Distilled from the plant known as deadly nightshade or belladonna, Atropine contains a poisonous alkaloid similar to aconite. The plant can be recognized by its purple tubular flowers and black berries. While most poisoners use the concentrated form, the berries are sometimes slipped into pies and pastries. The poison’s effects include dry mouth, dilated pupils, a rapid heartbeat, hallucinations, confusion, and possibly seizures.
