What Is Propolis? A Natural Compound with a Rich History
Origins and Traditional Use
Propolis, often called “bee glue,” is a natural resinous substance created by honeybees. Bees collect sticky materials from tree buds and plant sources, then mix them with beeswax and their own enzymes. The resulting substance serves as a protective coating inside the hive, sealing cracks, reinforcing structural stability, and helping maintain a clean, stable environment.
Its use dates back to ancient times. Historical records indicate that propolis was valued by Greek, Roman, and Egyptian civilizations. It was used to help preserve materials and support general cleanliness, and traditional wellness practices included it as a botanical agent for supporting health.
In Ayurveda and other long-established systems of well-being, propolis was included in tonics and preparations intended to support the body's natural balance. While traditions vary by region, their continued presence across cultures highlights their longstanding association with holistic practices.
Propolis and Its Bioactive Compounds
Polyphenols and Flavonoids
At the heart of propolis’s potential lies its rich content of polyphenols, a group of plant-derived compounds with antioxidant activity. Flavonoids, a major subclass of polyphenols, are particularly well studied. These compounds are found in many fruits, vegetables, teas, and wines, and they are known for their ability to help support cellular and oxidative balance.
The combination of flavonoids and other polyphenols in propolis contributes to its unique profile. When bees gather resins from plants, they bring back concentrated sources of these natural compounds, which then become part of the propolis mixture. This synergy of nature and bee behavior creates a powerful botanical resin that offers a wide array of potential wellness-supporting elements.
Common Flavonoids Found in Propolis
Some of the key flavonoids that have been identified in propolis include:
- Quercetin: Often studied for its antioxidant potential, quercetin is a compound found in apples, onions, and tea. In propolis, it contributes to the support of cellular balance.
- Chrysin: A naturally occurring flavone, chrysin is studied for its bioavailability and its potential to help support stress response systems.
- Galangin: Found in Alpinia officinarum and present in propolis, galangin contributes to its polyphenolic strength.
- Apigenin: A flavonoid with potential calming properties, apigenin is commonly associated with chamomile.
- Pinocembrin: One of the most abundant flavonoids in propolis, pinocembrin is widely studied for its role in supporting various physiological functions.
These compounds, collectively, may help support the body’s natural processes that protect against oxidative stress.
How Propolis Can Help Support Overall Well-Being
A Natural Source of Antioxidants
Propolis is widely recognized as a natural source of antioxidants - substances that can help support the neutralization of free radicals. Free radicals are reactive molecules that are naturally produced during metabolism. While they have useful roles in certain biological processes, an overabundance can affect cellular balance.
Antioxidants help support the maintenance of oxidative balance by donating electrons to free radicals without becoming destabilized themselves. By supporting this balance, propolis may contribute to general well-being, especially when combined with healthy lifestyle practices such as a nutrient-rich diet and regular physical activity.
Immune System Support
The natural compounds found in propolis, including flavonoids, phenolic acids, and essential oils, are under ongoing study for their potential to help support immune health. While more human research is needed, early findings in lab-based and animal studies suggest propolis may encourage balanced immune activity.
Many people choose to incorporate propolis into their seasonal wellness routines, especially during times of heightened environmental exposure. Because it contains a broad array of bioactive components, propolis is viewed by some as a valuable addition to a comprehensive approach to supporting immune resilience.
Seasonal Wellness
Changes in season can affect personal wellness. Cold, dry weather; increased time indoors; and environmental transitions may place extra demands on the body. Propolis is often included in seasonal health regimens for those seeking to support natural defenses and maintain consistent wellness.
Used as part of daily routines, through supplementation or topical products, propolis is one of many natural substances that may offer support during transitional times of the year.
Scientific Studies on Propolis
Clinical and Laboratory Research
Over the past few decades, propolis has attracted attention from scientists across fields such as pharmacognosy, microbiology, and integrative health. More than 2,500 articles and studies reference its composition and biological activities.
While clinical trials in humans remain limited, in vitro (cell-based) and in vivo (animal-based) studies have demonstrated interesting findings. These include its potential antioxidant and free radical-scavenging activity, as well as its support of biological equilibrium.
A review published in Oxidative Medicine and Cellular Longevity outlines multiple ways that polyphenol-rich substances like propolis may help modulate natural processes related to oxidative stress and cell signaling. These findings provide a basis for continued investigation into the supportive role of propolis in human health.
Geographic Variation in Propolis Composition
The chemical composition of propolis is not fixed; it varies depending on where the bees gather plant materials. This makes each type of propolis slightly different, influencing its potential applications.
- Brazilian green propolis is derived from Baccharis dracunculifolia, a native shrub. It’s rich in artepillin C, a phenolic compound studied for its support of oxidative balance.
- European propolis, particularly from the Balkans and Eastern Europe, is often based on poplar tree resins. It tends to be high in flavonoids like pinocembrin and galangin.
- Asian propolis may include resins from various tree species, contributing to its unique aromatic and phenolic profile.
This diversity is both a strength and a challenge for researchers. It means propolis is a highly adaptable substance, but also that standardization for supplementation requires careful sourcing and quality control.
American Propolis: Regional Characteristics and Growing Interest
In recent years, American propolis has gained attention as researchers and producers explore its unique regional attributes. Sourced primarily from temperate-zone flora across North America, American propolis typically contains resins from poplars, conifers, and a diverse range of deciduous trees. Its composition often mirrors that of European propolis, particularly in regions where poplar trees dominate, but with local variations that reflect the botanical biodiversity of the continent.
American propolis tends to be rich in flavonoids such as pinocembrin, chrysin, and galangin, as well as caffeic acid phenethyl ester (CAPE), a compound under study for its antioxidant and immune-supportive properties. Its composition may vary significantly between the Eastern and Western United States, depending on vegetation and seasonal patterns.
The growing demand for locally sourced wellness products has prompted beekeepers and natural product companies across the U.S. to invest in propolis harvesting and standardization. This has led to an increase in availability of American-made propolis supplements, oral sprays, and skincare products, offering consumers a regionally sourced option.
With its blend of familiar polyphenols and region-specific plant compounds, American propolis represents an emerging area of interest in both research and wellness markets. As sourcing practices improve and quality testing becomes more refined, American propolis may play a larger role in the broader landscape of natural health products.

A Closer Look at How Propolis Is Sourced
Bee Behavior and Resin Collection
Bees are remarkably selective in the materials they gather. When foraging for resins, they focus on trees with protective exudates, including poplars, birches, and conifers. These resins naturally serve as protective coatings for plants, and bees seem to instinctively select them for their own use.
Once collected, bees carry the sticky material in their pollen baskets and return it to the hive. There, worker bees mix the resins with wax and enzymes to form propolis which they then spread along hive surfaces and entrances.
Harvesting for Human Use
To collect propolis for human applications, beekeepers often use propolis traps, specialized screens that bees fill with resin. Once the screens are full, they are gently removed, and the propolis is scraped off.
This process is typically done during warmer months when resin production is high and bees are most active. Ethical sourcing ensures that bees are not overburdened or disturbed, and that enough propolis remains to protect the hive naturally.
The Future of Propolis Research
