HelloPharmacist Scorecard of Wintergreen Herb Powder by TerraVita Premium Collection

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
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: wintergreen herb in powder form. Wintergreen is an herb traditionally used for back pain, muscle soreness, and joint pain, though the scientific evidence for these uses is not well established.

There are no inactive ingredients listed.

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's effectiveness is insufficient for all three conditions listed — back pain, muscle soreness, and joint pain. We don't have reliable data showing it works for any of them, so we can't recommend it based on proven benefit.

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 appears to be generally well tolerated, but wintergreen oil is unsafe to swallow — it can cause salicylate poisoning with symptoms like headache, ringing in the ears, and confusion. The safety data is not strong enough to support use in pregnancy or breastfeeding; lactation is rated as likely unsafe.

Topically, wintergreen oil is generally well tolerated, but it can cause contact dermatitis (skin irritation or allergic reaction), and you should never cover it with an occlusive dressing because that can trap methyl salicylate and cause toxic absorption.

  • 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 with your pharmacist if you take warfarin (Coumadin) or aspirin before starting this product. These are the medication types we have documented interactions for.

Altogether, these interactions span 37 individual medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

If you take warfarin or aspirin, talk to your pharmacist or doctor before using this product — the interaction risk is real and documented. Because the effectiveness evidence is weak and safety questions remain, especially for oral use, you'll want to discuss whether this is the right choice for you.

Wintergreen Herb, Powder2 drug types · 37 drugs

Warfarin (Coumadin)

Using wintergreen oil topically might increase the effects and adverse effects of warfarin.
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 contains methyl salicylate. Topical analgesic gels, lotions, creams, ointments, liniments, and sprays can contain up to 55% methyl salicylate.

Wintergreen Herb Powder by TerraVita Premium Collection: Common Questions

Does Wintergreen Herb Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Wintergreen Herb Powder 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 Herb Powder 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.
Is wintergreen oil safe to swallow?
No. Wintergreen oil is extremely toxic if swallowed and can cause salicylate poisoning — symptoms include headache, ringing in the ears, and confusion. This product is a powder, so you need to be very clear about how you're using it and never ingest wintergreen oil directly.
Can I use this if I'm pregnant or breastfeeding?
The safety data isn't there for pregnancy, and breastfeeding is rated as likely unsafe. Talk with your doctor or pharmacist before using this while pregnant or nursing — they can give you personalized advice based on your situation.
Does wintergreen work for back pain or sore muscles?
The evidence isn't strong enough to say. We don't have reliable data showing it's effective for back pain, muscle soreness, or joint pain, so we can't confirm it'll help.
What happens if I use wintergreen topically under a bandage?
Don't do that. Covering wintergreen oil with an occlusive dressing traps the methyl salicylate and lets toxic amounts get absorbed through your skin. Use it only on clean, uncovered skin.
Can wintergreen cause a skin reaction?
Yes. Wintergreen oil can cause contact dermatitis — either irritant or allergic skin reactions — though these are generally mild when applied topically without occlusion.
