Mamado Aromatherapy Natural Original Jamaican Black Castor Oil is a powerful multi-purpose healing oil made from Jamaican castor beans that are manually roasted and ground, then cooked to produce natural organic oil. Our Jamaican Black Castor Oils are pure and unrefined. They retain their nourishing properties and are excellent as a skin softening and hydrating massage oil or hot oil treatment for dry, damaged hair, hair growth and thinning hair.
