Well you can use granulated sugar too, I just had an abundance of the powder kind because it was Christmas. Sugar in a wound does multiple things. One: if you have bleeding going on it dissolves in the blood and thickens it right away. Two: often times with an injury you have the circulation system compromised. Cells need three things to live, water, sugar to burn for energy, and oxygen to burn the sugar. Usually the cells in a wound can get enough oxygen right out of the air unless it is a deep puncture wound. But if the blood supply has been comprised you will have cell death before the blood circulation can be restored. So you use sugar that once dissolved in the blood will cross the damaged cell walls. This will keep the cells living till hopefully the circulation system can be repaired. This reduced the cell death which helps to keep infection down.
