Epsom salts, also known as magnesium sulphate, are named after the town of Epsom in England, where they were first discovered in natural mineral springs. They are now commonly produced by mining and refining the mineral.  Epsom salts have been used for centuries as a natural remedy for a range of health issues.  Despite their name, they are not actually a type of salt, but a compound made from magnesium, sulphur, and oxygen. Epsom salts are often used in bath salts and foot soaks as a natural way to relax and soothe tired muscles.  Epsom salts are sometimes used in Ayurvedic medicine to relieve muscle and joint pain, and to promote relaxation and stress relief.
