What Is SLIPPERY ELM?

Supplement

Slippery elm (Ulmus rubra) is a tree native to North America whose inner bark contains mucilage, a gel-forming polysaccharide that provides demulcent and emollient properties. The mucilage coats and soothes mucous membranes, making it traditionally used for gastrointestinal disorders, sore throat, cough, and inflammatory conditions. It works by forming a protective layer over irritated tissues and may support gut barrier function.
