HelloPharmacist Scorecard of White Slippery Elm Bark by TerraVita

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: White Slippery Elm Bark Glycerite Liquid Extract. Slippery elm is the inner bark of a tree, prepared here as a liquid extract in glycerin, which acts as a preservative and carrier.

The inactive ingredient in this product is glycerin.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Slippery Elm's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: digestive and throat health.
  • We looked for evidence on: Cough, Pharyngitis, Constipation, Diarrhea, Irritable bowel syndrome (IBS), Peptic ulcers — and 4 related terms.
  • The closest evidence on file: Slippery Elm is rated "Insufficient Reliable Evidence To Rate" for Constipation (Natural Medicines).
  • Also on file: Slippery Elm is rated "Insufficient Reliable Evidence To Rate" for Cough, Inflammatory bowel disease (IBD), Diarrhea, Irritable bowel syndrome (IBS), and more.

The evidence supporting slippery elm for any use is insufficient to rate right now. Our data shows that claims about it for cancer, constipation, cough, diarrhea, and inflammatory bowel disease (IBD) don't yet have reliable evidence behind them.

That doesn't mean it doesn't work — it means the science hasn't caught up yet. If you're considering this for a specific condition, talk with your pharmacist or doctor about whether there's a better-studied option.

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 high-quality safety data are limited, so we don't know as much as we'd like about long-term safety. Topically, slippery elm can cause contact dermatitis (skin irritation).

The pollen is an allergen, and some people have reported contact dermatitis or urticaria (hives) after exposure to slippery elm or compounds in the bark. If you have a known tree pollen allergy, be cautious.

There isn't enough reliable data on safety during pregnancy or breastfeeding, so talk with your doctor or pharmacist before using this product if you're pregnant, planning to become pregnant, or nursing.

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 oral medications — any tablet, capsule, or liquid you swallow — space this product at least two hours apart from them. Slippery elm's mucilage can slow how your body absorbs drugs, which may make them less effective.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Slippery elm is generally well tolerated short-term, but the evidence for what it actually does isn't established yet. The main thing to watch is spacing it away from your oral medications — at least two hours apart — because it may slow their absorption.

If you take regular medications, check them with our tool first, and run any questions by your pharmacist.
