Swanson Himalayan Crystal Salt Combo is the perfect collection for easy use and handy refills. Endorsed by Dr. Barbara Hendel, the founder of the European crystal salt movement, this is the only real Himalayan Salt in America of its kind. As the ancient seas evaporated and the Himalayan Mountains rose from the earth, ribbons of pure crystal salt were stretched throughout the rock. Its structure, mineral composition and purity was thus preserved to this day. This crystal salt is finely ground and 100% pure. It's more pure than refined table salt; it's more pure and wholesome than sea salt or rock salt.
