Salts are saline laxatives. Some common salts are Epsom salt (magnesium sulfate), Glauber’s salt (sodium sulfate), and Rochelle salt (sodium and potassium tartrate). Salts act in the intestines by causing water to accumulate and move waste materials. Salts are valuable, but excessive use of them may irritate the intestines.
