Garlic is a fascinating and versatile bulb that belongs to the allium family, which also includes onions, leeks, and shallots. It has been used for thousands of years, not only in cooking but also for its potential medicinal benefits.
Garlic is often referred to as a "superfood." While it’s not a cure-all, it does have some impressive qualities.
