection in the hippocampus of a KA mice model. In a KA mice model, we confirmed improved spatial and short memory by treatment with the 3 most effective candidate herbs and these recovered functions were involved in a higher number of newly formed neurons from progenitor cells in the hippocampus. These established herbs and their combinations identified by text-mining technique and evaluation for effectiveness may have value in further experimental and clinical

Each plant has its own optimal drying temperature, especially for the medicinal herbs, because they are sensitive to heat. If the drying temperature becomes more than the optimal value, some chemical reactions will occur and influence the quality of the dried herb, such as color, taste, and aroma. While if the drying temperature becomes lower than the optimal value, the drying process will slow down; and consequently an expected degradation in the quality of the herb may occur, due to insects and fungi infestation which increase in moist conditions. This paper presents a new temperature control technique for a medicinal herb dryer system. The technique fixes the drying temperature of the medicinal herbs at 40 degree C, even in cases of rapidly changing atmospheric conditions. The control of the dryer temperature is achieved through using the proportional integral (PI) controller. The designed dryer contains two systems, which are the thermal and the electrical systems. The thermal system is designed to heat the drying air by using the solar energy and bio-gas fuel. Whereas, the electrical system, which contains a photovoltaic (PV) modules and a battery, is designed to supply the different electrical loads of the dryer system. The control technique is investigated through simulation work by using MATLAB-SIMULINK. The simulation results indicate the high capability of the proposed technique in controlling the drying temperature, even in cases of rapidly changing atmospheric conditions

Western medicine is an evidence-based science, whereas Chinese medicine is more of a healing art. To date, there has been no research that has examined whether students of Western and Chinese medicine differentially engage in, or benefit from, educational activities for narrative medicine. This study fills a gap in current literature with the aim of evaluating and comparing Western and Chinese Medicine students' perceptions of narrative medicine as an approach to learning empathy and professionalism. An initial 10-item questionnaire with a 5-point Likert scale was developed to assess fifth-year Western medical (MS) and traditional Chinese medical (TCMS) students' perceptions of a 4-activity narrative medicine program during a 13-week internal medicine clerkship. Exploratory factor analysis was undertaken. The response rate was 88.6% (412/465), including 270 (65.5%) MSs and 142 (34.5%) TCMSs, with a large reliability (Cronbach alpha = 0.934). Three factors were extracted from 9 items: personal attitude, self-development/reflection, and emotional benefit, more favorable in terms of enhancement of self-development/reflection. The perceptions of narrative medicine by scores between the two groups were significantly higher in TCMSs than MSs in all 9-item questionnaire and 3 extracted factors. Given the different learning cultures of medical education in which these student groups engage, this suggests that undertaking a course in Chinese medicine might enhance one's acceptance to, and benefit from, a medical humanities course. Alternatively, Chinese medicine programmes might attract more humanities-focused students.

Full Text Available Abstract Background The goal of our study was to evaluate the effects of different medicinal herbs rich in polyphenol (Lemon balm, Sage, St. John's wort and Small-flowered Willowherb used as dietary supplements on bioaccumulation of some essential metals (Fe, Mn, Zn and Cu in different chicken meats (liver, legs and breast. Results In different type of chicken meats (liver, legs and breast from chickens fed with diets enriched in minerals and medicinal herbs, beneficial metals (Fe, Mn, Zn and Cu were analysed by flame atomic absorption spectrometry. Fe is the predominant metal in liver and Zn is the predominant metal in legs and breast chicken meats. The addition of metal salts in the feed influences the accumulations of all metals in the liver, legs and breast chicken meat with specific difference to the type of metal and meat. The greatest influences were observed in legs meat for Fe and Mn. Under the influence of polyphenol-rich medicinal herbs, accumulation of metals in the liver, legs and breast chicken meat presents specific differences for each medicinal herb, to the control group that received a diet supplemented with metal salts only. Great influence on all metal accumulation factors was observed in diet enriched with sage, which had significantly positive effect for all type of chicken meats. Conclusions Under the influence of medicinal herbs rich in different type of polyphenol, accumulation of metals in the liver, legs and breast chicken meat presents significant differences from the group that received a diet supplemented only with metal salts. Each medicinal herb from diet had a specific influence on the accumulation of metals and generally moderate or poor correlations were observed between total phenols and accumulation of metals. This may be due to antagonism between metal ions and presence of other chelating agents (amino acids and protein from feeding diets which can act as competitor for complexation of metals and influence

Full Text Available Endothelin-1 receptors (ETAR and ETBR act as a pivotal regulator in the biological effects of ET-1 and represent a potential drug target for the treatment of multiple cardiovascular diseases. The purpose of the study is to discover dual ETA/ETB receptor antagonists from traditional Chinese herbs. Ligand- and structure-based virtual screening was performed to screen an in-house database of traditional Chinese herbs, followed by a series of in vitro bioassay evaluation. Aristolochic acid A (AAA was first confirmed to be a dual ETA/ETB receptor antagonist based intracellular calcium influx assay and impedance-based assay. Dose-response curves showed that AAA can block both ETAR and ETBR with IC50 of 7.91 and 7.40 μM, respectively. Target specificity and cytotoxicity bioassay proved that AAA is a selective dual ETA/ETB receptor antagonist and has no significant cytotoxicity on HEK293/ETAR and HEK293/ETBR cells within 24 h. It is a feasible and effective approach to discover bioactive compounds from traditional Chinese herbs using in silico screening combined with in vitro bioassay evaluation. The structural characteristic of AAA for its activity was especially interpreted, which could provide valuable reference for the further structural modification of AAA.

The presence of hair plays an important role in people's overall physical appearance and self-perception. As a result of increased life expectancy, the desire to look youthful plays a bigger role than ever.The use of medicinal plants is as old as mankind and the market will face many new products containing natural oils and herbs in coming years. In traditional Iranian medicine, many plants and herbal formulations are reported for hair growth as well as the improvement in hair quality. The aim of this article is to introduce effective medicinal plants in traditional Iranian medicine to prevent gray hair and advocate them as the new products. The present investigation is an overview study and has been codified by library search in the main sources of traditional Iranian medicine. In traditional Iranian medicine, three types of formulations are proposed to prevent gray hair, namely (i) treatment compounds, (ii) preventive compounds, and (iii) hair dyes to color gray hairs. Our search showed that the main parts of a plant that is used in the treatment and preventive compounds are seeds and fruits. These are primarily in the form of topical oil or oral compound (electuary). The majority of plant parts used in hair dyes is from the fruit and/or leaves. Natural products are highly popular and the use of plant extracts in formulations is on the rise. This is because synthetic based product may cause health hazards with several side effects. Considering the increased popularity of herbal drugs in hair care, it is worthwhile to conduct systemic investigation on the production and efficacy of these drugs. We trust that our investigation would encourage the use of traditional Iranian medicine in future hair care products.

Beneficial effects of herbs, spices and medicinal plants on the metabolic syndrome, brain and cognitive function.

Herbs and spices have been used since ancient times to not only improve the flavor of edible food but also to prevent and treat chronic health maladies. While the scientific evidence for the use of such common herbs and medicinal plants then had been scarce or lacking, the beneficial effects observed from such use were generally encouraging. It is, therefore, not surprising that the tradition of using such herbs, perhaps even after the advent of modern medicine, has continued. More recently, due to an increased interest in understanding the nutritional effects of herbs/spices more comprehensively, several studies have examined the cellular and molecular modes of action of the active chemical components in herbs and their biological properties. Beneficial actions of herbs/spices include anti-inflammatory, antioxidant, anti-hypertensive, gluco-regulatory, and anti-thrombotic effects. One major component of herbs and spices is the polyphenols. Some of the aforementioned properties are attributed to the polyphenols and they are associated with attenuating the metabolic syndrome. Detrimental changes associated with the metabolic syndrome over time affect brain and cognitive function. Metabolic syndrome and type-2 diabetes are also risk factors for Alzheimer's disease and stroke. In addition, the neuroprotective effects of herbs and spices have been demonstrated and, whether directly or indirectly, such beneficial effects may also contribute to an improvement in cognitive function. This review evaluates the current evidence available for herbs/spices in potentially improving the metabolic syndrome, as well as their neuroprotective effects on the brain, and cognitive function in animal and human studies.

The herbs used as the material for traditional Chinese medicine are mostly planted at mountain areas where there is appropriate weather condition. Due to the complex terrain condition in mountain area, the planting at such places is always associated with a scattered pattern, which inevitably bring difficulty to the work of accurate measurement for the planting area. Advanced research about monitoring the planting area for medicine-herb under complex environmental condition is so critical and meaningful for developing the medicine-herb planting to a large scale and an industry. Therefore, this research, taking the planting of Herpetospermum pedunculosum in Luding county as an example, utilizes RS&GIS: using the image data from TM and ETM datum as the remote sensing information source, integrating GPS data from quadrat survey on the spots, and analyzing on a GIS platform, to extract the planting area of H. pedunculosum in Luding county. The results indicate that: (1) the method and technology used to estimate the planting area of H. pedunculosum are feasible and can be applied to monitoring the planting area of medicine-herb at mountain area under complex environmental conditions: (2) the planting area of H. pedunculosum in Luding county is estimated to be 857. 246 acres by the methods utilized in this research, which is closed to the value from local statistical data with an error range less than 5%; (3) in consideration of those inevitable errorrs generating from the procedures such as remote sensing data acquisition, data preprocessing, data interpretation, and so on, and the fact that the classification of remote sensing data, which must be implemented by those above procedures, was used directly to extract the herb type, the accuracy of area estimation for the herb is significantly influenced by the accuracy of classification for herb type, and the estimated area is inevitably associated with some error.

Radioactivity is the phenomenon of spontaneous emission of short waves radiations. It is toxic to Bio Organisms. But it can be used to analyze toxic as well as Nutritional Elements, when powdered sample of plants and herbs irradiated with thermal neutrons (γ-radiation). The Nutritional Elements Acquire Artificial radioactivity and emits radiation which is used to analyze the Elements by Instrumental Neutron Activation Analysis. Plants and Herbs use known to be reservoir of various metabolite. Minerals are primary metabolite and play vital role in the regulation of the metabolic activity in the body as well as formation of body structure and skeleton. Many trace elements play a vital role in the general well being as well as cure of diseases. Role of metals in curing ailment was first realized in Ayurveda. It is reviewed that the herbal medicines can supply the deficient element in a bioavailable form and the person suffering from its deficiency can be easily cured. Therefore an attempt has been made to evaluate the Medicinal Potential in some medicinal herbs use as brain tonic by using Induced Couple Plasma Spectroscopy, Instrumental Neutron Activation Analysis. We have analyzed sixteen medicinal herbs for four bulk elements (Na, K, Ca, Mg) and nine trace elements (Fe, Cr, Mn, Co, Cu, Zn, Ni, Cd, Pb). In order to check quality assurance and validation of elemental data eight biological standard Reference Materials (BSRMS) are also analyzed. Accuracy and precision measurements were carried out by replicate analysis. Our data should be reliable within ± 10%. On the basis of elemental data in sixteen medicinal herbs commonly used as brain tonic and vitalizer, it is concluded that Amala, Gokshur, Yastimadhu, Sankhpuspi most enriched in Fe, Ca, Mg and other nutritional elements specially Mn, Cu, Zn,. No particular herb is enriched in all elements. Elemental contents of environmental contaminants such Ni, Cd, Pb, Hg, are minimal so as not to cause any harm to our body

Leaf carbon isotope ratios and 13 kinds of mineral elements were measured on 36 species of common Chinese medicinal plants in a subtropical monsoon forest of Ding Hu Shan in Guangdong Province. The .delta.13C value were from -26.4 to -32.6%, indicating that all of the species belonged the photosynthetic C3 types. The relative lower value of δ13C was observed in the life form of shrubs. The contents of 7 elements (N, P, K, Ca, Na Mg, Si) were dependent upon the species, life form, medicinal function and medicinal part. Herb type medicine and the used medicinal part of leaves or whole plant showed higher levels of above elements than the others. Among the nine groups with different medicinal functions, it was found that more nitrogen was in the leaves of medicinal plants for hemophthisis, hypertension and stomachic troubles, more phosphorus and potassium were in the leaves for cancer and snake bite medicines, but more calcium and magnesium were in the leaves for curing rheumatics. Ferric, aluminium and manganese were the main composition of microelements in leaves. There were higher content of ferric in leaves for hemophthisis medicine, higher zinc in leaves for cold and hypertension medicine, and higher Cup in leaves of stomachic medicine. It was suggested that the pattern of mineral elements in leaves of Chinese medicinal plants reflected the different properties of absorption and accumulation. Some additional effect due to the high content of certain element might be associated with the main function of that medicine

Patients who were female, younger, white-collar workers and lived in urbanized area tended to be TCM users. The median interval between the initial diagnosis of psoriasis to the first TCM consultation was 12 months. More than half (N=11,609; 57.8% of the TCM users received only Chinese herbal medicine. Win-qing-yin and Bai-xian-pi were the most commonly prescribed Chinese herbal formula and single herb, respectively. The core prescription pattern comprised Mu-dan-pi, Wen-qing-yin, Zi-cao, Bai-xian-pi, and Di-fu-zi. Patients preferred TCM than Western medicine consultations when they had metabolic syndrome, hepatitis, rheumatoid arthritis, alopecia areata, Crohn’s disease, cancer, depression, fatty liver, chronic airway obstruction, sleep disorder, and allergic rhinitis. In conclusion, TCM use is popular among patients with psoriasis in Taiwan. Future clinical trials to investigate its efficacy are warranted.

Patients in Taiwan with allergic rhinitis seek not only Western medicine treatment but also Traditional Chinese Medicine treatment or integrated Chinese-Western medicine treatment. Various studies have conducted pairwise comparison on Traditional Chinese Medicine, Western medicine, and integrated Chinese-Western medicine treatments. However, none conducted simultaneous analysis of the three treatments. This study analyzed patients with allergic rhinitis receiving the three treatments to identify differences in demographic characteristic and medical use and thereby to determine drug use patterns of different treatments. The National Health Insurance Research Database was the data source, and included patients were those diagnosed with allergic rhinitis (International Classification of Diseases, Ninth Revision, Clinical Modification codes 470-478). Chi-square test and Tukey studentized range (honest significant difference) test were conducted to investigate the differences among the three treatments. Visit frequency for allergic rhinitis treatment was higher in female than male patients, regardless of treatment with Traditional Chinese Medicine, Western medicine, or integrated Chinese-Western medicine. Persons aged 0-19 years ranked the highest in proportion of visits for allergic rhinitis. Traditional Chinese Medicine treatment had more medical items per person-time and daily drug cost per person-time and had the lowest total expenditure per person-time. In contrast, Western medicine had the lowest daily drug cost per person-time and the highest total expenditure per person-time. The total expenditure per person-time, daily drug cost per person-time, and medical items per person-time of integrated Chinese-Western medicine treatment lay between those seen with Traditional Chinese Medicine and Western medicine treatments. Although only 6.82 % of patients with allergic rhinitis chose integrated Chinese-Western medicine treatment, the visit frequency per person-year of

By using traditional Chinese medicine inheritance support system to analyze the dominant experience and recessive principles of the prescriptions for stranguria in the dictionary of traditional Chinese medicine prescription (DCMP), we aim to define the medication pattern and rule and to acquire new prescriptions. In dominant experience analysis, we were able to find 22 drugs used over 50 times, including drugs of clearing heat, diuresis and relieving stranguria which are the most used and drugs of clearing heat, cooling blood, benefiting Qi and nourishing Yin. In addition, drugs of activating Qi and Xue, eliminating phlegm and removing toxic are often used, including 34 herb pairs and 5 combinations of three-taste drugs are used more than 35 times. These results fully reflect the composition principles and compatibility characteristic of prescriptions for treating stranguria in DCMP. Thirteen new prescriptions by way of recessive principle excavating were acquired. These new prescriptions might be suitable to clinical treatments of variable syndromes. This article provides an useful clue to research and produce new drugs.

Chai hu (Bupleuri radix), one of the most frequently used herbs in Chinese herbal medicine, has 3 major functions, depending on dosage and combination with other herbs. The aim of this study was to investigate how chai hu is prescribed in everyday practice in Switzerland, and whether these prescription patterns reflect its various applications. A random sample of 1,053 prescriptions was drawn from the database of Lian Chinaherb AG, Wollerau, Switzerland, and analyzed regarding the most frequently used classical formulas containing chai hu, daily dosages and combinations with other herbs. 29.0% of all prescriptions contained chai hu, and 98.0% of these were in granular form. The most frequently used classical formulas were xiao yao san ('rambling powder'), jia wei xiao yao san ('augmented rambling powder') and chai hu shu gan san ('Bupleurum powder to spread the liver'). In more than half of the prescriptions, chai hu was combined with bai shao (Paeoniae Radix Alba), dang gui (Angelicae sinensis radix) or fu ling (Poria). 51.8% of the prescriptions contained a low daily dosage of chai hu, 24.9% a medium and 15.1% a high dosage. Chai hu was generally prescribed in classic combinations with other herbs and in a medium dosage. Due to the addition of supplementary herbs to classical formulas, its daily dose was often diminished from a high or medium dose to a low dose. This raises the question if chai hu would then still exert its desired function of, e.g., moving liver-qi in these prescriptions.

Breast cancer is the most common carcinoma in women. Comprehensive therapy on breast cancer including surgical operation, chemotherapy, radiotherapy, endocrinotherapy, etc. could help, but still has serious side effect and resistance against anticancer drugs. Complementary and alternative medicine (CAM) may avoid these problems, in which traditional Chinese medicine (TCM) has been highlighted. In this section, to analyze the mechanism through which TCM act on breast cancer, we have built a virtual model consisting of the construction of database, oral bioavailability prediction, drug-likeness evaluation, target prediction, network construction. The 20 commonly employed herbs for the treatment of breast cancer were used as a database to carry out research. As a result, 150 ingredient compounds were screened out as active molecules for the herbs, with 33 target proteins predicted. Our analysis indicates that these herbs 1) takes a 'Jun-Chen-Zuo-Shi" as rule of prescription, 2) which function mainly through perturbing three pathways involving the epidermal growth factor receptor, estrogen receptor, and inflammatory pathways, to 3) display the breast cancer-related anti-estrogen, anti-inflammatory, regulation of cell metabolism and proliferation activities. To sum it up, by providing a novel in silico strategy for investigation of the botanical drugs, this work may be of some help for understanding the action mechanisms of herbal medicines and for discovery of new drugs from plants.

Background : Traditional Chinese Medicine (TCM) with its focus on herbal use is popular and appreciated worldwide with increased tendency, although its therapeutic efficacy is poorly established for most herbal TCM products. Treatment was perceived as fairly safe but discussions emerged more recently as to whether herb induced liver injury (HILI) from herbal TCM is a major issue; Methods : To analyze clinical and case characteristics of HILI caused by herbal TCM, we undertook a selective literature search in the PubMed database with the search items Traditional Chinese Medicine, TCM, alone and combined with the terms herbal hepatotoxicity or herb induced liver injury; Results : HILI caused by herbal TCM is rare and similarly to drugs can be caused by an unpredictable idiosyncratic or a predictable intrinsic reaction. Clinical features of liver injury from herbal TCM products are variable, and specific diagnostic biomarkers such as microsomal epoxide hydrolase, pyrrole-protein adducts, metabolomics, and microRNAs are available for only a few TCM herbs. The diagnosis is ascertained if alternative causes are validly excluded and causality levels of probable or highly probable are achieved applying the liver specific RUCAM (Roussel Uclaf Causality Assessment Method) as the most commonly used diagnostic tool worldwide. Case evaluation may be confounded by inappropriate or lacking causality assessment, poor herbal product quality, insufficiently documented cases, and failing to exclude alternative causes such as infections by hepatotropic viruses including hepatitis E virus infections; Conclusion : Suspected cases of liver injury from herbal TCM represent major challenges that deserve special clinical and regulatory attention to improve the quality of case evaluations and ascertain patients' safety and benefit.

In recent years, herbs have been researched for new drug candidates because they have a long empirical history of treating diseases and are relatively free from side effects. Studies to scientifically prove the medical efficacy of herbs for target diseases often spend a considerable amount of time and effort in choosing candidate herbs and in performing experiments to measure changes of marker genes when treating herbs. A computational approach to recommend herbs for treating diseases might be helpful to promote efficiency in the early stage of such studies. Although several databases related to traditional Chinese medicine have been already developed, there is no specialized Web tool yet recommending herbs to treat diseases based on disease-related genes. Therefore, we developed a novel search engine, HerDing, focused on retrieving candidate herb-related information with user search terms (a list of genes, a disease name, a chemical name or an herb name). HerDing was built by integrating public databases and by applying a text-mining method. The HerDing website is free and open to all users, and there is no login requirement.

Based on the data collected by the census team in the national census information management system, the spatial autocorrelation analysis method was used to analyze the similarity of the richness of Chinese herbal medicine resources in the investigated counties. The results showed that the species richness in the investigated counties appeared a tendency to focus on the distribution of the characteristics. Among them, the areas with sparse resources are concentrated in most areas of the north of the Yangtze River, northwest and most areas of Tibet. The areas with abundant resources are concentrated in the areas south of the Yangtze River. The results showed that there were significant differences in the abundance of traditional Chinese medicine resources between regions. The results showed that there were significant differences in the abundance of traditional Chinese medicine resources between regions. Due to the large differences in the land area between the county and the richness of the types of traditional Chinese medicine resources, it is proposed to increase the land area of the traditional Chinese medicine resource census when allocating the fourth national census of Chinese medicine resources by the "factor method", and the richness of traditional Chinese medicine and other indicators, in order to give full play to the efficiency of transfer payment system. Based on the county area and the rich variety of traditional Chinese medicine resources, combined with the national drug resources census pilot work carried out, it is recommended to focus on attention and support in the national medicine resources census work, personnel team, funding, summary of results on the western and southern provinces.

This first-attempt study used extracts of appropriate antioxidant abundant Camellia and non-Camellia tea and medicinal herbs as model ESs to stably intensify bioelectricity generation performance in microbial fuel cells (MFCs). As electron shuttles (ESs) could stimulate electron transport phenomena by significant reduction of electron transfer resistance, the efficiency of power generation for energy extraction in microbial fuel cells (MFCs) could be appreciably augmented. Using environmentally friendly natural bioresource as green bioresource of ESs is the most promising to sustainable practicability. As comparison of power-density profiles indicated, supplement of Camellia tea extracts would be the most appropriate, then followed non-Camellia Chrysanthemum tea and medicinal herbs. Antioxidant activities, total phenolic contents and power stimulating activities were all electrochemically associated. In particular, the extract of unfermented Camellia tea (i.e., green tea) was the most promising ESs to augment bioenergy extraction compared to other refreshing medicinal herb extracts.

At the beginning of the ancient "Silk Road", traditional Chinese medicine resources (TCM resources) have long been integrated into it, and it was once the "important part" of the ancient "Silk Road" in Chinese history, benefited from this, the political connections was strengthened, the economic and trade was developed, and Chinese medicine culture was spread. Before Qing Dynasty, people took out the "silk" and brought back "herbs" on the "Silk Road", which enriched China's medicinal resources. While in the later Qing Dynasty and the period of the Republic of China, more scientific and technological methods were brought back from abroad, and this in turn enriched the medical research methods. With more than 2 000 years' development, China's boundaries have changed countless times, therefore the word "Foreign" has different meanings in different historical periods. The import, development and utilization of foreign TCM resources is different in different historical periods, at present, with the continuous enhancement of China's comprehensiv national strength，especially the "Belt And Road" strategy, the communication and import of TCM resources with countries that participating in the "Belt and Road" initiativ became much easier. In order to actively respond to the "Belt and Road" initiative promote the development and utilization of foreign medicinal resources; serve people from the countries participating in the "Belt and Road" initiative we sorted out the foreign TCM resources from different periods in ancient and modern China, and based on this, we proposed the strategy of import of foreign TCM resources under the new situation, those are: "three levels, four steps, one support and one key". And "three levels" refers to intelligence collection level, field investigation level, scientific research level, "Four steps" refers to the original identification research, safety evaluation research, functional positioning research and medicinal properties research; "One

Unfortunately, the usual anti-fat drugs are associated with high morbidity in fetus and due to people's inclination towards taking herbs, it is required to identify side effects of medicinal herbs in pregnancy. The aim of this study was to present hypolipidemic herbs that would not any complications for mother and fetus. METHODS: In this review article, the major electronic databases such as EBSCO, Central Register of Controlled Trials (CENTRAL, China Network Knowledge Infrastructure (CNKI, Cochrane, Google scholar, MEDLINE, SciVerse, Scopus, and Web of Science were searched using the key words “herbal” and “hyperlipidemia”, “herbal” and “pregnancy” matched by MeSH from their respective inceptions till September, 2016. Total of 1723 publications (145 review articles, 855 original research articles, and 723 abstracts about the effect of herbals on hyperlipidemia and 682 publications (200 abstracts, 423 original research articles, and 59 review articles about the effect of herbals in pregnancy were retrieved. At the end, a list of medicinal plants effective on hyperlipidemia alongside their effects on pregnancy was developed. Finally, the plants effective on hyperlipidemia and safe during pregnancy were determined and their dosage, complications, mechanism of action, and side effects were reported. RESULTS: A total of 110 effective herbs on hyperlipidemia were identified and complications of 95 plants in pregnancy were studied. At last, among the 55 selected plants effective on hyperlipidemia and examined for pregnancy, we reported 12 herbs with their dosage and special considerations that can be used to treat hyperlipidemia during pregnancy. CONCLUSION: Some medicinal plants can be used to treat hyperlipidemia during pregnancy without any significant side effects both on mother or fetus.

Large-scale pharmaco-epidemiological studies of Chinese herbal medicine (CHM) for treatment of urticaria are few, even though clinical trials showed some CHM are effective. The purpose of this study was to explore the frequencies and patterns of CHM prescriptions for urticaria by analysing the population-based CHM database in Taiwan. This study was linked to and processed through the complete traditional CHM database of the National Health Insurance Research Database in Taiwan during 2009. We calculated the frequencies and patterns of CHM prescriptions used for treatment of urticaria, of which the diagnosis was defined as the single ICD-9 Code of 708. Frequent itemset mining, as applied to data mining, was used to analyse co-prescription of CHM for patients with urticaria. There were 37,386 subjects who visited traditional Chinese Medicine clinics for urticaria in Taiwan during 2009 and received a total of 95,765 CHM prescriptions. Subjects between 18 and 35 years of age comprised the largest number of those treated (32.76%). In addition, women used CHM for urticaria more frequently than men (female:male = 1.94:1). There was an average of 5.54 items prescribed in the form of either individual Chinese herbs or a formula in a single CHM prescription for urticaria. Bai-Xian-Pi (Dictamnus dasycarpus Turcz) was the most commonly prescribed single Chinese herb while Xiao-Feng San was the most commonly prescribed Chinese herbal formula. The most commonly prescribed CHM drug combination was Xiao-Feng San plus Bai-Xian-Pi while the most commonly prescribed triple drug combination was Xiao-Feng San, Bai-Xian-Pi, and Di-Fu Zi (Kochia scoparia). In view of the popularity of CHM such as Xiao-Feng San prescribed for the wind-heat pattern of urticaria in this study, a large-scale, randomized clinical trial is warranted to research their efficacy and safety.

Full Text Available Despite the growth of traditional Chinese medicine (TCM and western herbal medicine (WHM research in Australia, little is known about how ethics committees (HRECs assess the ethics of TCM or WHM research. The objectives of this study were to examine the experiences of TCM and WHM researchers and HRECs with the evaluation of ethics applications. Two cross-sectional surveys were undertaken of HRECs and TCM and WHM researchers in Australia. Anonymous self-completion questionnaires were administered to 224 HRECs and 117 researchers. A response confirming involvement in TCM or WHM research applications was received from 20 HRECs and 42 researchers. The most frequent ethical issues identified by HRECs related to herbal products including information gaps relating to mode of action of herbal medicines and safety when combining herbal ingredients. Researchers concurred that they were frequently requested to provide additional information on multiple aspects including safety relating to the side effects of herbs and herb-drug interactions. Overall adherence with the principles of ethical conduct was high among TCM and WHM researchers although our study did identify the need for additional information regarding assessment of risk and risk management.

Traditional Chinese medicine (TCM) has remained an integral part of Chinese culture and society for thousands of years. In Taiwan TCM is a recognized element of its National Health Insurance Scheme. However, there is no knowledge about how TCM is accessed by foreign workers from a non-Asian cultural background. The objectives of this study were to investigate the prevalence and patterns of TCM use among non-Asian white-collar workers living in Taiwan, and examine factors likely to influence their use of TCM. This study applied a cross-sectional survey design. A total of 207 white-collar foreign workers of a non-Asian background currently holding National Health Insurance cards who had lived in Taiwan for 4 months or more participated in this study. The prevalence of TCM use was 45%. The most frequently used therapies were traditional Chinese herbs/medicine and acupuncture. Factors indicating the likelihood of TCM usage were age 31-40 years, visit to an allopathic medical doctor in the last year, ability to read Chinese, having a friend or family member available to assist in the use of TCM, and access to information about TCM services available in Taiwan. Utilization of TCM by people of a non-Asian background living in Taiwan appears to be most influenced by enabling factors including language ability, access to information, and informal reference persons.

The model of Western integrative medicine: the role of Chinese medicine.

Dobos, Gustav; Tao, Iven

2011-01-01

The basic concept of integrative medicine (IM) is that by combining mainstream (biomedicine) with complementary and alternative medicine (CAM), synergistic therapeutic effects can be attained. When the methods of mind/body medicine (MBM) are added to this combination, as in Western countries, a new concept emerges that drastically changes the approach toward illness.It is interesting to note that the joining of traditional Chinese medicine and Western medicine in the early days of the Peoples' Republic of China preceded the Western model of IM by almost 50 years. Several elements that make up the key components of IM as practiced today in the West were already present in the Chinese version of IM, and Chinese medicine has played and continues to play an important role in advancing IM. However, one of the major differences between the Chinese and the Western models of IM today, besides MBM and some other treatment options, is that Western integrative medicine (WIM) strictly requires its CAM methods to be supported by scientific evidence.The therapeutic methods of IM and their applications are many and varied. However, they are most frequently employed to treat chronic medical conditions, e.g., bronchial asthma, rheumatic disease, chronic inflammatory bowel disorder and chronic pain. Other fields in which IM may be applied are internal medicine (inflammatory bowel diseases and cardiovascular diseases), musculoskeletal disorders, oncology (chemotherapy-induced side effects), obstetrics and gynecology (dysmenorrhea, endometriosis, infertility and menopausal complaints), pediatrics, geriatrics, neurology (migraine and chronic headache), and psychiatry (anxiety and depression).The concept of WIM is discussed here in detail by reviewing its scope and implications for the practice of medicine and focusing on the role of Chinese medicine in WIM.

The Chinese herbal decoction formula Xiao Jian Zhong Tang (XJZT) is one of the classic formulas from the classic traditional Chinese medicine (TCM). Previous studies on XJZT found that it is effective for treating peptic ulcer, irritable bowel syndrome, functional gastroenteritis and similar psychosomatic disorders of the digestive organs. It has also been shown that all the herbs used in XJZT contain antioxidants. In this study, we investigated the in vitro DNA protection effect of the individual herb extracts and the whole formula. Water extract of the herbs and XJZT were used to pre-treat human lymphocytes. The lymphocytes were then exposed to hydrogen peroxide. The in vitro DNA protection effect of the herbs was investigated by comet assay. No DNA protective effect (P < 0.05) was found for individual herb extracts, but XJZT showed protection of human lymphocytic DNA upon oxidative stress (P < 0.05). The in vitro DNA protection effect of XJZT was conferred by the synergistic effect of the herbs, while the individual herbs had no such effect.

Herbs and spices have been used as food preservatives, flavorings, and in traditional medicines for thousands of years. More and more scientific evidence supports the medicinal properties of culinary herbs. Colon cancer is the third leading cause of cancer death in the USA, and the fourth most common form of cancer worldwide. The objectives of this study were to evaluate the antitumor activity of five selected herbs grown under greenhouse conditions, and to study the potential synergistic effects among different herbal extract combinations. Thyme, rosemary, sage, spearmint, and peppermint extracts significantly inhibited SW-480 colon cancer cell growth, with sage extracts exhibiting the highest bioactivity, with 50% inhibition at 35.9 µg mL⁻¹, which was equivalent to 93.9 µg dried leaves mL⁻¹ of culture medium. Some mixtures of different herbal extracts had combination effects on cancer cell growth. The inhibitory effects of peppermint + sage combinations at a 1:1 ratio were significantly higher than rosemary + sage combinations at 1:1 ratio, although peppermint extracts showed lower inhibition than rosemary extracts. Extracts from herb species (thyme, rosemary, sage, spearmint and peppermint) can significantly inhibit the growth of human colon cancer cells. Mixtures of herb extracts can have combination effects on cancer cell growth. The study suggests that these five herbs may have potential health benefits to suppress colon cancer.

The quality of Chinese medicinal materials relates greatly to the clinical curative effect and security. In order to ensure the quality and safety of Chinese medicinal materials, a systematic and operable traceability system needs to be established. It can realize the whole process of quality and safety management of Chinese medicinal materials "from production to consumption" through recording and inquiring information and recalling defective products, which is an important direction for the future development of traditional Chinese medicine. But it is still at the exploration and trial stage. In this paper, a framework of Chinese medicinal materials' quality and safety traceability system was established on the basis of the domestic and international experience about the construction of food and agricultural products traceability systems. The relationship between traceability system of Chinese medicinal materials' quality and GAP, GMP, GSP was analyzed, and the possible problems and the corresponding solutions were discussed.

With the development of the knowledge economy, knowledge has become one of the most important resources for social progress and economic development. Some countries have proposed measures for the protection of their own traditional knowledge. Traditional Chinese medicine belongs to the category of intangible cultural heritage because it is an important part of Chinese cultural heritage. Today the value of traditional knowledge of Chinese medicine has been widely recognized by the domestic and international public. This paper discusses the definition of traditional knowledge of Chinese medicine and its protection, and evaluates research on its classification. We review the present status of the protection of traditional knowledge of Chinese medicine and tentatively put forward some possible ideas and methods for the protection of traditional knowledge of Chinese medicine. Our goal is to find a way to strengthen the vitality of traditional Chinese medicine and consolidate its foundation. We believe that if we could establish a suitable sui generis(sui generis is a Latin term meaning "of its own kind" and is often used in discussions about protecting the rights of indigenous peoples. Here we use it to emphasize the fact that protection of traditional knowledge of Chinese medicine cannot be achieved through existing legal means of protection alone due to its unique characteristics) system for traditional knowledge, a more favorable environment for the preservation and development of traditional Chinese medicine will ultimately be created.

High fructose diet-induced metabolic syndrome: Pathophysiological mechanism and treatment by traditional Chinese medicine.

Pan, Ying; Kong, Ling-Dong

2018-04-01

Fructose is a natural monosaccharide broadly used in modern society. Over the past few decades, epidemiological studies have demonstrated that high fructose intake is an etiological factor of metabolic syndrome (MetS). This review highlights research advances on fructose-induced MetS, especially the underlying pathophysiological mechanism as well as pharmacotherapy by traditional Chinese medicine (TCM), using the PubMed, Web of science, China National Knowledge Infrastructure, China Science and Technology Journal and Wanfang Data. This review focuses on de novo lipogenesis (DNL) and uric acid (UA) production, two unique features of fructolysis different from glucose glycolysis. High level of DNL and UA production can result in insulin resistance, the key pathological event in developing MetS, mostly through oxidative stress and inflammation. Some other pathologies like the disturbance in brain and gut microbiota in the development of fructose-induced MetS in the past years, are also discussed. In management of MetS, TCM is an excellent representative in alternative and complementary medicine with a complete theory system and substantial herbal remedies. TCMs against MetS or MetS components, including Chinese patent medicines, TCM compound formulas, single TCM herbs and active compounds of TCM herbs, are reviewed on their effects and molecular mechanisms. TCMs with hypouricemic activity, which specially target fructose-induced MetS, are highlighted. And new technologies and strategies (such as high-throughput assay and systems biology) in this field are further discussed. In summary, fructose-induced MetS is a multifactorial disorder with the underlying complex mechanisms. Current clinical and pre-clinical evidence supports the potential of TCMs in management of MetS. Additionally, TCMs may show some advantages against complex MetS as their holistic feature through multiple target actions. However, further work is needed to confirm the effectivity and safety of TCMs

Traditional Chinese medicine (TCM) prescription is the main therapies for disease prevention and treatment in Chinese medicine. Following the guidance of the theory of TCM and developing drug by composing prescriptions of TCM materials and pieces, it is a traditional application mode of TCM, and still widely used in clinic. TCM prescription has theoretical advantages and rich clinical application experience in dealing with multi-factor complex diseases, but scientific research is relatively weak. The lack of scientific cognition of the effective substances and mechanism of Chinese medicine leads to insufficient understanding of the efficacy regularity, which affects the stability of effect and hinders the improvement of quality of Chinese medicinal products. Component-based Chinese medicine (CCM) is an innovation based on inheritance, which breaks through the tradition of experience-based prescription and realize the transformation of compatibility from herbal pieces to components. CCM is an important achievement during the research process of modernization of Chinese medicine. Under the support of three national "973" projects, in order to reveal the scientific connotation of the prescription compatibility theory and develop innovative Chinese drugs, we have launched theoretical innovation and technological innovation around the "two relatively clear", and opened up the research field of CCM. CCM is an innovation based on inheritance, breaking through the tradition of experience based prescription, and realizing the transformation from compatibility of herbal pieces to component compatibility, which is an important achievement of the modernization of traditional Chinese medicine. In the past more than 10 years, with the deepening of research and the expansion of application, the theory and methods of CCM and efficacy-oriented compatibility have been continuously improved. The value of CCM is not only in developing new drug, more important is to build a

Natural Compounds from Herbs that can Potentially Execute as Autophagy Inducers for Cancer Therapy

Directory of Open Access Journals (Sweden)

Shian-Ren Lin

2017-07-01

Full Text Available Accumulated evidence indicates that autophagy is a response of cancer cells to various anti-cancer therapies. Autophagy is designated as programmed cell death type II, and is characterized by the formation of autophagic vacuoles in the cytoplasm. Numerous herbs, including Chinese herbs, have been applied to cancer treatments as complementary and alternative medicines, supplements, or nutraceuticals to dampen the side or adverse effects of chemotherapy drugs. Moreover, the tumor suppressive actions of herbs and natural products induced autophagy that may lead to cell senescence, increase apoptosis-independent cell death or complement apoptotic processes. Hereby, the underlying mechanisms of natural autophagy inducers are cautiously reviewed in this article. Additionally, three natural compounds—curcumin, 16-hydroxycleroda-3,13-dien-15,16-olide, and prodigiosin—are presented as candidates for autophagy inducers that can trigger cell death in a supplement or alternative medicine for cancer therapy. Despite recent advancements in therapeutic drugs or agents of natural products in several cancers, it warrants further investigation in preclinical and clinical studies.

Numerous people with chronic conditions like to use traditional Chinese medicine (TCM) treatment, or integrated treatment of TCM and Western medicine (WM). Our study explored the associations between multiple chronic conditions (MCC) and TCM use and the use of specific types of TCM therapy among adults in Taiwan. In addition, we explored the TCM use of adults with seven common types of chronic conditions. In our study, a national representative sample in 2005 was used. The Chronic Condition Indicator and the Clinical Classifications System created by the U.S. Agency for Healthcare Research and Quality were used to define the number of chronic conditions of adults. Logistic regressions adjusted for demographic characteristics were used to analyze the associations. The frequency of TCM use among adults with different numbers of chronic conditions was quantified. TCM use for adults with ≥5 chronic conditions (odds ratio [OR] 1.86) was higher than TCM use for adults with 2-4 chronic conditions (OR 1.51) and TCM use for adults with one chronic condition (OR 1.48). The increase in the OR of the use of Chinese herbs and traumatology manipulative therapy according to the number of chronic conditions was not as substantial as that of acupuncture-moxibustion. The frequency of TCM use exhibited an increasing trend with the increase in the number of chronic conditions (pherbs use, traumatology manipulative therapy use, and, particularly, acupuncture-moxibustion use increased as the number of chronic conditions increased. We suggest that government policy makers emphasize administering integrated TCM and WM care to people with chronic conditions or MCC.

Guibi-tang (Guipi-tang in Chinese and Kihi-to in Japanese) is a multi-herb traditional medicine commonly prescribed to treat psychoneurosis in East Asia. Although this medicine has been widely used, there is little available information on the safety and toxicity of Guibi-tang, especially on the fermented one. Guibi-tang, composed of 12 herbs, was fermented with bacteria and lyophilized. Single dose acute toxicity in rats was observed for 14 days after administration. Genetic toxicity of fermented Guibi-tang was evaluated on bacterial reverse mutation in Salmonella and Escherichia spp., chromosome aberrations in Chinese hamster ovary cells, and micronucleus formation in mice. Ingredients in FGBT were identified and quantified by high performance liquid chromatography-mass spectrometry. In acute oral toxicity study, behavior, clinical signs and body weight changes were normal observing in all experimental animals. No revertant colonies were found in any bacterial cultures examined. Morphological or numerical anomalies and significant increased number of aberrant metaphases were not observed. Micronucleus assay showed no significant increases in the frequency of inducing micronuclei in any dose examined. Decursinol, decursin, glycyrrhizin, and 6-gingerol in fermented Guibi-tang were identified and quantitated. As a whole, no acute and genotoxic effects were found in all the assays and parameters analyzed. Fermented Guibi-tang was recognized as safe and non-toxic, and therefore can be used for applications of traditional medicine in modern complementary and alternative therapeutics and health care.

Background Traditional Chinese medicine (TCM) has remained an integral part of Chinese culture and society for thousands of years. In Taiwan TCM is a recognized element of its National Health Insurance Scheme. However, there is no knowledge about how TCM is accessed by foreign workers from a non-Asian cultural background. The objectives of this study were to investigate the prevalence and patterns of TCM use among non-Asian white-collar workers living in Taiwan, and examine factors likely to influence their use of TCM. Methods This study applied a cross-sectional survey design. A total of 207 white-collar foreign workers of a non-Asian background currently holding National Health Insurance cards who had lived in Taiwan for 4 months or more participated in this study. Results The prevalence of TCM use was 45%. The most frequently used therapies were traditional Chinese herbs/medicine and acupuncture. Factors indicating the likelihood of TCM usage were age 31–40 years, visit to an allopathic medical doctor in the last year, ability to read Chinese, having a friend or family member available to assist in the use of TCM, and access to information about TCM services available in Taiwan. Conclusion Utilization of TCM by people of a non-Asian background living in Taiwan appears to be most influenced by enabling factors including language ability, access to information, and informal reference persons.

Full Text Available Abstract The use of herbs as ergogenic aids in exercise and sport is not novel. Ginseng, caffeine, ma huang (also called 'Chinese ephedra', ephedrine and a combination of both caffeine and ephedrine are the most popular herbs used in exercise and sports. It is believed that these herbs have an ergogenic effect and thus help to improve physical performance. Numerous studies have been conducted to investigate the effects of these herbs on exercise performance. Recently, researchers have also investigated the effects of Eurycoma longifolia Jack on endurance cycling and running performance. These investigators have reported no significant improvement in either cycling or running endurance after supplementation with this herb. As the number of studies in this area is still small, more studies should be conducted to evaluate and substantiate the effects of this herb on sports and exercise performance. For instance, future research on any herbs should take the following factors into consideration: dosage, supplementation period and a larger sample size.

Traditional Chinese Medicine for Senile Dementia

Directory of Open Access Journals (Sweden)

Zhihong Lin

2012-01-01

Full Text Available Traditional Chinese Medicine (TCM has a 3000 years' history of human use. A literature survey addressing traditional evidence from human studies was done, with key result that top 10 TCM herb ingredients including Poria cocos, Radix polygalae, Radix glycyrrhizae, Radix angelica sinensis, and Radix rehmanniae were prioritized for highest potential benefit to dementia intervention, related to the highest frequency of use in 236 formulae collected from 29 ancient Pharmacopoeias, ancient formula books, or historical archives on ancient renowned TCM doctors, over the past 10 centuries. Based on the history of use, there was strong clinical support that Radix polygalae is memory improving. Pharmacological investigation also indicated that all the five ingredients mentioned above can elicit memory-improving effects in vivo and in vitro via multiple mechanisms of action, covering estrogen-like, cholinergic, antioxidant, anti-inflammatory, antiapoptotic, neurogenetic, and anti-Aβ activities. Furthermore, 11 active principles were identified, including sinapic acid, tenuifolin, isoliquiritigenin, liquiritigenin, glabridin, ferulic acid, Z-ligustilide, N-methyl-beta-carboline-3-carboxamide, coniferyl ferulate and 11-angeloylsenkyunolide F, and catalpol. It can be concluded that TCM has a potential for complementary and alternative role in treating senile dementia. The scientific evidence is being continuously mined to back up the traditional medical wisdom.

Community structure is one of the most important properties in networks, in which a node shares its most connections with the others in the same community. On the contrary, the anti-community structure means the nodes in the same group have few or no connections with each other. In Traditional Chinese Medicine (TCM), the incompatibility problem of herbs is a challenge to the clinical medication safety. In this paper, we propose a new anti-community detection algorithm, Random non-nEighboring nOde expansioN (REON), to find anti-communities in networks, in which a new evaluation criterion, anti-modularity, is designed to measure the quality of the obtained anti-community structure. In order to establish anti-communities in REON, we expand the node set by non-neighboring node expansion and regard the node set with the highest anti-modularity as an anti-community. Inspired by the phenomenon that the node with higher degree has greater contribution to the anti-modularity, an improved algorithm called REONI is developed by expanding node set by the non-neighboring node with the maximum degree, which greatly enhances the efficiency of REON. Experiments on synthetic and real-world networks demonstrate the superiority of the proposed algorithms over the existing methods. In addition, by applying REONI to the herb network, we find that it can discover incompatible herb combinations.

Chang-Kang-Fang formula (CKF), a multi-herb traditional Chinese medicinal formula, has been clinically used for treatment of irritable bowel syndrome (IBS). The mechanisms of CKF for treating IBS and the components that are responsible for the activities were still unknown. To investigate the chemical profiles and effects of CKF on IBS model. The chemical profiles of CKF were investigated by ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q/TOF-MS/MS). On colon irritation induced rat neonates IBS model, the influence of CKF on neuropeptides, including substance P (SP), calcitonin gene-related peptide (CGRP), vasoactive intestinal polypeptide (VIP) and 5-hydroxytryptamine (5-HT), were measured by ELISA, and the effect on intestinal sensitivity was assessed based on the abdominal withdrawal reflex (AWR) scores. In addition, the activities of CKF against acetic acid-induced nociceptive responses and prostigmin methylsulfate triggered intestinal propulsion in mice were also evaluated. 80 components were identified or tentatively assigned from CKF, including 11 alkaloids, 20 flavanoids, 4 monoterpenoids, 9 iridoid glycoside, 9 phenylethanoid glycosides, 10 chromones, 7 organic acid, 3 coumarins, 2 triterpene and 5 other compounds. On IBS rat model, CKF was observed to reduce AWR scores and levels of SP, CGRP, VIP and 5-HT. Moreover, CKF reduced the acetic acid-induced writhing scores at all dosages and reduced the intestinal propulsion ration at dosage of 7.5 and 15.0g/kg/d. CKF could alleviate the symptoms of IBS by modulating the brain-gut axis through increasing the production of neuropeptides such as CGRP, VIP, 5-HT and SP, releasing pain and reversing disorders of intestinal propulsion. Berberine, paeoniflorin, acteoside, flavonoids and chromones may be responsible for the multi-bioactivities of CKF. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

Seahorse documented in Chinese pharmacopeia possess important medicinal efficacy and are used as an ingredient in traditional Chinese medicines. The growing international trade threatens the species. DNA barcoding holds a great application potentiality in wildlife conservation and might prevent the illegal trade of threatened species. The COI gene was used to identify seahorse, and nine Hippocampus species were found in the three large traditional Chinese medicines markets of China. All inter-specific genetic variations were larger than 2%. Mean genetic distances between species were 17-fold larger than those within the species. Phylogenetic tree showed that each species clustered in the appropriate branch. All results demonstrated that COI-based barcoding technique could be used to identify seahorse species and played a major role in monitoring the seahorse trade.

The traditional sulfur fumigation processing method has been widely used in the initial processing and storage of traditional Chinese medicinal materials due to its economy, efficiency, convenience, high operability and effect on mold and insect prevention. However, excessive sulfur fumigation of traditional Chinese medicinal materials would lead to the changes in chemical compositions, and even endanger human health. This study showed that traditional Chinese medicinal materials were sulfur fumigated directly after being harvested for quick drying, or fumigated after being weted in the storage process for preventing mold and insects. We found that the sulfur dioxide limits for traditional Chinese medicinal materials were stricter than those for foods. Based on the existing limit standards, we obtained the data of sulfur dioxide residues for 35 types of traditional Chinese medicinal materials in a total of 862 batches. According to the limit standard in the Chinese Pharmacopoeia (150， 400 mg·kg⁻¹), the average over-standard rate of sulfur dioxide was as high as 52.43%, but it was reduced to 29.47% if calculated based on the limit for vegetable additive standard (500 mg·kg⁻¹). Sulfur fumigation issue shall be considered correctly: sulfur dioxide is a type of low toxic substance and less dangerous than aflatoxin and other highly toxic substances, and a small amount of residue would not increase the toxicity of traditional Chinese medicinal materials. However, sulfur fumigation might change the content of chemical substances and affect the quality of traditional Chinese medicinal materials. Furthermore, the exposure hazards of toxic substances are comprehensively correlated with exposure cycle, exposure frequency, and application method. In conclusion, it is suggested to strengthen the studies on the limit standard of traditional Chinese medicinal materials, formulate practical and feasible limit standard for sulfur dioxide residues in traditional Chinese

To study the anti-Coxsackie B virus (CVB3m) action of Chaihu(XCT) and its decomposed herb soups No.1 and No.2 in vitro, and also their protective effect on cells. The anti CVB3m and cell protection effects of XCT and its decomposed herb soups No.1 and No.2 were observed by the methods of micro-cell culture and neutral red ingestion, taking cytopathic effect and cell activity as judgments of medicine toxicity and virus replication. The non-toxic concentrations of XCTand its decomposed herb soups No.1 and No.2 had no apparent influence on HeLa cell activity, on the contrary, in certain range of concentrations, they could promote cell growth and cell activity. In therapeutic cell group, XCT and its decomposed herb soups No.1 and No.2 all had apparent inhibitory effect on CVB3m replication, especially the decomposed No.1 showing an inhibitory rate of 107.6%. Under the same decomposed No.1 concentration(1.5 mg/ml), the viral inhibitory rate of the preventive therapeutic cell group was much higher than that of the therapeutic cell group, reaching as high as 128.1%. In virus adsorbed cell group, the CVB3m was also obviously inhibited by the XCT and decomposed No.1 and No.2. By comparing the effects on cell protection and virus replication of XCT and its decomposed herb soups No.1 and No.2, it identifies that XCT can protect cells against virus infection and directly kill the CVB3m, this Chinese herb medicine may be applied clinically for preventing and curing of viral myocarditis.

Many patients with gynecological disorders seek traditional medicine consultations in Asian countries. This study intended to investigate the utilization of traditional Chinese medicine (TCM) in patients with dysfunctional uterine bleeding (DUB) in Taiwan. We analyzed a cohort of one million individuals randomly selected from the National Health Insurance Research Database in Taiwan. We included 46,337 subjects with newly diagnosed DUB (ICD-9-CM codes 626.8) from January 1, 1997 to December 31, 2010. The patients were categorized into TCM seekers and non-TCM seekers according to their use of TCM. Among the subjects, 41,558 (89.69%) were TCM seekers and 4,779 (10.31%) were non-TCM seekers. Patients who were younger tended to be TCM seekers. Most of the patients had also taken Western medicine, especially tranexamic acid and non-steroidal anti-inflammatory drugs (NSAIDs). More than half of TCM seekers (55.41%) received combined treatment with both Chinese herbal remedies and acupuncture. The most commonly used TCM formula and single herb were Jia-Wei-Xiao-Yao-San (Bupleurum and Peony Formula) and Yi-Mu-Cao (Herba Leonuri), respectively. The core pattern of Chinese herbal medicine for DUB patients consisted of Jia-Wei-Xiao-Yao-San, Xiang-Fu (Rhizoma Cyperi), and Yi-Mu-Cao (Herba Leonuri). TCM use is popular among patients with DUB in Taiwan. Further pharmacological investigations and clinical trials are required to validate the efficacy and safety of these items.

Hepatotoxicity or hepatoprotection? Pattern recognition for the paradoxical effect of the Chinese herb Rheum palmatum L. in treating rat liver injury.

Jia-bo Wang

Full Text Available The hepatotoxicity of some Chinese herbs has been a cause for concern in recent years. However, some herbs, such as rhubarb, have been documented as having both therapeutic and toxic effects on the liver, leading to the complex problem of distinguishing the benefits from the risks of using this herb. To comparatively analyze the dose-response relationship between rhubarb and hepatic health, we administrated total rhubarb extract (RE to normal and carbon tetrachloride (CCl(4-treated rats for 12 weeks at 4 dosage levels (2.00, 5.40, 14.69 and 40.00 g·kg(-1, measured as the quantity of crude material, followed by biochemical and histopathological tests of the rats' livers. A composite pattern was extracted by factor analysis, using all the biochemical indices as variables, into a visual representation of two mathematically obtained factors, which could be interpreted as the fibrosis factor and the cellular injury factor, according to the values of the variable loadings. The curative effect of administering the two lowest dosages of RE to CCl(4-treated rats was mainly expressed as a decrease in the extent of cellular injury. The hepatoprotective mechanism of RE might be related to its antioxidant effect, the antagonism of the free radical damage to hepatocytes caused by CCl(4. By contrast, the RE-induced liver damage was mainly expressed as a significant increase in the amount of fibrosis in both normal rats at all dosage levels and CCl(4-treated rats at the two highest dosage levels. Therefore, the hepatotoxic potential of RE could be attributable to the liver cell fibrosis induced by high doses of the herb. This study illustrates the bidirectional potential of rhubarb and demonstrates the feasibility of using factor analysis to study the dose-response relationships between herbal medicines and hepatotoxicity or the healing effects of these herbs by extracting the underlying interrelationships among a number of functional bio-indices in a holistic

The pharmacological activity of active ingredients from Chinese medicine depends greatly on the microecological environment of probiotics in the human body. After effective ingredients from traditional Chinese medicines are metabolized or biotransformed by probiotics, their metabolites can increase pharmacological activity, and can be absorbed more easily to improve the bioavailability. Therefore, the combination of Chinese medicines with probiotics is the innovation point in R&D of functional food and Chinese medicines, and also a new thinking for the modernization of Chinese medicine.This review summarizes and analyses the research progress on metabolism effects of gut microbiota on Chinese medicines components, the regulating effect of effective ingredients from Chinese medicine on intestinal probiotics, the application status of probiotics in traditional Chinese medicines, and the main problems and prospects in the research and development of Chinese medicines products with probiotic, aiming to provide theoretical guidance and practical value for the fermentation engineering of Chinese herbal medicine.

To respond to the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in China, the integration of antiretroviral therapy (ART) and traditional Chinese medicine (TCM) has important implications in health outcomes, especially in China where the use of TCM is widespread. The National Free TCM Pilot Program for HIV Infected People began in 5 provinces (Henan, Hebei, Anhui, Hubei, and Guangdong) in 2004, and quickly scaled up to 19 provinces, autonomous regions, and municipalities in China including some places with high prevalence, 26,276 adults have been treated thus far. Usually, people with HIV infection seek TCM for four main reasons: to enhance immune function, to treat symptoms, to improve quality of life, and to reduce side effects related to medications. Evidences from randomized controlled clinical trials suggested some beneficial effects of use of traditional Chinese herbal medicine for HIV infections and AIDS. More proofs from large, well-designed, rigorous trials is needed to give firm support. Challenges include interaction between herbs and antiretroviral drugs, stigma and discrimination. The Free TCM Program has made considerable progress in providing the necessary alternative care and treatment for HIV-infected people in China, and has strong government support for continued improvement and expansion, establishing and improving a work mechanism integrating Chinese and Western medicines.

In recent years, more and more research shows that the pharmacokinetic parameter of traditional Chinese medicine can be affected by the disease states. It's possible that drug metabolic enzymes, transporters, cell membrane permeability and the change of microbes group could be interfered with physiological and pathological changes, which enables the pharmacokinetics of traditional Chinese medicine in the body to be altered, including the process of absorption, distribution, metabolism and excretion, and then the pharmacokinetic parameters of traditional chinese medicine are altered. It's found that investigating the pharmacokinetic of traditional Chinese medicine in the pathological state is more useful than that of in normal state because the great part of traditional Chinese medicine is mainly used to treat disease. This article reflects the latest research on the pharmacokinetic of traditional Chinese medicine in the disease state such as diabete, cerebral ischemia, liver injury, inflammatory disease, nervous system disorders and fever in order to provide certain reference for clinicians designing reasonable administration dose.

Both chemical drugs and traditional Chinese medicines have the problem of low bioavailability. However, as traditional Chinese medicines are a multi-component complex, their dosage forms are required to be designed in line with their characteristics, in order to improve the bioavailability of traditional Chinese medicines. Traditional Chinese medicines are mostly prepared into pill, powder, paste, elixir and decoction, but with such drawbacks as high administration dose and poor efficacy. With the process of modernization of traditional Chinese medicines, new-type preparations have be developed and made outstanding achievements. However, they fail to make an organic integration between traditional Chinese medicine theories and modern preparation theories. Characteristics of traditional Chinese medicines are required to be taken into account during the development of traditional Chinese medicines. In the article, multi-component preparation technology was adopted to establish a multi-component drug release system of traditional Chinese medicines on the basis of multiple components of traditional Chinese medicines.

A study was carried out to find the effect of γ-irradiation on contents of volatile compounds from medicinal herb, Paeoniae Radix (Paenia albiflora Pallas var. trichocarpa Bunge). The volatile compounds of control, 1, 3, 5 and 10 kGy irradiated samples were extracted by simultaneous steam distillation and extraction (SDE) method and analyzed by gas chromatograph-mass spectrometer. The major volatile compounds were paeonol, (E)-carveol, (E,E)-2,4-octadienal, methyl salicylate, myrtanol and eugenol acetate. Volatile compounds belonging to chemical classes of acids, alcohols, aldehydes, esters, hydrocarbons and miscellaneous were identified in all experimental samples. The types of volatile compounds in irradiated samples were similar to those of non-irradiated sample and the concentrations of these compounds differed between treatments. 1,3-Bis (1,1-dimethylethyl)-benzene was identified by using the selected ion monitoring (GC/MS-SIM) mode. The concentration of this compound increased with the increase of irradiation dose level. These results suggest that it could be used as the base data for the effect of γ-irradiation on medicinal herb.

2017-10-05

The purpose of this review was to create an online research summary table of heart toxicity case reports related to dietary supplements (DS; includes herbs). Documented PubMed case reports of DS appearing to contribute to heart-related problems were used to create a "Toxic Table" that summarized the research (1966 to April, 2016, and cross-referencing). Keywords included "herb," "dietary supplement," and cardiac terms. Case reports were excluded if they were herb combinations (some exceptions), Chinese herb mixtures, teas of mixed herb contents, mushrooms, poisonous plants, self-harm (e.g. suicide), excess dose (except vitamins/minerals), drugs or illegal drugs, drug-herbal interactions, and confounders of drugs or diseases. The spectrum of heart toxicities included hypertension, hypotension, hypokalemia, bradycardia, tachycardia, arrhythmia, ventricular fibrillation, heart attack, cardiac arrest, heart failure, and death. Heart related problems were associated with approximately seven herbs: Four traditional Chinese medicine herbs - Don quai (Angelica sinensis), Jin bu huan (Lycopodium serratum), Thundergod vine or lei gong teng (Tripterygium wilfordii Hook F), and Ting kung teng (Erycibe henryi prain); one an Ayruvedic herb - Aswagandha, (Withania somnifera); and two North American herbs - blue cohosh (Caulophyllum thalictroides), and Yohimbe (Pausinystalia johimbe). Aconitum and Ephedra species are no longer sold in the United States. The DS included, but are not limited to five DS - bitter orange, caffeine, certain energy drinks, nitric oxide products, and a calming product. Six additional DS are no longer sold. Licorice was the food related to heart problems. The online "Toxic Table" forewarns clinicians, consumers and the DS industry by listing DS with case reports related to heart toxicity. It may also contribute to Phase IV post marketing surveillance to diminish adverse events that Government officials use to regulate DS.

The essential traditional Chinese medicines (ETCM) are the characteristics of our National Essential Medicine List (NEML) and we should give full play to its unique advantage. The essential medicines of ETCM are specific, but also have dual characters, namely efficacy and ADRs. Although ADRs cannot be avoided, we can make efforts to control some conditions to minimize the possibility of ADRs. It is significant to give suggestions to reduce ADRs of ETCM under the ETCM system by analyzing the possibility of ADRs during ETCM selection, production distribution and use. This research focuses on ETCM, and the conclusion is also applicable to common traditional Chinese medicines. Copyright© by the Chinese Pharmaceutical Association.

Infestation, moldy and other phenomenon in the processing and storage of Chinese herbal medicines is a problem that faced in the production of Chinese traditional medicine. The low productivity of traditional processing methods can not guarantee the quality of Chinese herbal medicines. Sulfur fumigation is the first choice of grassroots to process the Chinese herbal medicine with its low cost and easy operation. Sulfur fumigation can solve some problems in the processing and storage of Chinese herbal medicines, but modern pharmacological studies show that long-term use of Chinese traditional medicine which is fumigated by sulfur can cause some serious harm to human liver, kidney and other organs. This paper conducts a review about the application history of sulfur fumigation, its influence to the quality of Chinese herbal medicines as well as domestic and foreign limits to sulfur quantity, and a brief introduction of the status of modern processing technologies in the processing of food and some Chinese herbal medicines, the problems ex- isting in the Chinese herbal medicines processing, which can provide a reference basis for the further research, development and application of investigating alternative technologies of sulfur fumigation.

Acupuncture in Chinese medicine has been a treasure in Chinese traditional medicine for thousands of years. It is opposite to many basic theories in modern medicine in dynasties. Different from the cross compatibility and interactions among medical medicines, acupuncture in Chinese medicine has its own consolidation and inherent philosophical ideas. In view of this, how to discuss the philosophical ideas and its development of acupuncture in Chinese medicine becomes of great importance. It is crucial to clearly answer the three theoretical propositions in the development of acupuncture in Chinese medicine. Firstly, the differences in acupuncture should be identified between the ancient time and the modern time. The issues focus on the origin of Huangdi Neijing ( Yellow Emperor's Internal Medicine ) and its philosophical divergence. Secondly, the origin of acupuncture should be identified, whether it is from China or India. Thirdly, the differences in acupuncture should be identified between China and the west, focusing on the explanation and rectification of the interrelationship between the acupuncture in Chinese medicine and the western acupuncture. Hence, the basic features are discussed on the reality of acupuncture in Chinese medicine as well as its diversity. Finally, the proposition is extended on how to holistically grasp the philosophical foundation of acupuncture in Chinese medicine and its future trend.

Chemiluminescence, electron spin resonance, thermoluminescence and viscosity measurements have been investigated for their suitability as detection method for the irradiation of the medicinal herbs anise seeds (anisi fructus), valerian roots (valerianae radix), redberry leaves (uvae ursi folium), birch leaves (betulae folium), greek hay seeds (foenugraeci semen), cayenne pepper (capsici fructus acer), black-aldertee bark (frangulae cortex), fennel fruits (feoniculi fructus), rose hip shells (cynosbati fructus), coltsfoot (farfarae folium), acorus roots (calami rhizoma), chamomile flowers (matricariae flos), caraway (carvi fructus), lavender flowers (lavandulae flos), linseed (lini semen), lime tree flowers (tiliae flos), St. Mary's thistle fruit (cardui mariae herba), lemon balm (melissae folium), java tea (orthosiphonis folium), peppermint (menthae piperitae folium), sage leaves (salviae folium), scouring rush (equiseti herba), senna leaves (sennae folium), plantain herbs (plantaginis lanceolata herba), thyme herbs (thymi herba), juniper berries (juniperi fructus), hawthorne herbs (crataegi folium), wheat starch (amylum tritici) and wormwood (absinthii herba). Depending on the herbs, the methods used were more or less suitable. Chemiluminescence measurements showed the smallest differences between untreated and irradiated samples whereas thermoluminescence measurements on isolated minerals from the vegetable drugs gave better results. In some herbs radiation-specific radicals could be identified by ESR spectroscopy. Viscosity measurement is suitable for some herbs as fast and inexpensive method for screening. (orig.) [de

In order to provide theoretical clues and data support for the use of Chinese medicine clinical drug, experimental study of Chinese materia medica and development of new resources of Chinese materia medica, the four properties as the core, the relationships of property, flavor, channel tropism and toxicity in nature data of Chinese materia medica were analyzed. The spearman rank correlation method was employed to analyze 8 356 Chinese drugs with characteristic of four properties from " Chinese Herbal Medicine" based on data level coding. It was discovered that four properties showed significant positive correlations with tastes of "pungent and sweet" , channels of "spleen" , "stomach" , "kidney" and "toxicity" , but also showed significant negative correlations with tastes of "bitter" and "light" and six channels such as "large intestine" , "heart", "bladder" , "gallbladder" , "small intestine" and "lung" (in descending order of correlation ) (P <0. 01). It was indicated that the more hot the Chinese medicine nature, the more possible it contained "toxicity" , tastes of "pungent" and "sweet" , and the more possible it was belong to channels of "spleen" , "stomach" and "kidney". As well, the more cold the Chinese medicine nature, the more possible it contained tastes of "bitter" and "light", and the more possible it was belong to six channels such as "large intestine", etc.

Catalytic Therapy of Cancer with Ascorbate and Extracts of Medicinal Herbs

2010-01-01

Full Text Available Catalytic therapy (CT is a cancer treatment modality based on the generation of reactive oxygen species (ROS using a combination of substrate molecules and a catalyst. The most frequently used substrate/catalyst pair is ascorbate/Co phthalocyanine (PcCo. In the present work, herb extracts containing pigments have been studied as a catalyst in place of PcCo. Extracts from herbs are expected to have efficiency comparable with that of phthalocyanines but as natural products, to exhibit fewer side effects. The present studies demonstrate that a combined use of ascorbate and herbal extracts results in ROS production and a significant decrease in the number of cancer cells after a single in vitro treatment. Treatment with ascorbate in conjunction with extracts prepared from several medicinal herbs stimulated apoptosis and disrupted the cell cycle. The number of cells accumulating in the sub-G0/G1 stage of the cell cycle was increased 2- to 7-fold, and cells in G2/M increased 1.5- to 20-fold, indicating that the treatment protocol was highly effective in suppressing DNA synthesis and potentially reflecting DNA damage in the tumor cells. In addition, 20–40% of the cells underwent apoptosis within 24 h of completing treatment. Our results suggest that herbal extracts can function as CT catalysts in the treatment of cancer.

On the road of the modern Chinese medicine developing internationally, there is a key issues that setting up a reasonable, accurate and be quantified quality evaluation system which is comply with the basic theory of Chinese medicine. Based on the overall understanding of the role of traditional Chinese medicine components, author suggested that the idea of "structural components" theory should be embedded into the system and thought the Chinese medicine play a multi-target, multi-channel pharmacodynamic effects founded on the specific microcosmic structural relationship between the components and the components within the group. At present, the way of Chinese pharmacopoeia checking the quality of Chinese medicine is mainly depends on controlling the single or multiple targets of ingredients. In fact, this way is out of the overall effectiveness of the Chinese medicine, so we can not thoroughly controlling the quality of Chinese medicine from the essence of the Chinese medicine. Secondly, it's only macro-structural quantity that the Chinese pharmacopoeia just controlling the less effective ingredients, this is not enough to reflect the internal microstructure of the integrity and systematic. In other words, this cannot reflect the structural components of the Chinese medicine (the essence of traditional Chinese medicine). In view of above mentioned reasons, the author propose the new idea on the quality control in the medicine that quantify the ratio structural relationship in component and the ingredients of the components, set the optimal controlling proportion between the components and ingredients. At the same time, author thought we should conduct the depth study in the micro-quantified the multi-component and multi-ingredient, in the process of studying the material basis of Chinese medicine. Therefore, it could establish a more rational basis for the Chinese medicine quality controlling system.

Chinese medicine is known to treat complex diseases with multiple components and multiple targets. However, the main effective components and their related key targets and functions remain to be identified. Herein, a network analysis method was developed to identify the main effective components and key targets of a Chinese medicine, Lianhua-Qingwen Formula (LQF). The LQF is commonly used for the prevention and treatment of viral influenza in China. It is composed of 11 herbs, gypsum and menthol with 61 compounds being identified in our previous work. In this paper, these 61 candidate compounds were used to find their related targets and construct the predicted-target (PT) network. An influenza-related protein-protein interaction (PPI) network was constructed and integrated with the PT network. Then the compound-effective target (CET) network and compound-ineffective target network (CIT) were extracted, respectively. A novel approach was developed to identify effective components by comparing CET and CIT networks. As a result, 15 main effective components were identified along with 61 corresponding targets. 7 of these main effective components were further experimentally validated to have antivirus efficacy in vitro. The main effective component-target (MECT) network was further constructed with main effective components and their key targets. Gene Ontology (GO) analysis of the MECT network predicted key functions such as NO production being modulated by the LQF. Interestingly, five effective components were experimentally tested and exhibited inhibitory effects on NO production in the LPS induced RAW 264.7 cell. In summary, we have developed a novel approach to identify the main effective components in a Chinese medicine LQF and experimentally validated some of the predictions.

In this study, the concentrations and types of the antioxidant compounds of eight Chinese herbal medicines, which have previously demonstrated promising effects on suppressing heat stress as a mixture, were investigated using reversed-phase High Performance Liquid Chromatography, spectrophotometry, Liquid Chromatography Mass Spectrometry, and Gas-Liquid Chromatography. Our results provided the levels of phenolic compounds, total amounts of sugars, and total unsaturated fatty acids in the herbal extracts. Apart from the detection and quantification of the active ingredients of herbs that have the potential to mitigate heat stress in poultry, results of this study also provide useful data for developing an efficient and accurate formulation of the herbs’ mixtures in order to induce positive effects against heat stress in in vivo studies.

The Transmission of Chinese Medicine in Australia

Directory of Open Access Journals (Sweden)

Mary Garvey

2011-12-01

Full Text Available The paper explores some of the issues concerning the transmission of Chinese medicine in Australia, its practitioner training and the future of Chinese medicine as a distinct medical discipline in the Australian context. In China over the last century Chinese medicine was overhauled in order to align it with the biomedical perspective prevalent in the West. These changes, in turn, had important consequences for the transmission of CM in Australia and the West. But while the biomedicalisation of CM has offered the path of least resistance, it has also lead to unworkable simplifications and methodological failures. The paper thus argues for a renewed access to the tradition’s primary sources in order to ally the distinctive features and methods of traditional practice with biomedicine, as an alternative to an outright integration into biomedical practice.

Metabolomics provides an opportunity to develop the systematic analysis of the metabolites and has been applied to discovering biomarkers and perturbed pathways which can clarify the action mechanism of traditional Chinese medicines (TCM). TCM is a comprehensive system of medical practice that has been used to diagnose, treat and prevent illnesses more than 3000 years. Metabolomics represents a powerful approach that provides a dynamic picture of the phenotype of biosystems through the study of endogenous metabolites, and its methods resemble those of TCM. Recently, metabolomics tools have been used for facilitating interactional effects of both Western medicine and TCM. We describe a protocol for investigating how metabolomics can be used to open up 'dialogue' between Chinese and Western medicine, and facilitate lead compound discovery and development from TCM. Metabolomics will bridge the cultural gap between TCM and Western medicine and improve development of integrative medicine, and maximally benefiting the human.

To explore advantages of Chinese medicine (CM) by analyzing differences in the origin of philosophy for human health between CM and Western medicine (WM). Methodologically, a distinctive feature of CM is its systems theory, which is also the difference between CM and WM. Since the birth of CM, it has taken the human body as a whole from the key concepts of "qi, blood, yin-yang, viscera (Zang-Fu), and meridian and channel", rather than a single cell or a particular organ. WM evolves from the Western philosophic way of thinking and merely uses natural sciences as the foundation. The development of WM is based on human structures, or anatomy, and therefore, research of WM is also based on the way of thinking of decomposing the whole human body into several independent parts, which is the impetus of promoting the development of WM. The core of CM includes the holistic view and the dialectical view. Chinese herbal medicines contain various components and treat a disease from multiple targets and links. Therefore, Chinese herbal medicines treat a diseased state by regulating and mobilizing the whole body rather than just regulating a single factor, since the diseased state is not only a problem in a local part of the body but a local reflection of imbalance of the whole body.

2016-01-01

Background. Chinese herbal medicines reportedly increase efficacy and minimize toxicity of chemotherapy; however, little attention has been paid to how poor study quality can bias outcomes. Methods. We systematically searched MEDLINE, TCMLARS, EMBASE, and Cochrane Library for randomized controlled trials of Chinese herbal medicines combined with fluorouracil-based chemotherapy compared with the same chemotherapy alone. We screened for eligibility, extracted data, and pooled data with random-effects meta-analysis. Outcome measures were survival, toxicity, tumor response, performance status, quality of life, and Cochrane Risk of Bias (ROB) criteria to critically evaluate the quality of reporting in the randomized trials included in the meta-analysis. Results. We found 36 potentially eligible studies, with only 3 (those with low ROB) qualifying for meta-analysis. Two reported chemotherapy-related diarrhea reduced by 57% (relative risk [RR] = 0.43; 95% CI = 0.19-1.01; I2 test for variation in RR due to heterogeneity = 0.0%), with nonsignificant results. Two reported white blood cell toxicity reduced by 66% (RR = 0.34; 95% CI = 0.16-0.72; I2 test for variation in RR due to heterogeneity = 0.0%), with statistically significant results. Stratifying analysis by studies with high versus low ROB, we found substantial overestimation of benefit: Studies with high ROB overestimated by nearly 2-fold reduction of platelet toxicity by Chinese herbal medicines (RR = 0.35, 95% CI = 0.15-0.84 vs RR = 0.65, 95% CI = 0.11-3.92). Studies with high ROB overestimated by nearly 2-fold reduction of vomiting toxicity (RR = 0.45, 95% CI = 0.33-0.61 vs RR = 0.87, 95% CI = 0.48-1.58). And, studies with high ROB overestimated by 21% the reduction in diarrhea toxicity (RR = 0.34, 95% CI = 0.20-0.58 vs RR = 0.43, 95% CI = 0.19-1.01). Studies with high ROB also overestimated by 16% improvement in tumor response (RR = 1.39, 95% CI = 1.18-1.63 vs RR = 1.20; 95% CI = 0.81-1.79). Not accounting for ROB

2012-01-01

Drugs based on herbs have become a common form of therapy as well as for prophylaxis because they are often perceived as being natural and therefore harmless. Today they are one of the hottest trends and most sought after in the field of nutrition or herbal therapeutics. As the use of complementary medicine grows, so does the knowledge that many compounds in common use not only have a significant effect on the body but may also interact with pharmaceuticals and also with other alternative products. Concurrent use of herbs with drugs may mimic, magnify, or oppose the effect of drugs leading to herb-drug interactions. Currently, there is very little information published on herb-herb or herb-drug interactions as compared to the use of herbs which is progressively growing across the world. Many reports of herb-drug interactions are sketchy and lack laboratory analysis of suspect preparations. Health-care practitioners should caution patients against mixing herbs and pharmaceutical drugs. The article reviews the recent literature on the adverse effects of herbal remedies including the most widely sold herbal medicinal products, like liquorice, garlic, ginger, green tea, and turmeric, etc., and reinforce the safety aspect of herbal products, which are considered to be relatively safe by common people.

Traditional Chinese medicine has a long history in clinical application, and been proved to be safe and effective. In recent years, the toxicity and side-effects caused by the western medicine have been attracted much attention. As a result, increasing people have shifted their attention to traditional Chinese medicine. Nonetheless, due to the natural origin of traditional Chinese medicine and the lack of basic knowledge about them, many people mistakenly consider the absolute safety of traditional Chinese medicine, except for well-known toxic ones, such as arsenic. However, according to the clinical practices and recent studies, great importance shall be attached to the toxicity of non-toxic traditional Chinese medicine, in particular the hepatotoxicity. Relevant studies indicated that the toxicity of non-toxic traditional Chinese medicine is closely correlated with individual gene polymorphism and constitution. By discussing the causes and mechanisms of the hepatotoxicity induced by non-toxic traditional Chinese medicine in clinical practices, we wrote this article with the aim to provide new ideas for individualized clinical therapy of traditional Chinese medicine and give guidance for rational and safe use of traditional Chinese medicine.

With the completion of the human genome project, people have gradually recognized that the functions of the biological system are fulfilled through network-type interaction between genes, proteins and small molecules, while complex diseases are caused by the imbalance of biological processes due to a number of gene expression disorders. These have contributed to the rise of the concept of the "multi-target" drug discovery. Treatment and diagnosis of traditional Chinese medicine are based on holism and syndrome differentiation. At the molecular level, traditional Chinese medicine is characterized by multi-component and multi-target prescriptions, which is expected to provide a reference for the development of multi-target drugs. This paper reviews the application of network biology in traditional Chinese medicine in six aspects, in expectation to provide a reference to the modernized study of traditional Chinese medicine.

In recent years, the discovery and studies on aquaporin have made us have a more in-depth understanding about the physiological and pathological processes of water metabolism. Over years, however, there has been no quantitative study on the target sites of diuretic traditional Chinese medicines at the molecular level. In that case, aquaporin was found to been a new target molecule to explain the efficacy exertion of diuretic traditional Chinese medicines. By studying aquaporin, researchers can understand the implicit meaning of the diuretic effect of traditional Chinese medicines and conduct quantitative studies on the diuretic effect. So far, many scholars have conducted a series of studies in the traditional Chinese medicine field by using the findings on aquaporin and made certain advances. This article provides a summary about the efficacy exertion of diuretic traditional Chinese medicines through target molecule aquaporin.

Then, the MMP-AFB1-NP sandwich compounds were acquired, dehybridization of the oligonucleotides on the nanoparticle surface allows the determination of the presence of AFB1 by identifying the oligonucleotide sequence released from the NP through FQ-PCR detection. The bio-bar code techniques system for detecting AFB1 was established, and the sensitivity limit was about 10−8 ng/mL, comparable ELISA assays for detecting the same target, it showed that we can detect AFB1 at low attomolar levels with the bio-bar-code amplification approach. This is also the first demonstration of a bio-bar code type assay for the detection of AFB1 in Chinese herbs.

Dendrobium officinale is an important traditional Chinese herb. Here, we did a transcriptome-wide, organ-specific study on this valuable plant by combining RNA, small RNA (sRNA) and degradome sequencing. RNA sequencing of four organs (flower, root, leaf and stem) of Dendrobium officinale enabled us to obtain 536,558 assembled transcripts, from which 2,645, 256, 42 and 54 were identified to be highly expressed in the four organs respectively. Based on sRNA sequencing, 2,038, 2, 21 and 24 sRNAs were identified to be specifically accumulated in the four organs respectively. A total of 1,047 mature microRNA (miRNA) candidates were detected. Based on secondary structure predictions and sequencing, tens of potential miRNA precursors were identified from the assembled transcripts. Interestingly, phase-distributed sRNAs with degradome-based processing evidences were discovered on the long-stem structures of two precursors. Target identification was performed for the 1,047 miRNA candidates, resulting in the discovery of 1,257 miRNA--target pairs. Finally, some biological meaningful subnetworks involving hormone signaling, development, secondary metabolism and Argonaute 1-related regulation were established. All of the sequencing data sets are available at NCBI Sequence Read Archive (http://www.ncbi.nlm.nih.gov/sra/). Summarily, our study provides a valuable resource for the in-depth molecular and functional studies on this important Chinese orchid herb. PMID:26732614

Cardiovascular diseases (CVDs) have become prominent in mortality and morbidity rates. Prevalent cardiovascular conditions, such as hypertension, atherosclerosis and oxidative stress, are increasing at an alarming rate. Conventional drugs have been associated with adverse effects, suggesting a need for an alternative measure to ameliorate CVD. A number of plant- and herb-derived preventative food and therapeutic drugs for cardiovascular conditions are progressively used for their various benefits. Naturally derived food and drugs have fewer side effects because they come from natural elements; preventative food, such as grape seed, inhibits changes of histopathology and biomarkers in vital organs whereas therapeutic drugs, for instance Xanthone, improve heart functions by suppressing oxidative stress of myocyte. This review closely examines the various plant- and herb-derived drugs that have assumed an essential role in treating inflammation and oxidative stress for prevalent cardiovascular conditions. Furthermore, the use of plant-derived medicine with other synthetic particles, such as nanoparticles, for targeted therapy is investigated for its effective clinical use in the future.

Most of Chinese medicinal herbs are subjected to traditional processing procedures, including stir-frying, charring, steaming, boiling, and calcining before they are released into dispensaries. The marketing and identification of processed medicinal materials is a growing issue in the marketplace. However, conventional methods of identification have limitations, while DNA mini-barcoding, based on the sequencing of a short-standardized region, has received considerable attention as a new potential means to identify processed medicinal materials. In the present study, six DNA barcode loci including ITS2, psbA-trnH, rbcL, matK, trnL (UAA) intron and its P6 loop, were employed for the authentication of 45 processed samples belonging to 15 species. We evaluated the amplification efficiency of each locus. We also examined the identification accuracy of the potential mini-barcode locus, of trnL (UAA) intron P6 loop. Our results showed that the five primary barcode loci were successfully amplified in only 8.89%-20% of the processed samples, while the amplification rates of the trnL (UAA) intron P6 loop were higher, at 75.56% successful amplification. We compared the mini-barcode sequences with Genbank using the Blast program. The analysis showed that 45.23% samples could be identified to genus level, while only one sample could be identified to the species level. We conclude that trnL (UAA) p6 loop is a candidate mini-barcode that has shown its potential and may become a universal mini-barcode as complementary barcode for authenticity testing and will play an important role in medicinal materials control.
