Medical-nin

are ninja who specialize in medical treatment and use of medical-oriented jutsu to heal others. Becoming a medic-nin requires high intelligence and excellent chakra control. A medic-nin is trained to avoid getting injured in any way, for the reason that if they are injured, then there would be nobody to heal the other members of their team. Medic-nin accompany other ninja on high ranking missions to increase the survival rate of the squad. Medical-nin make use of the Mystical Palm Technique, a technique used in surgery. It allows them to make precise incisions and then doubles as a means to heal a wound. For more serious injures, multiple medic-nin could combine their efforts with Healing Resuscitation Regeneration Technique to use a portion of the patient's own body as a medium to help the healing process.

The knowledge of a medic-nin can be used for a variety of purposes. Hana Inuzuka is a veterinarian that specializes in the treatment of ninken. Chiyo, in the past, used her medicinal knowledge to create deadly poisons. Her efforts were often counteracted by Tsunade, the greatest medical-nin in Konoha, who is renowned for being able to cure any ailment which is why some people refer to her not only as Konoha's greatest medical-nin but the world's greatest medical ninja.

Field medic-nin (Konoha field medic-nin at least), when in the field or on the battlefield, are equiped with Medical Pouches in order to carry medical supplies as well as their weapons.
