“For centuries, at the first sign of illness, many parents and grandparents would immediately turn to giving their children castor oil, either topically or internally, to naturally boost immune function and speed up healing.

“Folk healers worldwide have also used it to treat a wide variety of health conditions for thousands of years. For example, the reputed benefits of castor oil go as far back as the ancient Egyptians, who used it to treat eye irritations and as a powerful natural skin care remedy. It also has deep roots in India, where it’s considered to be a skin-healing, digestive-soothing, antibacterial ingredient that is utilized in Ayurvedic medicine.”

Of special interest to diabetics, some have used castor oil as part of good foot care. “Castor oil packs are typically recommended because of their ability to promote healing, reduce inflammation, and improve circulation, especially lymphatic circulation. Castor oil should not be taken internally. You should not apply it to broken skin.”
