【方歌】狐尿刺生手足间，闷肿焮痛红紫斑，螳螂精尿流积毒，
误触肌肤痛不眠。
【注】此证《大成》书名狐狸刺，《外台》、《总录》二书名
狐尿刺。由螳螂盛暑交媾，精汁染于诸物，干久有毒，
人手足误触之，则成此患。初起红紫斑点，肌肤干燥，
闷肿焮痛，不眠，十日后腐开，疮口日宽。内宜服黄连
解毒汤，外以蒲公英连根浓煎温洗，若得鲜蒲公英，捣
汁涂患处更佳。盖螳螂又名野狐鼻涕，此证取名，盖本
于此。将溃治法，按痈疽肿疡门。
方剂：黄连解毒汤（见部黑疔）

故掌心燥痒起皮，甚则枯裂微痛者，名掌心风。由脾胃

【方歌】狐尿刺生于手足之间，局部肿胀灼痛，伴有红紫色斑片。这是螳螂在盛夏交配时，其精液沾染在物体上，干燥后产生毒性，人手或脚误触所致，会导致肌肤疼痛难忍、无法入睡。
【注】此病症在《外科大成》中称为“狐狸刺”，在《外台秘要》和《医宗必读·总录》中称为“狐尿刺”。这是由于螳螂在盛夏时节交配，精汁沾染在各种物体上，日久干燥后具有毒性，人的手或脚误触之后，便形成此病。初起时出现红紫色斑点，肌肤干燥，感觉闷胀、肿胀且灼热疼痛，导致失眠；十日后疮口溃烂腐坏，疮口每日扩大。内服宜用黄连解毒汤，外用蒲公英连根浓煎，趁温热清洗患处；若能获得新鲜蒲公英，捣碎取汁涂抹患处效果更佳。盖因螳螂又名“野狐鼻涕”，此病取名大概源于此说法。对于即将溃破时的治法，参照痈疽肿疡门的处理方法。
方剂：黄连解毒汤（见部黑疔章节）
【方歌】鹅掌风生于掌心部位，皮肤干燥开裂，呈现紫白相间的斑块。这是由杨梅疮余毒未尽，兼有血燥，又感受风毒，凝滞而成。
【注】此病生于掌心，是由于患过杨梅疮后余毒未清，加之血虚生燥，再受风毒侵袭，凝滞而发病。初起时出现紫白斑点，层层叠起白色皮屑，质地坚硬且厚，干枯枯燥并开裂，蔓延至整只手。外用二矾散清洗，三油膏擦拭，内服祛风地黄丸的方料，加入土茯苓、白鲜皮、当归作为佐使药，制成丸剂服用效果显著。若病程长久演变为癣症，则难以治愈。又有并非因杨梅疮后遗症，无故出现掌心干燥瘙痒、脱皮，甚至干枯开裂伴轻微疼痛者，名为“掌心风”。这是由于脾胃有热，血燥生风，血液不能濡养皮肤所致。宜服用祛风地黄丸，外用润肌膏，长期涂抹即可痊愈。

[Prescription Verse] Hu Niao Ci (Fox Urine Thorn) arises between the hands and feet, presenting with stifling swelling, burning pain, and red-purple macules. This condition is caused by the accumulation of toxic fluids from mantises mating in midsummer; if human skin on the hands or feet accidentally touches these dried secretions, it causes severe pain that prevents sleep.
[Annotation] This condition is named "Hu Li Ci" (Fox Thorn) in *Waike Dacheng* (Comprehensive Book of External Medicine), and "Hu Niao Ci" (Fox Urine Thorn) in *Waitai Miyao* (Essential Prescriptions from the Imperial Library) and *Zonglu*. It occurs when mantises mate during the hot summer, their seminal fluid staining various objects; after drying for a long time, it becomes toxic. If people's hands or feet accidentally touch it, this affliction develops. Initially, red-purple spots appear, the skin is dry, accompanied by a sensation of stifling fullness, swelling, and burning pain, leading to insomnia. After ten days, the tissue necrotoses and opens up, with the wound widening daily. Internally, one should take Huanglian Jiedu Tang (Coptis Decoction to Relieve Toxicity). Externally, boil fresh Dandelion roots (including the root) thickly and wash the area while warm. If fresh Dandelion is available, crushing it to extract juice and applying it to the affected area is even better. The name likely derives from the fact that mantises are also known as "Wild Fox Nasal Discharge." For treatment methods when the abscess is about to ulcerate, refer to the section on Carbuncles and Ulcers.
Formula: Huanglian Jiedu Tang (See Section on Black Carbuncle)
[Prescription Verse] E Zhang Feng (Goose Palm Wind) arises in the palm, characterized by dry, cracked skin with purple and white patches. This results from residual toxins of Yangmei Chuang (Syphilitic Chancre) not fully cleared, combined with blood dryness, and further complicated by wind-toxin stagnation.
[Annotation] This condition arises in the palm due to incomplete clearance of residual toxins from Yangmei Chuang, compounded by blood dryness and invasion of wind-toxin, leading to stagnation. Initially, purple and white spots appear, with layers of white peeling skin forming; the texture becomes hard and thick, dry and cracked, spreading over the entire hand. Externally, wash with Er Fan San (Two Alum Powder) and apply San You Gao (Three Ointment). Internally, use the formula for Qufeng Dihuang Wan (Wind-Dispersing Rehmannia Pill), adding Tu Fuling (Smilax Glabra Rhizome), Baixianpi (Dictamnus Root Bark), and Danggui (Angelica Sinensis) as adjuvants, processed into pills for effective administration. If the condition persists for years and becomes a tinea infection, it is difficult to cure. There is another condition where, without prior syphilis, there is unexplained dryness, itching, and peeling of the palm, progressing to dry cracking and slight pain, named "Zhang Xin Feng" (Palm Center Wind). This is caused by heat in the spleen and stomach, blood dryness generating wind, and blood failing to nourish the skin. One should take Qufeng Dihuang Wan and externally apply Runji Gao (Moisturizing Muscle Ointment); long-term application will lead to recovery.
Formula: Qufeng Dihuang Wan
Composition: Shengdi (Raw Rehmanniae Radix) and Shudi (Prepared Rehmanniae Radix) (each 4 liang)
Baijili (Tribuli Fructus) and Chuan Niuxi (Achyranthis Bidentatae Radix) (wine-washed, each 3 liang)
Zhimu (Anemarrhenae Rhizoma) and Huangbai (Phellodendri Cortex)
Gouqizi (Lycii Fructus) (each 2 liang) and Tusizi (Cuscutae Semen) (wine-processed)
Duhuo (Angelicae Pubescentis Radix) (1 liang)
Grind all into fine powder, mix with refined honey to form pills the size of Sophora seeds. Take 3 qian per dose, washed down with yellow wine; in summer, wash down with light salt water.
[Prescription Verse] Qufeng Dihuang clears blood heat; Goose Palm Wind heals upon ingestion. Zhimu, Huangbai, Jili, Niuxi, and Tusi, mixed with Duhuo and Gouqi, ground together and blended with refined honey.
Another Method: Er Fan San
Composition: Bai Fan (Alumen) and Zao Fan (Melanterite) (each 4 liang)
Cha'er (Theae Folium / Camellia Seed residue) (5 qian) and Ce Baiye (Biota Orientalis Leaf) (8 liang)
Use ten bowls of water, boil several times until rolling, then set aside. First, apply Tung Oil (Verniciae Folii Oleum) to the affected area. Then, soak a paper wick in Tung Oil, ignite it, and fumigate the affected area for a period. Next, pour the aforementioned decoction into a clean wooden bucket while hot. Place the hand over the bucket, sealing the mouth of the bucket tightly with cloth to prevent steam leakage. Fumigate the hands with the medicinal vapor. When slightly warm, pour the liquid into a basin, soak and wash for a considerable time; one session may suffice. Do not touch water for seven days.
[Prescription Verse] Er Fan treats purple and white spots arising in the palm; Boil Alum, Cha'er, and Biota leaves. First apply Tung Oil to the lesion, then fumigate with an oil-soaked wick before washing for cure.
Another Method: San You Gao
Composition: Niu You (Beef Tallow) and Bai You (Biota Oil)
Xiangyou (Sesame Oil) and Yin Zhu (Cinnabar) (each 1 qian)
Guan Fen (Lead Carbonate) and Shexiang (Moschus) (finely ground, each 2 qian)
Melt the three oils together over fire, add 1 liang of Yellow Beeswax, melt completely, then remove from fire. Add Cinnabar, Moschus, and Lead Carbonate powders, stir evenly to form an ointment. Apply to the affected area and bake with fire until the oil dries but the skin remains moist.
[Prescription Verse] San You Gao moisturizes Goose Palm Wind; Initial spots gradually crack with dryness and itching. Beef tallow, Biota oil, sesame oil, Cinnabar, powder, and Moschus; boiled with wax, applied to lesions and baked over fire.
