Heal Bite

Through biting and consuming the user's chakra, the user can heal the injuries of others, as well as themselves.

Overview
This ability has been shown to heal even life threatening injuries, and is also capable of quickly restoring the stamina those healed. This technique, however, rapidly depletes the user's own chakra reserves, and is left with a permanent bite mark every time one uses it. Due to its depletion of chakra, it is dangerous for one to use this ability too regularly as Karin normally refrains from doing so more than once a day.

Trivia

 * Karin has many bite marks spread throughout her arms, chest, and neck, implicating that she has used this ability repeatedly in the past.
