HelloPharmacist Scorecard of Wintergreen by Herbal Terra

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 leaf extract in a liquid form. The extract is mixed with alcohol, water, and glycerin as inactive ingredients.

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 it for back pain, muscle soreness, or joint pain.

You're choosing this product largely on its traditional use, not on proven results.

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 well tolerated. However, wintergreen oil is unsafe if swallowed—methyl salicylate in it can cause salicylate poisoning, with symptoms like headache, ringing in the ears, and confusion.

If applied to skin, wintergreen oil is generally well tolerated, but never cover it with an occlusive (airtight) dressing because that can lead to absorption of toxic amounts. The oil can also cause contact dermatitis in some people.

For pregnancy, safety data isn't on file. For breastfeeding, the data rates wintergreen as likely unsafe—so skip it if you're nursing.

  • 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.

Double-check this product if you take warfarin or any other blood thinner—there's a Major risk of increased bleeding. Also check if you take aspirin or other salicylate-containing pain relievers, where the risk is Moderate.

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.

Wintergreen by Herbal Terra: Common Questions

Does Wintergreen by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Wintergreen 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 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 use this if I take warfarin?
No—don't use this without your doctor's or pharmacist's okay. Wintergreen can boost warfarin's effects and raise your bleeding risk. Case reports show it's a serious interaction, so it has to be checked before you start.
What happens if I swallow wintergreen oil?
Wintergreen oil is extremely toxic if swallowed. It contains methyl salicylate, which can cause salicylate poisoning—headaches, ringing in the ears, and confusion. Seek help right away if you or someone else swallows it.
Is this safe to use while breastfeeding?
No. The data rates wintergreen as likely unsafe during breastfeeding, so you should avoid it if you're nursing.
Does wintergreen work for joint or muscle pain?
We don't have reliable evidence that it does. The data shows insufficient evidence to rate it for back pain, muscle soreness, or joint pain.
Can I put it under a bandage or wrap?
No. Never cover wintergreen with an occlusive (airtight) dressing. Doing so can trap the oil and lead to toxic absorption of methyl salicylate through your skin.
