HelloPharmacist Scorecard of Wintergreen Oil by Pure Herbs

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.

This product contains one active ingredient: wintergreen oil, which is a liquid extract containing methyl salicylate. There are no inactive ingredients listed.

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 Wintergreen's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: muscle and joint discomfort.
  • We looked for evidence on: Back pain, Joint pain, Muscle soreness, Arthritis, Inflammation.
  • The closest evidence on file: Wintergreen is rated "Insufficient Reliable Evidence To Rate" for Back pain (Natural Medicines).
  • Also on file: Wintergreen is rated "Insufficient Reliable Evidence To Rate" for Muscle soreness, Joint pain.

The evidence we hold doesn't establish that wintergreen oil works for back pain, muscle soreness, or joint pain. All three conditions are rated insufficient reliable evidence to rate, which means the data available isn't strong enough to say whether it helps.

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.

Topical use of wintergreen oil in normal amounts appears generally well tolerated on the skin—though it can occasionally cause contact dermatitis (skin irritation or allergic reaction). The critical safety issue is swallowing it: the essential oil is extremely toxic if taken by mouth and can cause salicylate poisoning with symptoms like headache, ringing in the ears, and confusion.

Never cover wintergreen oil with an occlusive (airtight) dressing, because that increases skin absorption of toxic amounts of methyl salicylate. For pregnancy, the safety data is rated as likely unsafe during lactation (breastfeeding).

We don't have pregnancy data on file. Anyone who is pregnant or breastfeeding should talk with their doctor or pharmacist before using this product.

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 this product against warfarin (Coumadin) or any blood thinner before you use it—Major risk of increased bleeding. Also check aspirin or aspirin-type pain relievers, especially if you're using large amounts topically or for long periods.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

Wintergreen oil may appeal to someone looking for a topical pain approach, but it carries real risks if you take warfarin or aspirin. It's not proven to work for back pain, muscle soreness, or joint pain.

Check your medications before starting, and never swallow it or cover it with an airtight dressing.

Several case reports show that concomitant use of topical wintergreen oil-containing products and warfarin can increase INR and bleeding risk due to systemic absorption of the methyl salicylate contained in wintergreen oil. Topical analgesic gels, lotions, creams, ointments, liniments, and sprays can contain up to 55% methyl salicylate.

Likelihood Probable Evidence D
Aspirin

Using wintergreen oil topically in large amounts, with occlusive dressings, or for prolonged periods of time might increase the risk of additive salicylate toxicity when used with aspirin.

Wintergreen Oil by Pure Herbs: Common Questions

Does Wintergreen Oil by Pure Herbs interact with any medications?
Yes. Based on its ingredients, Wintergreen Oil has a known interaction with 37 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wintergreen Oil 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.
Can I swallow wintergreen oil?
No—the essential oil is extremely toxic if swallowed and can cause salicylate poisoning with headache, ringing in the ears, and confusion. Use it only on your skin as directed.
Can I cover the oil with a bandage or wrap after applying it?
No. Don't use an airtight dressing over wintergreen oil, because that increases how much gets absorbed through your skin and raises the risk of toxic effects.
Is wintergreen oil proven to help back pain or joint pain?
The evidence isn't strong enough yet. All three conditions—back pain, muscle soreness, and joint pain—are rated insufficient reliable evidence to rate, so we can't say whether it works.
What's in this product?
Wintergreen Oil by Pure Herbs is just wintergreen oil in liquid form—no fillers or other inactive ingredients. The active compound is methyl salicylate, which is similar to aspirin.
Is it safe to use while breastfeeding?
The safety data rates it as likely unsafe during lactation. Talk with your doctor or pharmacist before using it if you're breastfeeding.
