re: #422 jcm
A while back a lizard posted an article that theorized a lot of the experimentation was done by shaman apprentices, the shaman looking for new cures and mind altering substances. The shaman would watch for reactions in the apprentice.
There is a method, taught in survival classes for determining if something is edible. Rub a little on your arm, watch for reaction, then rub a little bit inside the mouth, then taste and spit out, then eat a tiny bit.
That would be a hell of a task if you’re in Africa and the only thing around is an elephant…
