I guess I'll go over some of the poisonous plants we have here in the US. DON'T EAT ANY OF THESE. Several are deadly poisonous. -Death Carnas/Camas (Deadly poisonous) Don't confuse these with wild garlic or onions. Very Deadly Thorn Apples/Crimson Weed (Deadly poisonous) Everyone has seen them, and be glad you haven't eaten one, otherwise you would probably be dead. All parts are deadly. Its also said these nasty plants mess your brain up if you live through eating it.
