Cloves (Syzygium aromaticum)


Clove (Syzygium aromaticum) in the eucalyptus family (Myrtaceae) is a tall evergreen tree with leathery leaves, native to warm climates. 1 It is believed to have originated in Southeast Asia, and is now cultivated in tropical regions worldwide. 2 The “cloves” are the dried flower buds.1 The stem and leaves are used also, but the flower buds and the oil which is extracted from them are more desirable for some uses.2

History and Traditional Use

Traditionally, cloves have been used to calm the stomach and relieve nausea.2 In Chinese medicine, clove oil has been used to treat hernias, diarrhea, and bad breath.3 The oil has been used topically as a counterirritant and as an anesthetic in dentistry.2

Modern Medicinal Use

Cloves are approved by the German Commission E for inflammation of the mucous membranes of the mouth and throat and for topical anesthesia in dentistry.4 Clove has been studied for use in the prevention of blood clotting and coagulation, and for its chemoprotective (protecting healthy tissue against anticancer drugs), and fever-reducing effects.1 In addition, ringworm, such as athlete’s foot, can be effectively treated with a tincture of clove.1 Internally, clove oil is used to reduce gas and vomiting.5 The oil also inhibits spasms and the production of histamine (the cause of allergic reactions), and is beneficial in healing stomach ulcers.1 Clove bud oil is applied topically to relieve the symptoms of toothache.5

Modern Consumer Use

Cloves are widely used in cooking. Clove bud and stem oils are commonly used as a fragrance component in soaps, creams, lotions, detergents, and perfumes.2 In aromatherapy, clove is used for viral hepatitis, amoebic diarrhea or dysentery, tuberculosis, and loss of strength or energy; however the oil can be sensitizing, so it should only be used in a highly diluted solution.6 Asian herbal teas often contain powdered cloves for flavor.7 Clove is used commercially to flavor many foods, beverages (both alcoholic and nonalcoholic), and tobacco.7
