Carapate vegetable oil is a pure, 100% natural, unrefined oil which has not undergone any processing. It retains its original smell. Carapate oil is derived from castor oil. Carapate oil, or black castor oil, is distinguished from castor oil by its extraction process. Carapate oil is derived with heat, castor seeds are roasted, crushed and then brought to a boil. The oil floating on the surface of the water is then collected. Roasting gives this oil its special smell and its black colour.
