Final answer:
Deadly nightshade is falsely stated to be the common name for bufotenin; in fact, deadly nightshade refers to the belladonna plant containing toxic compounds like atropine and scopolamine, while bufotenin is a substance found in mushrooms.
Step-by-step explanation:
The statement that deadly nightshade is the common name for bufotenin is false. Deadly nightshade, also known as belladonna, is a plant from the genus Atropa. The plant contains anticholinergic compounds like atropine and scopolamine, which are toxic and can be fatal when ingested. These compounds were historically used to dilate pupils cosmetically, but due to their toxic nature, this practice has been discontinued. Bufotenin, on the other hand, is a different substance entirely, which is found in some species of mushrooms and is not associated with the belladonna plant.
