表邪遏伏于肺，失于宣散，并嗜烟酒，火毒上熏，久郁热炽，烁腐肺叶，则出秽气，如
臭蛋逼人，虽延迁终不治。
痈疽成脓日久，未经开放，愈酿则热愈盛，热愈盛则蒸灼腐肉变味，愈热愈熟必穿
决而脓出，其气臭过于臭蛋，在四肢总拖连难敛，在身体者难治。
脾肾两虚，气血错乱，湿邪内扰，每临暑湿之令，外湿激动内湿，使足胫皮肤，红
肿坠痛，为肾气游风。用针刺出湿水，将黄柏末、豆腐和敷，内服防己汤。（方见后）。
表虚风入，兼血热皮燥，致皮痒搔落白屑，或生水窠，或有黄白靥，游走不定，（赤
者名赤游风，白者名白游风。）治不易效，久进祛风丸，可退。（方见后。）
常犬咬破皮肉，即上戌毒丹贴膏药，（方见《青囊集》。）四五日可愈。倘不速治，及不戒口，
其毒易散，红肿 痛，烂深淌脓，在上身者，按痈肿治法。在膝盖下者，先提毒三日，再
按疮治法。若疯犬咬者，治法见《青囊集》。
小儿痧疹，热毒未达，伏于肠胃，常悠悠腹痛，头与胸腹皆发热，或全下发热，其
身腹有红紫块点，或隐或现，脉浮数，宜疏散其表。如误以暖药，入腹不救。若蛔犯中
胃作痛，痛有止息，尺脉沉滑，忽大忽小。若寒邪腹痛，脉沉迟，此二症皆不发热。
头面颈项生疡，乃风热上壅居多。头又诸阳所会，误用针灸，似救火沃油，遂漫肿
难挽，至肉桂、麝香，温暖膏药，尤不可贴，亦助火为肿，可畏。
表邪（外感病邪）郁闭伏留于肺，未能及时宣发疏散，加之嗜好烟酒，导致火毒上熏，长期郁结化热炽盛，灼烧腐败肺叶，从而呼出秽浊之气，气味如同臭鸡蛋般令人窒息，即使病程迁延，最终也难以治愈。
痈疽（体表化脓性感染）形成脓液日久，未经切开排脓，越是拖延酿脓则热势越盛，热势越盛则蒸灼腐肉改变气味，热度越高腐熟越快，必然破溃穿决而脓液流出，其气味比臭鸡蛋更臭。若发生在四肢，总是牵连难愈难以收敛；若发生在躯干身体部位，则更难治疗。
脾肾两虚，气血运行错乱，湿邪内扰，每逢暑湿季节，外湿引动内湿，致使小腿及足胫皮肤红肿坠痛，称为肾气游风。采用针刺放出湿水，将黄柏末与豆腐调和后外敷，内服防己汤。（方剂见后文）。
表虚受风邪侵袭，兼有血热皮肤干燥，导致皮肤瘙痒抓落白屑，或生水疱，或有黄白色结痂，游走不定。（红色者名为赤游风，白色者名为白游风。）治疗不易见效，长期服用祛风丸，可以消退。（方剂见后文）。
被正常犬只咬破皮肉，立即贴上“戌毒丹”膏药。（方剂见《青囊集》），四五日可痊愈。倘若不迅速治疗，且不忌口，其毒性容易扩散，出现红肿疼痛，溃烂深且流脓。若伤口在上半身，按照痈肿的治疗方法处理。若在膝盖以下，先提毒三日，再按疮疡治疗方法处理。若是疯狗咬伤，治疗方法见《青囊集》。
小儿患痧疹（麻疹类疾病），热毒未透达，伏留于肠胃，常伴有隐隐腹痛，头部与胸腹皆发热，或全身下部发热，身上腹部有红紫块点，或隐或现，脉象浮数，宜用疏散表邪的方法治疗。如果误用温热药物，进入体内后将无法挽救。若是蛔虫侵犯中焦胃脘引起疼痛，疼痛时有休止，尺脉沉滑，忽大忽小。若是寒邪引起的腹痛，脉象沉迟，这两种症状都不发热。
头面颈项部位生疡，大多因风热上壅所致。头部又是诸阳经交会之处，误用针灸，犹如救火时泼油，导致漫肿难以挽回，至于肉桂、麝香等温暖性质的膏药，尤其不可贴敷，也会助火加重肿胀，令人畏惧。
Exterior pathogens (pathogenic factors from outside) are constrained and latent in the Lung, failing to be diffused and dispersed. Coupled with a habit of smoking and drinking alcohol, fire-toxins ascend and fumigate. Long-term stagnation leads to blazing heat, scorching and corrupting the lung lobes, resulting in the exhalation of foul-smelling air, as offensive as rotten eggs, which is unbearable. Even if the disease lingers, it is ultimately incurable.
When carbuncles and sores (superficial suppurative infections) have formed pus for a long time without being opened, prolonged fermentation causes the heat to intensify. The more intense the heat, the more it steams and burns the flesh, altering its odor. The higher the heat, the faster the rotting; inevitably, it will rupture and discharge pus. Its odor is worse than that of rotten eggs. If occurring on the limbs, it tends to spread and is difficult to heal and close; if occurring on the trunk or body, it is even harder to treat.
Deficiency of both the Spleen and Kidney, chaotic Qi and Blood, and internal disturbance by Dampness often occur during the season of summer-dampness. External dampness stirs up internal dampness, causing redness, swelling, heaviness, and pain in the skin of the lower legs and shanks, known as Shenqi Youfeng (Wandering Wind of Kidney Qi). Acupuncture is used to drain the damp fluid. A paste made of Phellodendri Cortex powder (Huangbai, 黄柏) and tofu is applied externally, while Fangji Tang (Stephania Decoction) is taken internally. (Formula see later).
Due to exterior deficiency allowing wind invasion, combined with blood-heat and dry skin, the skin becomes itchy, shedding white scales when scratched, or forming water blisters, or yellow-white crusts, wandering unpredictably. (Those that are red are named Chiyoufeng [Red Wandering Wind], and those that are white are named Baiyoufeng [White Wandering Wind]). Treatment is difficult to achieve efficacy; long-term administration of Qufeng Wan (Wind-Dispersing Pill) can reduce symptoms. (Formula see later).
If bitten by a normal dog breaking the skin and flesh, immediately apply the Xududan (Dog-Bite Toxin Dan) plaster. (Formula seen in *Qingnang Ji*), healing can occur in four to five days. If not treated promptly, or if dietary restrictions are not observed, the toxin easily spreads, causing redness, swelling, pain, deep ulceration, and pus discharge. If located on the upper body, treat according to the methods for carbuncles and swellings. If located below the knee, first extract the toxin for three days, then treat according to the methods for ulcers. If bitten by a mad dog, refer to the treatment methods in *Qingnang Ji*.
In children suffering from sand-rash (measles-like diseases), if heat-toxins fail to reach the surface and remain latent in the intestines and stomach, there is often lingering abdominal pain. The head, chest, and abdomen all feel feverish, or the lower body feels feverish. Red-purple patches may appear on the body and abdomen, sometimes hidden, sometimes visible. The pulse is floating and rapid. It is appropriate to use methods to disperse the exterior. If mistakenly treated with warming herbs, they enter the abdomen and become incurable. If pain is caused by roundworms invading the middle Jiao/Stomach, the pain has intervals of relief, the radial pulse at the cun position is deep and slippery, fluctuating between large and small. If abdominal pain is caused by cold pathogens, the pulse is deep and slow. Neither of these two conditions presents with fever.
Ulcers arising on the head, face, and neck are mostly due to the upward congestion of wind-heat. The head is the meeting point of all Yang meridians. Misusing acupuncture and moxibustion here is like pouring oil on a fire, leading to diffuse swelling that is difficult to reverse. Furthermore, plasters containing warming ingredients such as Cinnamon Bark (Rougui, 肉桂) and Musk (Shexiang, 麝香) must especially not be applied, as they also aid fire and exacerbate swelling, which is terrifying.
