Epsom salts were discovered in Epsom, Surrey, England by a farmer in 1618 whose cows would not drink from a particular fresh water source. He also discovered that water from this mineral-rich spring helped to heal rashes and small wounds faster.

Epsom salts contain magnesium sulphate, which can reduce inflammation and increase endorphins, which act as the body’s natural painkillers. This form of magnesium can be absorbed by the skin which has been shown to help with various ailments. The salts are antibacterial, and antifungal so can help with avoiding and treating minor infections of the skin.

Epsom salt baths can improve blood circulation and help with the elasticity of arteries. They can also help to protect against heart disease and strokes by reducing blood clots and lowering the blood pressure. However, people with existing heart problems should avoid Epsom salt baths.

Epsom salt baths are particularly helpful for athletes during recovery from intense physical exertion as they can help to reduce inflammation and muscle pain and stiffness.

Twenty minutes soaking in one Epsom salt bath a week (one to four cups of Epsom salts per bath) is sufficient for enough magnesium to be absorbed.  Too much magnesium absorption can lead to symptoms like abdominal cramps, diarrhoea, lethargy, muscle weakness or nausea. Impaired kidney function can slow down the elimination of excess magnesium.

Magnesium deficiency can impair vitamin D function, and high-dose vitamin D can exacerbate a magnesium deficiency. In these cases, an Epsom salt bath once a week can help to improve magnesium levels in the body.
