Pie lu:—The ti huang grows in the marshes of Hien 
yang [in Shen si, App. 65]. That which is produced ina 
loamy soil is the best. The root is dug up in the 2nd and

this dried state, & Hy 3 kan (dry) t¢ huan, or the fresh 
root is used, AB Hh sheng (fresh) ti huang.

an [the ancient capital of China, in Shen si, App. 6]. The 
tt huang grows in Wei ch‘eng [same as Hien yang, App. 
382]. The fruit looks like a wheat-grain. Now the dried 
ti huang from Peng ch‘eng [in Kiang su, App. 247] is the 
best. That from Li yang [in An hui, App. 186] is of 
second quality. The drug from Pan k‘iao in Kiang ning 
[Nan king, App. 240] is also prized. The juice, pressed 
from the root, is likewise used in medicine,

best drug comes from T‘ung chou [in Shen si, App. 378).

resemble the leaves of the ch‘e ts‘ien [Plantago. See 115] 
and are all on the ground (radical leaves). They are 
wrinkled, rough, and veined. The scapes are from three or four 
inches to one foot high, They bear flowers resembling those 
of the yu ma (Sesamum), of a purple colour. Sometimes 
the flowers are yellow. The fruit is a capsule, like that of 
the lien kiao (Hypericum. See 120]. Small grayish brown 
seeds. The root is like a man’s hand with fingers, varies 
as to size, and is yellow throughout. The plant is not always 
raised from seed, frequently it is propagated from the réot.

becomes very Juicy. The extract obtained by pressing and 
steaming the root is called FA MW TG shu ti huang.
