HelloPharmacist Scorecard of Immune Bee Propolis Extract Drops PFL 30 by Comvita

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

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: propolis extract, a resinous mixture that honeybees collect and use to seal their hives. The liquid also includes propylene glycol as an inactive ingredient to carry the propolis.

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 health and oral health support.
  • We looked for evidence on: Common cold, Upper respiratory tract infection (URTI), Herpes labialis (cold sores), Canker sores, Gingivitis, Periodontitis — 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.

Propolis extract is possibly effective for oral mucositis (mouth sores from cancer treatment) and herpes labialis (cold sores). For diabetes, the evidence rates it possibly effective as well.

For dengue fever, there isn't enough reliable evidence to say whether it works. The data we hold doesn't establish effectiveness for other uses.

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 by mouth or applied to skin short-term. Headache is the most common side effect — about 7% of people in one trial reported mild headache when taking 250 mg twice daily for 4 months.

Allergic reactions are possible, especially in people sensitive to bee products; in rare cases, oral propolis can trigger severe allergic reactions. Topically, it may cause contact dermatitis, rash-like reactions, or cheilitis (inflammation of the lips) in sensitive individuals.

There isn't enough safety data to know whether propolis is safe during pregnancy or breastfeeding — the safety data advises against use in both situations.

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.

Check your blood thinners and antiplatelet drugs (like warfarin, aspirin, or clopidogrel) before starting — propolis may increase bleeding risk and reduce warfarin's effectiveness. Also double-check any drugs your liver breaks down, including heart medications, antidepressants, and certain cancer drugs — propolis could raise their blood levels, though the real-world risk at typical doses is uncertain.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Propolis extract may help with cold sores and mouth sores from cancer treatment, and possibly with blood sugar. But it interacts with blood thinners and can theoretically affect how your liver processes many common medications.

If you're on any prescription, especially blood thinners, heart drugs, or antidepressants, check with us before starting. Anyone allergic to bee products should skip it.

High strength immune support

Made in New Zealand from imported and New Zealand ingredients.

Honey bees are clever. They make propolis by collecting resin from trees and combine it with beeswax and enzymes to seal and protect the hive. Bee Propolis originates from a plant's defense system and contains over 300 powerful natural bioactive compounds, flavonoids and phenolics (antioxidants) which can support immune function. Comvita is dedicated to bringing you the finest scientifically-backed pure and natural bee products that nature has to offer. PFL stands for Propolis Flavonoid Level. This measures the flavonoid content in a serve of propolis.

Propolis extract8 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.

Immune Bee Propolis Extract Drops PFL 30 by Comvita: Common Questions

Does Immune Bee Propolis Extract Drops PFL 30 by Comvita interact with any medications?
Yes. Based on its ingredients, Immune Bee Propolis Extract Drops PFL 30 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?
Immune Bee Propolis Extract Drops PFL 30 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.
Can I take this if I'm allergic to bees?
No. Propolis comes directly from bees, and people allergic to bee products are more likely to have allergic reactions to it — sometimes severe. Skip it and talk with your pharmacist about alternatives.
Will I get a headache from this?
Headache is the most common side effect, but it's mild and not everyone gets it. In one trial, about 7% of people taking 250 mg twice daily for 4 months reported mild headache.
Is propolis safe during pregnancy or breastfeeding?
There isn't enough safety data to know either way. The safety information advises against use during pregnancy and while breastfeeding — talk with your doctor or pharmacist for personalized advice.
Does propolis actually work for cold sores?
The evidence says it's possibly effective for cold sores and mouth sores from cancer treatment. It's not a proven cure, but there's enough research to suggest it may help.
Can I use this if I'm on a blood thinner?
Propolis may increase bleeding risk with blood thinners and could reduce warfarin's effectiveness. Don't start it without checking with your pharmacist first — this needs a careful look at your specific medication.
