HelloPharmacist Scorecard of Slippery Elm by Hawaii Pharm

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 liquid contains one active ingredient: certified organic Slippery Elm extract. The extract is made from the inner bark of the slippery elm tree.

The product also includes vegetable palm glycerin and pharmaceutical-grade alcohol as inactive ingredients (the carriers that make up the liquid).

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 we hold doesn't establish how well slippery elm works. It's traditionally used for cough, constipation, diarrhea, and inflammatory bowel disease, but reliable studies are lacking — the data rates all of these uses as insufficient evidence to make a recommendation.

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 when used short-term, though high-quality safety data are limited. Some people have reported contact dermatitis (a skin rash) or itching after touching slippery elm or its pollen, and a few have had hives.

There isn't enough reliable data to know whether it's safe during pregnancy or breastfeeding. If you're pregnant or nursing, talk with your pharmacist or doctor before starting it.

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.

Any oral medications — pills, capsules, or liquids you swallow — may be affected by slippery elm. Space your doses at least two hours apart from other drugs, and use the medication checker on this page to confirm your prescriptions before you start.

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 is a traditional herbal remedy, but we don't have strong evidence it works for the conditions it's used for. The main thing to watch is its potential to slow how your body absorbs oral medications — space doses apart and check your prescriptions with us first.

If you're pregnant, nursing, or have a history of skin reactions to plants, discuss it with your pharmacist.
