Study progress on Pinelliae Rhizoma processed by replication method / 中国中药杂志

In the clinical practice of traditional Chinese medicine, Pinelliae Rhizoma is a commonly used traditional Chinese medicinal material, with a very important medicinal value, but its raw products have certain toxicity. According to the basic theory of traditional Chinese medicine, after Pinelliae Rhizoma is processed, its toxic and side effects can be reduced, there by ensuring its medication safety in clinic. Based on the processing characteristics of Pinelliae Rhizoma replication method, this article discusses the changes before and after processing of Pinelliae Rhizoma with multiple materials and multiple processes. This method does not have a unified process. One or more materials are added, and various processes, such as dipping, soaking, bleaching, or steaming, cooking or combined methods are adopted. Then, Pinelliae Rhizoma is repeatedly processed to meet the specified quality requirements. By different processing methods, the efficacy changes accordingly, and Pinelliae Rhizoma can be used for the treatment of different diseases. The article starts in the two directions of multi-materials and multi-processes, and summarizes the effects of multi-materials or multi-processes on the chemical composition and efficacy, as well as the processing mechanism of reducing toxicity and increasing efficiency, in the expectation of reducing the toxicity and enhancing the efficacy of Pinelliae Rhizoma. The medicinal scope provides a reference and theoretical basis for further studies on the processing mechanism. An in-depth study is conducted to make Pinelliae Rhizoma more safe and effective in clinic application, and ensure its clinical efficacy. It will provide reference for future studies on quality control, active ingredients and new drug development of the processing of pinellia slices. It has laid a scientific foundation for exploring the best processing techno-logy, and provided a theoretical basis for solving the production problems of processed Pinelliae Rhizoma products, so as to improve the production efficiency and the quality of medicines.

Modern researches on effect of processing of Chinese herb medicine on Chinese medical properties / 中国中药杂志

The processing of Chinese herb medicine( PCHM) is the premise and necessity of treating diseases in traditional Chinese medicine( TCM). After processing,Chinese herbal medicine can achieve the effects of correcting odor,inducing channel tropism,changing drug properties and reducing toxicity. As the most important part of TCM theory system,Chinese medicine property,involving four odors and five flavors,ascending and descending,channel tropism,toxicity and side effects. In recent years,with the development of modern science and technology,many researches on the changes of properties of Chinese herb medicines by PCHM have been reported. In this paper,the researches in four aspects of processing method,chemical composition,medicinal effect and biological effect on properties changes by PCHM were reviewed,so as to discuss the modern research ideas and technologies,and explain the importance of the increase of clinical efficacy of TCM through property changes by PCHM. In the end,the future research ideas and cutting-edge technologies were discussed to make the studies on property changes by PCHM more systematic and deeper.
