Mystical Palm Technique

The user applies their hand to a wounded part of the body and sends chakra into it, accelerating the body's natural healing abilities. Although its most obvious use is as a way of treating external injuries, it can also be used for internal illnesses. Users must be careful to only use as much chakra as is needed for the specific injury. If too much chakra is sent into the body, this can disrupt the body's circulation, putting it into a comatose state.

Because of the level of chakra control required to safely use this technique, few medical-nin can actually perform it; when Sakura Haruno is learning how to use it, she's shown practising on a fish. When Sarada Uchiha practised it on a fish, she sent too much chakra and caused it to eventually burn up. The anime states that the different hidden villages have all developed their own applications for this technique that are unknown to other villages; in Kirigakure's case, its medics can use it as a remedy for seasickness.

Trivia

 * The "senjutsu" in this technique's name is unrelated to the senjutsu used elsewhere in the series. In this technique's case, it is a reference to the secret of immortality the legendary real-life sages allegedly had.
 * This technique is possibly derived from the real-life spiritual practice of Reiki, commonly known as palm- or hands-on-healing.
 * Kabuto Yakushi has been shown using the Mystical Palm Technique from a short distance away, without directly touching the person he's healing.
 * Sakura is likewise shown healing an injury to herself, seemingly without using her hands at all.
