Generally, things that move swiftly are wind and snakes. Centipedes can subdue snakes, thus they can also quell wind. It is a herb of the Jueyin meridian, so its indications mostly belong to the Jueyin pattern. When using it, select those that are flat and long, with black heads and red feet as superior. The thousand-legged worm resembles the centipede but has white flesh on its head, and both its face and mouth are pointed. If mistakenly used and its foul odor enters the brain, it can cause death; one must be cautious and choose carefully.

(For medicinal use, after calcination, soak in water; those that condense into white crystals are best. Alternatively, heat until red in fire, quench seven times in wine, grind finely, process by levigation, and dry in the sun. Some methods involve soaking in distilled spirits, combining with Camphor (Zhang Nao), and sublimating in a jar to collect the powder.)
