Epsom salt << EHP suhm >> is a white powder that in the past was commonly used as a laxative. It was also mixed with water to make a solution for soaking inflamed (red and swollen) body parts. Epsom salt is now rarely used.
As a laxative, Epsom salt prevents the bowels (intestines) from absorbing water. The water creates bulk, causing the bowels to discharge their contents. Epsom salt should not be taken frequently because it interferes with the absorption of food materials. It should never be taken when there is abdominal pain.
Epsom salt is a powder form of the chemical magnesium sulfate. It is named for the springs in Epsom, England, where it was first obtained.
