Antiviral effects of Scaptotrigona postica propolis and their fractions

Studies about viral infections have a great importance in human and veterinary health, and the number of medications available to treatment these diseases is very reduced, making the search for antiviral molecules an important focus for scientific research. Propolis is a bee material manufactured by the mix of exudate of plants, saliva and bee wax. This product is used to seal the hive and involve dead invaders. Their chemical profile is very variable, and depending on the geographic origin and plant conditions of growth. The use of propolis (bee-glue) for various purposes has reports at before Christ.
