Wound Licking - in Humans

In Humans

In an unusual case, an Oregon teacher was reprimanded after licking blood from wounds on a track team member's knee, a football player's arm, and a high school student's hand. An Oregon public health officer commented that "We do know that animals lick their own wounds, and it may be that saliva has some healing properties. But my very strong recommendation is that you confine yourself to licking your own wounds."
