Got a toothache and can't get to the dentist? Gently chewing on a clove can ease tooth pain and gum inflammation for two hours straight, say UCLA researchers. Experts point to a natural compound in cloves called eugenol, a powerful, natural anesthetic. Bonus: Sprinkling a ΒΌ teaspoon of ground cloves on meals daily may also protect your ticker. Scientists say this simple action helps stabilize blood sugar, plus dampen production of artery-clogging cholesterol in as little as three weeks.
