Since propolis components are dependent on the local plant sources and 
conditions, and propolis is a sponge for any contaminants,
I am often disturbed by articles that don't emphasize the unique nature 
of each batch.  I have natural food buffs thinking propolis is propolis 
is propolis, at least until I assure them that I'm not ingesting any 
propolis except that fully tested, or from my chemical free hives in a 
mostly national forest location.  I'd love to see more research to ID 
those components, if any, in all propolis and possible beneficial 
effects.  Not that I don't appreciate the work being done, just wish the 
caveat was included for the non-beekeepers.
