Propolis is the most important ‘chemical weapon’ of bees against pathogenic microorganisms, (sometimes also referred to `bee glue'), Bee glue’s chemical composition depends on the specificity of the local flora at the site of collection and thus on the geographic and climatic characteristics of this site. This fact results in the striking diversity of propolis chemical composition; however it composed mainly of 50% resin (composed of flavonoids; phenolic acids and esters), 30% wax, 10% essential oils, 5% pollen and 5% various organic compounds. Numerous studies carried out with the combined efforts of phytochemists and pharmacologists, led in recent years to the idea that different propolis samples could be completely different in their chemistry and biological activity. Propolis has been used as a remedy by humans since ancient times. It is still one of the most frequently used remedies for treatment of wounds and burns, sore throat, stomach ulcer, etc.,for this reason propolis has become the subject of intense pharmacological and chemical studies for the last 30 years.
