HelloPharmacist Scorecard of Slippery Elm 400 mg by Solaray

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: slippery elm inner bark at 400 mg per capsule. Slippery elm is a tree bark that's been used traditionally to soothe digestive discomfort.

The capsule also contains inactive ingredients — cellulose and rice extract blend — that serve as fillers and binding agents.

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: Herbal support for digestive and throat health.
  • We looked for evidence on: Constipation, Cough, Diarrhea, Irritable bowel syndrome (IBS), Pharyngitis, 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, Diarrhea, Irritable bowel syndrome (IBS), Peptic ulcers, and more.

The evidence we hold shows insufficient reliable evidence to rate slippery elm for cancer, constipation, cough, inflammatory bowel disease, or diarrhea. In other words, we don't have strong clinical data backing its use for any of these purposes right now.

If you're considering it for a specific condition, talk with your pharmacist or doctor about what the current evidence supports.

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 high-quality safety data are limited. The most common concern is allergic reaction — slippery elm pollen is an allergen, and contact dermatitis and hives have been reported after skin exposure to the herb or compounds in the bark.

For pregnancy, there isn't enough reliable safety data, so caution is advised. For breastfeeding, there's too little information to know either way, so talk with your doctor or pharmacist before using this product if you're nursing.

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 Solaray Slippery Elm, run a check on any oral medications you take — prescription or over-the-counter. Slippery elm's mucilage may slow their absorption and reduce their effectiveness.

The interaction is Moderate severity and applies broadly to oral drugs, so it's worth confirming your specific medications won't be affected.
