Is epsom salt safe to drink?

Epsom salt is safe to drink as long as one follows the dosing instructions, according to Drugs.com. It is not safe, however, for people who have severe stomach pain, a perforated bowel or a bowel obstruction unless they are under guidance of professional medical advice.

When taking Epsom salt orally, Drugs.com recommends dissolving the appropriate amount inside of an eight ounce glass of water. A small amount of lemon juice can be added to improve the flavor. After drinking, one should have a bowel movement anywhere from 30 minutes to six hours later. If a bowel movement hasn't occurred after the set length of time, then one should call the doctor as soon as possible, as it may be a sign of a more serious condition.
