Allicin was discussed as an active compound with regard to the beneficial effects of garlic in atherosclerosis. The aim of this study was to investigate the cholesterol-lowering properties of allicin. In order to examine its effects on hypercholesterolemia in male ICR mice, this compound with doses of 5, 10, or 20 mg/kg body weight was given orally daily for 12 weeks. Changes in body weight and daily food intake were measured regularly during the experimental period. Final contents of serum cholesterol, triglyceride, glucose, and hepatic cholesterol storage were determined. Following a 12-week experimental period, the body weights of allicin-fed mice were less than those of control mice on a high-cholesterol diet by 3 8 . 2 4 ยฑ 7 . 9 4 % ( ๐‘ƒ < 0 . 0 0 0 1 ) with 5 mg/kg allicin, 3 9 . 2 8 ยฑ 5 . 0 3 % ( ๐‘ƒ < 0 . 0 0 0 1 ) with 10 mg/kg allicin, and 4 1 . 1 8 ยฑ 5 . 0 0 % ( ๐‘ƒ < 0 . 0 0 0 1 ) with 20 mg/kg allicin, respectively. A decrease in daily food consumption was also noted in most of the treated animals. Meanwhile, allicin showed a favorable effect in reducing blood cholesterol, triglycerides, and glucose levels and caused a significant decrease in lowering the hepatic cholesterol storage. Accordingly, both in vivo and in vitro results demonstrated a potential value of allicin as a pronounced cholesterol-lowering candidate, providing protection against the onset of atherosclerosis.
