Epsom Salt for Muscle Cramps

Thomas Onwhyn, 1857

Epsom salt, or magnesium sulfate, is a naturally occurring mineral commonly used in farming, gardening, bath salts and aquariums. Epsom salt is also used in natural medicine as a laxative, to soothe tired and aching muscles and joints, and to treat eclampsia, genital herpes, arrhythmia, fibromyalgia and preterm labor.

Epsom Salt to Treat Muscle Cramps


  • Add 1 cup of Epsom salt to a warm bath and soak for 30 minutes.

Why It Works

The magnesium in Epsom salt relaxes the muscles and reduces inflammation. The body also absorbs some magnesium while soaking, which can lead to relaxed and elevated mood.


Use warm, not hot water to prevent burns. Please consult your healthcare provider if your muscle cramps persist, as they could indicate a severe medical problem such as thrombosis, fibromyalgia or embolism.
