Su Sune [11th cent.]:—The true si sin from Hua chou 
[in Shen si, App. 85] is slender (fine rootlets) and of a very 
pungent taste, whence the name. It is frequently substituted 
for the tu heng [v. infra}. 
Lit Swi-coen:—The ancient Po wu chi [3rd cent. | 
observes that the si sin is frequently confounded with the 
tu heng. The difference between these two plants is that 
the si stv has tender leaves resembling those of a small _ 
mallow. The stem is slender, the root is straight, of a purple 
colour and very pungent in taste. The tu Jeng has leaves 
resembling a horse’s hoof, a coarser stem, a contorted root 
of a yellowish white colour and a pungent taste.
