Propolis (bee glue) is a resinous product collected by bees and used to, among others, fill in holes in honeycombs, reinforce and seal the beehive, protect its entrance from insects and create proper hygienic conditions. Propolis is a sticky substance which is resin collected from tree buds, mixed with beeswax and saliva.
From all bees’ products, propolis features the most varied composition and shows thus great biological activity. The most important constituents of propolis include polyphenols (phenolic acids and flavonoids) and terpenoids (steroids and mono-, tri- and sesquiterpenes).
Therapeutic properties of propolis have been used since ancient times. It is well known particularly for its antibacterial (it is called a natural antibiotic), hepatoprotective, anti-inflammatory and immune-boosting properties.
Preparations based on propolis are very effective against colds, viral, fungal and bacterial infections and inflammation (both local and systemic).
