I buy one of these 8lb bags every other week. When I need some relief for my muscles or after a hard workout or yoga session, or if I just need to relax, I use about 2-4 pounds at a time in a hot bath. Sometimes I'll add essential oils to the bag to let it soak up, but I never waste my money on the Epsom salts that are scented, since most of the time it's an artificial fragrance and smells insanely gross. These are perfect and natural and the only kind I buy. It's less than $6 a bag, too. A worthy investment!
