This is one of our favorite sea salts due to its beautiful pale pink color with mineral particles of darker and different colors. This salt contains more than 50 natural trace minerals essential to human health, including natural iodine. No anti-caking agents are used in this all natural salt. This salt is beautiful when used in bath salts and other bath products. This salt is edible and is found in many supermarkets in the gourmet salts section; it provides many of the minerals not found in ordinary table salt. Salt cures aren't new. In the early 19th Century, sick people traveled to rudimentary spas such as French Lick Springs in Indiana and Big Bone Lick, Kentucky, to soak in salt springs. Today's more luxurious spas offer salt baths, glows, rubs and polishes to exfoliate dead skin, stimulate circulation and relieve stress. The ordinary table salt that most of us eat is too refined; it lacks the minerals we need. Also, yellow prussiate of soda and other additives and preservatives are added to prevent caking, dextrose is even added to improve flavor. About half of all table salt is supplemented with potassium iodide, which wards off goiter. Our pink salt contains 50 natural occurring trace minerals like calcium, potassium, sulphur, magnesium, iron, phosphorus, manganese, copper, iodine and zinc. Our pink salt is Kosher-certified and is of U.S. origin. INCI: Sodium chloride
