A potion used in combat is "used" until the end of the combat, at which point it is discarded, along with all the other cards that modified the combat.

I do not believe it would be possible to use the same potion more than once in a combat through a mechanism which involved recovering discards, because by the time the potion was actually discarded, the combat would be over.
