One of the most well-documented products from the honey bee, propolis (also called Russian penicillin or bee glue) is known in countries outside the United States as a powerful, natural antibiotic. The former Soviet Union performed many scientific studies on the effects of propolis. This sticky, brown resinous substance is collected by honeybees from various plants and mixed with wax to sterilize their home against infection and for use as a multi-purpose cement and varnish. Propolis is harvested from the beehive and is made available in various forms to be used internally or externally. Propolis is available in capsule and tincture form to be taken internally to help fight infections. Because of its antibacterial and antifungal qualities it is a frequent ingredient in salves, lozenges, chewing gum and toothpastes.

Exact dosing recommendations cannot be made due to differences between various products. Capsules of 500mg are often recommended from 1 to 4 times daily. Follow product directions or your doctors instructions.

While the claim is seen that propolis has proven safe for human use, caution is advised for people sensitive to bee stings. Some of those allergic to bee stings have allergic reactions to propolis as well. Furthermore, people suffering from bronchial asthma and eczema may be more sensitive to bee products. It is not yet proven whether propolis itself or protein residues left by bees in propolis cause these allergic reactions. Another bee product, royal jelly, is associated with a higher risk of serious allergic reactions. Most such reports regarding royal jelly have been in asthma sufferers.
