Propolis itself was NOT tested!Reply:Yes, understand and it's a shame ethanol was mixed with it, for certainly wouldn't want that in beehives as it would be non-orgnaic for sure.
But never-the-less 1993-1996 until we shook down for second regression, all we used for treatment of fouls, chalk, sac,nosema, etc., was propolis.Then spring of 1997 after making SC foundation with 4.9mm top tolerance, we shook down again fine tuning to get rid of secondary diseases.The hives were living with varroa, but as have said before needed to get back to production. Also we were told to prove it! and have stayed course!But it was simply ground up propolis frozen and in a coffee mill ground into powder and mixed into granulated honey in place of normal terrmycin treatment.Noting more!With regression to 4.9mm top tolerance levels of foul fell to 1-2% seeing and have stayed that way, never being a problem since! Dee A.
