凡身体虚浮腹大如鼓，手足头面肿大皮肉如瘫而不穿凹凸不定，或胸臆闷塞胁

这种病症有时表现为肘部感觉不强劲，突然晕倒，手足无力或舞动牵拉抽搐，或者手指蜷缩、肢体伸缩不定，四肢冰冷卧倒在地，俗称为“打鸟风”。
所谓“风”，指的就是这种情况。古籍《寒疰》中说：这又被称为“绝风”，症状包括心腹部内部闷痛、懊恼疼痛。呕吐泡沫，时间久了会导致大便出血，吐出青白色的涎液，腰脊僵硬，不知不觉间昏厥倒地，症状与癞病相似。这是因为人体依靠胃气滋养内脏，灌溉经络和肌肤；如果放纵欲望、醉饱过度、房劳过度或忧怒伤身，导致胃气衰竭，进而使经络空虚耗损，那么筋肉就会懈怠松弛，肢体弛缓纵散而不能收摄。此时风邪逐渐侵袭，搏结气血，导致气血涣散，出现困乏、痿顿等症状。治疗可用一粒金丹、夺命还真丹、真方夺命丹、四魔丹等方剂，配合祛风、降火、消痰、调气的药物进行治疗，以免发展成难以治愈的大风（麻风）、皮肤穿烂、瘫痪等重症。
这种病症初起时腹部胀大而四肢消瘦，形态像蛊毒，眼睛发红嘴唇外翻，时间久了则全身肿胀，皮下呈现紫黑色，浮肿虚大，毛发先脱落，形貌变得丑陋，随后腐烂危重困苦，或者身体颤动、口眼歪斜、挛缩弯曲，这又被称为“毕风”。病情凶险危急且迅速，容易传染害人，这是由于气血虚损，导致九种疰毒之虫进入胃腑，流窜蛀蚀五脏所致；也可能是因为寒湿太重，血液停滞在脉络中，虚火搏击而成。治疗可选用救苦回生丹、搜风顺气丸、四魔丹等方剂。这类病症也有因邪祟不正、阴阳受损的缘故。
还有一种情况是面部生疮，像猫儿的眼睛一样，没有光泽色彩，也没有脓液流出，冬天会自行消退，头部和背部都是如此，名叫“寒疮”，这也是一种怪症，是由于多吃鸡、鱼、蒜、韭菜等食物所致，使用温补的方剂即可自愈。
至于历节风、蚝疮、疙瘙、鸡爪风、刺风，都属于痛风类疾病；鱼鳞癣、鹅掌风、雁来风、疹风、干风，都属于痒风类疾病。
皮肤病症的类别非常多。如游走性疼痛的，是风和邪气在体内流行；疼痛固定在一处不动的，是死血积聚；抽掣感游移变化，瞬间如刀锥刺痛，寻找不到具体位置的，是湿气流注于关节；夜间加重白天安静的，是阴邪侵犯阳气；傍晚缓解早晨加重的，是阳邪侵犯阴气；如果遇到阴雨天气或隆冬严寒就发作的，是寒湿凝聚；似痛非痛、洒淅恶寒不知痛处的，是劳损伤及气血，湿痰散走所致。这些都是邪气伤于内，与脏腑相互感应而引发的病症。如果是瘙痒则不同：皮肤表面浮游性的瘙痒，是血虚火气乘袭所致；外表虽痒但内部觉得痛的，是邪气在表而毒素注入于内；用火烙或用热水浇烫后感到舒爽的，是劳伤导致的瘀血凝滞不散；瘙痒且抓挠后又疼痛的，是血虚热气聚集；瘙痒遇阳光则肿起的，是元气虚败，诸火散布于腠理之间。古语说“痛无补法”，又说“痒麻宜补，疼痛宜泻”，以及“诸痛属虚宜补，诸痒属实宜泻”（注：原文逻辑为痛多实宜泻，痒麻多虚宜补，此处依原文语境整理）。实际上，若是邪气充塞经络，补益则会助长邪气为害；若是正气亏虚，泻法则会使邪气深入而无法挽救。
紫云斑、白癜风、大麻风、核桃癣、哑风，都属于冷麻类疾病；脱跟疮、糕疮、蛇皮癣、漏蹄风、血痹、热风，都属于烂秽类疾病。
凡是似痛非痛、似痒非痒，或者抓刺切割都感觉不到，或者按压肌肤如同隔着一层纸的感觉，或者酸楚麻木顽钝之类的，都称为“木”，即麻木严重。凡是疮疡瘙痒破溃，脓血淋漓，浊水滋粘，迸裂皲破，皮下腐败恶臭的，都属于烂坏类疾病。
蛤蟆肿、蝼蛔肿、血风肿、水风肿、蛊风肿、颠风肿，都属于肿胀类疾病；邪魅病、鼓槌病、软瘫、壁泥病、半肢废、泄泻，都属于痿惫类疾病。
凡是身体虚浮，腹部胀大如鼓，手足头面肿大，皮肉松弛如瘫而不穿破，凹凸不定，或者胸膈闷塞，胁肋胀痛，气机升降失常，精神不舒爽，都属于肿胀类疾病；凡是手指挛缩瘸曲，腿脚脚趾跛行，腰背弯曲，口眼歪斜，身体痿软疲困，左瘫右痪，干瘪僵直废弛，行走艰难，都属于痿惫败坏类疾病。
This condition sometimes presents with a lack of strength in the elbows, sudden fainting, weakness or dancing/twitching movements of the hands and feet, or curled fists and uncontrolled extension/flexion of limbs. The limbs become cold, and the patient may lie on the ground; this is colloquially known as "Da Niao Feng" (Bird-Striking Wind).
The term "Wind" refers to this condition. The ancient text *Han Zhu* states: It is also named "Jue Feng" (Severed Wind), characterized by internal stifling and painful distress in the heart and abdomen. Vomiting of froth occurs, and over time, it leads to bleeding from the stool and vomiting of bluish-white saliva. The waist and spine become stiff, and the patient may suddenly collapse without awareness. This resembles Leprosy (Lai Zheng). Generally, the human body relies on Stomach Qi (Stomach Energy) to nourish the interior and irrigate the meridians and skin/muscles. If one indulges excessively in desires, overeating, drinking, sexual exhaustion, or emotional turmoil, causing Stomach Qi to fail, the meridians will become deficient and depleted. Consequently, muscles and sinews become lax and flaccid, and limbs cannot be controlled. As pathogenic Wind gradually combats with Qi and Blood, causing them to scatter, the patient suffers from fatigue, flaccidity, and prostration. Treatment involves using formulas such as Yili Jindan, Duoming Huanzhen Dan, Zhenfang Duoming Dan, and Simo Dan, combined with agents that dispel Wind, clear Heat/Fire, resolve Phlegm, and regulate Qi, to prevent progression into severe Leprosy (Da Feng), involving skin ulceration and paralysis, which are difficult to treat.
In the initial stage of this condition, the abdomen is distended while limbs are emaciated, resembling Gu Poison (Gu Tox). The eyes are red, and lips are everted. Over time, the whole body becomes swollen, with purplish-black discoloration under the skin, presenting as large, empty edema. Hair falls out first, and the appearance becomes ugly. Later, it progresses to rotting, critical distress, tremors, facial paralysis (deviation of mouth and eyes), and contractures; this is also called "Bi Feng". The condition is malignant, dangerous, rapid, and easily contagious/harmful to others. It results from deficiency and damage of Qi and Blood, allowing nine types of Zhuxie parasites to enter the Stomach Fu-organs and corrode the Zang-organs. Alternatively, it may arise from excessive Cold-Dampness, blood stasis in the meridians, and combative Deficient Fire. Treatment selects from Jiuku Huisheng Dan, Soushun Fengqi Wan, and Simo Dan. Such conditions may also result from evil influences and damage to Yin and Yang.
Another type involves sores on the face resembling cat's eyes, lacking luster or color, with no pus discharge, which recede spontaneously in winter, affecting both head and back. This is named "Han Chuang" (Cold Sore), a strange disease caused by excessive consumption of chicken, fish, garlic, and leeks. It heals itself with warming and tonifying formulas.
Li Jie Feng (Joint-Wandering Wind), Hao Chuang (Oyster Sores), Ga Sao, Ji Zhao Feng (Chicken Claw Wind), and Ci Feng (Thorn Wind) all belong to the category of Tong Feng (Gout-like diseases). Yu Lin Xuan (Fish Scale Tinea), E Zhang Feng (Goose Palm Wind), Yan Lai Feng, Zhen Feng, and Gan Feng all belong to the category of Yang Feng (Itchy Wind).
There are many categories of skin diseases. Pain that wanders indicates the circulation of Wind and pathogenic factors. Pain fixed in one place without movement indicates accumulation of dead blood (blood stasis). Twitching sensations that shift rapidly like knife or awl stabs, where the source cannot be found, indicate Dampness flowing into joints. Symptoms worsening at night and quiet during the day indicate Yin pathogens harassing Yang. Relief in the evening and worsening at dawn indicate Yang pathogens harassing Yin. Onset during rainy weather or severe winter cold indicates condensation of Cold-Dampness. Pain that is neither pain nor itchiness, accompanied by chills and unknown location, indicates Qi and Blood injury from overwork with scattering of Damp-Phlegm. All these arise because pathogenic factors injure the interior and correspond with Zang-Fu organs. Regarding itching: superficial floating itching indicates Blood deficiency with Fire attacking. Itching externally but pain internally indicates pathogens in the exterior with toxins injecting inward. Relief after cauterization or hot water application indicates stagnation of stagnant blood from overwork. Itching that becomes painful upon scratching indicates aggregation of Heat due to Blood deficiency. Swelling upon exposure to sunlight indicates failure of Yuan Qi (Original Qi) with various Fires distributing in the Couli (pores/skin interspaces). Ancient texts state "Pain has no tonification method," and "Itching/Numbness should be tonified, Pain should be purged." Actually, if Meridians are filled with pathogens, tonification aids the pathogen; if Zheng Qi (Upright Qi) is deficient, purging draws pathogens deeper, leading to incurable states.
Zi Yun Ban (Purple Cloud Spots), Bai Dian Feng (Vitiligo), Da Ma Feng (Leprosy), He Tao Xuan (Walnut Tinea), and Ya Feng (Mute Wind) all belong to the category of Leng Ma (Cold Numbness). Tuo Gen Chuang (Heel Loss Sores), Gao Chuang, She Pi Xuan (Snake Skin Tinea), Lou Ti Feng, Xue Bi, and Re Feng all belong to the category of Lan Hui (Rotting/Filthy).
Conditions that are neither pain nor itch, or feel like grasping/stabbing/cutting without sensation, or feel like pressing through a paper layer, or involve acid/chilly numbness, are termed "Mu" (Wood-like), meaning severe numbness. Conditions where sores itch, ulcerate, drip pus/blood, ooze turbid sticky fluid, burst, crack, and exhibit subcutaneous rotting/odor belong to the category of Lan Huai (Rotting/Destruction).
Ha Ma Zhong (Toad Swelling), Lou Hui Zhong, Xue Feng Zhong, Shui Feng Zhong, Gu Feng Zhong, and Dian Feng all belong to the category of Zhong Zhang (Swelling). Xie Mei Bing (Evil Spirit Disease), Gu Chui Bing (Drumstick Disease), Ruan Tan (Soft Paralysis), Bi Ni Bing (Wall Mud Disease), Ban Zhi Fei (Hemiplegia), and Xie Xie (Diarrhea) all belong to the category of Wei Bei (Flaccidity/Exhaustion).
Any condition featuring bodily flaccidity, abdominal distension like a drum, swelling of hands/feet/head/face with loose skin not breaking open, irregular convexities/concavities, chest oppression, hypochondriac fullness/pain, impaired Qi ascent/descent, and mental discomfort belongs to the category of Zhong Zhang (Swelling). Any condition featuring finger contractures/deformities, leg/toe limping, kyphosis of waist/back, facial deviation, bodily flaccidity/exhaustion, left/right hemiplegia, emaciation/stiffness/flaccidity, and difficulty walking belongs to the category of Wei Huai (Flaccidity/Destruction).
