one seed, sometimes three seeds. The seed has an outer coat 
which is removed before use. The drug from Jung chou has

ch‘uan], and the seed resembles the soy-bean, whence the above 
names. Let Hrao [5th cent.] says :—[There are three sorts. ] 
One [the seed], which is contracted, small and of a yellow 
colour, is the PS pa, that which is three-edged and black is 
the Hf tou, and that which is small and pointed on both ends is 
called fil] =f kang tsz‘. The pa and the tow can be used in 
medicine, but not the kang tsz‘, which kills man. Lr SHi-omen

male is violent and the female has a slow effect. The capsule 
of the pa tou is like the integument of the ta feng tsz‘' but 
thinner. The kernel within is like the hai sung tsz‘.* The 
capsule cannot be compared to the pai tou k‘ou.—One name 
for the pa tou is EE I F- lao yang tsz*. 
Besides the seeds and the integument, the oil of the 
Seeds and the root are used in medicine.
