祛血之风邪。戒房室三年。针灸药止述类象形。此治肺风之法也。然非止肺脏有之。俗云鼻属肺。而病发于肺。
端而言之不然。如此者。既鼻准肿赤胀。但为疮之类。乃谓血随气化。既气不施化。则血聚矣。然血既聚。
使肉腐烂而生虫也。谓厥阴主生五虫。厥阴为风木。故木主生五虫。盖三焦相火热甚而制金。金衰故木来克侮。

《内经》说：疠风病，是由于营气发热，其气不清净，所以导致鼻梁塌陷、面色败坏，皮肤发生溃疡溃烂。风寒邪气侵入经脉而不去除，这种病叫做疠风。
又说：脉中受风邪久而成疠风。俗称癞病。所以治疗法则说：患大风病，骨节沉重，眉毛胡须脱落，这叫大风。治疗时刺肌肉部位，令患者出汗一百天。王冰注解说：这是泄出卫气的郁热；刺骨髓部位，令患者出汗一百天，这是泄出营气的郁热。总共二百天，等到眉毛胡须重新长出，就停止针刺。此时郁热消退，阴气在体内恢复，所以会多汗且眉毛胡须再生。先服用桦皮散，剂量从少到多，服用五到七天后，灸承浆穴七壮。如果灸疮较轻，可以再灸；待疮口愈合后再灸。之后服用二圣散，以泄热祛除湿血中的风邪。禁止房事三年。上述针灸药物只是列举了类似象形的治法。这是治疗肺风的方法。然而这不仅仅局限于肺脏患病。俗话常说鼻子属肺，疾病发于肺，严格来说是不对的。像这种情况，既然鼻头红肿胀大，只是属于疮疡一类，这是因为血液随着气化运行，既然气不能正常施化，那么血液就会聚积。然而血液既已聚积，会使肌肉腐烂而生虫。认为厥阴经主管生成五种寄生虫，因为厥阴属风木，所以木行主管生成五种寄生虫。大概是因为三焦相火过盛而克制肺金，肺气衰弱，所以木气来乘侮肺金。《内经》说：这是反常的克制（侮胜）。适宜使用泻火热、利气机的方剂。虫子自然就不会产生了。医法说：流动的水不会腐臭，转动的门轴不会被虫蛀。说的就是这个道理。所以这个疾病的本质是血热明显。应当用药缓慢地疏通泄热。煎煮局方内的升麻汤，送服钱乙《小儿药证直诀》中的内泻青丸。其余各条随经络论述。所以患风病的人，阳气首先受到损伤。
桦皮散：治疗肺脏风毒，遍身疮疥，以及瘾疹瘙痒，抓挠后形成疮疡。又治疗面风刺，以及妇女粉刺。
药材：桦皮（四两，烧成灰）、荆芥穗（二两）、甘草（半两，炙）、杏仁（二两，去皮尖，用水一碗在银器内熬至水剩一半，放干）、枳壳（四两，去芦头，用炭火烧至将成灰状，放在湿纸上冷却）。
以上药材除杏仁外，其余研为细末，将杏仁单独研磨极细，然后与诸药混合均匀，放入瓷盒中保存。每次服用三钱，饭后用温酒调服。
二圣散：治疗大风疠疾。
药材：大黄（半两）、皂角刺（三钱，烧成灰）。
先将一二斤皂角刺烧成灰并研细，煎煮半两大黄，用汤药调服二钱。早上服用桦皮散，中午煎升麻汤送服泻青丸，晚上服用二圣散。这几类药，都是为了缓慢疏泄血中的风热。
七圣丸：郁李仁（去皮）、大黄（蒸焙，各一两）、肉桂（去粗皮）、羌活（去芦头）、槟榔（生用）、木香（生用）、川芎（各半两）。
七宣丸：诃黎勒皮、柴胡（去苗洗净）、枳实（未注明炮制，原文空缺或隐含）、木香（各五两）、桃仁（去皮尖，六两）、大黄（面粉包裹煨熟，十五两）、甘草（未注明炮制，原文空缺或隐含，六两）。
这些方剂都治疗风壅邪热，润利大肠。中风、风痫、疠风、大便秘涩，都可以服用。此方出自《局方》，治疗法则说：虽然诃子味道苦涩，但能固摄脏腑。在此利下药中使用诃子，是为了让大黄、枳实缓缓推动陈积，泄去邪气。如果是年老的风秘涩结者，是因为津液在内耗亡，所以不可用峻猛之剂攻下。《内经》说：人四十岁，阴气自然减半，起居能力衰退；五十岁，身体沉重，耳目不聪明；六十岁，阳痿，气大衰，九窍不利，下虚上实，涕泪直流。所以说：懂得这个道理就能强壮，不懂就会衰老。世人都说老年人没有热证，全是虚证，难道不知道四十岁阴气自半吗？所以阴虚阳盛是很明显的。因此下部阴虚，上部阳盛，所以上实下虚。这个原理是很明确的。
The *Neijing* states: Leprosy (Lifeng, leprosy) arises from heat in the Ying (Nutrient) Qi, causing the Qi to become turbid. Consequently, the nasal bridge collapses and the complexion deteriorates, with skin ulcers and sores appearing. When Wind-Cold pathogens lodge in the meridians and do not depart, it is named Lifeng.
It further states: Wind entering the pulse leads to Lifeng, commonly known as "Lei disease" (leprosy). Therefore, the treatment principle states: In cases of severe Wind disease characterized by heavy joints and loss of eyebrows and beard, termed "Da Feng" (Great Wind), needling should target the muscle layer to induce sweating for one hundred days. Wang Bing's commentary notes: This drains the stagnation-heat of the Wei (Defensive) Qi. Needling the bone marrow layer induces sweating for another hundred days, draining the stagnation-heat of the Ying (Nutrient) Qi. After a total of two hundred days, when eyebrows and beard regrow, needling should cease. As the stagnation-heat dissipates and Yin Qi recovers internally, profuse sweating occurs and hair grows back. First, administer Huapi San (Birch Bark Powder), gradually increasing the dose. After five to seven days, moxa-convulsions are applied to Chengjiang (CV24) acupoint—seven moxa cones. If the moxa blisters are mild, repeat moxibustion; once healed, moxa again. Subsequently, administer Ersheng San (Two Sages Powder) to clear heat and expel Wind pathogens from the blood. Abstain from sexual intercourse for three years. The aforementioned acupuncture, moxibustion, and herbal methods merely illustrate symbolic treatments. This is the method for treating Lung Wind. However, this condition is not limited to the Lung organ. Commonly, it is said that the nose belongs to the Lung and diseases originate there, but strictly speaking, this is incorrect. In such cases, since the nasal tip is swollen, red, and distended, it falls under the category of sores/ulcers. This is because Blood follows Qi transformation; if Qi fails to transform properly, Blood accumulates. Once Blood accumulates, it causes flesh to rot and parasites to generate. It is believed that the Jueyin channel governs the generation of five types of parasites; since Jueyin corresponds to Wind-Wood, Wood governs the generation of these parasites. Generally, excessive Fire of the Triple Burner Shaoyang controls Metal (Lung); due to Metal deficiency, Wood overacts upon Metal. The Classic states: "This is an abnormal counter-restriction" (Wu Sheng). One should use formulas that drain Heat/Fire and promote Qi flow. Parasites will naturally cease to exist. Medical principles state: "Flowing water does not rot; a door pivot does not worm." This applies here. Thus, the pathology clearly involves Blood Heat. Medication should be used to gently vent and drain. Decoct Shengma Tang (Cimicifuga Decoction) from the *Formulas of the Imperial Medical Bureau*, and administer Xieqing Wan (Draining Green Pills) from Qian Yi’s works. Other points follow meridian discussions. Therefore, in Wind diseases, Yang Qi is injured first.
Huapi San (Birch Bark Powder): Treats Wind-Toxin in the Lung, widespread skin sores and scabies, urticaria with itching that becomes ulcerated upon scratching. Also treats facial acne and comedones in women.
Ingredients: Birch bark (Si Liang [4 liang], burnt to ash), Jingjie Sui (Schizonepeta Spike, 2 liang), Gancao (Licorice Root, 0.5 liang, honey-fried), Xingren (Apricot Seed, 2 liang, peeled and crushed, boiled in one bowl of water in a silver vessel until half remains, then dried), Zhike (Bitter Orange Fruit, 4 liang, calyx removed, charred with charcoal until nearly ash, cooled on wet paper).
Process: Except for Apricot Seeds, grind the remaining herbs into powder. Separate the Apricot Seeds, grind finely, then mix uniformly with other powders. Store in a porcelain jar. Dosage: 3 Qian per administration, taken after meals with warm wine.
Ersheng San (Two Sages Powder): Treats Great Wind and Leprosy.
Ingredients: Dahuang (Rhubarb Root, 0.5 liang), Zaojiao Ci (Gleditsia Spine, 3 Qian, burnt to ash).
Process: Burn 1–2 Jin of Gleditsia Spines to ash and grind fine. Decoct 0.5 Liang of Rhubarb. Take 2 Qian mixed with decoction. Morning: Huapi San. Noon: Shengma Tang with Xieqing Wan. Evening: Ersheng San. These preparations aim to gently vent and drain Wind-Heat from the Blood.
Qisheng Wan (Seven Sages Pills): Yuliren (Bush Cherry Kernel, peeled), Dahuang (Rhubarb Root, steamed and baked, 1 Liang each), Rougui (Cinnamon Bark, peeled), Qianghuo (Notopterygium Rhizome, calyx removed), Binglang (Areca Seed, raw), Muxiang (Aucklandia Root, raw), Chuanxiong (Sichuan Lovage Rhizome, 0.5 Liang each).
Qixuan Wan (Seven Ventilation Pills): Helile Pi (Pericarpium Chebulae), Chaihu (Bupleurum Root, weed-free and washed), Zhishi (Immature Bitter Orange Fruit, unspecified processing), Muxiang (Aucklandia Root, 5 Liang each), Taoren (Peach Kernel, peeled and crushed, 6 Liang), Dahuang (Rhubarb Root, wrapped in flour and baked, 15 Liang), Gancao (Licorice Root, unspecified processing, 6 Liang).
These treat Wind obstruction with pathogenic Heat, moistening and purging the Large Intestine. Suitable for Stroke, Wind-Seizures, Leprosy, and constipation. The *Ju Fang* treatment principle states: Although Hezi (Chebulic Myrobalan) is astringent and bitter, it stabilizes the Zang-Fu. Used here with purgatives like Dahuang and Zhishi to slowly push out stagnation and drain pathogens. For elderly patients with Wind-induced constipation due to internal depletion of Body Fluids, harsh purgatives must be avoided. The *Neijing* states: At forty, Yin Qi naturally halves, and daily activities decline. At fifty, the body feels heavy, and hearing/vision dim. At sixty, impotence occurs, Qi severely declines, orifices become obstructed, lower deficiency and upper excess manifest, with runny nose and tears. Thus, understanding this brings strength; ignorance brings aging. The world claims the elderly have no Heat and are purely deficient, ignoring that at forty, Yin halves, making Yin Deficiency and Yang Excess evident. Therefore, lower Yin deficiency and upper Yang excess result in Upper Excess and Lower Deficiency. This logic is clear.
