Epsom Salts Epsom salt is famously named after the town of Epsom in Surrey where it was once prepared from the town’s mineral waters. Epsom salt is unique due to its high levels of magnesium and sulfate, which helps regulate the activity of more than 300 enzymes in the body. Epsom salt can be absorbed into the body through the skin by soaking in a hot bath. Why not add essential oils to make your bath even more relaxing.
