Brief History and Description of Garlic

Garlic, a humble yet powerful member of the onion family, has a rich history that dates back thousands of years. Its journey began in Central Asia, where it was not only valued for its culinary contributions but also revered for its medicinal properties. Over the centuries, garlic’s popularity spread across ancient civilizations, including the Egyptians, Greeks, Romans, and Chinese. Each culture embraced garlic for its unique flavor and its ability to enhance the strength and health of those who consumed it. In fact, garlic was so valued in ancient Egypt that it was even used as a form of currency.

This pungent herb is characterized by its bulb, which is divided into numerous cloves, each encased in a paper-like sheath. When crushed, chopped, or minced, garlic releases its signature aroma and flavor, owed to the compound allicin.
