Remembers me at my university times, we had to make a herbary. It ended up everytime I went jogging through the woods around my home village that I thought often someting like this. Oh here we have some Taraxacum Cumoffi... in Latin and for it was good for and where to find more of it. A local peasant not to mention a healer hedgewitch would have such knowledge stored in his / her area knowledge.
A Outdoorsman or Survival Skill in that Low TLs would also have some of that knowledge.
Of course they would use Latin, but the local language.
