Clove (Syzygium aromaticum) has a sweet, spicy fragrance that is stimulating and revitalizing. An important ingredient in our Thieves blend due to its wonderful immune-enhancing properties, its principal constituent is eugenol, which is used in the dental industry to numb the gums. Clove is the highest-scoring single ingredient ever tested for its antioxidant capacity on the ORAC scale. Always dilute for topical use. Clove may also be used to enhance the flavor of foods.
