The slippery elm tree is native to North America, where it still grows primarily. The inner bark of the tree is the main part used for medicinal purposes.
Slippery elm helps soothe inflamed tissues. Doctors sometimes use this herb in combination with marshmallow, cranesbill and other herbs to soothe the digestive tract. It is high in mucilage which may help reduce the irritation to the walls of the intestinal tract that can occur with diarrhea. It may also be advantageous for people with gastritis because its slippery nature soothes irritated mucus membranes of the digestive tract.
It may also have an anti-inflammatory effect in the stomach and intestines and its mucilage content appears to protect against the damaging effects of acid on the esophagus.
