A glue-like substance used by bees for building and protecting their hives, propolis at first glance appears to be an unlikely medicinal remedy. But the wide range of healing properties attributed to this sticky substance make it effective for everything from canker sores to cancer, and it’s one of my favorite natural remedies. In fact, I attribute my quick and complete recovery last year from a serious staph infection (contracted from a public hot spring swimming pool) in great part to propolis.
