For *gan* diarrhea: Use *Chishizhi* (Halloysitum Rubrum) powder, mixed with rice drink, take half a qian.

For brain *gan* (head *gan*) with itchy eyebrows, hair forming tufts, yellow sallow complexion, and emaciation: Instill gallbladder juice from a crucian carp (*Jiyu*) into the nose. Effective within three to five days.

For *Zouma Gan* (rapidly progressing necrotizing stomatitis): Burn silkworm pupal skin (*Cantui Zhi*) until carbonized but retaining its nature, add a small amount of *Shexiang* (Moschus), grind into powder, mix with honey, and apply externally. Adding a small amount of *Kufan* (Alumen) is especially good.

A case: A fourteen-year-old son of a wealthy family had a yellow sallow complexion, strong appetite, easy hunger, refused to eat without meat, and suffered from diarrhea for one month. His pulse was large in both hands, yet he did not feel fatigued. Typically, damp-heat causes fatigue and poor appetite; here, he was emaciated but ate much, and was not thirsty. This indicated parasitic dysentery. Examination of stool confirmed roundworms (*Huichong*). I instructed him to use vermifuge drugs rather than digestive resolving drugs, and he recovered.

The following year, during the transition between spring and summer, he experienced diarrhea without abdominal pain and dry mouth. This was because last year only the worms were treated, not the *gan* heat. Thus, I prescribed a formula to clear *gan* heat. He took concentrated *Baizhu* decoction for three days, after which the diarrhea stopped by half. Seeing that he was very emaciated, I advised using *Baizhu* as the sovereign herb, *Shaoyao* (Paeoniae Radix Alba) as the minister herb, combined with *Chuanxiong* (Ligustici Chuanxiong Rhizoma), *Chenpi* (Citri Reticulatae Pericarpium), *Huanglian* (Coptidis Rhizoma), *Huhuanglian* (Scutellariae Barbatae Herba), and a small amount of *Lushen* (Aloe) to form pills. These were taken with *Baizhu* decoction. He was forbidden from eating meat and sweet foods. He would naturally recover after three years.
