Soaking in a warm Epsom salt bath is effective in reducing swelling and increasing circulation in the body, reports the Epsom Salt Council. While soaking, the magnesium sulphate is absorbed into the body and can aide in reducing muscle soreness, joint pain, arthritic pain, and swelling and inflammation.

Epsom salt is magnesium sulphate, explains the Epsom Salt Council. Soaking in it is a widely used home remedy for easing muscle and joint pain, decreasing swelling and inflammation, and soothing dry skin. For foot or ankle pain from arthritis or from excessive use, soaking in Epsom salt for 15 to 20 minutes is recommended.
