[Bencao Yan Yi] Treats chronic Feng Xuan (Wind Tinea), where the whole body turns black, the skin feels stiff like wood, the skin is rough and dry, and there is paralysis in the four limbs. It is suitable to take Wutou Wan (Aconite Pill).
Take one jin of Caowutou (Aconiti Kusnezoffii Radix), place it in a bamboo basket, soak in water, and wash it with a tile inside the basket in the water, similar to the method of cleaning water caltrops. Wait until the outer skin and tips are removed, then drain and let it dry.
Take four liang of Mahua You (Sesame Oil) and four liang of salt, put them in a ding (a type of cauldron), and stir-fry until deep yellow. Pour out the oil, leaving only the salt and Wutou, and stir-fry again until black, stopping when smoke appears. Take one piece of Wutou, split it open; if there is a tiny white spot in the center resembling a grain of rice, it is just right. If there is too much white, continue frying.

Wenyachanglao (Elder Wenya) of Zifu Nunnery in Zhengzhou suffered from this disease. After taking medicine for several years, the black discoloration was completely removed, his leg strength became robust, and his hearing and vision remained unimpaired. A relative of mine suffered from purple macules all over his body, looking like ink. After taking medicine for over a year, his body became smooth and lustrous. I took this medicine for one year, and various wind-induced sores, ulcers, and skin diseases healed. The nature of this medicine is slightly hot. Although it is said to remove toxicity, it is best to drink Wutou Zhou (Aconite Porridge) every five to seven days to harmonize. The method for making porridge is best referenced from Yuzhang Ji.

[Shiyi Fang] For purple macules and white patches: Grind Beimu (Fritillariae Thunbergii Bulbus) into powder. Dip walnut meat into the powder and rub it on the affected area after bathing; this is highly effective. Another prescription: Select high-quality Xinshi (Realgar), grind it extremely fine, mix with true Sesame Oil to form a thin porridge consistency, leave it overnight, and apply the clear oil on top to the affected area until healed. Another prescription: Use Jinshicao (Golden Lion Grass), crush it and rub it on the affected area; this has been repeatedly effective.

[Danzhi] Another prescription:
Du Da Huang (Rhubarb processed with specific methods), Fei Fan (Alumen calcined).
Make these into soap-shaped pills and rub them on the affected area.

Bai Tu (White Baldness):
Songxiang (Processed Pinionis Resina), Wuyi (Chaulmoograe Semen), Huangdan (Mineral Lead Oxide), Guangfen (Kaolin), Kufan (Alumen exsiccatum), Hu Pi (Likely refers to a specific herb, kept as original text "Hu Pi" due to ambiguity, possibly Hu Zhang or similar, but strictly adhering to "keep original name").
Grind all into powder, mix with Sesame Oil and a little Ginger Juice, apply evenly to the affected area.

Another method: Measure the distance between the two nipples using a bamboo strip. Apply moxa moxibustion to the meridian point located at this midpoint. This meridian point is commonly known as "Xia Wa Xue" (Toad Acupoint).
