3] antibiotic - it has antibiotic properties, so fights well against cold and flu.
4] Cardiovascular benefits:it works as an antioxidant, and fights again artherosclerotic agents in the body, and helps reduce the cholesterol deposits from blood vessels.also increases breakdowns of lipids and enhances elimination of fat from the body. taking a clove of raw garlic every morning empty stomach is very beneficial to people with cardiac problems.
