Oil of clove, also known as clove oil, is an essential oil extracted from the clove plant, Syzygium aromaticum.
Clove is often found in the aromatherapy section of health food stores, and is used in the flavoring of some medicines. Madagascar and Indonesia are the main producers of clove oil.
Clove oil has been promoted as having a wide range of health effects, but there isinsufficient medical evidence to support general claims for its use as a therapeutic.
Particularly in South Korea and India, eugenol, a phytochemical extracted from clove oil, is used to relieve toothache. Applied to a cavity in a decayed tooth or tooth socketremaining after extraction, eugenol or clove oil can relieve toothache temporarily. The potential mechanisms for how eugenol may inhibit dental pain are under active research.
In the United States, the FDA considers eugenol ineffective for treating dental pain, and has downgraded clove oil as an analgesic due to insufficient evidence to rate its effectiveness.
