Medical Ninjutsu

Medical Ninjutsu is a branch of ninjutsu associated with healing, as well as the manipulation of their own, or another's body, practiced by shinobi categorized as "medical-nin". The use of medical ninjutsu requires very advanced chakra control, as well as extensive knowledge on such things as herbs, medicines, the human body and even poisons.

Overview
The knowledge of medical ninjutsu can be used for a variety of purposes apart from simply healing. It can be used to create poisonous gas, deranging the target's nervous system, or directly attacking a target with chakra scalpels. Tsunade, renowned as the greatest medical-nin in the world, was able to apply the extreme chakra control required for medical ninjutsu to create chakra-enhanced strength, an ability she taught to her student, Sakura Haruno.

Ayame Rin, from the Land of Forests, makes incense to fill different purposes in battle, such as to poison, derange the target, heal the target or to affect the target's emotions.
