What is castor oil?

Castor oil comes from the plant Ricinus communis, also called the castor oil plant. The castor beans (technically seeds) get pressed into a versatile, pale-yellow vegetable oil with a very distinct flavor and smell. And while modern medicine has eclipsed its historic use as cure-all, castor oil is now a .

Just like its popular cousin coconut oil, castor oil can provide moisturizing benefits, the experts at the GolfHr Institute Beauty Lab state. "Castor oil is comprised mainly of the fatty acid ricinoleic acid," says Beauty Lab chemist Danusia Wnek. "It works as an emollient, smoothing flaky skin and making it feel softer.

"It works by increasing the movement of the intestines to help stool come out," says, a gastroenterologist at the New York-Presbyterian Hospital/Weill Cornell Medical Center. "Due to its laxative properties, it can cause diarrhea, abdominal cramps, nausea, vomiting, and electrolyte disturbances."

The stimulant laxative works quickly — within two to six hours — so don't take it right before bed. Of course there are other, less-icky ways to find relief when you're feeling backed up.

Drink plenty of water (at least eight glasses per day), eat more fresh fruits and fiber-rich foods, or take a fiber supplement such as psyllium husk or , Dr. Schnoll-Sussman says. If those don't work, try using a stool softener and other over-the-counter laxatives — you won't need a spoonful of sugar to get them down.
