l8 CHINESE MATERIA MEDICA. 



drugs resemble each other a good deal, but the one under 

 consideration is much larger and darker, and marked ex- 

 ternally with dark patches of the dried juice. It has a sweet, 

 mucilagenous taste, and is used as a tonic like ginseng. It is 

 used in syphilis, just as the Campanula glaiica is amongst the 

 Japanese." Ch 'nan-tang (/![ ^) is from Szechuan, and is in 

 large dark pieces, resembling Sha-shen (^ ^); Hsi-tang 

 (H ^.) is from Shensi, Lu-tang (^{^ ^) from Luan prefecture 

 in Shausi. Pao-tang (-gj ^) is the drug in bales, Hsiang- 

 tang (^ ;^i is that in boxes, while Feng-p'i (H, ^), or Feng- 

 p'i-tang (HI, ^ ^), or Hung-tang (ifl %) is the substance in 

 bundles fastened with red cord. Tatarinov thought to identify 

 Tang-shen (^^ i^) as a Convolvulus^ but there is no doubt that 

 this is a campanulaceous plant. 



Chieh-keng k\% ^), Platycodon grandifiorum^ is a red 

 stemmed genus of the Campamilacecs. The Pentsao savs that 

 it is like the Chi-ni (^^), the latter being sweet, while the 

 former is bitter. Like others of this order, its roots are used 

 to falsify ginseng. It is brought from Szechuan, Hupeh, 

 Honan, Shansi, and possibly from other provinces of North 

 China. It occurs in short, dark-brown pieces, much shriveled 

 and wrinkled, and sometimes moniliform, varying in size from 

 that of a little finger to a writing quill, or even smaller. Its 

 taste is said to be slightly bitter and demulcent. Its ascribed 

 medicinal qualities are many, among which the more important 

 are tonic, astringent, sedative, stomachic, and vermifuge. It 

 is specially recommended in bloody fluxes from the bowels. 



ADIANTUM. — The substance spoken of in the Customs 

 Lists as T'ieh-sien-ts'ao (||j H :^), 1281, is given in the List 

 of Chinese Plants known to Linnaeus as Adiantuni fiabellatum^ 

 and is also included in Loureiro's Flora Cochinchinensis under 

 the same classification. T'ieh-sien-ts'ao 1^ |f^ i^ ), as given 

 in the Pentsao^ seems rather to be a Polygonum^ and is repre- 

 sented to be the same as Pien-hsli {% H), Polygonum avicu- 

 lare. The part used is the root, while the product appearing 

 at the Customs is the stalk and leaves. Further identification 

 of this substance is necessary. The drug spoken of in the 

 Pentsao is used in the treatment of colds.
