Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Slippery elm bark (Ulmus rubra) has a long history of use in traditional herbal medicine, especially among Native American tribes and later by early European settlers in North America. It is primarily valued for its mucilaginous (gel-like) properties when mixed with water, which is believed to coat and soothe the mucous membranes of the digestive tract. Traditional herbalists have recommended slippery elm for the relief of symptoms associated with overacidity, such as heartburn, gastritis, and indigestion, under the rationale that its soothing mucilage forms a protective barrier against irritation caused by excess stomach acid.
Scientific research on slippery elm’s effects on overacidity is limited. While small studies and anecdotal evidence suggest it may provide symptomatic relief for some gastrointestinal conditions, high-quality clinical trials are lacking. The evidence supporting its use is mainly based on its physical characteristics and centuries of traditional use rather than robust scientific validation. The FDA recognizes slippery elm as generally safe when used appropriately, but does not endorse it for any medical indication. Overall, its reputation as a remedy for overacidity is rooted in tradition, with a moderate level of support from historical usage but minimal direct clinical evidence.
