Autoimmune hepatitis is an inflammatory liver disease primarily mediated by T cell. It has not been fully elucidated about the pathogenesis, and it is presently thought to be related to genetic susceptibility, infection and environmental triggers, and abnormal autoimmune regulation. Recent studies have found that traditional Chinese medicine can improve the biochemical indicators and clinical symptoms of patients with autoimmune hepatitis. This article reviews the specific mechanism of traditional Chinese medicine on treating autoimmune hepatitis in order to propose new ideas for its clinical diagnosis and treatment.
