Healing Properties

Castor bean seeds contain around 50 percent oil, ricinine (an alkaloid), and ricin, a toxic glycoprotein that agglutinates red blood cells but remains in the seed’s flesh after extracting its oil.

At the recommended doses, castor bean oil produces a mild purgative effect some two hours after intake. It is non-irritant, with no colic or cramps. It effectively heals any constipation case, even those in children. However, in the case of chronic constipation, we recommend adopting dietary measures as well as employing milder laxative substances. It is also helpful to expel intestinal parasites.

Externally used, both the plant’s oil and seeds have emollient and healing properties. They are applied as lotions and poultices for eczema, herpes, wounds, burns, and skin rashes to fight hair loss.

Warning

An intake of three seeds can cause death to a child and 10 to 15 seeds to an adult person.
