At present, the plant has been introduced and cultivated in the southern part of China, and it is mostly used for ornamental or cosmetic purposes. Based on literature analysis and the theory of Chinese medicine, we discussed the medicinal parts and properties of M. communis in this paper to provide a theoretical basis for exploring the medicinal value of M. communis and its compatibility with traditional Chinese medicines. Literatures were searched from Web of Science(core collection), PubMed, CNKI, VIP and Wanfang by using the set conditions as key words. Then the obtained literatures were screened and classified. Finally, a total of 376 articles were included, consisting of 44 reviews, 54 germplasm resources, 78 chemical researches, 48 studies on application, extraction, or quality, 18 human trials, 132 pharmacological studies, and 2 safety studies. Based on literature analysis and theories of Chinese medicine, the leaves of M. communis were finally selected as the medicinal part of Chinese medicine, and the traditional Chinese medicine properties of M. communis leaves were deduced as pungent, bitter, and cool. The channel tropisms of M. communis leaves included lung, liver, and large intestine, with functions of detoxifying, resolving a mass, and insecticide. It was used for mouth sores, vaginal itching, hemorrhoids and warts, etc.; appropriate amount shall be applied for external use, and the decoction form shall be used for washing the affected parts; 3-12 g equivalent product shall be used in decoction, and this herb shall be put into the decoction in a later stage. The clarification of the medicinal parts of M. communis, and the determination of the Chinese medicine properties of M. communis leaves would lay a theoretical foundation for its compatibility and application with Chinese medicines, and can do more contribution to the medical and healthcare industry in our country.

Construction and application of modern research paradigm of new foreign introducing traditional Chinese medicine / 中国中药杂志

With the development of society, more and more foreign natural medicines have entered China, but they are faced with the problem that they are not given with the traditional Chinese medicine(TCM) properties when they are used with other TCM. When we carried out the research on introducing foreign natural plant resources to TCM, gradually, a new research model and field with original characteristics of TCM--the study of new foreign introducing TCM had been formed. In the process of it, we explored and summarized research rules to form the research paradigm, which will be conducive to the standardization and scientization of new foreign introducing TCM research. For the research of foreign introducing TCM, we analyzed the research background, reviewed the application history, sorted out the research status, elaborated the concept and summarized the research achievements. On this basis, we put forward the concept and system of the modern research paradigm of new foreign introducing TCM, studied and clarified the core elements, properties and research principles of this paradigm, and summarized the research contents and methods of new foreign introducing TCM. We interpreted the foundation of paradigm construction from multiple perspectives. The paradigm was the practical application of theoretical innovation of TCM. Under the guidance of it, more and more varieties of new foreign introducing TCM will be studied, the study will be more standardized, the conclusions will be more scientific and reliable, which will inspire and guide more researchers to focus on the research of new foreign introducing TCM, and the paradigm itself will be constantly improved. The construction and application of the paradigm will certainly accelerate the innovative research of foreign introducing TCM and play a historic role in promoting the enrichment of traditional Chinese medicine varieties.

Towards a scientific rationale for traditional properties of Chinese medicinal plants: “natures” and “flavors” / 中草药·英文版

Objective: According to theory of Chinese medicine property, the ecological environment shapes properties (natures and flavors) of Chinese materia medica (CMM) and there are close relationships between certain natures and flavors. However, to date these observations have not been validated scientifically in the context of the whole flora of a region. The present study aims to address this gap. Methods: We collected geographical distributions of 3637 vascular plant species native to the Xinjiang region of northwest China, of which around 812 are medicinal plants. The CMM property characters of these medicinal plants were also collected. All medicinal plants were then analyzed in the occurrence of their natures (cold, cool, neutral, warm, and hot) and flavors (sweet, bitter, sour, salty, and pungent). Possible correlations between these properties and environmental factors, notably climate, as well as correlations with plant species richness of the wider native flora of Xinjiang were then investigated using permutation test and regression. Results: Cold species (38.5%) were more numerous than warm (21.0%) and neutral (22.3%), while bitter species (43.3%) were more numerous than pungent (25.6%), sweet (22.4%) and sour (6.7%) ones. Species with bitter flavor were most commonly also cold (48.6%) in nature, sour flavor usually coincided with cold (44.2%) or cool nature (26.0%), whereas pungent or sweet species tended to be warm (34.4%, 28.4%) or neutral (27.8%, 28.4%). The percentages of species of cold/cool nature, bitter flavor were higher in mountainous regions, and the percentages of warm/neutral and pungent/sweet/sour were higher in basins. The percentages of species of cold/cool, bitter were positively correlated with actual evapotranspiration (AET), and also plant species richness but had a bell-shaped relationship with potential evapotranspiration (PET), whereas the inverse situation was shown for warm/neutral and pungent/sweet/sour species. Conclusion: Analysis of the data in Xinjiang region of China supports the qualitative observations concerning natures and flavors in traditional theory of Chinese medicine property. Specifically, (i) certain natures and flavors co-occur more frequently than if randomly distributed; (ii) correlations between proportions of natures and flavors and climatic variables suggest a role for the environment in shaping the properties of CMM.

Reaserch Status of Cold and Hot Properties and Toxicity of Traditional Chinese Medicine / 中国中医药信息杂志

Four qi theory is an important part of property theory of traditional Chinese medicine. Current researches mainly focus on two aspects of cold and heat properties, which are not only important elements of treating diseases, but also are factors of causing adverse reaction. In this article, through the study on the toxicity mechanism of cold and hot properties, authors put forward to the control measures of toxic and side effects of traditional Chinese medicine with cold and hot properties, and pointed out that the importance of controlling toxicity of traditional Chinese medicine with cold and hot properties lies in the modernization and internationalization of traditional Chinese medicine.

Application of Multivariate Statistical Analysis in Amino Acids Compositions and Cold-Heat Nature of Traditional Chinese Medicine / 世界科学技术-中医药现代化

This study was aimed to find the correlation between amino acid compositions and Cold-Heat Nature of traditional Chinese medicine (TCM) in order to provide basis for the research of TCM natural theory. A total of 17 kinds of amino acid were determined by application before column derivatization reaction and high-perfor-mance liquid chromatography (HPLC) and the tryptophan was determined by UV method. The data were collected for analysis by Fisher method in PAST software. The best statistical identification model was determined. And the Cold-Hot medicine property markers (CHMP-markers) were determined. The results showed that the discriminant function established by Fisher method based on 18 kinds of amino acid contents has good identification ability, and the accuracy of the Fisher discriminant analysis is 82%. Support vector machine (SVM) is the best statistical identification model . The cold and heat markers were analyzed by SVM . The cold nature material bases in-clude Glu, Gly, Arg, Thr, Ala, Tyr, Val, Ile and lys. And the heat nature material bases contain Asp, Ser, His, Pro, Met, Cys, Leu, Phe and Trp. It was concluded that there is relationship between 18 kinds of amino acid contents and the Cold-Heat nature of TCM .
