As you might have noticed or not (if not, you have now!), Black and White bring us impressive, vast routes. Game Freak wanted to prevent us running back and forth to the PokéCenter and having to backtrack all the way. So in order to do that they came up with "Doctors and Nurses."
On some routes you will be battling a Doctor or a Nurse. If you beat these trainers, they'll heal you every time you talk to them. What a nifty feature!
