HelloPharmacist Scorecard of Ultra Clear Propolis Liquid by CATALO

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.

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.

Ultra Clear Propolis Liquid contains one active ingredient: propolis extract (natural). Propolis is a resinous compound that bees collect and use to seal their hives.

The product also contains inactive ingredients — humectant, purified water, anethole, and peppermint oil — which serve as the liquid base and flavoring.

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: Relieve cold and flu symptoms, soothe throat, enhance immunity.
  • We looked for evidence on: Common cold, Upper respiratory tract infection (URTI), Oral mucositis, Canker sores, Herpes labialis (cold sores), Gingivitis — 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 has possibly effective evidence for two uses: oral mucositis (inflammation and ulcers in the mouth from cancer treatment or other causes) and herpes labialis (cold sores). For diabetes, the evidence is also rated possibly effective.

The data we hold does not establish effectiveness for dengue fever — evidence is insufficient to rate it.

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. The most common side effect when taken by mouth is mild headache; around 7% of patients in one trial reported this at 250 mg twice daily over 4 months.

Topically or in lozenges, it can cause contact dermatitis or allergic cheilitis in sensitive people. Rare but serious allergic reactions are possible, especially in people allergic to bees or bee products — stop and seek help if you experience severe symptoms.

Due to insufficient safety data, propolis is best avoided during pregnancy and while breastfeeding. If you're pregnant, nursing, or planning either, talk with your pharmacist or doctor before taking this product.

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, check your exact medications if you take blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel, etc.), warfarin specifically, or any drug metabolized by your liver through CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP2E1, or CYP3A4 pathways. All of these carry Moderate risk.

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 inflammation from cancer treatment, or blood sugar control, but the evidence is still limited. If you take blood thinners, warfarin, or medications your liver metabolizes, check with your pharmacist first — this product could interfere.

Anyone allergic to bee products should avoid it entirely.

Propolis Extract, Natural8 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.

Ultra Clear Propolis Liquid by CATALO: Common Questions

Does Ultra Clear Propolis Liquid by CATALO interact with any medications?
Yes. Based on its ingredients, Ultra Clear Propolis Liquid 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?
Ultra Clear Propolis Liquid 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.
What's propolis, and why is it in this product?
Propolis is a natural resin bees make to seal their hives. Research suggests it may help with cold sores, mouth ulcers (especially from cancer treatment), and blood sugar control — which is why it's the active ingredient here.
Can I take this if I have a bee allergy?
No. Propolis is a bee product, and people allergic to bees or bee products are more likely to have allergic reactions to it, including severe ones. Avoid it if you're allergic to bees, honey, or other hive products.
What side effects should I watch for?
Mild headache is the most common — about 7% of people reported it in trials. Contact dermatitis (rash or skin irritation) can occur with topical or lozenge forms, especially in sensitive folks. Rare severe allergic reactions are possible; stop and seek help if you have trouble breathing, swelling, or severe itching.
Is this safe during pregnancy or breastfeeding?
No — there isn't enough safety data. Propolis is best avoided if you're pregnant or breastfeeding. Talk with your pharmacist or doctor about whether it's right for you in these situations.
Does this really work for cold sores?
The evidence says propolis is possibly effective for cold sores, so there's promise — but it's not a proven cure. Results vary, and more research is needed to confirm how well it works.
