Well we haven't seen many medical nin but from what can tell only people with a high level of chakra control can learn this healing method, after they master it they use it to heal themselves and their team members during combat. As for their style of fighting they all seem to have their individual one almost always based on a technique that itself requires a high degree of chakra control ( tsunade's and sakura's power kicks and punches, kabuto's "scalpel hands", shizune's poison attacks, etc )Originally Posted by Buffalobiian
