HelloPharmacist Scorecard of Bee Propolis Tincture 25% Extract by Natural Factors

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 12, 2026

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

This product contains one active ingredient: bee propolis, presented as a 25% extract in a liquid form. Propolis is a resinous mixture that honeybees collect from plants and use to seal their hives.

The tincture also contains ethanol as an inactive ingredient (the liquid carrier).

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 Propolis's overall clinical evidence instead.

Moderate

Some clinical evidence supports Propolis for:

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 ingredient's overall clinical evidence instead.
  • On file: Diabetes — rated "Possibly Effective" (Natural Medicines).
  • On file: Herpes labialis (cold sores) — rated "Possibly Effective" (Natural Medicines).
  • On file: Oral mucositis — rated "Possibly Effective" (Natural Medicines).

Propolis is possibly effective for oral mucositis (mouth sores, often from cancer treatment) and herpes labialis (cold sores). It's also possibly effective for diabetes.

For dengue fever, the evidence isn't established enough in the data we hold to rate it. If you're considering this for one of those conditions, talk to your healthcare provider about what the research actually shows for your situation.

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 when taken orally or applied to skin short-term. The most common side effect is mild headache — in one clinical trial, about 7% of people taking 250 mg twice daily for 4 months reported it.

Topically, it can cause contact dermatitis or cheilitis (inflamed lips) in sensitive people. Allergic reactions are possible, especially if you're sensitive to bee products.

Severe allergic reactions are rare but can happen. Propolis is not recommended during pregnancy or breastfeeding — there isn't enough safety information to know either way, so talk with your doctor or pharmacist for personalized advice if you're pregnant, nursing, or planning to be.

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 you take this product, double-check if you're on blood thinners (anticoagulants) like warfarin, or antiplatelet drugs — propolis may raise bleeding risk. Also flag any medications metabolized by your liver's CYP enzymes (CYP2C19, CYP2D6, CYP1A2, CYP2C9, CYP3A4, CYP2E1), including many heart, blood pressure, depression, and pain medications.

Use the search tool on this page with your exact drug names to be sure.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Bee propolis may help with cold sores, mouth sores from cancer treatment, or blood sugar — but you'll want to check it against your medications first, particularly if you take blood thinners or drugs metabolized by your liver. If you're allergic to bees or bee products, skip it.

Talk to your pharmacist before adding it to your routine.

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.

Bee Propolis Tincture 25% Extract by Natural Factors: Common Questions

Does Bee Propolis Tincture 25% Extract by Natural Factors interact with any medications?
Yes. Based on its ingredients, Bee Propolis Tincture 25% Extract has a known interaction with 921 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bee Propolis Tincture 25% Extract 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 bee propolis safe if I'm allergic to bees?
No. People allergic to bees or bee products are more likely to have allergic reactions to propolis, including severe ones in rare cases. If you have a bee allergy, avoid this product.
What's the most common side effect?
Mild headache. In a clinical trial, about 7% of people taking propolis 250 mg twice daily for 4 months reported it. If you apply it to your skin, you might get contact dermatitis or inflamed lips instead.
Can I take this while pregnant or breastfeeding?
There isn't enough safety data to know. You should avoid it during pregnancy. While breastfeeding, it's possibly safe, but talk with your doctor or pharmacist before using it to make sure it's right for you.
Does propolis actually work for cold sores?
The evidence says it's possibly effective for herpes labialis (cold sores). It's also possibly effective for oral mucositis and diabetes. Those ratings mean research is promising but not yet rock-solid — ask your provider if it's worth trying for your situation.
Why do I need to check this with my medications?
Propolis can slow how your liver breaks down many drugs, potentially raising their levels in your blood. It may also increase bleeding risk if you're on blood thinners. That's why your exact medication list matters — use the tool on this page to check.
