Propolis (Pro-before, Polis-city = defense of the city), is the resinous substance that bees gather from the leaf buds of trees and certain vegetables.
The bee gathers this and transforms it in order to disinfect the beehive, seal cracks, build panels, as well as using it as a microbiocidal agent, disinfectant and also for embalming intruders otherwise difficult to expel due to their size.
Due to the great number of active ingredients present, tincture (alcoholic extract) of propolis is well known and used for its therapeutic properties, principally for its stimulant action on the organism’s defense system. Notable amongst its properties are its antioxidant and anti-microbial action, its activity as a stimulant and its healing, analgesic, anesthetic and anti-inflammatory activity.
To date, in the literature consulted, no antioxidant capacity values have been found greater than those obtained for propolis, for any of the products/foods analyzed, using this type of methodology.
