Comvita Bee Propolis Throat Spray contains Propolis, which is created by bees from the natural resin produced by trees as part of their defense system. Honeybees collect the resin, mix in beeswax and enzymes, and use it to protect the hive. Comvita Propolis contains a range of bioflavonoids along with 10% UMF 10+ Manuka Honey. Manuka Honey is gaining worldwide recognition for its unique properties. We collect propolis from our hives, using it as a key ingredient in many of our products.
