Bee propolis is a substance that bees have used for thousands of years and humans have used it for centuries. It is created by honeybees from the bark and sticky buds of a range of trees and plants. Bees gather resin and bring it back to the hive, combine it with wax and transform it into propolis before utilising it to sterilise and protect the hive against infection. Comvita propolis is sourced from the resin of poplar trees which is known to be extremely rich in bioflavonoids – a special type of antioxidant known to help maintain a healthy immune system. Therefore many Comvita immune health products such as propolis throat spray and propolis capsules contain this active ingredient. Some of the original Comvita products like Propolis lozenges and Propolis throat spray have proved to be favourites during the winter months. Buy Comvita propolis products here.
