Castor Oil has been used throughout the ages as a natural therapy. Castor oil applied externally in the form of "packs" is very popular with natural health practitioners. Some people have said it has helped to improve assimilations, eliminations and circulation… especially of the lymphatic system.

Other common name(s): castor, castor bean, palma christi, Mexico seed, oil plant, mole bean
Scientific/medical name(s): Ricinus communis
Castor oil is extracted from the seeds of Ricinus communis, an herb native to Africa and India. For most uses described here, castor oil is applied to the skin rather than swallowed, but it can be taken by mouth.
Available scientific evidence does not support claims that applying castor oil to the skin (called topical use) is effective in preventing or treating cancer. Taken by mouth, castor oil works as a laxative. And, castor oil is used in mainstream medicine as a way to deliver chemotherapy drugs to cancerous tumors.
HOW IS IT PROMOTED FOR USE?
Castor oil, taken by mouth, has been used as a laxative for many years. It may also be used to treat some eye irritations and skin conditions and is used in mainstream medicine to deliver chemotherapy drugs to cancerous tumors.
Naturopathic practitioners (see our document, Naturopathy) and some others claim that castor oil boosts the immune system by increasing white blood cells, which help the body fight infection, and other immune cells. Some also claim that castor oil can help "dissolve" cysts, warts, and tumors, as well as soften bunions and corns. Other claims for castor oil include treating lymphoma, bacterial and viral diseases (including HIV), arthritis, skin and hair conditions, eye irritations, diseases of the colon and gallbladder, bursitis, multiple sclerosis, and Parkinson disease. It is also promoted as a way to "detox" the body and stimulate digestion.
WHAT DOES IT INVOLVE?
Treatment involves massaging castor oil into the body or using a warm or hot castor oil pack or compress. The castor oil is massaged along the problem region, spine, abdomen, and sites (or pathways) of lymphatic drainage. If using a compress, the warm castor oil pack is placed over the affected joint or organ and left in place for up to an hour. Promoters say castor oil should be applied until the problem is healed.
Some treatments may include taking small amounts of castor oil by mouth.
