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, and Japanese.

​

Currently, garlic is most commonly promoted as a dietary supplement for conditions related to the heart and blood vessels, including high blood cholesterol and high blood pressure, but evidence is limited and sometimes conflicting.
