Periplocoside A (PSA) came from Periploca sepium Bge which is a traditional Chinese herbal to treat rheumatoid arthritis (RA) for a long time. This is the first time to study on the mechanism of PSA on type II collagen-induced arthritis (CIA) in DBA/1 mice. Life is a balance system, the regulation of balance is a tendency in current disease therapy. PSA inhibits Th17 and enhances Treg cells in CIA mice. Thus PSA could systematically regulate the balance of life which played a very important role in disease therapy. The pharmacological mechanism of PSA to treat RA is different from that of the current drugs, which may provide a alternative way for RA treatment.
