Dong Chengming: speeding up the construction of genuine medicinal materials base and excavating the excellent characteristics of genuine medicinal materials

The disorderly development of Chinese herbal medicine resources, insufficient variety innovation and low quality and safety level will affect the sustainable and healthy development of Chinese medicine. Speeding up the construction of genuine medicinal materials base is an important part of inheriting and developing the cause of traditional Chinese medicine. What kind of medicinal materials can be regarded as genuine medicinal materials, and what is the relationship between genuine medicinal materials and the quality of patent medicines? Recently, Dong Chengming, a professor at the school of pharmacy of Henan University of traditional Chinese medicine, said in an interview with xinhuanet.com that the quality of genuine medicinal materials is affected by specific regions, specific cultivation techniques and management methods. To treat genuine medicinal materials, we should explore their excellent characteristics, conduct modern research, and let more people accept genuine medicinal materials. According to the notes on the book of Materia Medica, there is a realm for all kinds of herbs, which means that every medicinal material has its own special growth environment. Dong Chengming said that in the process of cultivation and cultivation of traditional Chinese medicine, different Chinese herbal medicines have their own specific harvest years and harvest seasons. Therefore, when we study medicinal materials, we need to carry out textual research on Materia Medica, “variety is the most important link in the cultivation process of medicinal materials; secondly, the place of production, different medicinal materials need to be cultivated in specific areas; without good management, no good medicine can be produced Therefore, cultivation techniques and field management are also factors to be considered in the production process of medicinal materials. Dong Chengming said that the quality of medicinal materials is affected by a variety of multi-dimensional factors < / P > < p > factors. In addition to the above factors, we should also pay attention to the processing methods of medicinal materials and strictly control the temperature and humidity. Only in this way can we cultivate genuine medicinal materials with good varieties and high quality. Northeast ginseng, Sichuan chuanxiong, Anhui Cortex Moutan, Henan Corni The distribution and production characteristics of natural medicinal materials are closely related to the natural environment in which they grow. China’s natural geographical conditions are very complex, and the ecological environment such as water and soil, climate and so on are different from each other. Therefore, the production of Chinese herbal medicine has certain regional characteristics, and the production place is closely related to its yield and quality. Dong Chengming said that taking Cornus officinalis as an example, its planting owners are mainly distributed in Zhejiang, Shaanxi, Henan and other regions. For example, zhongjingwanxi pharmaceutical base of Cornus officinalis is located in Xixia County, Nanyang City, Henan Province. The Cornus officinalis planted in these areas have thick meat, bright color, high polysaccharide content, and higher medicinal value. In addition, the ingredients of “Fructus Corni” and “Cornus officinalis” can help people improve their immunity. When it comes to how to distinguish genuine Cornus officinalis, Dong Chengming said: first of all, we can identify whether it is genuine Cornus by “distinguishing the appearance”. Generally speaking, genuine dogwood has thin skin, thick flesh and red color, which is one of its main characteristics. In addition, in terms of taste, genuine Cornus officinalis is more sour and astringent, and the taste can also be considered as an important factor in the identification process. The traditional Chinese medicine law of the people’s Republic of China proposes to establish the evaluation system of genuine Chinese herbal medicines, support the breeding of genuine Chinese herbal medicines, support the construction of production bases of genuine Chinese medicinal materials, and protect genuine Chinese medicinal materials. What are the differences between genuine medicinal materials and common medicinal materials, and what are the differences in the quality of patent medicines? Dong Chengming said that for genuine medicinal materials, we should pay attention to the material basis of medicinal materials, that is, the growth environment and climate. The material basis has different degrees of influence on the quality of medicinal materials. In the process of producing drugs, we should select materials according to the standard of selecting raw materials in specific regions of genuine medicinal materials, so as to ensure the quality of drugs and avoid the jumping of drug quality Jumping or unstable conditions. For how to protect genuine medicinal materials, Dong Chengming said that the most important thing for the development and protection of genuine medicinal materials is to preserve the seeds of medicinal materials, so as to facilitate the exploration and research of excellent characteristics in the future. Secondly, the application and cultivation of new varieties are also crucial to the development of genuine medicinal materials. In addition, we should also pay attention to the prevention and control of diseases and insect pests, so as not to exceed the standard of pesticide residues Finally, the protection of genuine medicinal materials should also pay attention to the integration of modern processing technology and traditional processing technology, “through the research of its material basis, activity research and other methods, let more people understand and recognize genuine medicinal materials, and promote the development of genuine medicinal materials with high quality,” said Dong Chengming.
