HelloPharmacist Scorecard of Oil of Oregano by Absonutrix

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 Jul 11, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “Wild Oregano Oil Extract” is listed as a grouped ingredient — the label gives one combined amount (43 mg) without saying how much of each component you get.

This liquid contains 2 active ingredients: Extra Virgin Olive Oil and a blend of Wild Oregano Oil Extract and Mediterranean Oregano. There are no other inactive ingredients listed.

The oregano components are the ones with documented medicinal activity in the research; the olive oil serves as a carrier and base for the product.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Natural immune booster and antiseptic support.
  • We looked for evidence on: Bronchitis, Cough, Exercise-induced respiratory infections, Influenza, Intestinal parasite infection, Rhinosinusitis — and 4 related terms.
  • The closest evidence on file: Olive is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced respiratory infections (Natural Medicines).
  • Also on file: Olive is rated "Insufficient Reliable Evidence To Rate" for Influenza.
  • Also on file: Oregano is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Upper respiratory tract infection (URTI), Cough, Intestinal parasite infection, and more.

The evidence for how well this product works is not established in our data. Extra Virgin Olive Oil is rated insufficient evidence for osteoporosis, upset stomach, shingles, flu, and exercise-related respiratory infections.

Mediterranean Oregano is also rated insufficient evidence for acne, bronchitis, asthma, headache, and upper respiratory infections. Neither ingredient has a rating showing it works reliably for any condition, so we can't claim benefit for specific uses based on the data we hold.

The evidence, ingredient by ingredient Oregano Olive

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

When oregano is used in normal food amounts, it's well tolerated — the main side effects at that level are occasional stomach upset. Concentrated oregano supplements are stronger and less studied than food amounts.

Allergic reactions are rare but can happen; one reported case involved a man who developed swelling, trouble breathing, and a drop in blood pressure after eating oregano-seasoned pizza. Topical oregano oil at concentrations above 1% may irritate skin or mucous membranes.

Extra Virgin Olive Oil in food form is very safe, but the safety of concentrated olive supplements is not well known — talk with your doctor before using a concentrated supplement. For pregnancy: medicinal or supplement amounts of oregano should be avoided during pregnancy, though normal food amounts are likely fine.

For breastfeeding: stick to normal food amounts; the safety of oregano supplements while nursing is not established. Data on olive oil's safety during pregnancy and lactation is not on file.

Side effects, ingredient by ingredient Oregano Olive

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 2 matched ingredients 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.

Before you start, double-check this product if you take blood thinners or antiplatelet drugs — oregano may increase bleeding risk (Moderate interaction). Also verify your diabetes medications; oregano may lower blood sugar and boost the effect of your drug (Moderate interaction).

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you take blood thinners, diabetes medications, or have a known allergy to oregano or thyme, check with your pharmacist before starting. Oregano is a common food seasoning and generally well tolerated, but this is a concentrated supplement — stronger and less studied than the herb you'd use in cooking.

Your doctor or pharmacist can help you weigh whether it's right for you.

Oil of Oregano by Absonutrix: Common Questions

Does Oil of Oregano by Absonutrix interact with any medications?
Yes. Based on its ingredients, Oil of Oregano 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?
Oil of Oregano 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 safe during pregnancy?
The safety data advises against medicinal or supplement amounts of oregano during pregnancy. Normal food amounts are likely fine, but for personalized guidance, talk with your doctor or pharmacist about whether this product is right for you.
What's the most common side effect?
Stomach upset is the most common side effect when oregano is used orally. At normal food amounts, oregano is well tolerated; concentrated supplements have less safety data behind them.
Can oregano cause allergic reactions?
Yes, though allergic reactions are rare. Serious ones, including anaphylaxis and swelling of the throat and lips, have been reported in sensitive people. If you have a known allergy to oregano, thyme, or other plants in the mint family, avoid this product.
Does this product actually work for [condition]?
We don't have reliable evidence showing oregano or olive oil work for any specific condition — the data rates both ingredients as insufficient evidence for the conditions they're promoted for. Check with your pharmacist if you want to discuss whether it might help with your particular health concern.
Why does the bottle say it's a blend if there are only two ingredients?
The oregano component is listed as a blend of Wild Oregano Oil Extract and Mediterranean Oregano — that's how the product is formulated. Extra Virgin Olive Oil is the second active ingredient and serves as the carrier base.
