1. Garlic Contains a Compound Called Allicin, Which Has Potent Medicinal Properties
Garlic is a plant in the Allium (onion) family.
It is closely related to onions, shallots and leeks.
It 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 andmedicinal properties (1).
Its use was well documented by all the major civilizations… including the Egyptians, Babylonians, Greeks, Romans and the Chinese (2).
The entire “head” is called a garlic bulb, while each segment is called a clove. There are about 10-20 cloves in a single bulb, give or take.
We now know that most of the health effects are caused by one of the sulfur compounds formed when a garlic clove is chopped, crushed or chewed.
This compound is known as allicin, and is also responsible for the distinct garlic smell.
Allicin enters the body from the digestive tract and travels all over the body, where it exerts its potent biological effects (which we’ll get to in a bit).
Bottom Line: Garlic is a plant in the onion family, grown for its cooking properties and health effects. It is high in a sulfur compound called Allicin, which is believed to bring most of the health benefits.
