Slippery Elm
Slippery Elm Bark (Ulmus rubra)
Mucilaginous herb that soothes and coats the digestive tract, providing relief for GERD, gastritis, and irritated gut lining.
Slippery Elm bark contains mucilage that forms a soothing gel when mixed with water. This gel coats and protects irritated mucous membranes throughout the digestive tract. Traditional remedy for heartburn, gastritis, IBS, and sore throat. FDA-approved as a safe demulcent. Works mechanically rather than pharmacologically.
Mechanisms of Action
Mucilage Coating

Best Form
Inner bark powder (mix with water to form gel)
Alternatives: Capsules, Lozenges (for throat), Tea
Powder mixed with water is most effective as it forms the soothing gel. Lozenges good for sore throat.

Ahuja A et al. • Current gastroenterology reports (2019)
“This landscape of popular treatments nevertheless raises several interesting mechanistic hypotheses and compelling opportunities for future research.”
Key Findings:
- Systematic review examining Slippery Elm efficacy
- Published in Current gastroenterology reports (2019)
- Further research warranted to confirm findings
Zick SM et al. • Journal of alternative and complementary medicine (New York, N.Y.) (2006)
“Essiac does not appear to improve HR-QOL or mood states.”
Key Findings:
- This might be attributed to the fact that the group of users comprised younger women with more advanced stages of breast cancer, and both of these subgroups of patients have been shown to be at a significantly increased risk for negative mood states and/or a decreased sense of well-being.
- Essiac does not appear to improve HR-QOL or mood states.
- Future studies are needed to determine whether other clinical outcomes, such as cancer reoccurrence, are affected by Essiac.

Tinsley G et al. • Journal of dietary supplements (2019)
“These results indicate that consuming a commercially available dietary supplement that purportedly provides detoxification and body composition benefits is apparently safe in healthy young adult females but does not provide any beneficial effects for body composition or gastrointestinal symptoms.”
Key Findings:
- Body composition, waist circumferences, symptoms of gastrointestinal distress, and blood safety markers were evaluated before and after supplementation.
- Twenty-two participants completed the study, and data were analyzed via two-way mixed ANOVA and t tests.
- These results indicate that consuming a commercially available dietary supplement that purportedly provides detoxification and body composition benefits is apparently safe in healthy young adult females but does not provide any beneficial effects for body composition or gastrointestinal symptoms.
