HelloPharmacist Scorecard of Origanox by OL Olympian Labs, Inc.

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.

Origanox contains one active ingredient: Origanox WS natural plant extract, which is an oregano extract. This is a concentrated form of oregano — much stronger than what you'd shake onto a pizza.

The capsule also holds several inactive ingredients that are standard fillers and binders: rice flour, microcrystalline cellulose, silicon dioxide, ascorbyl palmitate, and a vegetarian capsule shell.

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 for oregano extract does not support its use for acne, bronchitis, asthma, headache, or upper respiratory tract infections — the data is simply insufficient to say whether it works for any of these. If you're considering Origanox for one of these reasons, talk it over with your doctor or pharmacist about whether the research supports it or whether something else might be a better choice.

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 in food amounts — the pinch you'd use in cooking — is well tolerated and safe. But Origanox is a concentrated supplement, and the safety data for oregano at that strength is limited.

The most common side effect is stomach upset. Rarely, people have had serious allergic reactions, including trouble breathing and swelling of the lips and tongue.

During pregnancy, the safety data advises against using medicinal or supplement amounts of oregano, though food amounts are likely fine. For breastfeeding, there isn't enough data to know whether supplemental oregano is safe — talk with your doctor or pharmacist before taking it while nursing.

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.

Check with your doctor or pharmacist before taking Origanox if you take blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel) — oregano may raise bleeding risk. Also confirm if you take diabetes medications, since oregano might lower blood sugar further and trigger low blood sugar symptoms.

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.

Origanox is an oregano extract supplement. It's generally well tolerated at food doses, but we don't have solid evidence it works for the conditions it's often marketed for.

More importantly, it may interact with blood thinners and diabetes drugs, so if you take either, check with your doctor or pharmacist before starting. During pregnancy, avoid medicinal doses.

Origanox by OL Olympian Labs, Inc.: Common Questions

Does Origanox by OL Olympian Labs, Inc. interact with any medications?
Yes. Based on its ingredients, Origanox 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?
Origanox 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 oregano supplement the same as oregano on my food?
No. Origanox is a concentrated extract — much stronger than the dried oregano you sprinkle on pizza or pasta. Oregano in food amounts is safe, but concentrated supplements like this one haven't been as thoroughly studied at higher doses.
Can I take this while I'm pregnant?
The safety data advises against taking medicinal or supplement amounts of oregano during pregnancy. Food amounts are likely fine, but if you're pregnant or planning to be, talk with your doctor or pharmacist before taking Origanox.
What's the most common side effect?
Stomach upset is the most common side effect when people take oregano orally. Rarely, sensitive individuals have had serious allergic reactions, including difficulty breathing and swelling.
Can I take this for a cough or bronchitis?
The evidence we hold on oregano for bronchitis, asthma, and other respiratory conditions is insufficient — we can't say from the data whether it actually works. Talk with your doctor about what might help.
Is this safe if I'm breastfeeding?
There isn't enough data on the safety of oregano supplements while breastfeeding. Check with your doctor or pharmacist before taking Origanox if you're nursing.
