NOW Foods Slippery Elm Powder provides pure powdered inner bark of Ulmus rubra in a versatile 4 oz powder — the preferred format for making traditional slippery elm gruel, poultices, and therapeutic tea preparations that maximize mucosal contact time and soothing benefit. When mixed with warm water, slippery elm powder forms a thick, mucilaginous gel that coats and soothes irritated mucous membranes throughout the digestive tract — providing relief for GERD, esophagitis, gastritis, IBS flares, and inflammatory bowel conditions. The powder can be stirred into water or oatmeal, made into a soothing porridge-like gruel, or added to smoothies. NOW Foods provides pure inner bark powder without additives, manufactured in their GMP-certified facility with botanical identity verification. A time-honored herbal remedy for digestive mucosal healing.
