Veith ( 1966 : 3 ) quotes the sinologist Erich Hauer's " opinion that " ma-fei " ( ���l ) means opium . " Victor H . Mair ( 1994 : 689 ) notes that " mafei " " appears to be a transcription of some Indo-European word related to " morphine " . " Although Friedrich Sert�rner first isolated morphine from opium in 1804, Mair suggests, " It is conceivable that some such name as morphine was already in use before as a designation for the anaesthetic properties of this opium derivative or some other naturally occurring substance . " Wang and Ping ( 1999 : 91 ) find consensus among " scientists of later generations " that " mafei " contained " yangjinhua " ( mё�� " " Datura stramonium " " ) and " wutou " ( �p-?" rhizome of " Aconitum ", Chinese monkshood " ) or " caowu " ( I��p " " Aconitum kusnezoffli " n; Kusnezoff monkshood " ).
