Use every natural first aid in the game to heal their respective afflictions.
There are only three you need and that's Old man's beard wound dressing, Rose hip tea and Reishi tea
You have to use them to heal afflictions and not simply use them on nothing or the wrong ailment.
Old man's wound dressing is used for infections (comes with getting cut from attacks) *
Rose hip tea is used for pain relief (comes with spraining your ankle or wrist)
Reishi tea is for food poisoning (comes with eating gone-off food)
*Ironically because of the way you get infections, it is harder to do this on pilgrim.
