You might try some stuff called Calendula gel. It's made from marigold flowers, which are edible (not that I would eat them, lol). My vet once told me to use some on a scrape my rat had over his eye. I picked some up at the grocery store. It's a clear gel that is soothing to cuts, burns, and bites. Obviously you should use a VERY small amount.
