Propolis: Alternative Medicine for the Treatment of Oral Microbial Diseases

Bees are arthropods of Hymenoptera order and are classified into two groups based on their type of life: solitary and social life. Propolis is produced by bees that live socially, from the harvesting of products derived from plants and used to seal and protect the hive against intruders and natural phenomena [1]. Propolis term derives from the Greek Pro, "opposite, the entry" and polis, "city or community" [2,3]. Propolis is a natural substance collected by Apis mellifera bees in several plant species. It has been used in folk medicine for centuries [2,4]. Characteristically, it is a lipophilic material, hard and brittle when cold, but soft, flexible and very sticky when warm. Hence the name "beeswax" [5]. It has characteristic odor and shows adhesive properties of oils and interact strongly with skin proteins [6]. The composition of propolis is complex [7,8]. Some factors, such as the botanical origin of propolis and its time of collection can influence the chemical composition of this resinous material [9]. The color of propolis varies from yellowish green to dark brown, depending on location - savannah, tropical forests, desert, coastal and mountainous regions - where it is produced. [10,11,12]. Propolis is used by bees to protect against the entry of microorganisms, fungi and bacteria in the hive, and as a sealing material for preventing the entry of light and moisture inside. It is also used to line the comb, to allow the deposition of eggs by the queen, and to embalm small dead animals (beetles and insects) that usually bees could not take into the hive, preventing its putrefaction.3,5,7].
