Aztec Secret Indian Healing Clay is made of 100% bentonite green clay that has been sun-dried, so there are no fillers. It is a volcanic ash from when the Earth was formed. It is the foam residue left as the planet cooled. The foam residue formed a pure clay vein layered between white sand, near one of the lowest parts of planet Earth. When a facial or clay poultice is applied to the skin it forms a negative charge. This 1 lb. container makes between 10 and 15 masks and should be used about once a week.
