Slippery elm bark is a demulcent. This means that it is capable of soothing the lining of the stomach and intestines and reducing irritation. Slippery elm may be helpful for treating occasional heartburn, also known as acid reflux. It’s also considered an herbal remedy for gastroesophageal reflux disease (GERD).
GERD is a chronic disease that occurs when stomach acid flows back into esophagus and irritates the lining.
