Hi guys:
  I can surely attest to the white sugar thing.  In my Karate class was
a strange young man that raised fighting cocks.  He got spurred on the
back of his hand and it was not healing.  I told him about white sugar
and it was better in a few days.  One of my employees got a terrible
deep, puncture bite from his Rottweiler.  He put the sugar and a bandage
and in just a few days - gone.  Nothing will grow in white sugar
(althought honey works too, just not as well or as neatly)
