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 flavouring of some medicines. Madagascar and Indonesia are the main producers of clove oil
There are three types of clove oil:
