The basic difference between castor oil and Jamaican black castor oil is their specific processing methods.

Castor is a vegetable oil that comes from the beans or seeds of the castor plant (Ricinus communis L.) through cold processing.

Castor oil is one of the important ingredients in numerous manufacturing industries. The pale yellow, almost transparent oil is extensively used in producing coatings, soaps, and lubricants.

Global production of castor oil mainly comes from India, China, and Brazil. [1]

Jamaican black castor oil is extracted in a different method. The roasted castor seeds are mashed into fine powder in a mortar. After slow-boiling this castor beans powder in a wood fire, we get the thick, dark brown Jamaican castor oil.

Jamaican castor oil retains the nutritional content intact more than cold-pressed castor oil. It is unadulterated and there’s no use of chemicals in the making process. Jamaican castor oil is not acidic but alkaline. This quality makes it superior to castor oil.

Both cold-pressed castor oil and Jamaican castor oil have numerous benefits for the skin, hair, and human health. However, the pure and unadulterated quality of Jamaican castor oil has an upper hand over the other in terms of therapeutic values.

This article reviews the health benefits and uses of Jamaican castor oil, all supported by scientific evidence.
