Montmorillonite

**Semantic type:** Pharmacologic Substance

**Definition:** A subclass of smectite and a natural aluminomagnesium silicate clay, with potential protective effect for the digestive tract mucosa, and anti-inflammatory and anti-diarrheal activities. Although the exact mechanism of action has yet to be fully elucidated, upon administration, montmorillonite may adsorb bacteria, bacterial enterotoxins, viruses and other potentially diarrheagenic substances. It may also bind to mucin and modify mucus properties, thereby enhancing the mucus barrier function.
