【炮制方法】
去除外皮和脐部，用热水浸泡后使用；或者用湿润的纸包裹，在糖中煨烤后使用。以蜀漆作为引经药，畏忌莽草。
【性味归经与功效】
味辛、苦，性大温，有毒。入肝、脾、肾三经。治疗中风引起的肢体麻木不仁，祛除风痫发作时的痰涎。消除痈肿并消散瘀血，攻逐坚积并可导致堕胎（孕妇慎用）。治疗金创骨折后的瘀血，祛除口噤不开、口眼歪斜的疾病。与防风同用则不致麻木，与牛胆同用则不致燥烈，与火炮同用则毒性降低。将牛胆汁混合均匀纳入天南星中，悬挂在通风处晾干，即为胆南星。

[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 various cases of trismus, combine with Shengjiang (Rhizoma Zingiberis Recens) and Ziye (Folium Perillae), add a small amount of ox bile, decoct in water, and take orally. (Formula 3.)
For trismus: Roast one piece until done, wrap diagonally in paper, cut small holes for ventilation to allow medicinal qi to enter the mouth, and the jaw will naturally open. (Formula 4.)
For infantile convulsions: Combine with Chencha powder (Cinnabar powder), administer with Jingjie decoction (Decoction of Herba Schizonepetae). (Formula 5.)
For Wind-Epilepsy with phlegm confusing the mind: Make pills with Ginger juice, administer with Ginseng decoction. (Formula 6.)
For infants who cannot speak after epilepsy: Grind into powder, mix and take with Pig Gallbladder juice. (Formula 7.)
For facial deviation: Grind into powder, mix with Ginger juice, and apply topically. Apply to the right side if the face deviates to the left, and to the left side if it deviates to the right. (Formula 8.)
For women suffering from eye pain due to Wind-Phlegm attacking the eyes: Process Nanxing (Rhizoma Arisaematis) with vinegar, grind into powder, and take with wine. (Formula 9.)
For Wind-Phlegm headache: Combine with Jingjie leaves, make pills with Ginger juice, and take orally. (Formula 10.)
For dizziness, vertigo, and vomiting: Combine with Banxia (Rhizoma Pinelliae) and Tianma (Rhizoma Gastrodiae), double the amount of white flour, make water pills the size of beans, take thirty pills each time, and boil the pills before consumption. (Formula 11.)
For early-stage Wind-Stroke or Qi obstruction: Add a small amount of Muxiang (Radix Aucklandiae), decoct in water with ginger, and take orally. (Formula 12.)
For right arm pain due to Phlegm-Dampness: Combine with Shengjiang (Rhizoma Zingiberis Recens) and Cangzhu (Rhizoma Atractylodis), make pills, and take orally. (Formula 13.)
For Qi-Phlegm cough: Combine with Banxia (Rhizoma Pinelliae) and Chenpi (Pericarpium Citri Reticulatae), make pills with water and ginger. Suitable for those with a surging pulse at the Cun position. (Formula 14.)
For temporomandibular joint dislocation: Grind into powder, mix with Ginger juice, apply to both cheeks, and reduce after one night. (Formula 15.)
For infantile delayed closure of fontanelle (Jielu): Grind into powder, mix with light vinegar, apply on cloth to the fontanelle, and iron with heated hands for immediate effect. (Formula 16.)
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.)
