When you heal Pokemon at a Pokemon center, all hp and pp is restored.

Canadian health care duh

Probably. Pokemon are the only thing in the Pokemon world equivalent of America to have free health care, so it must be insanely easy to revitalize them when they are down

If you can create a medicine that instantly brings a creature to full potential, it's fully possible that the same is used as a rest point in each city/town to gather trainers and let them rest

The reason potions, etc. are still being sold is probably to keep the economy from not crashing due to how everything's free

Now the biggest mystery: How sleeping in a bed suddenly allows for the exact same health restoration as a nurse

How's that a mystery? Rest already restores all of the user's HP.
