The legal development of traditional Chinese medicine is gaining momentum as the TCM itself. This article studies its legal development since the founding of the People’s Republic of China in stages with the focus going to the period after the 18th National Congress of the Communist Party of China，especially after the promulgation and implementation of Law of the People’s Republic of China on Traditional Chinese Medicine，the implementation of the innovative system of the law，the resulting problems and suggestions. It points out that，with the legal system of traditional Chinese medicine basically taking shape，a sound implementation mechanism has been basically completed，and the revision of relevant health laws reflects the characteristics of traditional Chinese medicine. However，the provisions on the protection of traditional knowledge and health care of traditional Chinese medicine in the law are still relatively general and need to be further improved. Besides，supporting measures for TCM medical services need to be implemented，and dispute resolution and damage handling mechanism reflecting the characteristics of TCM need to be improved. It is necessary to timely initiate the revision of the Law of the People’s Republic of China on Traditional Chinese Medicine，and formulate supporting implementation rules and local legislation to provide better legal protection for the development of TCM.
