申斗垣曰∶血槽风生小腿实处可治，毒瓦斯多流脚面，如脚发背。（《启玄》）
陈实功曰∶湿肿者胸膈不宽，小水不利，而目浮肿，渐至遍身，此乃土伤不能
主化之故也。有饮食后骤受风寒，有饥渴时误餐生冷，寒积于中，食不克化，皆能
致之。治当疏通稼土，温养脾元，则小水自利，浮肿自消，二蛟散主之。（《正宗》）
敷水肿

王肯堂曰∶肾脏风属肾，虚风邪乘于 胫，以致皮肤如癣，或渐延上腿，久则
延及遍身，外证则瘙痒成疮，脓水淋漓，眼目昏花，内证则口燥舌干，腰腿倦怠，吐
痰发热，盗汗体疲，治当用六味地黄丸。（《准绳》）
《心法》曰∶肾气游风多生于肾虚之人，腿肚红肿，形如云片，游走不定，痛如火
烘，此由肾热内蕴，外受风邪，膀胱气滞而成。
肾气游风红肿痛疼如烘 豆腐研调，黄柏末敷之。

共研细末。用香油一两，入血余栗子大一团，炸枯去渣。再入黄蜡一两，白胶

王肯堂曰∶湿毒流注生足胫之间，生疮状如牛眼，或紫或黑，脓水淋漓，止处
即溃烂，久而不敛，乃暴风疾雨，寒湿暑气侵入腠理而成。（《准绳》）
又曰∶下注疮又名湿毒疮。生脚膝间，脓水不绝，连年不愈，因脾胃亏虚，湿热
下注，以致肌肉不仁而成疮也。在外属足太阳少阳经，在内属足厥阴太阴经。（女贞叶贴之效。）
胡公弼曰∶皮如针眼，淌水腥臭，腿
脚延蔓者是也。拖纸膏主之。（《青囊》）
申斗垣曰∶两腿腐烂，臭气难闻者是也。乃湿热为患，宜清湿热。（《启玄》）
凡湿毒所生之疮，皆在两足胫、足踝、足背、足跟。初起微痒，水出久而不愈，内
服补中益气汤合二妙散，外搽制柏散为主。（《良规》）
《心法》曰∶此症生于腿胫，流行不定，或发一二处，疮口形似牛眼，根脚漫肿。轻
则色紫，重则色黑，溃破脓水浸损好肉，破烂日久不敛，乃暴风疾雨，寒湿暑火，侵
入肌肤而成也。初觉急服荆防通圣散加木瓜、牛膝、防己、苍术消之；若腿胫至晚
发热者，宜服当归拈痛汤加牛膝肿痛全消，再搽轻粉散敛之。（《金鉴》）
申斗垣说：血槽风生于小腿坚实部位可以治疗，毒气多流注于脚面，类似于脚发背。（《启玄》）
陈实功说：湿肿表现为胸膈部不宽畅，小便不利，眼睛浮肿，逐渐蔓延至全身，这是脾土受损不能正常运化水湿的缘故。有的在饮食后突然受风寒侵袭，有的在饥渴时误食生冷食物，寒气积聚在体内，食物无法消化，都能导致此病。治疗应当疏通脾土，温养脾胃元气，那么小便自然通畅，浮肿自然消退，以二蛟散为主方治疗。（《正宗》）
敷水肿方：
干黄土（四两） 朴硝（一两） 生大黄（二两）
研成细末。用葱汁调和后外敷。
王肯堂说：肾脏风属于肾脏病变，虚风邪气乘袭胫部，导致皮肤像癣一样，或者逐渐向上蔓延至大腿，时间久了则蔓延至全身。外在症状是瘙痒形成疮疡，脓水淋漓；内在症状是口燥舌干，腰腿倦怠，吐痰发热，盗汗身体疲乏，治疗应当使用六味地黄丸。（《准绳》）
《心法》说：肾气游风多发生于肾虚之人，小腿肚红肿，形状像云片，游走不定，疼痛如火烧，这是由于肾热内蕴，外受风邪，膀胱气机阻滞而形成的。
肾气游风红肿疼痛如火烧：豆腐研碎调匀，黄柏末外敷。
黄蜡膏：
龙骨（缺重量） 赤石脂（缺重量） 血竭（各三钱）
共同研成细末。用香油一两，加入头发团如栗子大小，炸枯后去渣。再加入黄蜡一两，白胶香三钱熔化离火，然后加入前三味药末搅拌均匀，冷却后盛于瓷罐中，使用时捏成薄片贴在疮上，用绢帛绑紧固定，三天后翻转贴换。
王肯堂说：湿毒流注生于足胫之间，生疮形状像牛眼，颜色或紫或黑，脓水淋漓，停止流动的地方即溃烂，时间久了不愈合，这是由暴风疾雨、寒湿暑气侵入腠理而形成的。（《准绳》）
又说：下注疮又名湿毒疮。生于脚膝之间，脓水不绝，连年不愈，是因为脾胃亏虚，湿热下注，导致肌肉失去知觉而形成疮疡。在外属于足太阳经和足少阳经，在内属于足厥阴经和足太阴经。（女贞叶贴敷有效。）
胡公弼说：皮肤像针眼，淌出的水腥臭，腿部蔓延的是这种病。以拖纸膏为主方治疗。（《青囊》）
申斗垣说：双腿腐烂，气味难闻的是这种病。这是湿热为患，应当清利湿热。（《启玄》）
凡是湿毒所生的疮，都生在两小腿、足踝、足背、足跟。初起轻微瘙痒，出水且久不愈合，内服补中益气汤合二妙散，外搽制柏散为主。（《良规》）
《心法》说：此症生于腿胫，流行不定，有时发作一二处，疮口形状像牛眼，根部漫肿。轻的呈紫色，重的呈黑色，溃破后脓水浸损好肉，破烂日久不愈合，这是由暴风疾雨、寒湿暑火侵入肌肤而形成的。初觉不适急服荆防通圣散加木瓜、牛膝、防己、苍术消除；如果腿胫到晚上发热，宜服用当归拈痛汤加牛膝使肿痛全消，再搽轻粉散收敛伤口。（《金鉴》）
Shen Douyuan stated: Blood groove wind (Xuecao Feng) arising in the solid parts of the lower legs is treatable; its toxic qi often flows to the dorsum of the foot, resembling back carbuncle of the foot (Jiao Fabei). (*Qixuan*)
Chen Shigong stated: Dampness swelling (Shizhong) presents with a sensation of fullness and tightness in the chest and diaphragm, difficult urination, and edema of the eyes, which gradually spreads to the whole body. This is due to the injury of Spleen Earth failing to govern transformation and transportation. It can be caused by sudden exposure to wind-cold after eating, or mistakenly consuming raw and cold foods when hungry or thirsty, leading to accumulation of cold in the middle jiao and failure of food digestion. Treatment should focus on unblocking the Spleen Earth and warming and nourishing the Spleen-Yuan Qi, so that urination will naturally become smooth and edema will subside. Erjiao San is the primary formula. (*Zhengzong*)
Application for Edematous Swelling:
Dry Yellow Earth (4 liang), Borax (1 liang), Raw Rhubarb (2 liang).
Grind into fine powder. Mix with juice of green onion for external application.
Wang Kentang stated: Kidney wind (Shenzang Feng) belongs to the Kidney pathology. Deficient wind-pathogens attack the shins, causing the skin to resemble tinea, or gradually spreading up the thighs, and eventually covering the whole body if prolonged. External manifestations include itching leading to sores with dripping pus and fluid; internal manifestations include dry mouth and tongue, fatigue of the waist and legs, expectoration with fever, night sweats, and general debility. Treatment should utilize Liuwei Dihuang Wan. (*Zhunsheng*)
*Xinfa* states: Kidney qi wandering wind (Shenqi Youfeng) mostly occurs in individuals with Kidney deficiency. The calf muscles become red and swollen, shaped like cloud patches, moving unpredictably, with pain feeling like burning. This results from internal accumulation of Kidney heat, external invasion of wind pathogens, and stagnation of Bladder Qi.
For Kidney qi wandering wind with redness, swelling, and burning pain: Grind tofu into a paste, apply with powder of Phellodendri Cortex (Huangbai).
Yellow Wax Ointment (Huanglagao):
Dragon Bone (Longgu) [weight missing], Red Halloysite (Chishizhi) [weight missing], Dragon's Blood (Xuexie) (3 qian each).
Grind all into fine powder. Use 1 liang of sesame oil, add a ball of hair (Cilia) the size of a chestnut, fry until withered, then remove dregs. Add 1 liang of yellow wax and 3 qian of White Rosin (Baijiaoxiang), melt off the fire, then stir in the three powdered ingredients evenly. Store in a porcelain jar after cooling. When using, pinch into thin slices and apply to the sore, bind firmly with silk cloth, and replace every three days.
Wang Kentang stated: Damp-toxin flowing collection (Shidu Liuzhu) arises between the feet and shins. The sores resemble ox eyes, appearing purple or black, with dripping pus and fluid. Where the flow stops, ulceration occurs; if prolonged, it does not heal. This is formed by invasion of strong winds, heavy rains, cold-dampness, and summer-heat into the interstices. (*Zhunsheng*)
He also stated: Lower-flowing sores (Xiazhu Chuang), also known as damp-toxin sores (Shiduchuang), arise between the feet and knees, with continuous pus discharge and non-healing over years. This is due to deficiency of Spleen and Stomach, with damp-heat flowing downward, causing muscle insensibility and formation of sores. Externally, it relates to the Foot-Taiyang and Foot-Shaoyang meridians; internally, to the Foot-Jueyin and Foot-Taiyin meridians. (Application of Ligustrum lucidum leaves is effective.)
Hu Gongbi stated: Skin resembling pinpricks, oozing foul-smelling water, with spreading on legs and feet is this condition. Tuozhi Gao is the primary formula. (*Qingnang*)
Shen Douyuan stated: Rotting of both legs with unbearable odor is this condition. It is caused by damp-heat and should be treated by clearing damp-heat. (*Qixuan*)
Generally, sores generated by damp-toxin appear on the calves, ankles, dorsum of the feet, and heels. Initially, there is slight itching, oozing fluid, and chronic non-healing. Internal treatment primarily uses Buzhong Yiqi Tang combined with Ermiao San; external application primarily uses Zhibai San. (*Lianggui*)
*Xinfa* states: This syndrome arises in the shins, spreading unpredictably, sometimes appearing in one or two places. The sore opening resembles an ox eye, with diffuse swelling at the base. Mild cases are purple; severe cases are black. After ulceration, pus infiltrates and damages healthy flesh, resulting in long-standing non-healing wounds. This is caused by invasion of strong winds, heavy rains, cold-dampness, and summer-heat/fire into the skin and muscles. Upon initial sensation, urgently administer Jingfang Tongsheng San added with Fructus Chaenomelis (Mugua), Achyranthis Bidentatae Radix (Niuxi), Akebiae Caulis (Fangji), and Atractylodis Macrocephalae Rhizoma (Cangzhu) to eliminate the pathogen. If the shins feel hot in the evening, take Danggui Niantong Tang added with Niuxi until swelling and pain completely subside, then apply Qingfen San externally to promote healing. (*Jinjian*)
