HelloPharmacist Scorecard of Oregano Leaf Liquid Drops by BareOrganics

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

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.
  • “Oregano Leaf Extract” is listed as a grouped ingredient — the label gives one combined amount (1 mL) without saying how much of each component you get.

This product contains one active ingredient: oregano leaf extract. Oregano is an herb from the mint family, traditionally used in cooking and herbal medicine.

The extract is suspended in glycerin and deionized water as inactive ingredients.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: overall immunity support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence we hold doesn't establish that oregano leaf extract works for acne, bronchitis, asthma, headache, or upper respiratory tract infection. For all of these uses, the data shows insufficient reliable evidence to rate it.

If you're considering this product for a specific health goal, talk it over with your doctor or pharmacist about what the current research actually supports.

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 generally well tolerated. When used as a concentrated supplement in larger amounts, it's less studied and warrants more caution.

The most common side effect from oral use is gastrointestinal upset. Rarely, allergic reactions — including serious ones like anaphylaxis — have been reported, especially in people sensitive to the mint family of plants.

Topical oregano oil can cause skin irritation or allergic dermatitis in sensitive individuals. During pregnancy, medicinal or supplement amounts of oregano are not advised, though food amounts are likely fine.

While breastfeeding, safety data for oregano supplements isn't established — stick to normal food amounts. If you're pregnant or nursing and want to use this product, talk with your doctor or pharmacist first.

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 start this product, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like warfarin or aspirin) — oregano may increase bleeding risk. Also flag it if you take diabetes medications, since oregano might lower blood sugar further and raise the risk of low blood sugar episodes.

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.

This product is oregano leaf extract in a liquid form. It's generally well tolerated in food amounts, but as a concentrated supplement it interacts with blood thinners and diabetes medications — both moderately serious — and the evidence for its effectiveness for common uses like bronchitis or asthma isn't established yet.

If you take blood thinners, diabetes drugs, or have a known allergy to plants in the mint family, check with your doctor or pharmacist before starting. Anyone pregnant or breastfeeding should also confirm with their healthcare provider first.

Oregano Leaf Liquid Drops by BareOrganics: Common Questions

Does Oregano Leaf Liquid Drops by BareOrganics interact with any medications?
Yes. Based on its ingredients, Oregano Leaf Liquid Drops 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?
Oregano Leaf Liquid Drops 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 if I'm pregnant?
Oregano in normal food amounts is likely fine during pregnancy, but medicinal or supplement amounts — like this concentrated extract — are not advised. Talk with your doctor or pharmacist about whether this product is right for you.
Can oregano help with bronchitis or respiratory infections?
The evidence we hold doesn't establish that oregano works for bronchitis, asthma, or upper respiratory tract infections. For these uses, we have insufficient reliable evidence to rate it. Your doctor can discuss other options that have stronger support.
What are the common side effects?
When taken by mouth in food amounts, oregano is generally well tolerated. The most common side effect from larger medicinal doses is gastrointestinal upset. Allergic reactions are rare but have been reported, especially in people sensitive to the mint family of plants.
Is this product actually a 'liquid drop' of pure oregano?
This is an oregano leaf extract suspended in glycerin and deionized water. It's more concentrated than culinary oregano, which is why caution applies when using supplement amounts — the extract is stronger and less studied than the herb you'd use in cooking.
Can I use this if I'm allergic to mint or basil?
Oregano is in the same plant family as mint and basil (Lamiaceae). If you have a known allergy to plants in that family, you should not use this product — systemic allergic reactions have been reported. Talk with your doctor or pharmacist before trying it.
