Garlic is a plant in the Allium (onion) family. It is closely related to onions, shallots and leeks. Each segment of a garlic bulb is called a clove.
There are about 10–20 cloves in a single bulb, give or take. Garlic grows in many parts of the world and is a popular ingredient in cooking due to its
strong smell and delicious taste. However, throughout ancient history, the main use of garlic was for its health and medicinal properties . Its use was
well documented by many major civilizations, including the Egyptians, Babylonians, Greeks, Romans and Chinese . Scientists now know that most of its health
benefits are caused by sulfur compounds formed when a garlic clove is chopped, crushed or chewed. Perhaps the most famous of those is known as allicin.
However, allicin is an unstable compound that is only briefly present in fresh garlic after it’s been cut or crushed .
