after washing it I would use spider webs
theyre good for clotting the blood if its not horrific.
my gramma was bit by horse and grampa used sipderwebs on her chin until he get her to teh dr.
and he let the dog lick it first, to clean it. (eww but true)
and if u use grass, thats been rubbed into a lather, it can be used as disinfectant... I think...
