Well, bath salts are good things to use because bath salts are usually inorganic solid products designed to be added to a bath, either to improve cleaning, provide a medical improvement, improve the experience of bathing, or serve as a vehicle for cosmetic agents. Bath salts have been developed which mimic the properties of natural mineral baths or hot springs.
