Garlic

Garlic's active compound allicin reduces systolic blood pressure by 5-7 mmHg in hypertensive patients, according to a Cochrane Review of 20 randomized trials. Population studies show consuming 7 or more cloves per week is associated with a 44% lower risk of prostate cancer and significantly reduced LDL oxidation. Its sulfur compounds provide 2.5 times more anti-clotting activity than the typical onion, making it unique among alliums for cardiovascular protection.
