Power of the White Snake

The is a general term on Orochimaru's ability to heal any injuries, due to his years of experimentation on his own body to extend his lifespan and survival rate, turning him into a giant white snake that enables him to utilise Living Corpse Reincarnation on a victim when the time is right. Aside from increased regeneration, Orochimaru can also reconnect his body with snakes should it be bisected, or if the injuries are too severe to heal, he can shed his skin to regurgitate a new body, free from all damage.

When he absorbed Orochimaru, Sasuke Uchiha temporarily acquired much of the White Snake's ability to heal faster than normal, as well as shedding his skin to escape the Amaterasu, though the latter feat took a toll on Sasuke's chakra reserves. Kabuto also obtained the ability by transfusing his master's genetic material into himself prior to Orochimaru's revival.

The Power of the White Snake is conferred by the White Snake Sage of Ryūchi Cave, by biting a person and injecting them with its natural energy. Those who survive are deemed worthy of being taught Sage Mode.
