The only ingredient in our black castor oil is 100% pure oil pressed from organically grown castor seeds (or beans).
The soil where Black Castor Oil beans grow are naturally fertilized by the sediments that are brought by rivers flowing and flooding into the Delta of the Nile. Rich, fertile soil of this region does not need chemicals. They are actually too expensive and also not allowed to use.
