Heal Bite

By having others bite into her skin and suck out her chakra, Karin can heal other's wounds. This ability has been shown to heal even life threatening injuries in a short period of time, and is capable of quickly energising those Karin heals. However, this technique rapidly depletes her chakra reserves, and Karin is left with a permanent bite mark every time she uses it. Karin has many bite marks spread throughout her arms, chest, and neck, implicating that she has used this ability repeatedly in the past. Due to its depletion of chakra, it is dangerous for her to use this ability more than once a day.

During the Fourth Shinobi World War, Karin displayed the ability to also heal herself from the easily fatal wounds caused by Spiral Zetsu's Wood Release: Cutting Technique by simply biting her own arm.
