  • Slippery Elm Bark
    By Vital Plan
    Reviewed by Bill Rawls, MD
    Medical Director of Vital Plan

    Ulmus rubra, the slippery elm, is a tree native to North America.

    The inner bark has long been used in traditional medicine, particularly by native North Americans, to support digestion and the body’s immune response.

    Slippery elm bark is best-known for its mucilage, a soft fiber with benefits for the entire GI tract. It is also a source of phytosterols, minerals, antioxidants, vitamins, and beneficial fatty acids.

    Benefits of Slippery Elm Bark*

    Ulmus rubra is used internally to:

    • Soothe the gastrointestinal tract
    • Support the stomach’s natural lining
    • Promote regular digestion
    • Normalize elimination
    • Support respiration and ease cough
    • Soothe sore throat
    • Promote a balanced microbiome
    • Support healthy cholesterol levels

    How Slippery Elm Works*

    When consumed with liquid, the mucilage in slippery elm thickens and becomes viscous, coating the mucous membranes along the GI tract to help support healthy absorption of nutrients. Research from the University of Maryland Medical Center suggests that slippery elm also causes an increase in natural mucous secretion.

    Slippery elm’s mucilage also has a bulking effect that can promote digestion and regularity. At the same time, Ulmus rubra appears to absorb water in the colon, potentially helping normalize watery bowels. Interestingly, slippery elm has been shown to be useful for occasional constipation and diarrhea, as well as reducing occasional stomach discomfort, bloat, and gas.

    Ulmus rubra may also soothe the stomach lining, and some lozenge manufacturers include slippery elm in their formulas to soothe throat discomfort.

    Side effects: This herb may slow the absorption of orally administered drugs. It is recommended to take slippery elm at least 2 hrs apart from over the counter or prescription drugs.

    Should be taken with at least 8 oz of water.

    Do not take slippery elm if you are pregnant or plan to become pregnant.
