Taste pungent. Nature warm. Non-poisonous. 
The su is mentioned in the Rh ya [64]. 
T‘ao Huna-King :—The sw has its leaves purple under- 
neath, They are very fragrant. Another sort, the leaves 
of which are not purple coloured, and which resembles the 
jen, is called BF Bk ye (wild) su. It is not much used. The 
same author says, in another work quoted in the Ry ya t:— 
The #€ jen resembles the su, but it grows higher, is white 
(downy, not purple-coloured leaves), and not very fragrant. 
The seeds are oily, and by pressure oil is obtained from 
them. In Kiang tung [An hui, App. 124] the people call it 
FA yi. 
Su Sune [11th cent.]:—The su is the 3% i ¢s2* (purple) 
su. The best sort has the leaves purple coloured on both 
sides. The stem and the leaves are gathered in summer, 
the seeds in autumn. ‘There are several kinds of su, the 
shui (water) su (see 68], the yd (fish) su, ete. All these are 
kinds of jen [v. supra].
