チョウセンアサガオ
"Datura" Linnaeus...The important narcotic species of the Old World is "Datura metel". Early Sanskrit and Chinese writings report a hallucinogen that has been identified with this species, and it was probably "D. metel" that the Arabian Avicenna mentioned as a drug called "jouz-mathel" in the eleventh century...The epithet "Datura" was taken by Linnaeus from the vernacular name "dhatura" or "dutra" in India, where knowledge of the intoxicating effects of the plant go back to prehistory...This species, of which there are several rather distinctive types, is indigenous to Asia but now ranges widely in tropical and subtropical Asia, Africa and America.
