All-Salt contains a special blend of the most commonly used pharmaceuticals (see Ingredients) – trace concentrations that accumulate in the body over time to heal a variety of ailments. We harvest our medicinal salt from the brackish waters of the Artesian Slough, which channels treated wastewater (known to contain a variety of pharmaceutical compounds) from the San Jose/Santa Clara Water Pollution Control Plant to the South San Francisco Bay.
