HelloPharmacist Scorecard of Wild Oregano-Plus 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 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.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (550 mg) without saying how much of each component you get.

This product has 2 active ingredients. The main one is wild oregano, a concentrated form of the herb you'd normally use in cooking.

The other ingredient is wild sumac. Both are in a proprietary blend, which means the exact amounts of each aren't listed on the label — you're getting a combined dose.

The capsule also contains cellulose, an inactive ingredient used as a filler.

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 — see Oregano's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: supporting healthy immune system and digestion.
  • We looked for evidence on: Bronchitis, Cough, Dyspepsia, Intestinal parasite infection, Upper respiratory tract infection (URTI), Gut health — and 3 related terms.
  • The closest evidence on file: Oregano is rated "Insufficient Reliable Evidence To Rate" for Bronchitis (Natural Medicines).
  • Also on file: Oregano is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI), Cough, Dyspepsia, Intestinal parasite infection.

The evidence for wild oregano isn't established yet in our data. The facts list several uses — acne, bronchitis, asthma, headache, and upper respiratory infections — but all of them are rated as having insufficient reliable evidence.

That doesn't mean oregano doesn't work; it means the studies aren't solid enough to confirm it either way. We hold no effectiveness information for wild sumac.

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 from food is well tolerated. Concentrated supplements like this one are much stronger and less studied, so the safety picture is less clear.

Gastrointestinal upset is the most common side effect when taken by mouth. Rarely, people have had allergic reactions including anaphylaxis, and oregano oil at high concentrations can irritate mucous membranes or cause contact dermatitis in sensitive people.

During pregnancy, stick to oregano in normal food amounts — medicinal amounts should be avoided. While breastfeeding, the safety of oregano supplements isn't established, so talk to your pharmacist before using it.

We don't have safety data for wild sumac in pregnancy or breastfeeding.

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 your blood thinners or antiplatelet drugs (like warfarin or aspirin) with your pharmacist before taking this — oregano may increase bleeding risk. Also flag any diabetes medications you take, as oregano might lower your blood sugar further.

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 or diabetes medications, check with your pharmacist before starting this product. If you have a known allergy to oregano or other herbs in the mint family (Lamiaceae), skip it.

Otherwise, it's generally well tolerated in food-like amounts, though concentrated supplements carry more unknowns.
