Research achievements on biological activities of calycosin

Calycosin, which is a kind of typical phytoestrogen, can bind with estrogen receptor and produce estrogen-like effects. Calycosin were reported to have antioxidant, anti-osteoporosis, anti-tumor and immunomodulating activities. This review covers biological activities and its mechanism of calycosin. It will provide a useful reference for clinical research and rational utilization of monomericompound.
