This widely used material is characterized by its interesting properties, which include bitterness and crystalline structure.

Epsom salt is used in a number of products and processes. It is commonly used in agriculture as a fertilizer and soil additive to help improve plant nutrition, as it is an excellent source of magnesium and sulfur for plants. In the cosmetics industry, it is often used as a key ingredient in bath salts and exfoliants due to its beneficial effects on the skin, for example helping to soften it and remove dead skin cells. In the pharmaceutical industry, epsom salt is used in the manufacture of medicines, for example as a laxative or to treat certain skin conditions. When added to a bath, epsom salt has a relaxing effect and helps to relax the muscles.
