HelloPharmacist Scorecard of OregaWild by Physician's Strength

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

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 1 of its 2 active ingredients.

OregaWild contains 2 active ingredients: wild Mediterranean oregano oil and a proprietary blend. We don't have details on what the proprietary blend contains, so we cannot fully describe all the actives in this product.

Oregano oil is a concentrated extract — much stronger than the oregano you'd use in cooking. There are no inactive ingredients listed for this product.

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 product facts we have don't establish how well oregano works for any condition. For acne, bronchitis, asthma, headache, and upper respiratory tract infection (URTI), the evidence is rated insufficient — meaning there isn't enough reliable research to say whether it helps or doesn't.

We also have no effectiveness information for the proprietary blend. If you're considering this for a specific health concern, talk it over with your doctor or pharmacist.

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, but this is a concentrated supplement — much stronger and less studied than what you'd get from seasoning. The most common side effect when taken orally is stomach upset.

Rarely, people can have allergic reactions ranging from itching and rash to serious reactions like anaphylaxis, especially if you're sensitive to plants in the mint family (Lamiaceae). Topically, oregano oil at concentrations above 1% can irritate mucous membranes and cause contact dermatitis in sensitive skin.

Avoid medicinal or supplement amounts during pregnancy; food amounts are likely fine. While breastfeeding, safety data isn't established — stick to normal food amounts and talk with your doctor or pharmacist about whether supplementing is right for you.

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.

Before you take Physician's Strength OregaWild, double-check with your doctor or pharmacist if you're on blood thinners (anticoagulants or antiplatelet drugs) — oregano may increase bleeding risk — or diabetes medication, where it may raise the risk of low blood sugar (hypoglycemia). We could not check the proprietary blend ingredient for interactions.

Check your own medication Run your meds through the checker above

The bottom line

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

OregaWild may be worth considering if you're looking for an oregano supplement, but the evidence for what it actually does is sparse. The bigger question is whether it's safe for you: if you take blood thinners or diabetes medication, you need to check with your doctor or pharmacist first.

And if you have a history of allergies to plants like oregano or thyme, be cautious — serious reactions are rare but have been reported.
