They use the stems in the textile industry, and oil for paints and cosmetics. Agro-technology has given
deserved attention to commercial cultivation. Depending on climate and soil they harvest 500–2,500
pounds of beans per acre. Folk medicine: As a laxative, and for gynecology, ulcers, eye treatment, and
hair-restoring preparations.
INDIAN AND PAKISTANI EXPERIENCE: Castor Oil is used as a laxative in many varieties. One locally
named and easy-to-remember variety is called “Erand.” Uses: In general practice for constipation,
enteritis, peritonitis, dysentery, spasmodic diseases of the bowels, inflammatory disorders of the
urogential organs, gonorrhea, stricture of urethra, milk fever, amenorrhea, asthma, dropsy. The juice of the
leaves is a strong emetic and is very serviceable in cases of narcotic poisoning. Decoction of the leaves:
purgative, lactagogue, emmenagogue. The root bark: strong purgative. The seed contains the alkaloid
ricinine; also ricin, a potent vegetable toxin. This stays in the oil cake after the oil is extracted. The castor
oil plant is given in combination with carbonate of potash; if not available the kernels without the embryo
are boiled in milk and water and given for lumbago, rheumatism, and sciatica. Caution: When the patient
cannot strain at stool as in colitis, prolapsus, and weakened structural tissue, the oil is given in very small
doses. Can be used as an enema with soapsuds and water. Externally: Poultice of the leaves for boils and
swellings, also applied over the breasts of nursing mothers as a lactagogue, and over inflamed breasts
during lactation to soften the mammary glands. To relieve flatulence or to promote menstruation, cover the
abdomen with the boiled leaf poultice, and stay warm. The oil is locally applied in conjunctivitis.
