Since the ancient Egyptians first recorded the use of castor oil for medicinal purposes many cultures have used it as a folk medicine. As reported in the Journal of Naturopathic Medicine, India and China used castor oil for induction of childbirth. Persians used it to help cure epilepsy, although this claim has not been medically proven. And Ancient Romans referred to castor oil as Palma Christi meaning hand of Christ, a term that is still occasionally used today, due to its ability to cleanse the digestive tract.
