[Collected Explanations] Su Gong stated: Huangfan (Yellow Alum) is required by alchemists and is also used in leather dyeing.
Li Shizhen stated: Huangfan (Yellow Alum) sourced from Guazhou and Shazhou in Shaanxi, or imported by ship, is of the highest quality. It is yellow in color and resembles Hu Tong Lei (Tamarisk Gum). Some people pick out the yellow pieces from Lvfan (Green Vitriol) to pass them off as genuine, which is not true. The variety from Persia has golden thread-like patterns when broken, called Jin Xian Fan (Gold-line Alum), and can reveal decorative patterns when used to sharpen swords and knives. *Dan Fang Jing Yuan* states: "Wu Se Shan Zhi" (Five-colored Mountain Fat) refers to Wu Huangfan (Wu Yellow Alum).
[Properties and Flavor] Sour, astringent, and salty; toxic.
[Indications] Treats Ding Chuang (furuncles/carbuncles) and promotes flesh regeneration (Su Gong). Treats Ye Ji Zhi (hemorrhoids resembling wild pheasant droppings), E Chuang (malignant sores), Jie Xuan (scabies and tinea) (Li [Shi]). Treats toothache caused by Wind-Heat in the Yangming channel (Li Gao).
[Attached Prescriptions] Five new prescriptions.
Discharge from the ear: Burn two liang of Huangfan (Yellow Alum) until charred, wrap two qian in cotton, and insert into the ear. (*Sheng Hui Fang*)
Frequent recurrence of cheek ulcers in women: Take one and a half liang of Mercury, rub with lard until completely dissolved. Add two liang of powdered Huangfan Shi (Yellow Alum Stone) and one liang of Hu Fen (Lead Carbonate/White Lead). Mix with lard to form a paste. Cleanse the ulcer thoroughly before application. Additionally, apply Hu Fen over the ointment. This is a secret formula from the Gan family. (*Zhou Hou Fang*)
Body scars: Use eight fen each of Huangfan Shi (Yellow Alum Stone, burned until juices are exhausted) and Hu Fen (White Lead, stir-fried until yellow). Grind finely, mix with lard rendered in the twelfth lunar month to form a paste. Rub the affected area with raw cloth until painful, then apply the medicine five times. Take equal parts of Eagle Droppings and grass from White Swallow Nests (burned to ash), mix with human milk, and apply. The scars will naturally disappear, and the skin will return to its original smooth state. (Cui Yuanliang, *Hai Shang Ji Yan Fang*)
Acute Gan erosion of teeth: Take half a qian of Huangfan (Yellow Alum) and Qingfan (Green Vitriol), one qian of Bai Fan (White Alum, burned), and one fen of She Xiang (Musk). Grind into powder. Apply externally; it induces salivation. (*Sheng Hui Fang*)
Du Jing Yin Chuang (Ulcers due to jealousy-induced sexual frustration): Take equal parts of Huangfan (Yellow Alum), Qingfan (Green Vitriol), and She Xiang (Musk). Grind into powder and apply externally. No more than three applications are needed. (*Qian Jin Fang*)
[Collected Explanations] Li Shizhen stated: This is the water alkali precipitated and condensed inside boiling water kettles, resembling fine sand.
[Indications] Stops Xiao Ke (wasting-thirst syndrome). Take one liang, grind into powder, and make pills the size of wutong seeds using rice from millet. Take twenty pills with Ginseng decoction. Additionally, for pediatric oral thrush, mix the powder with vinegar and draw a cross on the soles of both feet before sleep; this is effective (Li Shizhen).
[Attached Prescriptions] Two new prescriptions.
Wasting-thirst with excessive thirst: Take equal parts of Tang Ping Nei Jian (Water Kettle Alkali), Ge Gen (Pueraria Root), and Shui Ping (Water Fern, dried). Take five qian per dose, decoct in water, and drink. Another prescription: Take one liang each of Tang Ping Nei Jian (Water Kettle Alkali) and Ba Qian Gen (Smilax Root, stir-fried), and two liang of Wu Mei (Dark Plum, with seeds, dried). Grind into powder. Take two qian per dose, decoct in one cup of water in a stone vessel until reduced to seventy percent, and sip warm once daily. (*Sheng Ji Lu*)
