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?
