A variety of suppliers on Amazon.com and eBay.com sell bentonite in dry and wet forms. Numerous health food stores and natural remedy supply stores such as The Vitamin Shoppe also sell bentonite.
Natural health practitioners use bentonite to detoxify the skin and body. It can be applied as a paste to the skin or taken internally via a powder, drink mix or pill. Users of bentonite clay claim it treats eczema, psoriasis, digestive issues and dental problems.
The United States, France and Italy are the main locations where bentonite clay is harvested. The clay was named after the location of the largest deposit, Fort Benton, Wyoming.
