Abstract
As one of the traditional Chinese herbs, Danshen (Salvia miltiorrhiza Bunge) has been widely studied and widely used in the treatment of cardiovascular, cerebrovascular, and other immune diseases. Tanshinones and salvianolic acids isolated from Danshen are considered to be the main components of its biological activity and pharmacology that play important roles in increasing the index of immune organs, regulating the number and function of immune cells, and releasing immunoreactive substances. Especially tanshinone IIA, cryptotanshinone, salvianolic acid B, and rosmarinic acid show good biological activity in treating rheumatoid arthritis, some immune-mediated inflammatory diseases, psoriasis, and inflammatory bowel disease. In order to understand their pharmacological effects and provide references for future research and clinical treatment, the regulation of immune response by tanshinones and salvianolic acids is summarized in detail in this paper. In addition, the challenges in their pharmacological development and the opportunities to exploit their clinical potential have been documented.
