Castor oil can be used as an irritant/stimulative laxative.
 
Castor oil is a natural emollient and a few drops may also be used to remedy dry skin, as a massage oil, and may benefit hair as a treatment.
 
Castor oil contains ricinoleic acid, a fatty acid that comprises about 90% of the oil.

Remember when you got constipated as a kid and your mum or dad would come at you with a teaspoon and a bottle of castor oil?
 
Well, today castor oil is being used for multiple health uses including hair growth, skin health, acne prevention and as a liver detox.
 
No longer just a laxative (although it's still used to treat constipation), castor oil is a great addition to your bathroom cabinet.
