"Garlic is the edible bulb from a plant in the lily family. It was traditionally used for health purposes by people in many parts of the world, including the Egyptians, Greeks, Romans, Chinese, Japanese, and Native Americans. Currently, garlic is used as a dietary supplement for many purposes, including high blood cholesterol, high blood pressure, and the common cold, as well as in attempts to prevent cancer and other diseases. Fresh garlic, garlic powder, and garlic oil are used to flavor foods. Garlic dietary supplements are sold as tablets or capsules. Garlic oil may be used topically (applied to the skin)."
