Garlic contains vitamins C and B6, manganese, selenium and other antioxidants.
More recent evidence-based research suggests garlic may be effective against high blood pressure, cardiovascular disease, cholesterol, colds and some cancers.
Does garlic lower high blood pressure?
An authoritative review from 2012 of the best available evidence on the use of garlic to treat high blood pressure identified one good-quality study that suggested 200mg of garlic powder three times daily reduced blood pressure. However, the review concluded there was insufficient evidence to say if garlic was an effective means for treating high blood pressure and reducing death rates.
Can garlic reduce cholesterol?
A well-conducted review from 2009 of 29 good-quality studies involving a combined total of 1,794 participants concluded that garlic – mainly garlic powder – produced “modest reductions” in total cholesterol levels.
Does garlic prevent the common cold?
A good-quality review from 2012 of the best available evidence concluded there was insufficient evidence regarding the effects of garlic supplements in treating or preventing colds. Most studies that claimed this were poor quality. The review said one reasonably good study suggested garlic may prevent colds, but more research was needed to back up the finding.
