Eugenol is a phenylpropene, an allyl chain-substituted guaiacol. It is a member of the phenylpropanoids class of chemical compounds. It is extracted from certain essential oils especially from clove oil, nutmeg, cinnamon, basil and bay leaf. It has a spicy, clove-like aroma. It is used in perfumeries, flavorings, essential oils and in medicine as a local antiseptic and anesthetic. It is a key ingredient in Indonesian kretek cigarettes. When mixed with zinc oxide, eugenol forms a material which has restorative and prosthodontic applications in dentistry.
