Bentonite Clay is a mineral deposit that makes an excellent face pack, body treatment or bathing agent. Anhydrous bentonite clay swells up and becomes porous when mixed with water. This process causes it to become electrically charged drawing out and attaching itself to toxins. Our Bentonite clay is of the finest quality. This Bentonite clay is air dried and is 100% natural.
