Epsom salt takes its name from the town of Epsom in Surrey, England, where mineral-rich spring water became famous in the 1600s. Visitors travelled there to “take the waters”, and the magnesium sulphate found in the springs eventually became known as Epsom salt.
Centuries later, Epsom salt remains closely associated with bathing and self-care. That long tradition of mineral bathing is why it fits so naturally alongside the herbs and aromatic oils in our own Thai-inspired bath ritual.
