Bentonite

Bentonite attracts and neutralizes poisons in the intestinal tract. Studies show that it can help to eliminate diarrhea resulting from food allergies, food poisoning, mucus colitis, spastic colitis, viral infections, stomach flu, and parasites. Bentonite is naturally absorbent and gentle on the system.
