By biting and consuming her chakra, Karin can heal the injuries of others as well as herself. This ability has been shown to heal even life threatening injuries in a short period of time, and is capable of quickly reenergising those Karin heals. However, this technique rapidly depletes her own 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.
