Propolis is a natural substance made by honey bees to protect the hive. It has natural anti-viral and anti-fungal properties. It is commonly referred to as the immune system of the hive. The bees coat the entire inside of the colony with this substance collected from the resinous gums of trees and shrubs. These drops are made from raw propolis collected from our own colonies and extracted in small batches. Many people use propolis as part of their daily wellness routine. This product is made by hand on our working bee farm in Pennsylvania. Why buy from Greenway Apiaries? Small-batch hive goods made by Devon at Greenway Apiaries in Coaldale, Pennsylvania.
