HelloPharmacist Scorecard of Slippery Elm by Herbal Terra

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: certified organic Slippery Elm (Ulmus rubra) dried bark liquid extract. It's been processed into a liquid form, which means the bark's active compounds are dissolved and ready to use.

The only other ingredient listed is menstruum, which is an inactive component used to extract and preserve the herb.

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 that slippery elm works for the purposes it's commonly used for—cough, constipation, diarrhea, inflammatory bowel disease, or cancer. The data rates all of these as insufficient reliable evidence to rate.

That doesn't mean the herb is ineffective; it means high-quality studies backing its use for these conditions aren't in our database.

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 for short-term use, but high-quality safety data are limited. The main concerns we know about are contact dermatitis and urticaria (hives) if you're exposed to slippery elm topically or inhale its pollen—so if you're sensitive to tree pollens or have had skin reactions to other herbal extracts, be cautious.

There isn't enough reliable data on safety during pregnancy or breastfeeding. If you're pregnant or nursing, talk with your pharmacist or doctor before taking this product.

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 Herbal Terra's Slippery Elm, check all of your oral medications in the interaction search tool on this page. The mucilage in slippery elm can moderate how quickly or completely your body absorbs drugs taken by mouth, and the list of potentially affected medications is long.

If you can't check a specific medication, ask your pharmacist.

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 generally tolerated, but the evidence for what it actually does is thin. The bigger concern is that it may slow how your body absorbs oral medications—and it could affect a lot of them.

If you're on any medications, check them against the interaction tool before you start, and space out doses with your other oral drugs. Ask your pharmacist if you're not sure.

Slippery Elm by Herbal Terra: Common Questions

Does Slippery Elm by Herbal Terra interact with any medications?
Yes. Based on its ingredients, 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?
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 stop my other medications from working?
It's possible. Slippery elm can slow your body's absorption of oral drugs, which may lower the amount of medication that gets into your bloodstream. This is why you need to check your specific medications and space doses apart. Whether it actually affects *your* meds depends on what you're taking.
Is slippery elm safe to take long-term?
We don't have enough high-quality data to know. It's generally well tolerated for short-term use, but long-term safety isn't well studied. If you're thinking about using it regularly, talk with your pharmacist or doctor.
Can I take slippery elm if I'm pregnant or breastfeeding?
There isn't enough reliable safety information either way. The data isn't there to say yes or no. If you're pregnant or nursing, talk with your doctor or pharmacist about whether this product is right for you.
Can slippery elm cause an allergic reaction?
Yes. Contact dermatitis and hives have been reported after exposure to slippery elm or its pollen. If you have a tree pollen allergy or have had skin reactions to herbal products before, let your pharmacist know.
What does slippery elm actually do?
It's traditionally used for cough, constipation, diarrhea, and digestive inflammation, but the research we have on file rates all of these as insufficient evidence to rate. We don't have solid proof it works for any of them.
