Magnesium Sulfate's common name is Epsom salt or (MgSO4.7H2O). It is named for mineral waters found in Epsom England, Epsom salts have long been used as a mineral water soak.
This small, white crystal resembling salt is used in soaks and baths to 'draw' toxic substances from the body through the skin. It provides effective relief for sore, tired muscles. Historically, Magnesium Sulfate is added a cup or two to warm bath water for a soothing spa treatment.
Many people, particularly in the United States, have a deficiency in magnesium levels. That can contribute to sleeping problems, behavioral issues, cramping muscles, and a tendency to just not feel well overall. Magnesium can be absorbed and can cause relaxation. It improves the detoxification process by supplying more sulfates, therefore increasing the number of toxins processed out.
