An instinctive behavior in both animals and humans when injured is to lick the wound. Saliva does contain anti-bacterial agents and possibly tissue factors that promote healing, but it's not generally recommended in Real Life given the possibility of infection and especially not after major surgery. Hence the existence of the Cone of Shame. Often used as an indication that My Instincts Are Showing.
