Medical Ninjutsu

is a branch of ninjutsu associated with healing, as well as the manipulation of their own, or an enemies' body practised by medical-nin. The use of medical ninjutsu requires very good chakra control, as well as extensive knowledge on such things as herbs, medicines, the human body and even poisons. The knowledge of medical ninjutsu can be used for a variety of purposes apart from pure healing, such as creating and treating poisons as seen with Shizune who uses her extensive medical knowledge to create a poisonous gas, performing autopsies or surgeries, or attacking a person's body directly, deranging the target's nervous system or sending them into a comatose state by overriding their body with chakra. Medical Ninjutsu in itself can also be used offensively, witnessed in Kabuto Yakushi's use of chakra scalpels in battle. Tsunade, the most celebrated medical-nin in the world, was able to applicate the extreme chakra control required for medical ninjutsu to engineer chakra-enhanced strength, something she has taught to her student Sakura Haruno as well.
