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.

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.

This product contains one active ingredient: slippery elm bark extract. Slippery elm is the inner bark of a tree, traditionally used to coat and soothe the digestive tract because of its mucilage content—a thick, slippery substance that creates a protective layer.

The other ingredients are vegetable glycerin, distilled water, and organic grain alcohol, which are used to extract and preserve the active ingredient in liquid form.

Does it work?

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 isn't established in our data for any of the conditions listed—cancer, constipation, cough, inflammatory bowel disease, and diarrhea all show insufficient reliable evidence to rate its effectiveness. That doesn't mean it doesn't work; it means the available studies aren't strong enough to make a firm claim either way.

If you're considering it for a specific condition, ask your pharmacist what the current evidence shows and whether it's right for you.

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 good safety data are limited. Some people have reported contact dermatitis (skin irritation) and urticaria (hives) from touching slippery elm or its pollen, and slippery elm pollen is a known allergen, so avoid it if you're sensitive.

There isn't enough reliable safety data during pregnancy, so caution is advised. There's also too little information on safety while breastfeeding.

Talk with your doctor or pharmacist before using this product if you're pregnant or nursing.

Side effects, ingredient by ingredient Slippery Elm

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.

If you take any oral medications—tablets, capsules, or liquids by mouth—you should check them here before starting slippery elm. The mucilage in the extract can slow how your body absorbs drugs, and this is a Moderate-severity interaction that affects a very large number of medications.

Spacing your doses out by a couple of hours usually prevents this problem.

Check your own medication Run your meds through the checker above

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 worth considering if you're interested in traditional digestive support—but the evidence isn't strong yet. The main thing to watch is timing: separate it from your other oral medications by at least 2 hours to avoid slowing their absorption.

If you're pregnant, breastfeeding, or have a history of allergies to tree pollen, check with your pharmacist first.
