Grows in valleys and fields of Jingzhou. Collected on the fifth and fifteenth days of the fifth lunar month are best.
Averse to Magnetitum (Cishi) and wine. In grasslands, exuvies of Hui (viper) and Fu (pit viper) are rarely seen; those that are longer mostly belong to Elaphe carinata (Chi Lianshe) or Peltopelma flavogulare (Huangheshe), whose skins are unrecognizable. What is often obtained now is of this kind, and must be complete. Those from rocks are better; when burned, they treat various severe sores.

Currently, those with red feet mostly come from Jingkou; Changshan, Gaolishan, and Maoshan also have many. Obtained from rotting accumulated grass, avoid injury, and dry in the sun.
People from Huang region roast them over fire until red to pass them off as genuine, which is not authentic. Also known as Ququ. Zhuangzi stated: "Ququ eats snakes." Huainanzi stated: "The flying snake rides the mist but is endangered by Ququ." Its nature can subdue snakes; upon seeing a large snake...
[Note] People in Shandong call the spider "Ququ," which is likely a linguistic error. Zhuangzi's mention of "Ququ eats snakes" and Huainanzi's "flying snake endangered by Ququ" both refer to Wugong (Scolopendra).

Currently, there is a slender yellow insect, resembling Wugong but much longer, commonly called Tucheng (Earth Insect); chickens become intoxicated and even die after eating it. Books say: "The insect with a hundred feet does not stiffen upon death." This insect has many legs; if broken inch by inch, each part moves independently, appearing similar. Physicians no longer use it, and merchants do not value it; it is unclear which is the true specimen.
