HelloPharmacist Scorecard of Essence of Wild Rosemary 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 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

This liquid supplement contains 3 ingredients: a proprietary blend, spring water, and wild oregano oil and rosemary essence. The oregano oil and rosemary are the active components — oregano has been traditionally used for respiratory and digestive support, while rosemary is included for its potential memory-support properties.

There are no other inactive ingredients listed.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

  • Memory via Rosemary Possibly Effective
Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Memory — rated "Possibly Effective" (Rosemary) (Natural Medicines).

Rosemary shows possibly effective evidence for memory support, though more research would strengthen this claim. For oregano, the research on acne, bronchitis, asthma, headache, and upper respiratory infections is insufficient — we don't have enough reliable evidence to say whether it works for these uses.

If you're considering this product for a specific health goal, it's worth asking what the evidence actually shows for that particular purpose.

The evidence, ingredient by ingredient Oregano Rosemary

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.

Wild oregano oil is well tolerated at food amounts, but concentrated supplements are stronger and less studied than their culinary cousins. The most common side effect when taken orally is gastrointestinal upset.

Allergic reactions — including serious ones like anaphylaxis — are rare but have been reported in sensitive people. Topically, oregano can cause skin irritation or dermatitis.

Rosemary is similarly safe in normal food amounts; concentrated extracts require caution. Topically, it can trigger allergic reactions, skin inflammation, or — rarely — photosensitivity.

The undiluted oil is concerning enough that seizures have been reported with it or its camphor component, though this is uncommon.

Moderate identified

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

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Rosemary, Oregano.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 372 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 your medications against these types: blood thinners (anticoagulants and antiplatelet drugs), diabetes medications, aspirin and salicylate-containing pain relievers (including Trilisate and Disalcid), and any drugs your liver metabolizes as CYP1A2 substrates. Use the search tool on this page to run your exact medications.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

If you take blood thinners, diabetes medications, or aspirin-like drugs, check with your pharmacist before using this product — both main ingredients interact with these types of medications. Otherwise, it's generally well tolerated at typical doses.

Avoid medicinal amounts during pregnancy or while breastfeeding and stick to food-level use if you're in either of those situations.

Essence of Wild Rosemary by Physician's Strength: Common Questions

Does Essence of Wild Rosemary by Physician's Strength interact with any medications?
Yes. Based on its ingredients, Essence of Wild Rosemary has a known interaction with 372 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Essence of Wild Rosemary contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 product safe during pregnancy?
Food amounts of oregano and rosemary are likely fine during pregnancy, but medicinal or supplement doses should be avoided. If you're pregnant or planning to be, talk with your doctor or pharmacist before taking this product.
Is it safe while breastfeeding?
Food amounts are likely fine, but safety data on medicinal doses while nursing isn't established. Talk with your pharmacist to decide what's right for you and your baby.
What's the most common side effect?
Gastrointestinal upset — mainly from the oregano oil — is the most common side effect when taken by mouth. Most people tolerate it well at typical doses.
Can this really help with memory?
Rosemary shows possibly effective evidence for memory support, meaning there's some promising research, though more work is needed. Oregano doesn't have strong evidence for the respiratory or other uses listed on many bottles.
Why does this interact with so many medications?
These plant extracts are concentrated — much more potent than a pinch of dried herb in your cooking. Oregano and rosemary can affect how your blood clots and how your body handles blood sugar, which matters when you're already on medications doing the same job.
