HelloPharmacist Scorecard of Slippery Elm Bark by Baar Nature's Blessing
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This capsule contains one active ingredient: slippery elm inner bark. The capsule itself is made from hypromellose (a plant-based coating), along with stearic acid and microcrystalline cellulose as inactive ingredients.
Does it work?
Couldn't assess
The evidence for slippery elm isn't established in the data we hold. Studies haven't given us reliable answers yet on whether it works for cancer, constipation, cough, diarrhea, or inflammatory bowel disease (IBD).
How safe is it?
Well-documented data
Slippery elm is generally well tolerated when used short-term, though high-quality safety data are limited. The pollen and extracts can trigger allergic reactions in some people — contact dermatitis (skin rash from direct contact) and hives have been reported.
Not enough reliable data exist on safety during pregnancy or breastfeeding, so caution is advised if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before you take Slippery Elm Bark, check all your oral medications (any drug you swallow) with the search tool below. The mucilage in slippery elm may slow their absorption and lower their levels in your blood, which could affect how well they work.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you're considering slippery elm for digestive or throat comfort, talk with your pharmacist first — especially if you take any oral medications. The mucilage in it may interfere with how your drugs are absorbed.
Pregnant or breastfeeding? Check with your doctor or pharmacist before starting.
