When an anal fistula (anal ulcer forming a tract) has formed into a tract, surgical excision is difficult to achieve completely, and the traditional thread-ligation method (Guaxian Fa) may not be effective. The two prescriptions by Mr. Zhu are simple and extremely effective, yet unknown to the general public.

Take the tip of a gecko's tail (Bihu Wei), cut a segment according to the size of the tract, insert it into the tract; this extracts pus and promotes wound closure with extreme speed. Use earthworms (Wuguchong, specifically *Sarcotragus* or similar ground beetles used in TCM) with tails, rinse clean, dry-roast over gentle fire until the medicinal properties are preserved, mix with refined wheat flour to form strips; using these is also excellent.

For treating chronic ulcers that have persisted for years, there is a miraculous effect.
Ingredients: Ash from paper incense sticks (Zhiding Hui, sifted to be extremely fine), Dongdan (Red Lead Oxide), Borneol (Bingpian), Lard (Zhubanyou).
Preparation and Application: Pound uniformly, spread on a patch, and apply to the lesion.

For treating scabies (Jiechuang) and eczema (Shichuang), it provides rapid relief from itching.
Preparation: Put clear sulfur (Mingjing Suhuang) into an iron pot, melt over low heat, pour into brine to solidify, remove, melt again, and quench again. Repeat this dozens of times until the sulfur turns deep purple. Grind this single ingredient into a fine powder, boil chicken egg yolk (Jizihuang) to extract oil, and use the oil to mix and apply the powder. First, wash the area clean, pat dry, apply the medicine, wash once daily, and reapply.

Once external sores (Waiyang) have ulcerated and pus exudes, washing them clean must be the primary principle. Only then can bacteria be eliminated, allowing new tissue to grow and the wound to close; otherwise, if foul necrotic tissue is not removed, the condition will inevitably spread. Moreover, the sticky toxic fluid from wet, itchy, and malignant sores easily spreads四处, and can certainly infect others, causing severe harm. There are many ancient washing prescriptions. For Yang syndromes (Yangzheng), herbs that clear heat, dry dampness, and detoxify are used; for Yin syndromes (Yinzheng), herbs that promote Qi circulation, invigorate blood, and nourish are used. The various prescriptions recorded in *Yizong Jinjian · Waike Xinfa* are already perfect and inexhaustible in their utility. However, with the recent rise of Western medicine, treating sores emphasizes antiseptic disinfection most heavily. In the aspect of washing, this is where the focus lies: it can remove necrosis and generate new tissue. The medication is extremely simple yet orderly, appearing more convenient and practical than our country's old methods, while being definitely effective. But the formulas are potent; success depends entirely on judging the severity and dosage precisely. Excessive use brings no benefit but causes harm. Here, I briefly record some points as a reference for using Western medicines.

"Carbolic acid" (Jiaponi) is the transliteration of the Western term. The Japanese call it Shitan Suan (Coal Acid); "Shitan" means coal, and "Suan" refers to the essence/concentrated part in Chinese. The drug is ice-like in crystal form, melting into oil at high temperatures. Dissolving it in water: one part ice melts into nine parts water to become an oily substance; dissolving further, twelve parts water can dissolve one part oil into a water solution. However, this is still the raw material. When washing ulcers, this solution must be diluted with fifty times its volume in clear water. It can wash away necrotic ulcers, completely removing foul decay without injuring healthy flesh or causing severe pain. Must gently wash with absorbent cotton gauze, blot dry the pus, and then apply ointment. For itchy sores, wet scabies, urticaria (Youfeng), eczema (Shizhu), and severe wet itching, thirty times dilution with clear water can be used, but not too concentrated. If less than thirty times dilution, it causes severe pain. If the major syndrome has little pus left and necrotic tissue is clean, then 100-times or 80-times dilution is appropriate. If itchy sores exude fluid, form crusts in patches, and adhere tightly, soak absorbent cotton gauze in the 30-times diluted medicinal water, apply wet to the sore for one or two quarters of an hour (15-30 minutes); the hard crust will float up, then wash gently. Once new muscle/tissue gradually fills the wound and pus is exhausted, this medicine should no longer be used; washing with boric acid water is better. Whenever using this water to wash sores, do so once a day, not more frequently.
