When a person has been afflicted by a pathogen or toxin, this medical ninjutsu can be used to draw out the agent and heal the damage. First the cause of the illness is determined by perceiving disturbances in the patient's chakra. Then, using a chakra scalpel, an incision is made into the affected part. Using their chakra, the medical-nin then draws out the agent, while simultaneously repairing the damage it caused.
After the agent is drawn out, it can be used to create an antidote or medicine, which can then be given to the patient to ensure a complete recovery. This technique requires the utmost care and ability in diagnosis and incising and unmatched chakra control. Therefore, it is considered an extremely difficult technique, even among medical ninjutsu.
