<human>:  Are there any common roots around the midwest that are poisonous to humans? Maybe lethally?
<bot>: That’s an interesting question. The “roots” of plants can vary a lot in terms of taste, but they are often full of strong poison compounds. Many roots will contain chemicals that are toxic to humans, so for that reason we shouldn’t eat any roots, and we’d never eat something from the ground without first washing it. I don’t know about fatal poison, but I’d guess there might be something in the desert regions that you should be wary of.
