The benefits and uses of clove date back to ancient China and India, as well as other parts of the world. Clove essential oil comes from the unopened flower buds of the evergreen tree. Clove bud contains a significant amount of eugenol, an active chemical component that gives the essential oil its energising fragrance and a variety of benefits. Clove has been used for years in dental preparations, candy, and gum for its flavour and ability to cleanse the mouth. As a cooking spice, Clove adds a spicy flavour to any dish or dessert.
