I think it is interesting and a little ironic that the 'grand decline' of 4th edition D&D actually handles this mechanic rather well, and I would argue, better than 3rd edition.
Each player has a number of 'healing surges' which are determined primarily by class and constitution.
It's anything but handling it well. It's completely abstract, gamist shit, dissociated from any sort fo in-universe meaning or sense.
Slow acting potions make sense, or at least more sense than instahealing ones,
potion toxicity may make sense, same with other ways of limiting the amount of potions that could be ingested at once.
