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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 3 active ingredients.

This liquid contains 3 ingredients: distilled water, organic grain alcohol, and slippery elm bark extract. The active component is the slippery elm bark extract—an herbal preparation from the inner bark of the slippery elm tree, traditionally used to coat and soothe the digestive tract.

The grain alcohol is used to extract and preserve the herb; it's not meant as an active ingredient itself.

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 isn't established in the data we hold. For constipation, diarrhea, inflammatory bowel disease, cough, and cancer, the data shows insufficient reliable evidence to rate its effectiveness.

If you're considering it for one of these reasons, talk with your doctor or pharmacist about whether the available research supports it for your situation.

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, though high-quality long-term safety data are limited. The main adverse effects reported are contact dermatitis and urticaria (hives) when the herb or its pollen touches skin or is inhaled—not typically a concern with a swallowed liquid extract, but worth knowing.

For pregnancy, there isn't enough reliable safety data; some sources caution against it. For breastfeeding, there's too little information to know either way, so talk with your doctor or pharmacist if you're 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.

Before taking this product, check with your own doctor or pharmacist about any oral medications you take—pills, capsules, or liquids by mouth. Slippery elm's mucilage may slow their absorption and reduce how much gets into your system.

Spacing doses apart usually helps, but the right timing depends on your specific drugs and your health.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Slippery Elm Bark is generally well tolerated, but its main risk is slowing absorption of oral medications—a moderate interaction affecting a large number of drugs. If you take any oral medications, check your specific drugs with your own doctor or pharmacist before starting this product and ask about spacing doses.

If you're pregnant or breastfeeding, discuss it with your healthcare provider first, since safety data are limited.
