Flame away but I don't really find "healing puddles" to be either immersion breaking or unrealistic(at least no more unrealistic than casting magic spells etc).
Magic healing potions are just that "MAGIC". I don't see why the substance can't be absorbed through the skin and has to be drank in order for it to work.
Right...because walking through a puddle of magical liquid that heals you when ingested due to it's magical properties should be able to work as well if you pour it out on the ground and go stand in it while wearing boots.
