  • Preventing your body’s release of a chemical called prostaglandin that causes inflammation

  • Blocking toxins produced by bacteria such as E. coli

  • Killing other bacteria that cause diarrhea 

The active ingredient, bismuth subsalicylate, also has antacid properties that can help to decrease heartburn, nausea and upset stomach.
