Detox Dirt comprised of Montmorillonite clay used to remove the toxins from the body. It has been ingested as a nutritional supplement and detoxifier throughout the world for thousands of years. It absorbs and adsorbs toxins in the body through a process called cationic exchange. The process occurs in the gut where negatively charged clay molecules bind to positively charged toxins. The toxins are carried out of the body with the clay.
