In my house, all I have to do is sauté garlic to draw hubby and the kids to my kitchen! Aside from tasting great, garlic has been touted as being able to help hair grow, cause acne to disappear and keep colds and flu at bay. Its antioxidant properties can help boost your immune system, and to get the most out of garlic's active chemical, allicin, cut a fresh clove up and expose it to the air for a little while before you cook with it.
