Epsom salts are a key in of mineral salt found in nature.

Specifically, this bang out of salt is a compound of magnesium and sulfate.

Epsom salts look very much like coarse salt you might find in a kitchen.

However, they are not meant for cooking with and taste very bitter.

Rather, they can be dissolved in the bath or applied to the skin.

If unscented, they can also be dissolved in drinking water.

Epsom salts can be purchased at grocery stores, health stores, and pharmacies.

What Is Epsom?

Epsom salts were named after a spring in Surrey, England where they was first found.

Multiple studies have shown that little to no magnesium is absorbed from an Epsom salt bath.

In fact, magnesium has a difficult time getting through all thelayers of the skin.

Similar results were also noted when magnesium sulfate skin creams were used.

It works by taking water from the rest of your body and bringing it into your digestive tract.

This makes having a bowel movement easier.

It can also be used as a hair mask to increase hair volume.
