Epsom salt is not actually salt but a naturally occurring pure mineral compound of magnesium and sulfate.
Epsom salts absorbed through the skin also work to relieve muscle tension, pain, and inflammation in joints. Submerge yourself in a warm Epsom salt bath to alleviate tension headaches or soothe abdominal cramps. Tired and sore feet will also benefit from the therapeutic warmth of an Epsom salt.
Besides pain and muscle relief Epsom salt also:
Helps nerves function properly
Helps prevent hardening of arteries and blood clots
Relieves constipation
Eases stress and relaxes the body
