Slippery Elm
Parts Used & Where Grown
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 preparations.
How It Works
The mucilage of slippery elm, found in the inner bark, gives it the soothing effect for which it is known.1 In people with heartburn, the mucilage appears to act as a barrier against the damaging effects of acid on the esophagus. It may also have an anti-inflammatory effect locally in the stomach and intestines. This soothing effect may also extend to the throat. Clinical research, verifying these effects in humans has not been conducted.
