Comp. Rh ya, 142, for other ancient names. 
Pen king :—Tsz‘ ts‘ao (purple herb). The root is 
officinal. Taste bitter. Nature cold. Non-poisonous. 
Pie lu:—The tsz‘ ts‘ao is also called 3% Ff tse‘ tan 
(purple cinnabar red). It grows in the mountain valleys of 
Tang shan [in Kiang su, App. 334] and in the country of 
Ch‘u [Hu kuang, App. 24]. The root is dug up in the 
3rd month and dried in the shade. 
In the Wu P‘u [8rd cent.] it is called Hi WL (2 hae 
(earth blood). This name is properly applied to Mulia. 
[See 182.] 
T‘ao Hune-Krive :—This plant is produced in Siang yang 
Lin Hu pei, App. 306]. Much of the drug is also brought 
from the district of Sin ye in the Nan yang prefecture 
[in S.W. Ho nan, App. 312, 231]. The people there 
cultivate it and employ it for dyeing a purple colour. It is 
not much used in medicine. 
Lat Sut-curn :—This plant has purple flowers and a 
purple root, whence the name tsz‘ ts‘ao. It is cultivated for 
the colour yielded by its root. This root must be dug up 
in spring before the plant has flowered. Then the colouring 
matter will be found to be very bright. But if gathered 
atter flowering the colour has- become deeper and is conse- 
quently inferior in quality. The top of the root [I shouid 
rather think the plant above the ground] is covered with 
white hair, By certain processes a yellow colour can be 
produced from the root. The Yao chuang people [v. App. 
402] call this plant ff tf BE ya hien ts‘ao.
