HelloPharmacist Scorecard of Slippery Elm Bark by Mountain Meadow Herbs
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 product has one active ingredient, slippery elm bark extract. Our data notes that the inner bark contains mucilage, which is the substance behind its absorption concern.
The inactive ingredients listed are vegetable glycerin, distilled water, and organic grain alcohol.
Does it work?
Couldn't assess
Our data rates slippery elm as Insufficient Reliable Evidence To Rate for cancer, constipation, cough, inflammatory bowel disease (IBD), and diarrhea. That means the evidence for these uses isn't established in the data we hold, not that it has been shown not to work.
How safe is it?
Well-documented data
Our safety notes describe slippery elm as generally well tolerated for short-term use, though high-quality safety data are limited. Topically, it can cause contact dermatitis (a skin reaction from contact), and its pollen is an allergen; contact dermatitis and hives (urticaria) have been reported.
For pregnancy, reliable safety data are insufficient, and some sources caution against use while pregnant. There isn't enough data to know either way, so talk with your doctor or pharmacist.
For breastfeeding, there is too little information, so caution is advised, and no lactation rating is on file.
Meds to double-check
Moderate interaction found
Oral drugs (medications you swallow) are the drug type to double-check, rated Moderate. Slippery elm's mucilage may reduce how well they are absorbed.
Confirm your specific prescriptions with your own doctor or pharmacist before taking this product.
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.
Slippery elm may interest people exploring it for a general purpose, but the evidence for its uses is not established in our data. If you take oral medications, the absorption concern is the main point to discuss.
Talk it over with your own doctor or pharmacist before starting, especially if you are pregnant or breastfeeding.
Educational only — not medical advice; always confirm with your pharmacist. Our editorial policy · How we use AI
Assessment coverage: 1 of 1 active ingredient matched to our full ingredient reviews (monographs). Based on the product label dated May 23, 2024.
This Scorecard evaluates available label information, ingredient evidence, and known medication-safety considerations. It does not independently verify product identity, purity, potency, contamination, or manufacturing quality. How these ratings are computed
