HelloPharmacist Scorecard of Slippery Elm Extract by Oregon's Wild Harvest
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
Slippery elm is the one active ingredient in this liquid extract, and it comes from the inner bark of the slippery elm tree. Its mucilage is the component that gives the extract its slippery, gel-like quality, and it is also the part linked to possible effects on drug absorption.
The other ingredients listed are inactive: alcohol and distilled water.
Does it work?
Couldn't assess
The evidence for slippery elm is not established in the data we hold. Our ratings for cancer, constipation, cough, inflammatory bowel disease (IBD), and diarrhea are all listed as insufficient reliable evidence to rate, so we cannot tell you whether it works for any of these uses.
How safe is it?
Well-documented data
Slippery elm is generally well tolerated for short-term use, but the high-quality safety data behind that picture is limited. Topical exposure to slippery elm or its oleoresin has been linked to contact dermatitis and urticaria (hives), and the pollen is noted as an allergen.
For pregnancy, there is not enough reliable safety data to know either way, and some sources caution against using it. For breastfeeding, there is too little information on safety, so caution is advised.
Please talk with your doctor or pharmacist for advice that fits your situation.
Meds to double-check
Moderate interaction found
Double-check any oral medication, since slippery elm carries a Moderate interaction with oral drugs as a class, which may reduce how much of the drug your body absorbs. This is the only drug type documented for this product.
Your own doctor or pharmacist can tell you whether the timing of your doses needs to change.
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 be of interest to people looking into it for a general purpose, though the evidence for its uses is not established in our data. If you take any oral medication, you should be careful, because the mucilage may reduce how well that drug is absorbed.
Talk it over with your own doctor or pharmacist before you start, especially if you are pregnant, breastfeeding, or have a pollen allergy.
Educational only — not medical advice; always confirm with your pharmacist. Our editorial policy · How we use AI
