HelloPharmacist Scorecard of 50% Super Strength Propolis by Y.S. Eco Bee Farms

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 substance collected by honeybees. The liquid form includes grain alcohol as an inactive ingredient to preserve and deliver 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 support and oral health.
  • We looked for evidence on: Common cold, Upper respiratory tract infection (URTI), Herpes labialis (cold sores), Genital herpes, Gingivitis, Oral mucositis — 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, Dental caries, Gingivitis, Upper respiratory tract infection (URTI), and more.

Propolis has possibly effective evidence for oral mucositis (mouth sores) and herpes labialis (cold sores) when used orally or topically. It's also possibly effective for diabetes.

For dengue fever, the evidence is too thin for us to rate it. If you're considering propolis for any of these uses, talk with your pharmacist about whether the evidence matches 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 short term, though allergic reactions are possible — especially if you're sensitive to bee products. The most common side effect from oral use is mild headache; a small number of trial participants reported this at a dose of 250 mg twice daily over 4 months.

Topically, it can cause contact dermatitis or cheilitis (inflamed lips) in sensitive individuals. Don't use propolis during pregnancy or while breastfeeding; there isn't enough safety data to know either way, and the facts advise against both.

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 you start, double-check your medications against blood thinners and antiplatelet drugs (warfarin and others), which could bleed more easily if combined with propolis. Also verify any drug your liver breaks down — that spans many common medications.

If you're not sure whether a drug is affected, the interaction tool on this page will tell you.

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 may help with cold sores, mouth sores, or blood sugar, but it interacts with a very broad range of medications — nearly everything that passes through your liver. If you take any prescription drugs, check with your pharmacist before adding this.

It's not safe to use in pregnancy or while nursing.

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.

50% Super Strength Propolis by Y.S. Eco Bee Farms: Common Questions

Does 50% Super Strength Propolis by Y.S. Eco Bee Farms interact with any medications?
Yes. Based on its ingredients, 50% Super Strength Propolis 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?
50% Super Strength Propolis 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 bee products?
No. Propolis is made from bee resin, and people allergic to bees or bee products are more likely to have allergic reactions to it. Talk to your pharmacist or doctor first if you have any bee allergies.
What side effects should I watch for?
Most commonly, mild headache. Topically, some people get contact dermatitis or inflamed lips. Severe allergic reactions are rare but possible. If you develop rash, swelling, or trouble breathing, stop and get help.
Does propolis work for cold sores?
There's possibly effective evidence for herpes labialis (cold sores), both taken by mouth and applied topically. It's not a guarantee it'll work for you, but the data supports trying it.
Is it safe to use while pregnant or breastfeeding?
No. There isn't enough safety data during pregnancy, so it's best avoided then. While breastfeeding, there also isn't enough information. Talk with your doctor if you want to use it during either time.
Can I use this long-term?
The safety data covers short-term use well. For longer-term use, there's less information, so check with your pharmacist about how long you plan to take it.
What's in the liquid besides propolis?
Grain alcohol is used to preserve the propolis extract and carry it in liquid form. If you need to avoid alcohol, this product may not be right for you.
