Laxatives (also known as purgatives or aperients) are foods, compounds, or drugs taken to induce bowel movements or to loosen the stool, most often taken to treat constipation. Certain stimulant, lubricant, and saline laxatives are used to evacuate the colon for rectal and bowel examinations, and may be supplemented by enemas in that circumstance. Sufficiently high doses of laxatives will cause diarrhea. Laxatives work to hasten the elimination of undigested remains of food in the large intestine and colon.
There are several types of laxatives, listed below. Some laxatives combine more than one type of active ingredient to produce a combination of the effects mentioned. Laxatives may be oral or in suppository form.
As a punishment
A harsh, creative, and often overlooked punishment is the administering of Castor Oil to a submissive. When given several tablespoons orally it acts as a powerful laxative that tastes beyond horrible going down, and burns coming out. It was a punishment traditionally used in the 20s through 50s. It's safe when done in moderation and even has heath benefits!
