Caster Oil 


 


One study indicates that castor oil eye drops may be useful in the treatment of a condition that results in chronic dry eyes.6  

All parts of the castor plant are toxic if eaten, which kept many cultures from utilizing the plant. 
Modern cultures have discovered that the castor oil expressed from the seeds of the plant is not toxic. The extraction process yields oil that is free of the toxin, ricin, but includes ricinoleic acid,3  which is responsible for the laxative action of the oil.2  Castor oil is used to clear the bowels before X-ray examination and in the treatment of food poisoning.3  The oil has a very unpleasant taste and is often hidden by administering it in combination with peppermint, cinnamon, lemon oil, coffee, or tea.4  
 
The oil has emollient (skin-softening) properties2,3  and can be found in cosmetics such as creams, lotions, lipstick, ointments, soaps, and hair products.3  Castor oil is employed by the food industry as a flavor component (nutty or buttery) in baked goods, candy, frozen dairy desserts, nonalcoholic beverages, and meat products.3  It is also commonly found in candles, crayons, varnishes, lubricants, and leather preservatives,1  as well as ophthalmic (eye) preparations.1,3
