The Black Henbane is another hyoscyamine, hyoscine, and atropine bearing plant. It mention was more for folkloric significance, and ingestion almost always leads to something bad "Algo Mal". Although it has narcotic properties Ingestion of datura would most likely lead to injury either from the poisoning or the unpredictable state it could induce. There is a alkaloid found in the green parts potatoes (the potato is a member of the solonaceae familiy) that is a gastrointestional poison. I myself once ingested some raw green potato and got very sick the following day with gastrointestional disturbances.
