What it is
Propolis is a resinous substance collected by honeybees from tree buds, sap flows, and other botanical sources. Bees use it to seal cracks in the hive, embalm intruders, and maintain hive sterility. The composition varies dramatically by geographic region and season because bees collect resin from different local plants. Brazilian green propolis (from Baccharis dracunculifolia) is particularly rich in artepillin C and is the most studied form. Propolis contains over 300 compounds including flavonoids (galangin, quercetin), phenolic acids (caffeic acid, ferulic acid), and terpenes. It has been used in traditional medicine for wound healing, sore throats, and dental infections for thousands of years.
