Epsom salt is also known as magnesium sulphate. It’s a chemical compound made up of magnesium, sulphur, and oxygen. It gets its name from the town of Epsom in Surrey, England, where it was originally discovered. Despite its name, Epsom salt is a completely different compound than table salt. It was most likely termed salt because of its chemical structure. It has an appearance similar to table salt and is often dissolved in baths, which is why you may also know it as bath salt. While it looks similar to table salt, its taste is distinctly different. Epsom salt is quite bitter and unpalatable. Some people still consume it by dissolving the salt in water and drinking it. However, due to its taste, you probably don’t want to add it to food.
