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.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

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
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Slippery Elm product and its label doesn't state a use — see Slippery Elm's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

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.

The evidence, ingredient by ingredient Slippery Elm

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

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
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Slippery Elm.
  • The most serious interaction on file is rated Moderate.
  • For scale: 2,023 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

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.
