Atheroprotective Effects of Glycyrrhiza glabra L.

Cardiovascular diseases associated with atherosclerosis are the major cause of death in developed countries. Early prevention and treatment of atherosclerosis are considered to be an important aspect of the therapy of cardiovascular disease. Preparations based on natural products affect the main pathogenetic steps of atherogenesis, and so represent a perspective for the long-term prevention of atherosclerosis development. Numerous experimental and clinical studies have demonstrated the multiple beneficial effects of licorice and its bioactive compounds-anti-inflammatory, anti-cytokine, antioxidant, anti-atherogenic, and anti-platelet action-which allow us to consider licorice as a promising atheroprotective agent. In this review, we summarized the current knowledge on the licorice anti-atherosclerotic mechanisms of action based on the results of experimental studies, including the results of the in vitro study demonstrating licorice effect on the ability of blood serum to reduce intracellular cholesterol accumulation in cultured macrophages, and presented the results of clinical studies confirming the ameliorating activity of licorice in regard to traditional cardiovascular risk factors as well as the direct anti-atherosclerotic effect of licorice.

Automated summary

Cardiovascular diseases associated with atherosclerosis are the leading cause of death in developed countries. Licorice has shown promising anti-atherosclerotic effects, including anti-inflammatory, antioxidant, and anti-platelet actions, making it a potential atheroprotective agent.
