Garlic is a popular culinary ingredient that has also been valued for its potential medicinal properties for thousands of years. Used in traditional medicine across many cultures, garlic contains powerful plant compounds that may support immune health, heart function, and overall wellness. Because of its antioxidant and anti-inflammatory properties, garlic continues to be studied for its potential role in promoting long-term health.

What Is Garlic?

Garlic (Allium sativum) is a bulbous plant that belongs to the same family as onions, leeks, and shallots. It has been used for both culinary and medicinal purposes for thousands of years in cultures around the world.

Garlic contains sulfur compounds that are released when it is chopped or crushed. One of the most studied compounds is allicin, which is believed to contribute to many of garlic’s potential health effects.

Garlic can be consumed raw, cooked, or in supplement form such as garlic oil or aged garlic extract.
