HelloPharmacist Scorecard of Slippery Elm Inner Bark by Gaia 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 0 of its 3 active ingredients.

This liquid contains 3 ingredients. The active component is slippery elm inner bark extract, a demulcent (soothing agent) traditionally used for digestive and throat comfort.

The extract is suspended in water and 25–35% pure grain alcohol, which acts as both a solvent and preservative.

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 have on file doesn't establish that slippery elm works for cancer, constipation, cough, inflammatory bowel disease, or diarrhea — the ratings across all these uses are insufficient. That doesn't mean it doesn't help; it means high-quality studies backing it up aren't yet in our data.

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 rigorous safety data are limited. Contact dermatitis and allergic reactions (urticaria) have been reported, particularly with topical exposure or if you're sensitive to slippery elm pollen.

During pregnancy, there isn't enough reliable safety data — talk with your doctor or pharmacist about whether it's right for you. For breastfeeding, too little information exists on safety, so caution is advised; check with your doctor or pharmacist before use.

Side effects, ingredient by ingredient Slippery Elm

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check

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 you take this product, double-check your oral medications — slippery elm may slow their absorption and reduce how well they work. Altogether, these interactions span 2,023 individual medications, so use the interaction checker on this page and confirm with your own doctor or pharmacist.

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 Inner Bark is generally well tolerated for short-term use, but its mucilage can slow oral drug absorption — a real concern if you take medications by mouth. If you're on any oral medications, check them against the interaction tool and talk with your doctor or pharmacist before adding this product.

Effectiveness for its common uses hasn't been established in our data.

Yes. Based on its ingredients, Slippery Elm Inner Bark has a known interaction with 2,022 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Slippery Elm Inner Bark contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm pregnant?
There isn't enough reliable safety data on slippery elm during pregnancy to know either way. Talk with your doctor or pharmacist about whether it's right for you.
Is slippery elm safe while breastfeeding?
There's too little information on safety during breastfeeding to say. Check with your doctor or pharmacist for personalized advice.
What is slippery elm supposed to do?
Slippery elm is traditionally used as a demulcent — a soothing agent for the throat and digestive tract. We don't have strong evidence on file that it works for specific conditions like cough, constipation, or inflammatory bowel disease.
Can I take this with all my medications?
Not without checking first. Slippery elm's mucilage may slow down how your body absorbs oral medications, which could make them less effective. Separate doses by at least two hours, and run your specific medications through the interaction tool on this page. Then confirm with your doctor or pharmacist.
What's in this liquid besides the slippery elm?
Water and 25–35% pure grain alcohol, which preserves and dissolves the extract. There are no other inactive ingredients.
Are there any side effects I should know about?
Short-term use is generally well tolerated. Contact dermatitis and allergic reactions have been reported, especially if you're sensitive to slippery elm pollen. Stop and check with your pharmacist if you develop a rash or reaction after taking it.
