For generations, people have used Epsom salts to help heal various ailments and relieve pain from arthritis and sore muscles.  Epsom salts, also known as magnesium sulphate, is a chemical compound made up of magnesium, sulphur, and oxygen. Although the scientific evidence is limited, Epsom salts healing properties come from the high magnesium content.  Magnesium plays a key role in regulating muscle and nerve function, blood sugar levels, and blood pressure.  It also plays a role in making protein, bone, and DNA.  Here are four uses for Epsom Salt that many health care professionals recommend:

Post-Workout Recovery:

Add Epsom salt to a warm bath to help soothe muscle pain, soreness, and discomfort.  The magnesium regulates your electrolyte balance and can help deal with stored lactic acid and provide relief from soreness, inflammation, and muscle cramps.

Foot Care and Pain Relief:

Giving your feet an Epsom Salt soak (2tbs of Epsom salts to 1 quart of warm water – soak for 20 minutes) every day can help relieve sore or injured feet.

Anxiety:

People with magnesium deficiency are more likely to suffer from anxiety and insomnia, as a result some doctors will recommend an Epsom Salt bath.

Better Quality Sleep:

Epsom salt baths help people sleep better. It is felt that the baths encourage a feeling of calm, and relaxation resulting in a better quality sleep.

There seems to be some benefits of Epsom salt that many doctors recognize. Doctors do not agree of one use of Epsom salts though. There is an antidote of using Epsom salts as a laxative for treating constipation or as a way to “detox”. However ingesting Epsom salts is not a good idea.  Although magnesium sulphate is used in colonoscopy preparation, using it long-term can cause electrolyte imbalances and fluids shifts, which could cause damage to your kidneys and heart.
