It is also an antidote to poisoning by nerve agents. Consumption of this plant produces vivid hallucinations, though it is rarely used as a recreational narcotic. It is one of the most well known members of the nightshade family (Solanaceae). Photographed at the Dilston physic Garden, Northumberland, UK.
