Bee propolis is one of the most chemically complex and biologically active substances produced by any living organism. Bees collect resinous material from tree buds, bark, and plant exudates, mix it with beeswax and salivary enzymes, and use the resulting compound to seal, sterilize, and protect their hive from bacteria, fungi, viruses, and environmental threats. The same antimicrobial, antioxidant, and anti-inflammatory properties that make propolis essential to hive health have made it one of the most studied natural health products in modern nutritional science.
This guide explains what propolis is, what its primary bioactive compounds do, what the clinical evidence says about its benefits, and how to choose between the three available formats: capsules for daily systemic supplementation, alcohol-free drops for flexible liquid dosing, and throat spray for targeted oral and throat application.

What is Bee Propolis and How Do Bees Make It?
Propolis (from the Greek pro, meaning "before" or "in defense of," and polis, meaning "city") is a resinous mixture that honey bees (Apis mellifera) collect from plant sources and process into a protective compound used throughout the hive. The word itself reflects propolis's primary function: defending the colony.
How Bees Make Propolis
Worker bees collect resinous exudates from tree buds (particularly poplar, birch, pine, and alder), bark wounds, and plant secretions. They mix this raw resin with beeswax (secreted from their own wax glands), salivary enzymes (including beta-glucosidase, which activates certain bioactive compounds), and pollen. The resulting propolis is a sticky, resinous material that varies in color from yellow-green to dark brown depending on the plant sources available in the local environment.
How Bees Use Propolis
Propolis serves multiple critical functions in the hive:
- Sealing and insulation: Fills gaps and cracks in the hive structure, maintaining temperature and humidity
- Sterilization: Lines the interior of the hive with a thin propolis coating that creates a sterile environment, reducing bacterial and fungal contamination
- Mummification: When a predator too large to remove (such as a mouse) dies inside the hive, bees encase it in propolis to prevent decomposition and contamination
- Entrance defense: Narrows the hive entrance to a defensible size and coats it with antimicrobial propolis
The Primary Bioactive Compounds in Propolis
Propolis is one of the most chemically complex natural substances known, containing over 300 identified compounds. The primary bioactive compound classes include:
Flavonoids (15 to 20% of propolis by weight)
- Pinocembrin: The most abundant flavonoid in propolis; potent antimicrobial, antifungal, and anti-inflammatory activity; inhibits bacterial cell wall synthesis
- Chrysin: Anti-inflammatory, antioxidant, and anxiolytic flavonoid; inhibits aromatase
- Galangin: Potent antioxidant and antimicrobial; inhibits bacterial DNA gyrase
- Quercetin: Broad-spectrum antioxidant, anti-inflammatory, and antiviral flavonoid
- Kaempferol: Antioxidant and anti-inflammatory with Nrf2-activating properties
- Apigenin: Anti-inflammatory and anxiolytic flavonoid
Phenolic Acids and Esters
- CAPE (Caffeic Acid Phenethyl Ester): Potent NF-kB inhibitor, antioxidant, antitumor, and immunomodulatory activity
- Caffeic acid: Antioxidant and anti-inflammatory phenolic acid; precursor to CAPE
- Ferulic acid: Antioxidant with UV-protective and anti-inflammatory properties
- p-Coumaric acid: Antioxidant and antimicrobial phenolic acid
Why Canadian Propolis: Apis mellifera and Northern Hive Quality
All three Nutridom propolis products are sourced from Canadian Apis mellifera (European honey bee) hives. Canadian propolis is predominantly poplar-type propolis, characterized by:
- High flavonoid content: Poplar resin is exceptionally rich in pinocembrin, chrysin, and galangin, making Canadian propolis among the most flavonoid-dense propolis types globally
- High CAPE content: Canadian poplar-type propolis contains significant concentrations of CAPE, one of the most pharmacologically active propolis compounds
- Consistent composition: Dominance of poplar as the primary resin source produces more consistent propolis composition compared to tropical types
- Clean sourcing environment: Canadian hives benefit from lower pesticide exposure and less industrial pollution
Benefit #1: Antioxidant Protection
Providing antioxidants for the maintenance of good health is the primary Health Canada-approved use of all three propolis products. Propolis provides antioxidant protection through multiple complementary mechanisms: direct free radical scavenging, metal chelation, Nrf2 activation, NF-kB inhibition, and lipid peroxidation prevention.
A randomized controlled trial published in Food and Chemical Toxicology (2011) found that propolis supplementation significantly increased plasma antioxidant capacity and reduced oxidative stress markers in healthy adults after 4 weeks. Research published in the Journal of Ethnopharmacology (2013) demonstrated that propolis extract had significantly higher antioxidant activity than vitamin C and vitamin E at equivalent concentrations.
Benefit #2: Immune System Support
Propolis modulates immune function through macrophage activation, natural killer cell enhancement, T-lymphocyte modulation, interferon induction, and complement system activation.
A randomized, double-blind, placebo-controlled trial published in Evidence-Based Complementary and Alternative Medicine (2011) involving 122 children found that propolis supplementation significantly reduced the incidence of acute respiratory tract infections, reduced illness duration, and reduced antibiotic use over a 6-month winter period. A randomized controlled trial published in Phytomedicine (2016) found that propolis extract reduced recovery time from upper respiratory tract infections by 2 days compared to placebo.
Benefit #3: Sore Throat Relief and Oral Health
Propolis addresses sore throat through antimicrobial activity against Streptococcus pyogenes, anti-inflammatory reduction of IL-1beta, TNF-alpha, and IL-6, mild local anesthetic effects, and mucosal protective film formation.
Beyond sore throat, propolis has been studied for dental caries prevention (inhibits Streptococcus mutans), gingivitis (significant reductions in gingival inflammation in clinical trials), oral ulcers (accelerated healing), and oral Candida (antifungal activity against Candida albicans).
Benefit #4: Antimicrobial Activity
Propolis has documented activity against bacteria, fungi, viruses, and protozoa through cell membrane disruption, cell wall synthesis inhibition (pinocembrin), enzyme inhibition, and biofilm disruption.
A systematic review published in Phytomedicine (2017) analyzing 94 studies found propolis demonstrated antibacterial activity against 21 bacterial species, with particularly strong activity against Staphylococcus aureus (including MRSA), Streptococcus species, Helicobacter pylori, and Mycobacterium tuberculosis. Antiviral activity has been demonstrated against influenza A and B, herpes simplex virus, adenovirus, and rhinovirus.
Benefit #5: Anti-Inflammatory Effects
CAPE is one of the most potent natural NF-kB inhibitors identified, reducing the production of over 150 pro-inflammatory genes simultaneously. Multiple propolis flavonoids (quercetin, kaempferol, apigenin) also inhibit COX-2, the enzyme responsible for producing pro-inflammatory prostaglandins, through a gentler multi-compound approach without the gastrointestinal side effects of pharmaceutical COX-2 inhibitors.
Benefit #6: Blood Sugar Balance
Propolis flavonoids inhibit alpha-glucosidase (slowing post-meal glucose absorption), CAPE improves insulin receptor signaling, and propolis antioxidants protect pancreatic beta-cells from oxidative damage. A randomized controlled trial published in Phytotherapy Research (2016) found propolis supplementation significantly reduced fasting blood glucose and HbA1c in patients with type 2 diabetes compared to placebo.

Frequently Asked Questions
What is bee propolis good for?
Bee propolis is Health Canada approved as a source of antioxidants for the maintenance of good health. Clinical research also supports its use for immune system support, sore throat and oral health, antimicrobial activity against bacteria and fungi, anti-inflammatory effects, and emerging evidence for blood sugar balance. It contains over 300 bioactive compounds including flavonoids (pinocembrin, chrysin, quercetin), CAPE, and phenolic acids working through complementary mechanisms.
What is the difference between propolis drops and propolis throat spray?
Both use Canadian Apis mellifera propolis in an alcohol-free glycerin base. The drops (NPN 80082267) are administered by counting 12 to 24 drops daily, either sublingually or mixed into water, providing flexible dosing and both local oral contact and systemic absorption. The throat spray (NPN 80082268) delivers propolis directly to the back of the throat with each spray, making it more convenient for targeted sore throat applications and on-the-go use.
Why is alcohol-free propolis better?
Alcohol is drying and irritating to mucous membranes, counterproductive for sore throat applications, not suitable for children or pregnant women, and causes a burning sensation on inflamed tissue. The Nutridom drops and spray use vegetable glycerin instead, which is gentle, non-irritating, naturally sweet-tasting, suitable for all ages, and has mild moisturizing properties that complement propolis's soothing effects.
Can I be allergic to propolis?
Yes. Propolis can cause hypersensitivity reactions in individuals allergic to bee products, poplar tree products, or balsam of Peru. Consult a healthcare practitioner before use if you have any of these allergies. Start with a small test dose and monitor for any reaction (skin rash, itching, swelling, difficulty breathing). Discontinue immediately if any hypersensitivity reaction occurs.
How long does it take for propolis to work?
For acute applications (sore throat), propolis throat spray can provide local soothing effects within minutes. For immune support and antioxidant benefits, consistent daily use for 2 to 4 weeks is typically required. All three products specify to consult a healthcare practitioner for use beyond 1 month.
Which propolis format should I choose?
Choose the 500mg capsules for the highest per-dose propolis content, a tasteless once-daily capsule, and a 120-day supply. Choose the alcohol-free drops for flexible dosing or mixing into beverages. Choose the alcohol-free throat spray for sore throat, oral health, or on-the-go targeted throat application.
Is propolis the same as honey?
No. Propolis and honey are both produced by bees but are entirely different substances. Honey is produced from flower nectar and stored as food. Propolis is produced from plant resins and used to seal and sterilize the hive. Propolis contains flavonoids, CAPE, and phenolic acids not found in honey, with significantly greater antimicrobial and antioxidant potency.
Can children use propolis?
The Nutridom propolis products are labeled for adult use. Parents considering propolis for children should consult a healthcare practitioner before use, particularly given the allergen risk and the importance of appropriate dosing for children's body weight. The alcohol-free drops and spray formats are more appropriate than alcohol-based tinctures if a healthcare practitioner approves their use.
Conclusion
Bee propolis is one of nature's most remarkable substances: a complex mixture of over 300 bioactive compounds refined over millions of years of evolution to protect one of the most densely populated living environments on earth. Canadian Apis mellifera propolis, sourced from poplar-rich northern hive environments, is among the most flavonoid-dense and CAPE-rich propolis types globally.
