Bee propolis is a resinous mixture that honey bees collect from tree buds, sap flows, or other botanical sources. It is used as sealant for unwanted open spaces in the hive. Propolis is used for small gaps (approximately 6 millimeters (0.24 in) or less), while larger spaces are usually filled with beeswax. Its color varies depending on its botanical source, the most common being dark brown.
The basic components of natural propolis include: resin complex 39% — 53%, polyphenols 12% — 17%, polysaccharides 2% — 3%, beeswax 19% — 35%, impurities (including pollen, etc.) 8% — 12%. Bee propolis contains rich active substances, such as total flavonoids, total phenolic acids, terpenes, which offer antibacterial, anti-inflammatory, antipruritic, antioxidant, immune enhancement, hypoglycemic, lipid-lowering, anti-tumor and other functions.
