If Narutopedia is anything to go by:
A technique that uses the refine chakra
control and concentration required in
medical ninjutsu to enhance one's strength
to monstrous levels. This is done by storing
chakra into one's hands or feet, and
releasing it onto the target with pinpoint
timing. With this strength, the user can
decimate the ground or even kill opponents
with a single strike. The training for
this application is quite arduous, as Tsunade
repeatedly came at Sakura with full force to
help her learn.
