Healing Chakra Transmission

A technique in which the user channels his or her medical chakra through a medium - either a summoned animal or a special seal on the ground - who transfers it to the wounded person, healing them. This technique allows the user to heal an enormous number of people at the same time regardless of distance. If he or she runs out of normal chakra, they can then use her reserves to continue the technique. While using this technique, the user is apparently also able to communicate directly with the summoned animal, should they have used one, as well as have a sense of what the animal experiences as seen with Tsunade's reaction after Katsuyu finds Kakashi on the battlefield.
