> Honeybees use 2-heptanone as a defense strategy, especially against > smaller hive invaders, including wax moth AND Varroa. Max When I read your very interesting paper recently on this subject it occurred to me that the analgesic properties of propolis might be more to do with the chemicals added by the bees than the plant resins from which it is made. Did you look into the possibility that propolis contains 2-heptanone or has propolis already been fully researched?
