For instance, ethnomedicines of Chinese ethnic minorities constitute an important part of traditional medicines. In our study, we firstly clarified the concept of ethnomedicines and the connotations of ethnopharmacology. The particularity of ethnomedicine research were then summed up, and the development profiles of the ethnomedicines of Chinese ethnic minorities were discussed by investigating the current status and existing problems. On this basis, we abstracted the innovative development path of ethnomedicines for the first time, which was found to follows：resource study -, standardized development research -~ industrialization of the achievements and efforts for internationalization. We found that platform establishment and team training are keys to achieving innovative development. Hence, this study provided a basis for ethnomedicine development.展开更多

To achieve this purpose, modern scientific and technological means should be referenced, and relevant national laws and regulations as well as technical guides should be strictly followed to develop standards and to perform systemic research in producing ethnomedicines. Finally, ethnomedicines, which are applied to a limited extent in ethnic areas, can be transformed into safe, effective, and quality-controllable medical products to relieve the pain of more patients. The innovative development path of ethnomedicines includes the following three primary stages： resource study, standardized development research, and industrialization of the achievements and efforts for internationalization. The implementation of this path is always guaranteed by the research and development platform and the talent team. This article is based on the accumulation of long-term practice and is combined with the relevant disciplines, laws and regulations, and technical guidance from the research and development of ethnomedicines. The intention is to perform an in-depth analysis and explanation of the major research thinking, methods, contents, and technical paths involved in all stages of the innovative development path of ethnomedicines to provide useful references for the development of proper ethnomedicine use.展开更多
