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.
What’s inside
Full disclosure
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
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.
How safe is it?
Well-documented data
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.
Meds to double-check
Moderate interaction found
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.
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 400 mg is a single-herb supplement that's generally well tolerated short-term, but the evidence for its effectiveness isn't established in our data. The main concern is that it may slow how your body absorbs oral medications, affecting up to 2,003 individual drugs.
Before you start, check your medications with the tool on this page — and if you're pregnant or breastfeeding, talk with your pharmacist for personalized guidance.
