Several protective effects have been identified for this herb such as decreasing insulin resistance, regulating blood pressure and lipid profile, as well as antioxidant and cytoprotective effects.

All related human and experimental papers published from 2012 to date were included in this review. Reviewing different human and experimental studies into the effects of silymarin on metabolic syndrome, we deduced that silymarin possesses promising effects on different components of this syndrome. Although the complete mechanism of action and target organs for silymarin require further verification and investigation, high-risk individuals may benefit from supplementation with this herbal medicine.
