Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Slippery elm bark (Ulmus rubra) has a long history of traditional use in North American herbal medicine, primarily by Indigenous peoples and later by European settlers. It is most commonly used as a demulcent—a substance that forms a soothing film over mucous membranes—and has been employed for soothing sore throats, coughs, and various digestive complaints, including indigestion and heartburn. The mucilage in slippery elm bark is believed to coat the lining of the esophagus and stomach, providing relief from irritation and minor inflammation associated with indigestion.

Scientific research on slippery elm bark’s effectiveness for indigestion is limited. A few small studies and anecdotal reports suggest potential benefits, especially for symptoms like heartburn and mild gastrointestinal discomfort, but robust clinical trials are lacking. The evidence largely remains at the level of traditional use and case reports, rather than being supported by high-quality, large-scale studies. Safety profiles are generally favorable, with few reported adverse effects, particularly when used as a tea or lozenge.

In summary, while slippery elm bark is traditionally used to soothe digestive discomfort, including indigestion, the scientific evidence supporting its effectiveness is weak. The rating of 2 reflects that there is historical precedent and some plausible mechanism (mucilage coating), but little rigorous scientific validation.
