RESUMEN
By reviewing the research history on quality comparison between wild and cultivated Chinese crude drugs， this paper systematically combed the relevant research reports since the 1950s， and summarized and analyzed the results of existing comparative studies， and found that the existing comparative research on the quality of wild and cultivated Chinese crude drugs were mainly focused on several aspects， including characteristics， microstructures， chemical compositions， pharmacodynamic effects， and genetic diversity. Among these， comparative studies of chemical compositions have been the dominant approach， with a particular emphasis on comparing the contents of index components. However， research on pharmacodynamic effects remained relatively limited. Due to various factors such as sample quantity， sample origin， growth period and cultivation methods， the differences in quality between wild and cultivated Chinese crude drugs vary significantly. In general， most wild Chinese crude drugs exhibited higher quality than cultivated products， with significant differences in their characteristics. The contents and proportions of some chemical components underwent noticeable changes， particularly with a marked increase in the proportion of primary metabolites after cultivation. The quality of cultivated Chinese crude drugs is closely related to the cultivation practices employed. Chinese crude drugs produced through wild nurturing， simulated wild planting， ecological cultivation， and other similar methods demonstrate quality levels comparable to those of wild Chinese crude drugs. Based on the analysis results， it is recommended to explicitly specify the cultivation practices and cultivation period of cultivated Chinese crude drugs in comparative studies of the quality between wild and cultivated Chinese crude drugs. Multiple technical approaches， including characteristics， microscopy， non-targeted metabolomics combined with quantitative analysis of differential components， and bioefficacy evaluation， should be employed to comprehensively assess the quality disparities between wild and cultivated Chinese crude drugs. Moreover， research efforts should be intensified to investigate the changes in pharmacodynamic effects resulting from differences in plant cell wall composition， primary metabolites， and secondary metabolites， in order to guide the production of high-quality Chinese crude drugs.
RESUMEN
Medicinal plants have been used in all cultures as a source of medicine since ages. When parts of plants such as rhizomes, leaves or barks and other natural materials are used as drugs to treat illnesses, they are called crude drugs and the study of crude drugs is called pharmacognosy. Proximate analysis in plants gives valuable information and help to assess the quality of a crude drug. Beneficial effects of crude drugs are believed to be attributed to plant phytochemicals. Hedychium coronarium J. Koenig, a medicinal and aromatic plant of high value is an endangered and red-listed plant. The rhizome of this plant is used for the treatment of various diseases. Crude extracts prepared from the rhizomes show antibacterial and antifungal properties. Essential oils obtained from Hedychium coronarium are found to be rich in terpenes and used for bactericidal, fungicidal, medicinal and cosmetic applications. The present study assesses the quality of crude drugs prepared from this highly medicinal plant. Proximate analysis and phytochemical screening of rhizomes of Hedychium coronarium, which is frequently consumed as food and as medicine were carried out. Ash content was found to be low) when compared to the moisture content. The water extractive value was more than alcohol extractive. Preliminary tests carried out on phytochemicals revealed the presence of terpenoids and oils. High Resolution Liquid Chromatography Mass Spectrophotometry was carried to ascertain the different components of essential oils and revealed the presence of eucalyptol (1,8-cineole), caryophyllene oxide, camphor, linoleic acid, ricinin, phloroglucinol, 6-gingerol, carvone and arjungenin.
RESUMEN
Ninety percent of the crude drugs consumed in Japan depend on imports. Recently, the Japanese government has been promoting the domestic production of crude drugs. We investigated the history and current situation of the cultivation of medicinal plants and the production of crude drugs in the Tohoku region, where the 71st annual meeting of the Japan Society for Oriental Medicine was held in August 2021. In the Tohoku region, the cultivation of medicinal plants expanded after the Kyoho era of the Edo period. Several medicinal plants in this region have been successfully cultivated and distributed as local specialty products and are being preserved (e.g., Panax ginseng in Aizu, Carthamus tinctorius in Dewa). In some other areas, cultivation has just begun. In each cultivation area, a contractual relationship was established in which local governments, cultivation experts, farmers, Kampo-related associations, and pharmaceutical companies collaborated to continue and expand the cultivation business. To generate revenue, they have been trying to find sales channels not only for crude drugs but also for foods, cosmetics, textiles, and processed products. Although many issues remain to be solved in the distribution of medicinal plants as the source of crude drugs, this survey clarified the ingenuity of medicinal plant cultivation in various areas of the Tohoku region. The results of the investigation are available as videos on the website for members of the Japan Society for Oriental Medicine.
RESUMEN
At the 71st Annual Meeting of the Japan Society for Oriental Medicine held in August 2021, we conducted a special program focusing on Kampo medicine education, “Pre-graduation post-graduation Kampo medicine education for the next generation.” The following is a summary report on the practical training in Kampo medicine at each educational facility where the project was conducted. We recorded videos with explanations of topics in advance : “Four examinations,” “Decoction and crude drugs,” and “Acupuncture and moxibustion.” The report on the hands-on training in Kampo medicine was viewed 501 times by medical students, educators, and the society members across the country. This initiative was the first nationwide educational activity of the society.
RESUMEN
The usage of Kampo medicine has been expanding in hospitals and pharmacies, and the systematic education on Kampo medicines and their components is urgently needed. Although the efficacies of Kampo formulations are approved at the national level, those of the composing crude drugs are not approved individually except for some cases. Consequently, the efficacy description of individual crude drug in textbooks differs much depending on the authors. To clarify this situation, we suggested the standardized description of the efficacy of crude drugs used in ethical Kampo formulation using terms of modern Western medicine in the previous study. In this study, we reviewed the descriptions of efficacies using the terms of Kampo medicine in the books published in Japan from the 17 century to the present to explore the possibility of standardizing the crude drug efficacies using the terms of Kampo medicine. The proposal for standardized description of the efficacy of crude drugs was based on the high frequency of appearance of the terms in successive books.
RESUMEN
Following the Chinese-led global standardization of Chinese medicine, the 9 th edition of the European Pharmacopoeia, published in 2016, listed 66 kinds of crude drugs that are used in traditional Chinese medicine. By the spread of dietary supplements in the United States, the number of herbal medicines listed in United States Pharmacopoeia is tended to be increasing. In this article, we compare the names and origins of crude drugs listed in the European and American Pharmacopoeias and used in ethical Kampo extract formulation with those described in the pharmacopoeias of Japan, China, Taiwan, and South Korea. There were 4 crude drugs that had the same origins and names in the pharmacopoeia of these 6 countries, but only Coix Seed had the same English name. The pharmacopoeia of the 5 countries except the United States had 19 crude drugs with the same origin, but only Platycodon Root and Eucommia Bark had the same English and Latin names. For other crude drugs, the names and origins in the pharmacopoeia of each country were different. When scientists in each country disseminate the information about crude drugs used in their own countries to the world, it is necessary for them to describe the original plant scientific names and their medicinal parts that are unified by International Code of Nomenclature for plants instead of English or Latin names of crude drugs.
RESUMEN
In recent years, in order to further improve the quality of decoction pieces of Chinese crude drugs, many related basic research work around the processing of decoction pieces of Chinese crude drugs have been carried out by relevant experts. Many opinions and suggestions on the revision of the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs were put forward. In order to further improve the preparation of the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs, strengthen the guidance on the revision of local processing standards, and clarify issues related to the circulation, use and supervision of decoction pieces, the Department of Drug Registration Management of the National Medical Products Administration and the Chinese Pharmacopoeia Commission have organized experts to discuss these problems. The author only puts forward some suggestions on related issues in order to achieve the purpose of "throwing a brick to attract jade". ①The study of the national regulations on the processing of decoction pieces of Chinese crude drugs should be standardized on the basis of the inheritance for the specific process. ②The revision of the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs should be improved on the basis of the existing research results. The regulation of the processing process should not be excessively parameterized, the revision of the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs also should be synchronization to the revision of the Chinese Pharmacopoeia. ③The contents of the Chinese Pharmacopoeia and the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs should have different emphasis. The former should focus on the standard, while the latter should focus on the processing process. ④The revision of local (provincial) processing specifications only collects the pieces that truly have local features and clinical characteristics. ⑤Decoction pieces of local Chinese crude drugs can only be applied at the place of production (province). They are allowed to be produced and distributed in other provinces, municipalities and autonomous regions after through filing. ⑥For the decoction pieces of Chinese crude drugs with large-scale use contained in local processing specifications, they should be included in the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs as soon as possible, and their quality standards should be included in the Chinese Pharmacopoeia.
RESUMEN
The treatment by Kampo decoction is partly covered by National Health Insurance in Japan. However, this system is facing bankruptcy crisis because of rising prices of crude drugs in China, their main producer. The board of crude drug materials of the Japan Society for Oriental Medicine (JSOM) distributed questionnaires to 7416 JSOM member doctors, and performed statistical analysis (with JSOM approval) of 1877 answers to visualize the data. Twenty-six percent of respondents said that they had prescribed a decoction, and 29% of respondents said they had not, but wanted to prescribe a crude drug. Eighty-eight percent of doctors who prescribe decoctions offered medical treatment primarily to insured patients. Nine percent offered medical treatment at patients' own expense. The latter group prescribed decoctions more frequently. Many doctors were aware of the financial risk of prescribing crude drugs imposed by the drug price standard and rising crude drug import prices. Four hundred and fifty-five doctors explained when they were most inclined to prescribe a decoction. Thirty-five percent of these said they used decoctions when they couldn't treat patients with extracts. This result implies a necessity for decoctions. Many doctors said they prescribed decoctions for autoimmune or allergic diseases. Financial constraints were the most frequently cited barrier to treatment with decoctions. This survey made clear the financial difficulties clinics are facing. We therefore calculated the amount of crude drugs used for decoctions to validate the possibility of their domestic production.
RESUMEN
We investigated the decocting time to prepare the formulas containing unprocessed aconite root, such as shigyakuto, tsumyaku shigyakuto, and kankyobushito, which had been registered in “Shanghanlun” edited in Song Dynasty, using the weights and measures in Houhan Dynasty when the original “Shanghanlun” was regarded to have been established. Also the contents of aconitine-type diester alkaloids (ADA) eluted from unprocessed aconite root in the decoction were analyzed in time-dependent manners. As regards the modified formula for the “physically strong patients” in the texts of tsumyakushigyakuto in “Shanghanlun”, adding dried ginger was found to lead the decocting time to be shorter and the sum of ADA content in the decoction of the modified formula to increase about 20%. It was also found that the compositions of diterpene alkaloids derived from aconite root in kankyobushito decoction were highly different from those in shigyakuto decoction, containing less ADA and more aconine and hypaconine, due to the high pH of the decoction, which was the consequence of lacking glycyrrhiza in kankyobushito formula. It is suggested that the doctors in the era of “Shanghanlun” establishment may have carefully adjusted the contents of ADA in the decoctions using unprocessed aconite root by choosing co-decocted crude drugs.
RESUMEN
Ayurveda is a system of Indian traditional form of alternative medicine. In 20th and 21th century due to side effects of synthetic drugs, there is an increasing interesting ASU medicine. At present the adulteration of the herbal drugs is the burning problem in ASU herbal industry and it has caused a major problem in the research on commercial natural products. The deforestation and extinction of many species and incorrect identification of many plants has resulted in adulteration and substitution of raw drugs. The future development of analysis of herbs is largely depended upon reliable methodologies for correct identification, standardization and quality assurance of Ayurvedic drugs. In India normally the contamination/adulteration in food/crude drugs is done either for financial gain or due to carelessness and lack in proper hygienic condition of processing, storing, transportation and marketing. Medicinal plants constitute an effective source of traditional and modern medicine. Adulteration is considered as an intentional addition of foreign substances to increase the weight of the product or to decrease its cost. It may be due to- Confusion in vernacular names, Lack of knowledge about authentic plants, Non availability, Similarity in morphology, activity, aroma, Careless collection and other unknown reasons. This article throws a light on adulteration, types, common market adulterants in ASU medicines and prescribed Prevention methods.
RESUMEN
Quantitative analysis of multi-components by single marker (QAMS) can be used to achieve the simultaneous determination of multiple components through a reference substance, which is considered suitable for the characteristics of Chinese materia medica (CMM). QAMS has been used for quality control of Chinese herbal medicines, Chinese herbal pieces, and CMM preparations. This paper briefly introduces the principle of QAMS method, and systematically summarizes the application of QAMS method in quality control of Chinese crude drugs, Chinese herbal pieces, and CMM preparation. Finally, it is proposed that active ingredients as an indicator component in QAMS is consistent with the multi-components characteristics of CMM, and it can be effectively used for quality control of CMM and has a good application prospect.
RESUMEN

Objective: To detect the differential expression profile of miRNAs (microRNAs) in crude drugs and processed products of Lycopodiastrum casuarinoides and identify potential bioactive herbal-derived miRNAs. Methods: The samples of the whole aerial tissues (including stems, leaves, branches) were collected in Yichun area of Jiangxi Province and were authenticated by relevant experts. General RNA was extracted from the crude drugs and processed products of L. casuarinoides, respectively. High-qualified small RNAs (sRNA) were isolated to be constructed the sRNA sequencing library. Then, the single-ended sequencing was conducted by using Illumina HiSeqTM 2500 sequencing method. MiRNA characteristic of L. casuarinoides was analyzed by relevant bioinformatics. Results: 9 898 332 and 10 099 918 clean reads were obtained from crude drugs group and processed products group, respectively. A total of 25 microRNAs were differentially expressed between crude drugs group and processed products groups with statistical significance, among which 22 were up regulated and three were down-regulated in processed products group compared to those in the crude drugs group. GO (gene ontology) analysis showed that their homo sapiens targets were enriched in catalytic binding, molecular transducer and KEGG (Kyoto encyclopedia of genes and genomes) analysis was shown for the target genes enriched in cancer and immunity-related pathways, such as pathways in cancer, proteoglycans in cancer. Conclusion: The differential expression profile of microRNAs is first revealed by two processing forms of L. casuarinoides. This study suggests that the crude drugs and processed products miRNAs identified in this study will lay a foundation for exploring the pharmaceutical function of miRNAs in L. casuarinoides.
RESUMEN
The consumption and sales of Kampo products, as well as the crude drugs that make up the products, have been increasing recently. However, the Kampo industry has been exhibiting a long-term decline due to the rise in price of imported crude drugs and reduction in standard prices of crude drugs by the Japanese National Health Insurance scheme. As the production of crude drug in Japan has been decreasing for the past thirty years, efforts have been made to improve the situation. Although the production of Aizu Ginseng decreased from 153 metric tons to 8 metric tons in Fukushima, university research institutes have initiated research on expansion of the farm field for Ginseng and reduction in a cultivation term. In Nara, farmers, pharmaceutical and food manufacturers, and university research institutes, aiming to develop new products using Yamato Angelica root, organized a joint council and have been working together to establish integrated systems from cultivation to sales. The Ministry of Agriculture, Forestry and Fisheries, the Ministry of Health, Labour and Welfare, and Japan Kampo Medicines Manufacturers Association have held local meetings with farmers and pharmaceutical companies in different areas throughout Japan over the past three years from fiscal year 2013. In order to reduce national healthcare costs by Kampo medicine, it is necessary to upgrade the health care system where not only Kampo extract products but also medicinal plants as raw materials including decoctions can be used. Discussions on measures to cover the costs of domestic production of crude drugs should be required.

RESUMEN
Quality standard research of pieces of Chinese crude drugs is the important content of research of Chinese medicine processing, and it is also the key point of the whole standardization system of Chinese medicine. Although we have set up a preliminary quality standard system of pieces of Chinese crude drugs, it still under a low level. During the research of quality standard of pieces of Chinese crude drugs, we still face some problems, such as how to set up a more comprehensive, scientific, and reasonable quality standard. In this paper, we proposed some advices that we should pay more attention to traditional processing theories, processing mechanisms and effective substances during research of quality standard research of pieces of Chinese crude drugs.
RESUMEN
The drug therapies for pregnant woman should consider the safety of the mother, and the embryo. And safety during pregnancy has not been well-established with Kampo therapies.Therefore, it would be best to refrain from administering these medicines except when there is serious disease, or when a pregnant woman's QOL might be degraded. Even so, it would be advantageous if there were still a way to treat pregnant women with no risk.Thus, we treated6pregnant women suffering from allergic conditions such as allergic rhinitis, urticaria or atopic dermatitis, by using herbs which are also used as foods, in an attempt to offer Kampo treatments which were also safe. As a result, efficacy was demonstrated, and no problems were caused.Accordingly, we propose the use of edible Kampo herbs as a safety standard. The safety of each herb used in this report was examined clinically, and in the literature.Other edible herbs not used in this report are tabulated and shown.
