〔谨案〕
此物与防葵，都不同类，生处又别。野狼毒今出秦州、成州，秦亭故在二州之界，其太山、汉

元无腹蛇，复云数亩地生，蝮蛇食其根，谬矣。

Some say it only grows in a few mu, and viper eats its roots, making it rare. Tai Shan variety is also used; currently, Hanzhong and Jianping varieties are preferred. It is said to be of the same root type as Fang Kui, but those that sink in water are Ye Lang Du, while those floating are Fang Kui. Rarely used by common people, difficult to obtain, yet an important herb for treating internal abdominal diseases.
[Commentary]
This substance is not of the same category as Fang Kui, nor does it grow in the same places. Ye Lang Du is now produced in Qinzhou and Chengzhou; Qin Ting was originally on the border of these two prefectures. There is no report of production in Tai Shan or Hanzhong. Moreover, Qin and Long are cold regions where vipers do not naturally exist. The claim that it grows in only a few mu and that vipers eat its roots is erroneous.
