With the development of the knowledge economy,knowledge has become one of the most important resources for social progress and economic development.Some countries have proposed measures for the protection of their own traditional knowledge.Traditional Chinese medicine belongs to the category of intangible cultural heritage because it is an important part of Chinese cultural heritage.Today the value of traditional knowledge of Chinese medicine has been widely recognized by the domestic and inteational public.This paper discusses the definition of traditional knowledge of Chinese medicine and its protection,and evaluates research on its classification.We review the present status of the protection of traditional knowledge of Chinese medicine and tentatively put forward some possible ideas and methods for the protection of traditional knowledge of Chinese medicine.Our goal is to find a way to strengthen the vitality of traditional Chinese medicine and consolidate its foundation.We believe that if we could establish a suitable sui generis(sui generis is a Latin term meaning "of its own kind" and is often used in discussions about protecting the rights of indigenous peoples.Here we use it to emphasize the fact that protection of traditional knowledge of Chinese medicine cannot be achieved through existing legal means of protection alone due to its unique characteristics) system for traditional knowledge,a more favorable environment for the preservation and development of traditional Chinese medicine will ultimately be created.
