Propolis is a resin-like substance that bees make from tree buds and sap, and it has genuine benefits for oral health, wound healing, blood sugar management, and fighting certain infections. Bees use it to seal and protect their hives, and humans have used it medicinally for thousands of years. Modern research is catching up, and while propolis isn’t a cure-all, several of its uses now have solid clinical evidence behind them.
What makes propolis biologically active is its dense concentration of plant-derived compounds. Chemical analyses have identified over 90 distinct compounds in propolis, including flavonoids like naringenin and kaempferol, phenolic acids like gallic acid and caffeic acid, and terpenoids. These compounds work individually and together to produce antimicrobial, antioxidant, and anti-inflammatory effects throughout the body.
Oral Health: Plaque and Gum Inflammation
One of the strongest areas of evidence for propolis is dental health. A systematic review and meta-analysis of randomized controlled trials found that propolis mouthwashes produced large, statistically significant reductions in both dental plaque and gum inflammation. The effect on gum inflammation was especially striking, with propolis performing not just well, but in some trials outperforming chlorhexidine, the gold-standard antiseptic mouthwash used in dentistry.
The way propolis works in the mouth is straightforward: its antimicrobial compounds disrupt the bacterial biofilms that form plaque, while its anti-inflammatory properties calm irritated gum tissue. In one trial, after 21 days of use, participants using propolis mouthwash showed greater reductions in both plaque and gum inflammation scores than those using chlorhexidine or placebo. If you’re looking for a natural addition to your oral care routine, propolis-based mouthwashes or toothpastes are among the best-supported options.
Wound Healing and Skin Repair
Propolis has a long history in folk medicine as a wound treatment, and the science supports it. Applied topically, propolis helps wounds heal through several overlapping mechanisms: it prevents infection at the wound site, neutralizes free radicals that damage recovering tissue, and tamps down excessive inflammation that can slow healing. Beyond those protective effects, it actively promotes wound closure by stimulating collagen production, new cell growth, and the formation of new blood vessels (a process critical for delivering oxygen and nutrients to healing tissue).
Research on burn injuries specifically has shown propolis to be a promising treatment for managing the inflammatory response while supporting tissue regeneration and remodeling. Propolis creams and ointments are widely available and commonly used for minor cuts, burns, and skin irritation.
Cold Sore and Herpes Lesion Treatment
Topical propolis has shown remarkable results against herpes simplex virus (HSV) lesions, including cold sores and genital herpes outbreaks. A meta-analysis published in the Journal of Ethnopharmacology found that the healing properties of propolis were superior to acyclovir, the standard antiviral medication used for herpes. The difference was highly significant statistically, with propolis promoting faster re-epithelialization (the regrowth of skin over the ulcer) in both oral and genital lesions.
This doesn’t mean you should throw out your antiviral prescription, but it does suggest that propolis-based lip balms or topical ointments can be a genuinely effective option for managing cold sores, either alone or alongside conventional treatment.
Blood Sugar Regulation
Propolis supplementation has shown measurable effects on blood sugar. In a clinical trial where 34 healthy volunteers took 1,000 mg of propolis daily for 60 days, fasting blood glucose dropped from an average of 101.9 to 92.7 mg/dL, a statistically significant decrease. HbA1c levels, which reflect average blood sugar over the previous two to three months, also decreased.
There are important caveats. The same study found no significant effect on insulin levels or insulin resistance, meaning propolis may influence blood sugar through pathways other than improving how your body responds to insulin. The study also noted a slight increase in body weight and BMI over the 60-day period. For people already managing diabetes or prediabetes, these results are interesting but far from a reason to change your treatment plan.
Respiratory Symptom Relief
Propolis has shown benefit for common respiratory symptoms. Clinical observations have found that propolis syrup reduced dry cough, sore throat, chest pain, and overall breathing difficulty in patients with viral respiratory infections, with statistically significant differences compared to those who didn’t receive it. The effect likely comes from propolis’s combined anti-inflammatory and antimicrobial activity in the throat and upper airways. Propolis throat sprays and lozenges are among the most popular forms of propolis supplements for this reason, especially during cold and flu season.
Not All Propolis Is the Same
Propolis composition varies dramatically depending on where bees collect their resin. Brazilian green propolis, the most widely studied variety, is rich in prenylated compounds (notably artepillin C) sourced from a specific plant in the daisy family. Brazilian red propolis has a completely different chemical fingerprint, dominated by isoflavonoids from a legume tree. Black propolis varieties contain triterpenoids and prenylated flavones not found in other types.
These differences matter because they change what the propolis is best at. Green propolis tends to be emphasized in antioxidant and anti-inflammatory research, while red propolis has attracted attention for its unique isoflavonoid content. When buying propolis supplements, knowing the source and type can help you choose a product aligned with the research you’re most interested in. European and North American propolis, often called brown or poplar-type propolis, has its own distinct profile heavy in classic flavonoids like chrysin and pinocembrin.
How to Take Propolis
In clinical studies, oral propolis has most commonly been used at doses of 400 to 500 mg daily, with some trials going up to 1,000 mg daily for periods of up to 13 months. It comes in capsules, tinctures (liquid extracts), throat sprays, lozenges, and topical products like creams, ointments, and gels. Mouthwashes containing propolis extract are widely available for oral health use.
Tinctures offer flexible dosing and faster absorption, while capsules are more convenient and avoid the strong, resinous taste. For skin applications, look for creams or ointments with propolis extract rather than raw propolis, which can be difficult to work with.
Allergies and Safety Concerns
Propolis allergy affects roughly 1.9% of the general population based on patch testing data from a large multicenter survey. The most common cross-reactivity is with balsam of Peru (40% of propolis-allergic individuals also react to it) and rosin (27.2%). Cross-reactivity with beeswax is actually rare, at only 7.2%, so being sensitive to propolis doesn’t necessarily mean you’ll react to other bee products.
If you have asthma, be cautious. Propolis has been identified as a potential trigger for allergic reactions that can worsen asthma symptoms. The Cleveland Clinic notes that propolis’s natural origin doesn’t make it risk-free, and people with known allergies to bee products or tree resins should test a small amount first or avoid it altogether. If you’re taking blood-thinning medications, talk to your pharmacist before adding propolis, as some of its compounds may enhance anticoagulant effects.
