146 CHINESE MATERIA MEDICA. 



terms refers to the Datura stramonium, Hoffman and Scliultes 

 have assumed f^ jja !§i (Fo-ch'ieh-erh) as the name of this 

 last, but such a name has not been found in Chinese books, 

 does not seem to be known in Japan, and is probably a 

 mistake for Fcng-cW'ieh-erh. In the Customs List the first 

 character of this last term is wrongly written ^ (Feng), 302, 

 and the drug is considered to be identical with j^^j ^. 1^ (Nao- 

 yang-hua), 894, which is there identified as Datiira alba. 

 Without doubt this last term is sometimes referred to Datura 

 metel,, but it also refers to Hyoscyamzis niger (which see), and 

 it is discussed in the Pentsao under the article ^ Si5 E^ (Yang- 

 chih-chu), which certainly is Rhododeiidro7i {Azalea) sinense 

 (which see). The ericaceous and solanaceous plants seem in 

 some cases to be nearly related in the physiological action 

 of their active principles, as well as being similar in external 

 appearance. Hence the ease with which they have been con- 

 founded by the Chinese. 



The flowers and seeds of the Man-t^o-lo are used in 

 medicine as a wash for eruptions on the face, oedema of the 

 feet, and prolapsus of the rectum. They are prescribed also 

 for colds, chorea, and nervous disorders, and their use as an 

 anaesthetic is also mentioned. Their delirient action is also 

 spoken of, being said to produce laughter or dancing move- 

 ments (1^). If equal quantities of this and of Cannabis 

 saliva are gathered in the seventh and eighth moons, dried 

 in the shade, pulverized, and digested in wine, the prepara- 

 tion, when ingested, will produce a narcotic anaesthesia that 

 will enable small operations and cauterizations to be done 

 without pain. 



DATURA METEL.— I^J ^ 1^ (Nao-yang-hua), 894. 

 This species of Datura is included in Burnett's list of the Flora 

 of China, and this name is assigned to it by Dr. Bridgeman 

 in his Chinese Chrestomathy. Parker makes it identical with 

 Datura alba. Tatarinov calls it Hyoscyamus. Hanbury says 

 "flowers of Rhodode^idi-onl'''* As this Chinese term is in- 

 cluded in the Pentsao as a synonym of ^ ^ f^ (Yang-chih- 

 chu), discussion of its medicinal uses will be referred to that 

 article (see Rhododendro/i sinense).
