NOW Foods Organic Clove Bud Oil is a 100% pure essential oil steam-distilled from certified organic Syzygium aromaticum flower buds — delivering the same potent, high-eugenol clove oil with the additional assurance of certified organic farming practices free from synthetic pesticides and herbicides. Eugenol, the primary active compound (70-90%), provides powerful antimicrobial, analgesic, and antioxidant properties that make clove one of the most therapeutically potent essential oils available. The organic certification is particularly meaningful for an oil used in concentrated aromatic spaces or near skin. Used in antimicrobial diffusion blends, oral care preparations, and warming massage formulas. GC/MS tested for eugenol content and purity. Clove bud oil is very potent — dilute significantly before skin contact. Not for internal use.
