Slippery Elm Bark usually grows on high land and dry soil. It has a brown trunk and rough, gray-white bark branches. The Reddish brown fruits grow in clusters with each consisting of a single seed visible in the center of the fruit. The Slippery Elms are tall flowering trees that can grow up to 100 feet tall with a canopy of branches. The soft inner bark has a smooth slippery texture when harvested that becomes thick and gooey when mixed with water. Slippery Elms are native to Eastern and Central US and into Canada. The Native Americans had many uses for this bark such as: wounds, boils, ulcers and inflamed eyes.
