A 100% natural, velvety fine, soft gray clay ideal for external use (it’s very detoxifying). Our sodium bentonite clay contains over 61% silica, 25–35 trace minerals—and absolutely no additives. Mix it with water or oil for face masks, or craft poultices to soothe irritated, sore skin. Sodium bentonite absorbs water and soaks up impurities like a sponge! It can also increase energy flow where it’s applied. Our silky sodium bentonite clay comes from the vast, sun-dried volcanic ash deposits of Wyoming.
