Me explaining to a medieval peasant how to make their heartburn go away: Drink from this spring, it balances your yellow bile humor. It has to do with the specific rocks that make up the underground spring the water resides in. They leech into the water and it neutralizes the excess yellow bile causing your pain.
Peasant with Bdellophobia due to the poor medical understanding of the time: I do not trust this water one bit anymore! Or you for that matter! AWAY WITH YOU FOUL PHYSICIAN!
