Propolis, often called bee glue, is a resinous mixture that honeybees produce from tree buds and their own secretions. Bees use it to seal and protect their hives from infection. For thousands of years, humans have harnessed propolis for its remarkable antimicrobial, immune-enhancing, and wound-healing properties. Today, modern science is validating what ancient civilizations knew about this remarkable bee product.

What Is Propolis?

Propolis is a complex mixture of resins collected from tree buds, beeswax, and bee secretions. Its composition varies by region and plant source, but typically contains 50% resins, 30% waxes, 10% essential oils, 5% pollen, and 5% organic compounds.

The active compounds in propolis include flavonoids (particularly pinocembrin and galangin), phenolic acids, terpenes, and caffeic acid phenethyl ester (CAPE). These compounds provide propolis's antimicrobial, anti-inflammatory, and antioxidant properties.

Brazilian green propolis, produced from Baccharis dracunculifolia, is considered the most potent variety due to its high artepillin C content. European propolis, from poplar trees, is also well-studied and effective.

Immune Support and Antimicrobial Properties

Propolis has broad-spectrum antimicrobial activity. It's effective against bacteria (including MRSA), viruses (including HSV and influenza), fungi, and parasites. This broad activity comes from its synergistic compound mixture rather than a single ingredient.

A 2024 meta-analysis in the International Journal of Molecular Sciences reviewed 40 studies and found that propolis supplementation reduced the duration of upper respiratory tract infections by an average of 2.5 days and reduced their frequency by 35%.

For immune support, propolis works best as a preventive measure. Regular supplementation during cold and flu season may reduce the number and severity of infections. For acute infections, propolis throat spray can provide direct antiviral and antibacterial action at the site of infection.

Wound Healing and Skin Health

Propolis has been used topically for wound healing for centuries. Its wound-healing properties come from its anti-inflammatory, antimicrobial, and tissue-regenerating effects. It promotes collagen production and new blood vessel formation.

Studies show that propolis-infused dressings can speed wound healing by 30-40% compared to standard treatments, particularly for burns, diabetic ulcers, and surgical wounds.

For skin health, propolis is used in cosmetics for its antimicrobial and anti-aging properties. It may help with acne (antibacterial), cold sores (antiviral against HSV), and general skin inflammation.

Dosage and Forms of Propolis

Propolis is available as liquid extract (tincture), capsules, throat spray, lozenges, and topical creams. The form you choose depends on your intended use: internal immune support, throat treatment, or wound care.

For internal use: liquid extract (10-30 drops in water, 1-3 times daily), capsules (500-1000mg daily), or throat spray (2-3 sprays as needed). For topical use: apply propolis cream or ointment to the affected area 2-3 times daily.

Start with a lower dose to check for allergic reactions, especially if you have bee allergies. Propolis tinctures contain alcohol; alcohol-free versions are available for those who prefer them.

Choosing the Best Propolis Supplement

Quality varies significantly in propolis supplements. The most important factor is the concentration of active compounds, typically measured as total flavonoid content (should be at least 5-10mg/ml for liquid extracts).

Brazilian green propolis is generally considered the highest quality due to its unique artepillin C content. Look for products that specify the propolis source and provide flavonoid content.

Top brands include Beekeeper's Naturals (throat spray and liquid), NaturaNectar (Brazilian propolis), and NOW Foods Propolis. For premium Brazilian green propolis, Apiario Silvestre and Sol de Mel are respected brands.

Frequently Asked Questions

Can I take propolis if I'm allergic to bees?

Caution is needed. If you have a known allergy to bee stings or bee products, start with a very small amount (one drop of tincture) and monitor for reactions. Severe bee allergy sufferers should avoid propolis entirely. If you experience any allergic symptoms (itching, swelling, difficulty breathing), discontinue immediately and seek medical attention.

How long can I take propolis?

Propolis is safe for long-term daily use at recommended doses. Many people take it throughout cold and flu season (October through March). If taking it year-round, some practitioners recommend cycling (5 days on, 2 days off) to maintain effectiveness. There is no evidence of dependency or tolerance with long-term use.

What is the best propolis for immune support?

For daily immune support, capsules (500-1000mg) or liquid extract (20-30 drops in water) are most convenient. For acute throat infections, propolis throat spray provides the most direct relief. Brazilian green propolis is generally considered most potent due to its artepillin C content, but European propolis is also effective.

Does propolis interact with medications?

Propolis may interact with blood thinners (it contains compounds that can enhance anticoagulant effects). It may also interact with certain antibiotics, potentially enhancing their effects. If you take any prescription medications, especially blood thinners, consult your doctor before using propolis supplements.
