MATERIA MEDICA OF THE ANCIENT CHINESE. 139 
Pie lu:—Other names: $f Hi Me tsu, FE EL Me tsi. 
The shw’ su grows in Kiu chen [App. 154], in ponds and 
marshes. It is gathered in the 7th month. 
Wu P‘u [38rd cent.] calls it SE BE &é su (chicken sw). 
Tao Hune-xine :—It is not used in medical prescrip- 
tions, Kiu chen is a distant place which has not been 
identified, 
Su Kune [7th cent.]:—This kind of su grows in 
marshes and by the sides of water-courses. It resembles the 
sian fu (Inula. See 81]. The leaves stand in twos opposite 
and are very fragrant. In Ts‘ing, Ts‘i [both in Shan tung, 
App. 363, 348], and in Ho kien [in Chi li, App. 75] the 
people call this plant shud su [as above], in Kiang tso 
[S. An hui, App. 124] it is known by the name # BE ts 
ning, in Wu Hui [in Kiang su, Che kiang, App. 391] it is 
called ki su [as above]. 
Han Pao Sueve [10th cent.]:—Leaves like those of 
the pai wei [ Vincetoxtcum. See 44], in twos opposite. Violet 
flowers coming out between the joints. Taste pungent, 
aromatic, 
Su Sune [11th cent.]:—The shuz su is a common plant 
by the sides of water-courses. It is much eaten in the 
South as a vegetable. It is also frequent north of the Kiang, 
but the people there do not eat it. In Kiang tso [v. supra] 
ki su is not the same as the shui su. The tsi ning 
[v. supra] is also a different plant. The leaves of the shu a 
are toothed, fragrant, of a pungent taste, those of the ts? ning 
are narrow and longer, covered with hair, and exhale an 
unpleasant odour. 
Wu Saut [Mongol period] says that the shui su is also 
‘called BG BS 28 Fi Jung nao po ho (Camphor mint), but 
from an earlier account, quoted by Su Suna, it would seem 
that this plant resembles an Artemisia,
