HelloPharmacist Scorecard of Wintergreen Herb Vanilla Flavor by TerraVita

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 one active ingredient: wintergreen herb glycerite liquid extract. Wintergreen oil is the key compound, and it carries methyl salicylate — the same chemical found in aspirin.

The formula also includes glycerin and vanilla flavor 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 the data we hold. We have insufficient reliable evidence to rate it for back pain, muscle soreness, or joint pain.

If you're considering this product for one of those reasons, talk with your pharmacist about what the research actually supports.

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.

Orally, wintergreen leaf seems well tolerated, but wintergreen oil may be unsafe when swallowed — the essential oil is extremely toxic if ingested and can cause salicylate poisoning (headache, ringing in the ears, confusion). Topically, wintergreen oil is generally well tolerated, but don't cover the area with a bandage or wrap, as that can trap the oil and lead to dangerous absorption of methyl salicylate.

Pregnancy and lactation data: We don't have enough safety information for pregnancy. For lactation, wintergreen oil is rated likely unsafe — talk with your doctor or pharmacist before using it if you're breastfeeding.

Side effects, ingredient by ingredient Wintergreen

Meds to double-check

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.

Before you start, double-check if you take warfarin (a blood thinner) or aspirin. Wintergreen oil can increase the effect of warfarin and raise your bleeding risk, and it can add to aspirin's salicylate load.

Either way, a quick conversation with your pharmacist is worth it.

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 herb extract isn't for everyone. If you take warfarin or aspirin, check with your pharmacist first — the interaction is real and could affect your safety.

The evidence for joint or muscle pain isn't solid either. A pharmacist can help you weigh the risks against what you're hoping it'll do.

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 Herb Vanilla Flavor by TerraVita: Common Questions

Does Wintergreen Herb Vanilla Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Wintergreen Herb Vanilla Flavor 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 Vanilla Flavor 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 take this if I'm on warfarin?
Not without talking to your pharmacist first. Wintergreen oil can increase warfarin's effects and your bleeding risk — case reports show it can raise your INR. Your pharmacist needs to review this with you.
Is wintergreen oil safe to swallow?
No. The essential oil is extremely toxic if swallowed and can cause salicylate poisoning with symptoms like headache, ringing in the ears, and confusion. This product is a liquid extract, so you need to be clear on the directions and dosing.
Can I use this while breastfeeding?
Wintergreen oil is rated likely unsafe during lactation. Talk with your doctor or pharmacist before using it if you're nursing.
Does wintergreen actually work for joint pain?
We don't have enough reliable evidence to say. The data we hold rates it as insufficient evidence for joint pain, muscle soreness, and back pain.
What happens if I cover the area where I apply it with a bandage?
Don't do that. If you apply wintergreen topically and cover it with an occlusive dressing (a bandage or wrap), it can trap the oil and lead to dangerous absorption of methyl salicylate, the active compound.
