I get the impression that the Everfree Forest is Forbidden Territory about the mysteries of which only certain brave souls like Zecora knew anything before this episode. Oh... and Celestia; she probably knows everything about the forest and its various creatures but has this infuriating habit of letting her students make their own mistakes and learn from them, even if the mistake could be lethal.

Because of this, none of Twilight's books had a warning about Poison Joke or how to reverse the effects of its 'curse'.
