[Processing Methods]
Remove the outer skin and umbilicus, soak in hot water for use; or wrap in wet paper and bake in sugar. *Xueqi* (Herba Descurainiae) is used as a guiding drug; it is incompatible with *Mangcao* (Radix Aconiti).
[Properties, Flavors, Meridian Tropism, and Efficacy]
Pungent, bitter, greatly warm, toxic. Enters the Liver, Spleen, and Kidney meridians. Treats numbness and paralysis caused by Wind-Stroke; eliminates phlegm-saliva during Wind-Epilepsy attacks. Reduces carbuncles and swellings, dissipates blood stasis, breaks down hard accumulations, and can induce abortion (contraindicated in pregnancy). Treats blood stasis from metal wounds and fractures; eliminates disorders such as trismus (lockjaw) and facial deviation. When combined with *Fangfeng* (Radix Saposhnikoviae), it does not cause numbness; when combined with ox bile, it is not drying; when processed with fire, its toxicity is reduced. Mix ox bile evenly into Arisaema, hang in a ventilated place to dry, which becomes Danxing (Gallbladder Arisaema).
[Origin and Morphology]
Produced in Hanzhong and Yuanju regions. Roots are harvested in the second and eighth lunar months. Currently, they are also found in various prefectures of Hebei Province. Newly grown roots are bean-sized, gradually enlarging to resemble Banxia (Rhizoma Pinelliae) but flatter. Older roots are round, about one cun in diameter, with large ones the size of a chicken egg, surrounded by round buds. Seedlings emerge in the fourth month, growing over one chi tall. The single stem bears leaves like claws; a cluster produces seven or eight stems, occasionally sending out one stem to form a spike.
[Formulas and Applications]
For all metal wounds and fractures, combine with Fangfeng, grind into powder, apply externally or take internally. (Verified Formula 1.)
For Tetanus and Wind-Stroke. Use the same method. (Formula 2.)

For infantile oral thrush (white patches like goose mouth): Grind into powder, mix with vinegar, apply to the sole of the foot, left for males and right for females. (Formula 17.)
For Gangrenous stomatitis penetrating bone and cheek. Hollow out the center of raw Nanxing (Rhizoma Arisaematis), insert a piece of Xionghuang (Realgar), wrap in dough, and roast. Wait until Realgar melts into liquid, cover with a cup to seal, remove fire toxicity, grind into powder, add a small amount of Shexiang (Moschus), and sweep onto the wound. It heals in a few days. (Formula 18.)
