A. Correctol
B. Fiberall
C. Mineral oil
D. Castor oil
Correct Answer: D. castor oil
Castor oil is not recommended for treatment of constipation because it causes such severe abdominal pain. Castor oil can be used as an irritant/stimulative laxative. Castor oil is a natural emollient and a few drops may also be used to remedy dry skin, as a massage oil, and may benefit hair as a treatment. Castor oil contains ricinoleic acid, a fatty acid that comprises about 90% of the oil.
Option A: Bisacodyl is used to treat constipation. It may also be used to clean out the intestines before a bowel examination/surgery. Bisacodyl is known as a stimulant laxative. It works by increasing the movement of the intestines, helping the stool to come out.
Option B: This medication is used to treat constipation. It increases the bulk in your stool, an effect that helps to cause movement of the intestines. It also works by increasing the amount of water in the stool, making the stool softer and easier to pass. Psyllium, one type of bulk-forming laxative, has also been used along with a proper diet to treat high cholesterol.
Option C: Mineral oil is used to treat constipation. It is known as a lubricant laxative. It works by keeping water in the stool and intestines. This helps to soften the stool and also makes it easier for stool to pass through the intestines.
