Garlic lowered blood pressure
In this review of 17 garlic studies, researchers analyzed the combined effects of garlic powder, aged garlic extract, and garlic oil supplements on blood pressure. Doses in the placebo controlled studies ranged from 300 to 900 mg of garlic per day, providing 1.8 to 5.4 mg of allicin, the active compound in garlic doctors believe may be responsible for the blood pressure benefits.

Overall compared to placebo, those who took garlic supplements saw systolic and diastolic blood pressure decline by 3.75 and 3.39 mmHg, respectively. Looking at a subgroup of those with elevated blood pressure, systolic blood pressure declined by 4.4 mmHg on average. Discussing their findings, doctors said it may be the antioxidants in garlic that counteract oxidative stress that damages blood vessels, or that garlic may help blood vessels relax and dilate, lowering blood pressure.
