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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Brown Bee Propolis by NaturaNectar contains 2 active ingredients: Brazilian brown propolis and Brazilian brown propolis water extract. Propolis is a resin-like substance that honeybees collect and use to seal their hives.

The product also includes inactive ingredients (cellulose, magnesium stearate, and silicon dioxide) as binders and capsule material.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Immune support and wellness protection.
  • We looked for evidence on: Common cold, Upper respiratory tract infection (URTI), Herpes labialis (cold sores), Genital herpes, Oral mucositis, Canker sores — and 4 related terms.
  • The strongest evidence on file: Propolis is rated "Possibly Effective" for Herpes labialis (cold sores) (Natural Medicines).
  • Also on file: Propolis is rated "Possibly Effective" for Oral mucositis.
  • Also on file: Propolis is rated "Insufficient Reliable Evidence To Rate" for Common cold, Gingivitis, Upper respiratory tract infection (URTI), Periodontitis, and more.

The propolis in this product is possibly effective for oral mucositis (mouth inflammation or sores) and herpes labialis (cold sores), based on clinical evidence. It's also possibly effective for diabetes support.

For dengue fever, there isn't enough reliable evidence yet to know whether it helps.

The evidence, ingredient by ingredient Propolis

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.

Propolis is generally well tolerated over the short term. The most common side effect is mild headache—in one trial, about 7% of people taking 250 mg twice daily for 4 months reported this.

People sensitive to bee products can develop allergic reactions, which are rare but possible. Because there isn't enough safety information, this product should be avoided during pregnancy and while breastfeeding.

Side effects, ingredient by ingredient Propolis

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 — Propolis.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 922 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 taking this, double-check with your pharmacist if you're on blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel, and others), as propolis may increase bleeding risk or reduce warfarin's effectiveness. Also ask about any medications your liver processes, since propolis may theoretically raise their blood levels at high doses.

The medication checker on this page can help you screen your prescriptions.

Brazilian Brown Propolis8 drug types · 921 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, propolis might increase the risk of bleeding when taken with antiplatelet or anticoagulant drugs.
In vitro research shows that propolis water extract and the propolis constituent, caffeic acid phenethyl ester, can inhibit platelet aggregation. Additionally, evidence from an animal model shows that taking propolis in addition to warfarin decreases INR, suggesting that propolis can decrease the effectiveness of warfarin.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, high doses of propolis might increase blood levels of drugs metabolized by CYP1A2.
In vitro research shows that propolis extract can inhibit CYP1A2. However, animal research shows that propolis extract does not significantly affect CYP1A2 activity when administered to rats at doses up to 250 mg/kg. It is postulated that the constituents of propolis that inhibit CYP1A2 in vitro do not have significant effects in vivo due to low bioavailability and hepatic first-pass effect. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, high doses of propolis might increase blood levels of drugs metabolized by CYP2C19.
In vitro research shows that propolis extract can inhibit CYP2C19. However, animal research shows that propolis extract does not significantly affect CYP2C19 activity when administered to rats at doses up to 250 mg/kg. It is postulated that the constituents of propolis that inhibit CYP2C19 in vitro do not have significant effects in vivo due to low bioavailability and hepatic first-pass effect. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, high doses of propolis might increase blood levels of drugs metabolized by CYP2C9.
In vitro research shows that propolis extract can inhibit CYP2C9. However, animal research shows that propolis extract does not significantly affect CYP2C9 activity when administered to rats at doses up to 250 mg/kg. It is postulated that the constituents of propolis that inhibit CYP2C9 in vitro do not have significant effects in vivo due to low bioavailability and hepatic first-pass effect. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, high doses of propolis might increase blood levels of drugs metabolized by CYP2D6.
In vitro research shows that propolis extract can inhibit CYP2D6. However, animal research shows that propolis extract does not significantly affect CYP2D6 activity when administered to rats at doses up to 250 mg/kg. It is postulated that the constituents of propolis that inhibit CYP2D6 in vitro do not have significant effects in vivo due to low bioavailability and hepatic first-pass effect. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, propolis might increase levels of drugs metabolized by CYP2E1.
In vitro research shows that propolis can inhibit CYP2E1. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, high doses of propolis might increase blood levels of drugs metabolized by CYP3A4.
Some in vitro research shows that propolis extract can inhibit CYP3A4; however, other in vitro research shows that propolis has no effect on CYP3A4 activity. Furthermore, animal research shows that propolis extract does not significantly affect CYP3A4 activity when administered to rats at doses up to 250 mg/kg. It is postulated that the constituents of propolis that might in inhibit CYP3A4 in vitro do not have significant effects in vivo due to low bioavailability and hepatic first-pass effect. This effect has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, propolis might decrease the effectiveness of warfarin.
Animal research shows that taking propolis in addition to warfarin decreases the international normalized ratio (INR). This effect has not been reported in humans.

How can one product interact with so many drugs?
Brown Bee Propolis contains 2 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.
Can I take this if I'm pregnant or breastfeeding?
During pregnancy, there isn't enough safety information, so it's best to avoid this product. While breastfeeding, the data suggests it's possibly safe, but you should talk with your doctor or pharmacist for personalized advice before starting.
What's the difference between the two propolis ingredients in this product?
One is Brazilian brown propolis in its raw form, and the other is a water extract of the same propolis. Both have the same interactions and effectiveness ratings—the water extract is simply a processed version that may be easier for your body to absorb.

Propolis is possibly effective for herpes labialis (cold sores) based on available evidence, which means there's some clinical support but it's not proven beyond doubt. Your results may vary.
What side effects should I watch for?
Most people tolerate propolis well. The most common side effect is mild headache. If you're sensitive to bee products, you could have an allergic reaction—stop and call your doctor if you notice itching, swelling, or trouble breathing.
