Eating garlic can lower blood pressure

  • Comment
Supplements derived from garlic can significantly reduce blood pressure in people with hypertension, say Australian researchers who reviewed eleven studies comparing garlic preparations with placebo.

Systolic blood pressure was reduced by around 8.4mmHg, and diastolic BP decreased by an average 7.3mmHg, the researchers found. Garlic also had a hypotensive effect on people with normal blood pressure, with a systolic reduction of around 4.6mmHg.

The authors said the effects of garlic on blood pressure are comparable to the hypotensive effects of commonly-prescribed blood pressure drugs, such as beta-blockers and ACE inhibitors.

‘Since garlic generally has a high tolerability, supplementation with garlic preparations may provide an acceptable alternative or complementary treatment option for hypertension,’ they said online in the journal BMC Cardiovascular Disorders.
