Bee Propolis is a resin-like mixture that honey bees produce from the sap of tree buds. When they combine the sap with their own enzymes and beeswax, they create propolis, a sticky, greenish-brown product used as a coating to build their hives. It contains natural antibacterial, antiviral and antifungal properties. It also has anti-inflammatory effects on the skin. Propolis is used for swelling and inflammation.
