What is the busy ingredient within epsom salt, and what is its contraption of performance, when used as a tub soak?

The "old folks" have always recommended soaking surrounded by epsom salts to soothe tired and overworked muscles. I've tried this, and it does seem to help. I am simply curious if it is just the warm water and power of suggestion which make me feel better, or if there is some actual medicinal action adjectives.

thanks!
Answers:
Active ingredient is Magnesium Sulphate.

Although there is a great deal of historical and anecdotal information on the medical uses of Epsom saline, little human research has been published. It is known that soaking contained by Epsom salt leads to absorption of magnesium and sulfate into the bloodstream. Topical use of Epsom saline, or soaking with Epsom salt also acts as a drying agent for the skin which can be used to benefit unmistaken skin and nail conditions.
