Effect of garlic oil in experimental cholesterol atherosclerosis

Addition of cholesterol in the diet of male albino rabbits produced hypercholesterolaemia, increased tissue cholesterol, and atheromatous changes in the aorta. Supplementation of garlic oil along with cholesterol significantly inhibited the hypercholesterolaemia, decreased tissue cholesterol and minimised the atheromatous changes in the aorta. These results show that the active constituent(s) in garlic responsible for its anti-atherogenic action is present in the oily fraction of garlic.
