Natural clay, especially "Bentonite Clay", has not only been used medicinally for hundreds of years by indigenous cultures around the planet, but has, in recent years, been increasingly used by practitioners of alternative medicine as a simple but effective internal cleanser to help in preventing and alleviating various health problems. Bentonite when mixed with water can be used externally on skin, gums and for facials as well as for various other internal and external applications.
Bentonite is not a mineral, but a commercial name for "montmorillonite", the active mineral in many medicinal clays.
