[Names] Fu Zhong Mo (from *Sisheng Bencao*), Dang Mo (from *Kaibao Bencao*), Fu Mei (from *Bencao Gangmu*), Fu [Character missing in source, likely referring to a specific type of soot], Gu Di Mo.
Li Shizhen stated: Large vessels are called fu or guo; small ones are called dang.
[Properties and Flavor] Pungent, warm, non-toxic.
[Indications] Treats zhong e (sudden attack by evil pathogens) and gu du (poisoning from gu worms), hematemesis (vomiting blood), and xue yun (syncope due to blood stasis or qi rebellion). Take two qian with wine or warm water. It can also be applied externally to jin chuang (traumatic wounds caused by metal weapons) to stop bleeding and promote tissue regeneration (from *Kaibao Bencao*).
Resolves food stagnation, treats tongue swelling, hou bi (obstruction and pain in the throat), mouth ulcers, and yang du fa kuang (mania caused by yang toxicity) (added by Li Shizhen).
[Elucidation] Su Song said: In ancient prescriptions for treating shang han (cold damage), the "Hei Nu Wan" (Black Slave Pill) uses fu di mo (soot from the bottom of the pot), zao tu mo (soot from the chimney flue), and liang shang chen (dust from the beams) combined with other herbs, because their therapeutic effects are similar.
[Attached Prescriptions] Seven old prescriptions, six new prescriptions.
Sudden heart qi pain: Two qian of dang mo, mixed and taken with hot urine (from *Qianjin Fang*).
Zhong e causing heart pain: Five qian of dang mo, one qian of salt. Grind uniformly, mix with one cup of hot water, and take orally (from *Qianjin Fang*).
Muscle spasms extending into the abdomen: Powder from fu di mo, taken with wine, one qian (from *Zhouhou Fang*).
Huo luan (cholera-like syndrome) with vomiting and diarrhea: Half a qian of gu di mo (pot bottom soot), half a qian of mo from the stove front. Mix with one cup of boiling water, stir vigorously thousands of times, cover with a bowl, and drink through the mouth. One or two mouthfuls will stop it immediately (from *Jingyan Fang*).
Hematemesis and hemoptysis: Stir-fry gu di mo, grind finely, take two qian with jing hua shui (first drawn well water at dawn). Continue for three doses (from *Jiji Fang*).
Breech presentation in women: Use the middle finger to apply soot from under the pot, drawing crossing lines on the infant's feet, which ensures normal delivery (from *Qianjin Fang*).
Postpartum blood retention: Take two qian of hot wine infused with soot smoke from the pot bottom (from *Shengsheng Bian*).
Sudden massive tongue swelling: Swollen like a pig bladder, filling the mouth, fatal if untreated. Apply fu mo mixed with wine topically (from *Qianjin Fang*).

Nasal polyps: Same prescription as above, cured in three to five days (from *Puji Fang*).

Hand eczema/scratches swollen and suppurating: Grind gu qi mo (soot from the pot center) finely, mix with refined sesame oil, and apply topically (from *Jianbian Fang*).
