夫五脏不调，则三焦气满，满则气游于内，不能宣散，故其病但烦满虚胀。
肺之积气，在于右胁；肝之积气，在于左胁。二脏虚实不和，气蓄于内，故胸胁支满。
春脉不及，令人胸痛引背，下则两胁胀满。寸口脉滑为阳实，胸中逆满也。
寒冷在内，与脏腑相搏，积于胁下，冷乘于气，气则逆上，冲于胸胁，故上气而胸胁支
阴气积于内，久而不已，则生寒，寒气与脏气相搏，冲于胸胁，故支满。
夫虚极之人，荣卫减耗，腑脏虚弱，气行不足，所以呼吸气短也。
夫走马及人走，则大动于气，气逆于胸内，未得宣散，而又饮水，水搏于气，故有上气
夫食热皆触动肺气，则热聚肺间，热气未歇，而饮冷水，水入于肺，冷热相搏，气聚不
宣，为冷所乘，故令发气。
夫气分者，由水饮搏于气，结聚所成。气之流行，常无壅滞，若有停积，水饮搏于气，
则气分结而住，故云气分。
凡香港脚病，皆由感风毒所致。得此病，多不即觉，或先无他疾，而忽得之；或因众病后
得之。初甚微，饮食嬉戏，气力如故，当熟察之。
其状∶自膝至脚有不仁，或若痹，或淫淫如虫所缘，或脚指及膝胫洒洒尔，或脚屈弱不
能行，或微肿，或酷冷，或痛疼，或缓从不随，或挛急；或至困能饮食者，或有不能者，或
见饮食而呕吐，恶闻食臭；或有物如指，发于 肠，迳上冲心，气上者；或举体转筋
，或壮热、头痛；或胸头冲悸，寝处不欲见明；或腹内苦痛而兼下者；或言语错乱，有善忘
误者；或眼浊，精神昏愦者。此皆病之证也，若治之缓，便上入腹。入腹或肿，或不肿，胸
胁满，气上便杀人。急者不全日，缓者或一、二、三日。初得此病，便宜速治之，不同常病
。
病既入脏，其脉有三品，内外证候相似，但脉异耳。若病患脉得浮大而缓，宜服续命汤
两剂。若风盛，宜作越婢汤加术四两。若脉转快而紧，宜服竹沥汤。脉微而弱，宜服风
引汤二三剂。此皆多是因虚而得。若大虚乏气短，可以间作补汤，随病体之冷热而用。若未
愈，更作竹沥汤。
若病患脉浮大而紧快，此是三品之最恶脉。脉或沉细而快者，此脉正与浮大而
紧者同是恶脉。浮大者，病在外；沉细者，病在内，治亦不异，当消息以意耳。其形或尚可
，而手脚未及至弱，数日之内，上气便死。如此之脉，急服竹沥汤，日一剂，汤势恒令相及
，勿令半日之内空无汤也。若服竹沥汤得下者必佳。此汤竹汁多，服之，皆须热服。
不热，辄停在胸膈，更为人患。若已服数剂，病及脉势未折，而若胀满者，可以大鳖甲汤下
之。汤热尽而不得下，可以丸药助令得下；下后更服竹沥汤，趣令脉势折，气息料理乃佳。
江东、岭南，土地卑下，风湿之气，易伤于人。初得此病，多从下上，所以脚先屈弱，
然后毒瓦斯循经络，渐入腑脏，腑脏受邪，气便喘满。以其病从脚起，故名香港脚。其汤熨针石
，别有正方，补养宣导，今附于后。
《养生方·导引法》云∶坐，两足长舒，自纵身，纳气向下，使心内柔和适散；然后屈
一足，安膝下，长舒一足，仰足指向上使急；仰眠，头不至席，两手急努向前，头向上努挽
。一时各各取势，来去二七，递互亦然。去脚疼、腰膊冷、血冷、风痹、日日渐损。
又云∶覆卧，傍视，立两踵，伸腰，以鼻纳气，自极七息。除脚中弦痛、转筋、脚
酸疼，脚痹弱。
又云∶舒两足坐，散气向涌泉，可三通。气彻到始收；右足屈卷，将两手急捉脚涌泉，
挽。足踏手挽，一时取势。手足用力，送气向下，三七，不失气。数寻。去肾内冷气、膝冷
，脚疼也。
又云∶一足屈之，足指仰，使急；一足安膝头。散心，两足跟出气向下。一手拓膝头向
下急捺，一手向后拓席。一时极势，左右亦然，二七。去膝髀疼急。
又云∶一足踏地，一足向后，将足解溪安 上。急努两手，偏相向后，侧身如转，极势
二七，左右亦然。去足疼痛痹急、腰痛也。
五脏功能失调，会导致三焦气机壅滞，气机壅滞则气在体内游走而不能宣散，所以病症表现为烦闷、虚胀。
肺的积气，停留在右胁部；肝的积气，停留在左胁部。这两脏虚实不调，气蓄积在体内，所以出现胸胁支撑胀满的症状。
春季脉象不及（虚弱），会让人胸痛牵引至背部，向下则导致两胁胀满。寸口脉滑属于阳实证，表现为胸中气逆胀满。
寒气积聚在体内，与脏腑之气相搏结，堆积在胁下，寒邪侵袭气机，导致气逆向上，冲击胸胁，所以出现上气（气逆）和胸胁支撑胀满。
阴气积聚在体内，久治不愈，则产生寒邪，寒气与脏腑之气相搏结，冲击胸胁，所以出现支撑胀满。
极度虚弱的人，营卫之气耗损减少，脏腑虚弱，气行不足，所以呼吸气短。
如果是骑马或奔跑，会导致体内气机剧烈动荡，气逆于胸内，未能宣散，此时又饮水，水气与逆气相搏结，所以会出现上气。
进食热食都会触动肺气，热气聚集在肺间，热气未消，又饮用冷水，水进入肺部，冷热相互搏结，气机聚而不散，被冷邪所乘，所以引发气逆。
所谓“气分”病，是由于水饮搏结于气，结聚而成的。气的流行通常没有壅滞，如果有停积，水饮搏结于气，就会导致气分结聚而停留，所以称为气分。
凡是香港脚病（脚气病），都是由感受风毒所致。得此病后，往往不会立即察觉，或者之前没有其他疾病，突然患病；或者在其他疾病之后患上。起初症状很轻微，饮食嬉戏如常，气力也正常，应当仔细察辨。
其症状表现：从膝盖到脚部感觉麻木不仁，或者像痹证一样，或者有虫爬般的瘙痒感，或者脚趾及小腿发凉颤抖，或者脚屈曲软弱不能行走，或者轻微肿胀，或者酷冷，或者疼痛，或者松弛无力不随使唤，或者拘挛紧急；有的虽然困倦但能进食，有的不能进食，或者见到食物就呕吐，厌恶食物的气味；或者有物状如手指，生于肠间，径直上冲心脏，导致气上逆；或者全身转筋，或者高热、头痛；或者心胸悸动不安，睡觉躺着时不喜欢光亮；或者腹内苦痛并伴有腹泻；或者言语错乱，容易遗忘错误；或者眼睛浑浊，精神昏沉。这些都是该病的证候，如果治疗迟缓，病邪就会上行入腹。病入腹后，腹部可能肿胀，也可能不肿胀，胸胁胀满，气上逆就会致死。急性的不到一天，慢性的可能一两天或三天。刚得此病，就应该迅速治疗，不同于普通疾病。
病邪既已入脏，脉象有三种情况，内外证候相似，只是脉象不同。如果患者脉象浮大而缓，适宜服用续命汤两剂。如果风邪盛，适宜用越婢汤加白术四两。如果脉象转快而紧，适宜服用竹沥汤。脉象微而弱，适宜服用风引汤二三剂。这些大多是因为体虚而得的。如果大虚且气短，可以间隔服用补益汤药，根据病体的寒热属性来选用。如果未痊愈，再服用竹沥汤。
如果患者脉象浮大而紧快，这是三种脉象中最恶劣的脉象。脉象沉细而快的，这种脉象与浮大而紧的脉象同样属于恶脉。浮大的脉象，病位在外；沉细的脉象，病位在内，治疗方法也不相异，应当凭心意斟酌处理。病情或许尚可，手脚还未至于极度虚弱，但在数日之内，因上气而死。遇到这样的脉象，应紧急服用竹沥汤，每日一剂，汤药的势头要持续不断，不要让半天之内没有服药。如果服用竹沥汤后大便通畅是最佳效果。此汤竹汁多，服用时都必须热服。如果不热，就会停滞在胸膈，反而成为人的祸患。如果已经服用几剂，病势和脉势仍未减退，而出现胀满的情况，可以用大鳖甲汤攻下。汤药热尽后仍不能通便，可以用丸药辅助使其通便；通便后再服用竹沥汤，促使脉势减退，气息调理好才佳。
江东、岭南地区，地势低洼，风湿之气容易伤人。初得此病，多从下部向上发展，所以脚先屈曲软弱，然后毒瓦斯顺着经络，逐渐侵入腑脏，腑脏受邪，气机就会喘满。因为此病从脚起，所以名叫香港脚。关于汤药熨贴、针刺砭石，另有专门的方剂，补养宣导的方法，现在附在后面。
《养生方·导引法》说：坐位，两脚伸直，舒展身体，将气纳向下，使内心柔和舒适发散；然后屈起一只脚，膝下安顿，另一只脚长伸，脚尖仰起向上用力；仰卧，头不接触席子，两手用力向前努，头向上挽。每个动作同时取势，往返十四次，交替进行也是如此。可去除脚疼、腰背冷、血冷、风痹，日渐损耗。
又说：俯卧，向旁看，竖起两个脚跟，伸展腰部，用鼻吸气，尽力做到七次呼吸。可去除脚中弦痛、转筋、脚酸痛、脚痹弱。
又说：舒开两脚坐，将气散向涌泉穴，可做三次。气通达后才收回；右脚屈卷，用两手用力抓住脚底的涌泉穴，向后挽拉。脚踩手挽，同时取势。手足用力，送气向下，做二十一次，不使气漏失。反复寻找这种感觉。可去除肾内冷气、膝冷、脚疼。
又说：一只脚屈起，脚趾仰起用力；另一只脚安放在膝头。散心，两脚脚跟呼气向下。一只手按压膝头向下用力，另一只手向后按压席子。同时达到极致姿势，左右亦然，做十四次。可去除膝髀疼痛紧急。
又说：一只脚踏地，一只脚向后，将足踝部的解溪穴安放其上。两手用力偏相向后，侧身如同转动，达到极致姿势十四次，左右亦然。可去除足部疼痛痹急、腰痛。
When the five Zang organs are disharmonious, the Qi of the Sanjiao (Triple Burner) becomes full. When full, Qi wanders internally and cannot be diffused, resulting in symptoms of vexation, fullness, and empty distension.
The accumulation of Lung Qi resides in the right hypochondrium; the accumulation of Liver Qi resides in the left hypochondrium. Due to the disharmony of deficiency and excess in these two organs, Qi accumulates internally, causing a sensation of support and fullness in the chest and hypochondrium.
A deficient pulse in Spring causes chest pain radiating to the back, and downward, distension and fullness in both hypochondria. A slippery pulse at the Cun Kou (Radial Artery) indicates Yang Excess, manifesting as rebellious fullness in the chest.
Cold accumulating internally clashes with the Qi of the Zang organs, gathering under the hypochondrium. Cold attacks the Qi, causing it to rebel upward and rush into the chest and hypochondrium, thus causing rebellious Qi (Shang Qi) and a sensation of support and fullness in the chest and hypochondrium.
Yin Qi accumulating internally, if not resolved for a long time, generates Cold. This Cold Qi clashes with the organ Qi, rushing into the chest and hypochondrium, causing support and fullness.
In individuals of extreme deficiency, Ying (Nutritive) and Wei (Defensive) Qi are depleted, and the Zang and Fu organs are weak. With insufficient Qi movement, breathing becomes short.
Riding horses or running causes vigorous disturbance of Qi. If Qi rebels within the chest and is not diffused, followed by drinking water, the water clashes with the Qi, resulting in rebellious Qi.
Consuming hot food stirs Lung Qi, causing heat to gather in the Lungs. If cold water is drunk before this heat subsides, the water enters the Lungs. The clash between cold and heat causes Qi to aggregate without diffusion, attacked by Cold, leading to the onset of rebellious Qi.
The condition known as "Qi Fen" (Qi Division/Segmentation) arises from fluid retention clashing with Qi, forming aggregates. Normally, Qi flows without obstruction. If stagnation occurs, fluid retention clashes with Qi, causing Qi to segment and remain stationary, hence termed "Qi Fen."
All cases of Hong Kong Foot disease (Jiaoxi / Foot Qi) are caused by contracting Wind-Toxin. Upon contracting this disease, one often does not immediately realize it; sometimes there were no prior illnesses, and it appeared suddenly; or it occurred after various other diseases. Initially, symptoms are subtle; diet, play, and strength remain normal, so careful observation is required.
Its manifestations include: numbness and insensitivity from the knees to the feet, or sensations resembling Bi syndrome (Obstruction), or itching like insects crawling, or chills in the toes and calves, or weakness and inability to walk due to flexion, or slight swelling, or extreme cold, or pain, or flaccidity and lack of control, or spasms and tightness; some may be fatigued but able to eat, others unable to eat, or vomiting upon seeing food, and aversion to food odors; or a sensation of an object like a finger arising from the intestines and rushing upward to strike the Heart, causing Qi rebellion; or generalized muscle twitching/spasms, or high fever and headache; or palpitations in the chest and head, unwillingness to see light while lying down; or severe abdominal pain accompanied by diarrhea; or confused speech and forgetfulness; or turbid vision and mental confusion. These are all signs of the disease. If treatment is delayed, the pathogen will enter the abdomen. Once in the abdomen, there may be swelling or none, along with chest and hypochondrial fullness. Rebellious Qi can be fatal. Acute cases may die within a day; chronic cases may take one to three days. Upon initial contraction, immediate treatment is necessary, unlike ordinary diseases.
Once the disease enters the Zang organs, there are three types of pulses. The internal and external signs are similar, differing only in the pulse. If the patient's pulse is floating, large, and slow, Xuming Tang (Cure-all Decoction) should be administered for two doses. If Wind is predominant, Yueshi Tang (Goose Puffer Decoction) with four liang of Baizhu (Atractylodis Macrocephalae Rhizoma) should be used. If the pulse becomes rapid and tight, Zhuli Tang (Bamboo Juice Decoction) is appropriate. If the pulse is faint and weak, Fengyin Tang (Wind-Repelling Decoction) for two to three doses is suitable. These conditions mostly arise from deficiency. For severe deficiency with shortness of breath, tonifying decoctions can be administered intermittently, selected according to the cold or heat nature of the patient's constitution. If not cured, administer Zhuli Tang again.
If the patient's pulse is floating, large, tight, and rapid, this is the most ominous of the three pulse types. A pulse that is deep, fine, and rapid is equally ominous, similar to the floating, large, and tight pulse. A floating pulse indicates the disease is external; a deep, fine pulse indicates the disease is internal. The treatment principle remains the same, requiring careful judgment. Although the physical form may still appear acceptable and limbs not yet extremely weak, death from rebellious Qi may occur within a few days. For such pulses, urgently administer Zhuli Tang, one dose daily. Ensure the therapeutic effect is continuous; do not allow more than half a day without medication. It is best if Zhuli Tang induces bowel movement. Since this decoction contains much bamboo juice, it must be taken hot. If not hot, it will stagnate in the chest and diaphragm, causing further harm. If several doses have been taken but the disease and pulse momentum have not subsided, and distension occurs, Dabiejia Tang (Large Turtle Shell Decoction) can be used to purge. If the decoction is exhausted and defecation has not occurred, pill medicines can be used to assist. After purgation, resume Zhuli Tang to reduce the pulse momentum and regulate respiration.
In Jiangdong and Lingnan regions, where the land is low and damp, Wind-Dampness easily injures people. Initial contraction of this disease often progresses upward from below, so the feet become weak and flexed first, then the Toxin follows the meridians, gradually entering the Fu and Zang organs. Once the organs are invaded, Qi becomes asthmatic and full. Because the disease originates from the feet, it is named Hong Kong Foot (Foot Qi). Regarding herbal decoctions, moxibustion, acupuncture, and stone therapy, there are separate specific formulas. Methods for nourishment and Daoyin (guiding and pulling exercises) are attached below.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) · *Daoyin Fa* (Exercise Method) states: Sit with both legs extended straight. Stretch the body, draw Qi downward, making the heart soft and comfortable. Then, flex one leg, place the knee down, extend the other leg long, and point the toes upward forcefully. Lie supine with the head not touching the mat. Push hands forward forcefully and pull the head upward. Perform each posture simultaneously, repeating fourteen times, alternating sides. This removes foot pain, coldness in the waist and shoulders, cold blood, and Wind-Bi, preventing gradual deterioration.
It also states: Prone position, look sideways, stand on both heels, extend the waist, inhale through the nose, reaching maximum capacity for seven breaths. This removes string-like pain, spasms, soreness, numbness, and weakness in the feet.
It also states: Sit with legs spread out. Disperse Qi toward Yongquan (KI1, Bubbling Spring). Repeat three times. Only retract when Qi penetrates fully. Flex the right foot and roll it up. Grasp the Yongquan point on the sole with both hands and pull backward. Step on the hand while pulling, taking the posture simultaneously. Apply force with hands and feet, sending Qi downward, repeating twenty-one times, ensuring Qi is not lost. Search for this sensation repeatedly. This removes internal Kidney Cold, knee coldness, and foot pain.
It also states: Flex one foot, pointing toes upward forcefully; place the other foot on the knee. Calm the mind, exhale Qi downward from both heel pads. Press one knee downward forcefully with one hand, press the mat backward with the other. Reach the extreme posture simultaneously, repeating fourteen times, alternating sides. This removes pain and urgency in the knees and thighs.
It also states: One foot flat on the ground, the other foot backward, placing the Jiexi (ST41, Solving Stream) point above. Push both hands backward forcefully, turning the side body as if rotating, reaching the extreme posture fourteen times, alternating sides. This removes foot pain, numbness, urgency, and lower back pain.
