HelloPharmacist Scorecard of Ulmus Spp. Slippery Elm by Wise Woman Herbals

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (3 mL) without saying how much of each component you get.

This is a one-ingredient product: slippery elm inner bark in liquid form. The inactive ingredients are spring water, alcohol, and glycerin.

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 well established yet. Our data shows insufficient reliable evidence to rate how well it works for cancer, constipation, cough, diarrhea, or inflammatory bowel disease (IBD).

That doesn't mean it doesn't work — it means the research so far hasn't been solid enough to make a clear claim.

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, but high-quality safety data are limited. The pollen can trigger allergies in some people, and direct contact with slippery elm or compounds in the bark can cause a rash (contact dermatitis) or hives (urticaria) in those who are sensitive.

During pregnancy, there isn't enough reliable safety data, so caution is advised — talk with your doctor or pharmacist before using it. The same goes for breastfeeding: there's too little information on safety, so personalized guidance is important.

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.

Check any oral medications you take — slippery elm's mucilage may slow their absorption and reduce how well they work. Because 2,003 individual drugs could potentially be affected, running your exact medications through the checker below is important before you start.

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 is generally well tolerated for short-term use, but the main thing to watch is how it may slow the absorption of your other oral medications. If you take any prescription or over-the-counter drugs, check them against the interaction tool on this page before starting.

Ulmus Spp. Slippery Elm by Wise Woman Herbals: Common Questions

Does Ulmus Spp. Slippery Elm by Wise Woman Herbals interact with any medications?
Yes. Based on its ingredients, Ulmus Spp. Slippery Elm 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?
Ulmus Spp. Slippery Elm contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Will slippery elm actually help with my digestive or cough issues?
The evidence isn't clear enough yet. Our data shows insufficient reliable evidence to rate how well it works for constipation, diarrhea, cough, inflammatory bowel disease, or cancer. That's not a "no" — it's that research hasn't been solid enough to make a confident claim either way.
Can I take slippery elm with my other medications?
It depends on what you take. Slippery elm may slow down how your body absorbs oral drugs, which could make them less effective. Spacing doses at least two hours apart can help, but you'll want to check your specific medications with the tool on this page first.
Is it safe for short-term use?
Slippery elm is generally well tolerated when used short-term, but high-quality safety data are limited. If you have sensitive skin, know that direct contact can cause a rash or hives, and the pollen can trigger allergies.
Can I use this while pregnant?
There isn't enough reliable safety data to know either way. Talk with your doctor or pharmacist for personalized advice — they know your situation best.
Is it safe while breastfeeding?
There's too little information on safety during breastfeeding. Check with your pharmacist or doctor before using it — they can help you weigh the pros and cons for your individual situation.
What exactly is slippery elm and why does it affect medication absorption?
Slippery elm is the inner bark of the elm tree. It contains mucilage — a thick, sticky substance that coats your digestive tract. This coating may interfere with how your body absorbs oral medications taken by mouth.
