HelloPharmacist Scorecard of Oregano Leaf Mint 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 27, 2026

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: oregano leaf glycerite liquid extract — a concentrated preparation of oregano leaf in a glycerin base. The inactive ingredients are glycerin (the liquid base) and mint flavoring.

As a glycerite, it's alcohol-free and designed for direct use or mixing into beverages.

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 Oregano product and its label doesn't state a use — see Oregano'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 we hold doesn't establish that oregano works for the conditions listed on the label — acne, bronchitis, asthma, headache, and upper respiratory tract infection all carry a rating of insufficient reliable evidence. That means the data available isn't enough to say whether it helps or not.

If you're thinking about using it for one of these concerns, talk it over with your doctor or pharmacist about what the science actually supports.

The evidence, ingredient by ingredient Oregano

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.

Oregano is well tolerated in food amounts. This is a concentrated supplement, though, and safety data for larger medicinal doses is limited.

The most common side effect reported is gastrointestinal upset. Rarely, people sensitive to oregano or related plants (like thyme) have had serious allergic reactions, including anaphylaxis — so if you've had reactions to herbs in the mint family, be cautious.

The safety data advises against medicinal or supplement amounts during pregnancy; food amounts are likely fine. For breastfeeding, there isn't enough data to know whether supplement amounts are safe — stick to food amounts and talk with your doctor or pharmacist before adding this as a supplement.

Side effects, ingredient by ingredient Oregano

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Oregano.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 208 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.

If you take blood thinners or antiplatelet drugs (such as warfarin, aspirin, or clopidogrel), check before adding this product — oregano may raise bleeding risk. Also double-check any diabetes medications you take, since oregano might lower blood sugar.

The bottom line

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

This oregano extract may interact with blood thinners, antiplatelet drugs, and diabetes medications, so check your list with your doctor or pharmacist before starting. The evidence for its effectiveness on common respiratory or skin complaints isn't established in our data.

It's well tolerated in food amounts, but as a concentrated supplement, safety data are limited — especially if you have a history of allergies to mint-family plants.

Yes. Based on its ingredients, Oregano Leaf Mint Flavor has a known interaction with 208 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Oregano Leaf Mint 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.
Is this safe to take if I'm pregnant?
The safety data advises against medicinal or supplement amounts of oregano during pregnancy. Food amounts are likely fine, but since this is a concentrated extract, talk with your doctor or pharmacist before using it.
What's the most common side effect?
Gastrointestinal upset — nausea, stomach discomfort, or related digestive symptoms — is the most common side effect reported with oregano in supplement amounts. In rare cases, people sensitive to oregano or related herbs have had serious allergic reactions.
Does oregano actually work for bronchitis or upper respiratory infections?
The evidence we hold doesn't establish that oregano works for those conditions — the rating is insufficient reliable evidence. Talk with your doctor about treatments with stronger data if that's what you're treating.
Is this product alcohol-free?
Yes. It's a glycerite, meaning the oregano extract is suspended in glycerin rather than alcohol.
Can I use this if I'm allergic to thyme or other herbs in the mint family?
Oregano is in the same plant family as thyme. People allergic to one have had allergic reactions to the other, so be cautious or avoid it. Talk with your doctor or pharmacist first.
