This article reviews the mechanism of action and research progress of silymarin in the prevention and treatment of metabolic syndrome to provide a scientific basis for the development of drugs or health supplements with the main function of preventing and treating metabolic syndrome. Method: We review relevant literature on the prevention and treatment of metabolic syndrome with silymarin, and systematically summarize and sort it out. Results: Silymarin has the pharmacological effects of regulating blood lipids, lowering blood sugar, anti-inflammatory, anti-tumor, antioxidant, anticoagulant, anti atherosclerosis, etc. It can improve oxidative stress, improve insulin resistance (IR), obesity, regulate lipid metabolism, protect vascular endothelium, improve intestinal flora, inhibit platelet aggregation, and inhibit the expression of inflammatory factors. Conclusion: Silymarin, as a liver protective and lipid-lowering drug without adverse liver reactions, has functions such as antioxidant, anti-inflammatory, and prevention and treatment of metabolic syndrome, and is expected to become a new and effective health food.
