If 90% of the conditions you ever have to treat are fever, hypothermia, runny noses, and dehydration, then I imagine hot/cold/wet/dry will get you pretty far.
(Runny nose? Here, take some drying herbs, and try not to sneeze on other people. Feverish? Bathe in cool water and take these cooling herbs. Losing water due to dysentery? Drink clean water with salt. Fell in the icy lake? Here, have a thermal support puppy.)
