Treatment for white patches (Bai Bo) on the neck, nape, and head/face, which spread gradually like tinea but without ulceration.
Apply the fat from dried eel to the affected area. First, wash and wipe the white patches, then pat or scrape them with the hand until they feel rough and painful and become dry. Subsequently, apply the eel fat. One application leads to cure; difficult cases require no more than three applications. (From *Waitai Miyao*, Vol. 15)
Another prescription:
Take shed snake skin, cook it thoroughly, and rub it over the affected area hundreds of times. Discard the skin in the grass. (From *Waitai Miyao*, Vol. 15)
Prescription for treating white patches on the body.
Use rainwater collected from hollows in trees to wash the affected area. Crush cinnamon bark (*Cinnamomi Cortex*), mix it with saliva, and apply the paste to the white patches three times daily. (From *Waitai Miyao*, Vol. 15)
Prescription for treating white alopecia (Bai Tu).
Prepare mutton similar to jerky, roast it until fragrant, and while hot, compress it onto the affected area. No more than three to five applications are needed for recovery. (From *Waitai Miyao*, Vol. 32)
Another prescription:
First, wash the area with a hot decoction of soap pod (*Gleditsiae Fructus*), dry it, and apply a small amount of sesame oil (*Sesami Oleum*). Repeat several times until cured. (From *Zhouhou Beiji Fang*, Vol. 5)
Another prescription:
Take soybean (*Sojae Semen Preparatum*) and human skull bone (*Ossis Crani Humani*) in equal parts. Calcine both into powder, mix them, and combine with lard rendered in the twelfth lunar month to form a mud-like paste. Apply to the affected area for immediate cure. (From *Waitai Miyao*, Vol. 32)
Prescription for removing verrucae vulgaris (Yuan Mu).
On the seventh day of the seventh lunar month, take one he of soybeans (*Sojae Semen*). Rub the verruca three times with the beans. Have the patient plant the bean in the second position at the east end of a south-facing house. When the bean sprouts four leaves, pour boiling water over it to kill it; the verruca will then fall off. (From *Waitai Miyao*, Vol. 29)
Another prescription:
Mix pine resin (*Pini Resina*) and cypress resin (*Cupressi Resina*) and apply it to the verruca. After one night, the location of the verruca will be unnoticeable. (From *Waitai Miyao*, Vol. 29)
Another prescription:
Make moxa cones (*Artemisiae Argyi Folium*) and place them on the verruca for moxibustion. Three cones are sufficient for removal. (From *Waitai Miyao*, Vol. 29)
Another prescription:
Rub realgar sulfur (*Realgar* or *Stibnite* contextually often refers to Shi Liu Huang - Realgar/Orpiment mix or specifically Realgar in some contexts, but strictly Shi Liu Huang is Realgar/Orpiment or sometimes misused for Sulfur mineral. WHO standard for Shi Liu Huang is Realgar. However, in external use for warts, it might refer to native sulfur. Given "Shi Liu Huang", WHO term is Realgar. But historically for warts, native sulfur was common. I will stick to WHO term for the Chinese name provided: Realgar.) rub the verruca six to seven times for removal. (From *Waitai Miyao*, Vol. 29)
Prescription for removing melanotic spots (Hei Zi) and skin tags.
Calcined Rhizoma Veratri Albi (*Veratri Radix et Rhizoma*) ash (5 sheng), Calcined Ginger (*Zingiberis Rhizoma Recens*) ash (5 sheng), Calcined Alum (*Alumen*) (2.5 sheng).
Mix the above three ingredients evenly. Steam until vapor penetrates thoroughly. Collect one dou of liquid from the bottom of the steamer. Filter the juice and boil it in an iron vessel until reduced by half. Continue boiling with high heat while stirring with a chicken feather until the medicine naturally breaks (indicating proper concentration). To remove melanotic spots and skin tags, first slightly injure the epidermis just enough to break the skin, then apply the medicine as a spot treatment. This formula is named "San Hui Jian" (Three Ash Decoction).
