Perhaps propolis, a mixture bees make for weatherproofing and inhibiting bacteria should not be mixed into concoctions that would trick bees into consuming it.  It is certainly not a natural food of the bee which brings its use as a <<<treatment>>>> in this manner into question as far as organic beekeeping is concerned.  Even though it is a product the bees make, it is perhaps unnatural for them to consume it, and may do harm to the bee, especially in quantities that might do harm to their own beneficial bacteria found in the gut of the bee.

A treatment is a treatment, and I believe these things should not be used until they have been tested and approved for use as a treatment in bee colonies.  If propolis does have AFB inhibiting qualities, the use of such a treatment would mask real performance, and make selection of AFB resistant traits more difficult.  

What happened to breeding bees?

Best Wishes,

and yet it is useless to try and argue the matter with the bee.”
