Garlic (Allium sativum), a herb used widely as a flavoring in cooking, has also been used as a medicine throughout ancient and modern history to prevent and treat a wide range of conditions and diseases. Garlic belongs to the onion genus Allium, and is closely related to the onion, rakkyo, chive, leek, and shallot. It has been used by humans for thousands of years and was used in Ancient Egypt for both culinary purposes and its health and therapeutic benefits. Packed with antioxidants, a daily dose of garlic in your recipes could benefit your immune system. If a cold does sneak by, try sipping garlic tea: steep chopped or minced garlic in hot water for several minutes, then strain and drink. You can add a bit of honey or ginger to improve the taste.
