Actually, the liquid Bentonite is the one you want. If you can only find powdered Bentonite you should hydrate it before using it. I think you can order directly from Yerba Prima...I think it's www.yerba.com. If it doesn't come up do a search for Yerba Prima...you want the Great Plaines Detox liquid bentonite...and they also have psyllium and brushes for dry skin brushing if you need them too.
