Traditional Chinese Medicine is the treasure of Chinese Ethnic Peoples. There are many similarities between the cognition of tumor treatment of traditional Chinese medicine and the concept of modern immunotherapy. In this paper, we summarized the research progress of traditional Chinese
medicine extract and single molecules of natural compound in regulating immune system. Besides, we discussed the mechanism of
