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 a single active ingredient: wintergreen herb at 450 mg per capsule. The capsule itself is made from gelatin and water.

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 Wintergreen product and its label doesn't state a use — see Wintergreen'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 wintergreen isn't established in our data. We hold insufficient reliable evidence to rate whether it works for back pain, muscle soreness, or joint pain.

That doesn't mean it doesn't work — it means the research we have access to doesn't show a clear answer yet.

The evidence, ingredient by ingredient Wintergreen

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.

Wintergreen leaf taken by mouth seems to be well tolerated in general. However, wintergreen oil — which can be present in supplements — carries real safety concerns.

The oil is extremely toxic if swallowed and can cause salicylate poisoning with symptoms like headache, ringing in the ears, and confusion. Topical wintergreen oil is generally well tolerated, but should never be covered with an occlusive (airtight) dressing, as that can lead to absorption of toxic amounts.

Wintergreen oil may also cause contact dermatitis in some people. For pregnancy, we don't have safety data on file.

For breastfeeding, wintergreen is rated likely unsafe — talk with your pharmacist or doctor before using it if you're nursing.

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Wintergreen.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 37 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 your medications before taking this product if you use warfarin (a blood thinner) or aspirin. The wintergreen can interact with both, raising your bleeding risk or salicylate toxicity.

Your pharmacist can look up your exact doses and help you decide.
