轻者止于足痛，重者由足痛入阴器，抵小腹，历胁肋上头，又重者则香港脚冲心，误治立死。（《苍生司命》）
香港脚之疾，多生于水湿，亦有夹风夹寒夹暑者。其发时则或肿或痛，湿热胜者成水泡疮，或成赤肿丹毒，
或如疝气攻上引下，皆宜审脉验证，详悉内外血气虚实而分治之。（《医彀》）
香港脚乃肾火挟湿，见于皮肉，红肿如云痕，或隐见红色，按之热且痛者是也。红肿自足起，渐行至股，其
势必上升，升至心者不治。急宜治之，勿令上升为妙。（《订补明医指掌》）
湿香港脚一证，始初甚微，人皆认为内外 疮，治不合，因渐重，则中陷边突者有之，四旁紫黯龟拆者有之。
此毒已攻透外，无服走肌充皮等剂，其疮愈添愈开。只宜以荷叶心、 本或甘松煎汤淋洗，收其湿，拔其毒，
仍服宣麻飞步丸，疮口自然渐敛。不可以紧药急收，疮口急合，毒却上攻，为祸亦急。疮虽可恶，却无入腹
攻胃冲心之危，为可喜。（《续易简后集》）（按∶香港脚生疮，既见《外台》引萧亮，及《圣惠方》，宜考。）
香港脚，跟注一孔，深半寸许，每下半日疼异常，此乃脚
气注成漏，以人中白于火上 ，中有水出，滴入疮口。（《要诀》）
道士王裕曰∶有忽患脚心如中箭，发歇不时，此肾之风毒，泻肾愈。（《医说》引《泊宅编》）
死证 《葛氏方》云∶脚弱满而痹。至少腹而小便不利，气上者死。（《医心》）
凡小觉病候有异，即须大怖畏，决意急治之。伤缓气上入腹，或肿或不肿，胸胁逆满，气上肩息，急者死
不旋踵，宽者数日必死，不可不急治也。但看心下急，气喘不停，或自汗数出，或乍寒乍热，其脉促短而数，
呕吐不止者，皆死。（《千金》）（按∶《圣惠》更有上气脉数不得卧者死。）
香港脚之病，传于心肾，则十死不治。入心则恍惚忘谬，呕吐，食不入，眠不安宁，口眼不定，左手寸口脉
乍大乍小、乍有乍无者是也。入肾则腰脚俱肿，小便不通，呻吟不绝，目额皆见黑色，气时上冲胸腹而喘，其
左手尺中脉绝者是也。切宜详审矣。（《中藏经》）
治不得大补大泻 凡香港脚之疾，皆由气实而死，终无一人以服药致虚而殂。故香港脚之人，皆不得大补，
亦不可大泻，终不可畏虚，故预止汤不服也，如此者皆死不治也。（《千金》）
治须顺四时 夫疗香港脚者，须顺四时，春秋二时，宜兼补泻，夏时疾盛，专须汗利，十月以后，乃用
补药，虽小小变通，终不越此法。（《外台》引苏）
凡患香港脚者，虽苦虚羸，不得多服补药，服之胪胀，非泻不瘥，但益虚羸也。唯冬月得用补药，如冬月仍
患气不除者，亦不得服之，可斟酌此。大都患气寻常须微利，但不得
大利益虚耳。凡脚顽至冬则定者多，所以然，冬肾王，王则不受邪，所以腰脚得利也。（同上）
入冬以后，须量人之盛衰，微加滋补；不然则气血日衰，必使年年遇蒸热而作，理之必然也。（《济生》）
禁吐 凡香港脚上冲心者，不宜吐之。（《医心方》引《医门方》）
禁淋洗 服补药与用汤淋洗者，皆医之大禁也。（《活人书》）
最忌用热药蒸泡，恐逼邪气入于经络，为难治也。（《集成》）
最忌补剂及淋洗，并冷草药摊罨。若犯此禁，则毒瓦斯入心，小腹顽痹不仁，或气喘呕吐。（《岭南卫生
方·附录》）
《活人书》云∶凡香港脚服补药及用汤渫洗者，皆医之大禁也。《发明》谓此为南方外感湿气乘虚袭人为肿
痛而言，非为北方内受湿气注下肿痛而言也。盖湿气不能外达，宜淋渫开导泄越其邪也。（《玉机》）
续生诸病治法 夫因患香港脚续生诸病者，则以诸药对之。或小便不利，则以猪苓、茯苓及诸利小便药
治之。大便极坚者，则以五柔麻仁丸等治之。遍体肿满成水病者，则取治水方中诸治水之药治之。余皆仿此，
更无拘忌。（《千金》）

病情较轻者，症状仅局限于足部疼痛；病情较重者，疼痛由足部向上蔓延至阴器，抵达小腹，经过胁肋直至头部；病情更重者，则发展为香港脚冲心（指湿毒之气上攻于心），若误治会立即致死。（《苍生司命》）
香港脚这一疾病，多因水湿之邪引起，也有夹杂风邪、寒邪或暑邪的情况。发作时，患处或肿胀或疼痛，湿热偏盛者会形成水泡疮，或者变成赤肿丹毒，或者像疝气一样攻冲上下，这些都应当仔细诊察脉象和验证症状，详细辨别内外、血气的虚实情况，从而分别进行治疗。（《医彀》）
香港脚是肾中相火挟带湿气，显现于皮肉之间，表现为红肿如同云片痕迹，或者隐约可见红色，按压时感觉发热且疼痛的病症。红肿从足部开始，逐渐上行至大腿，其病势必然向上发展，如果上升到心脏部位则属于不治之症。应当紧急治疗，不要让病势上升才是最好的办法。（《订补明医指掌》）
湿性香港脚这一证候，起初非常轻微，人们都将其认为是内外科的疮疡，治疗不当，因此病情逐渐加重，有的出现中间凹陷边缘突起的现象，有的四周颜色紫暗干裂。此时毒气已经透达外部，如果没有服用宣散麻黄、飞步丸等药物，疮口只会越来越溃烂扩大。只适宜用荷叶心、藁本或甘松煎汤淋洗，以收湿拔毒，同时仍服用宣麻飞步丸，疮口自然会逐渐收敛。不可以使用收敛性强的药物急于闭合疮口，如果疮口急合，毒气反而会上攻，造成的祸害也很急迫。虽然疮疡令人厌恶，但并没有毒气入腹攻击胃腑或冲心的危险，这是值得庆幸的。（《续易简后集》）（按语：香港脚生疮，既见于《外台秘要》引用的萧亮方，也见于《圣惠方》，应当考证。）
香港脚，脚跟处注成一孔，深约半寸，每天下午疼痛异常剧烈，这是脚气注成瘘管，用人中白在火上烧煅，收集其中渗出的水滴入疮口中。（《要诀》）
道士王裕说：有人突然患脚心疼痛如被箭射，发作和停止没有定时，这是肾中的风毒，泻除肾经邪气即可痊愈。（《医说》引用《泊宅编》）
死证 《葛氏方》说：脚部软弱无力且满闷痹阻。病气至少腹并且小便不利，气逆上冲的会死亡。（《医心方》）
凡是稍微感觉到病候有异常，就必须极度恐惧，决意紧急治疗。如果延误治疗，气逆上入腹部，或者肿胀或者不肿胀，胸胁部逆满，气逆上冲至肩部呼吸急促，病情急骤的立刻就会死亡，病情稍缓的几天内也必死无疑，不可不紧急治疗。只要看到心下急迫，气喘不停，或者自汗频频，或者忽冷忽热，脉象促短而数，呕吐不止的，都是死证。（《千金方》）（按语：《圣惠方》还有提到上气脉数不能卧的会死亡。）
香港脚这一疾病，传变到心和肾，则十死无救。传入心脏，会出现神志恍惚、健忘错乱、呕吐、饮食难进、睡眠不安宁、口眼歪斜或抽动，左手寸口脉乍大乍小、乍有乍无，这就是传入心脏的表现。传入肾脏，则腰部和脚部都肿胀，小便不通，呻吟声不断，眼睛和额头都呈现黑色，气时常上冲胸腹而喘息，左手尺中脉绝，这就是传入肾脏的表现。务必详细审察。（《中藏经》）
治疗不得大补大泻 凡是香港脚的疾病，都是因为气实而死，最终没有一个人因为服药导致虚损而死亡的。所以患香港脚的人，都不可以大补，也不可以大泻，最终不要因为害怕虚损，就预先停止服用通利汤药，像这样的人都会死亡且无法救治。（《千金方》）
治疗须顺应四时 治疗香港脚，必须顺应四季变化，春秋两季，宜兼用补法和泻法，夏季疾病盛行，专门需要用发汗和利尿的方法，十月以后，才使用补药，虽然有小小的变通，但最终不超出这个法则。（《外台秘要》引用苏敬）
凡是患香港脚的人，虽然痛苦于身体虚弱消瘦，但不能多服补药，服用补药会导致腹部胀满，如果不泻下就不能痊愈，只会更加增加虚弱消瘦。只有冬季可以使用补药，如果在冬季仍然患有气逆不除的症状，也不得服用补药，可以斟酌这种情况。大多患气逆之症平时需要微微通利，只是不可以过度通利导致虚损罢了。凡是脚部顽疾到了冬季定住的很多，之所以这样，是因为冬季肾气旺盛，旺盛则不受邪气侵袭，所以腰脚得以通利。（同上）
进入冬季以后，必须衡量人的体质强弱，稍微加以滋补；否则气血日渐衰败，必定会使每年遇到蒸热天气时就发病，这是理所当然的。（《济生方》）
禁止催吐 凡是香港脚气上冲心的，不宜使用催吐法。（《医心方》引用《医门方》）
禁止淋洗 服用补药和使用汤药淋洗，都是医生的大禁忌。（《活人书》）
最忌讳使用热药蒸泡，恐怕逼迫邪气进入经络，导致难以治疗。（《集成》）
最忌讳补剂及淋洗，以及冷草药摊敷罨贴。如果触犯这些禁忌，则毒瓦斯进入心脏，小腹顽固痹阻不知痛痒，或者气喘呕吐。（《岭南卫生方·附录》）
《活人书》说：凡是香港脚服用补药及使用汤药淋洗的，都是医生的大禁忌。《本草发明》认为这是针对南方外感湿气乘虚袭人导致肿痛而言，并非针对北方内受湿气注下导致肿痛而言。大概湿气不能向外透达，适宜淋洗开导泄越邪气。（《玉机微义》）
续发诸病治法 因为患香港脚而续发其他疾病的，就用各种药物对症处理。如果小便不利，就用猪苓、茯苓及各种利小便的药物来治疗。大便极坚硬的，就用五柔麻仁丸等药物治疗。遍体肿胀满闷成为水病的，就取治水方中的各种治水药物治疗。其余的都仿照此例，更没有拘泥禁忌。（《千金方》）

Mild cases are limited to foot pain; severe cases progress from foot pain to the genitalia, reaching the lower abdomen, passing through the costal region up to the head; even more severe cases develop into Hong Kong Foot rushing to the heart (referring to damp-toxic qi attacking the heart), and mismanagement leads to immediate death. (*Cangsheng Siming*)
The disease of Hong Kong Foot is mostly caused by water-dampness, but may also be complicated by wind-cold or summer-heat. During attacks, the affected area may swell or hurt. When damp-heat prevails, it forms blister sores, or becomes red swelling and erysipelas, or acts like hernia attacking upwards and downwards. In all these cases, one must carefully examine the pulse and verify symptoms, thoroughly distinguishing between interior/exterior and the deficiency/excess of blood and qi, then treating accordingly. (*Yi Gu*)
Hong Kong Foot is kidney fire carrying dampness, manifesting in the skin and flesh, presenting as red swelling resembling cloud marks, or faintly visible redness, which feels hot and painful upon pressure. The red swelling starts from the feet and gradually moves up to the thighs; its momentum inevitably rises. If it reaches the heart, it is incurable. Urgent treatment is required to prevent the pathogen from rising, which is the best approach. (*Dingbu Mingyi Zhizhang*)
The syndrome of damp-type Hong Kong Foot begins very subtly. People often mistake it for internal or external sores. Due to improper treatment, the condition gradually worsens. Some present with a depressed center and protruding edges, while others show purple-dark, cracked surroundings. At this stage, the toxin has penetrated outward. Without using herbs that disperse and ascend (such as Ephedrae Herba) or promote circulation (such as Feibu Wan), the sores will only become more ulcerated and open. It is advisable to wash with decoctions of Lotus Leaf Heart, Ligusticum Wallichii Rhizome (Gaoben), or Nardostachys Chinensis Radix et Rhizoma (Gansong) to absorb dampness and draw out toxins, while continuing to administer Xuanma Feibu Wan, allowing the sores to heal naturally. One should not use astringent drugs to hastily close the sores; if closed too quickly, the toxin may attack upwards, causing rapid and severe harm. Although the sores are repulsive, there is no danger of the toxin entering the abdomen to attack the stomach or rushing to the heart, which is a cause for relief. (*Xu Yijian Houji*) [Note: Sores arising from Hong Kong Foot are recorded in *Waitai Miyao* citing Xiao Liang, and in *Shenghui Fang*; verification is recommended.]
Hong Kong Foot may present as a single pore at the heel, about half cun deep, with exceptional pain every afternoon. This is foot qi transforming into a fistula. Burn Renzhongbai (Human Tooth Fossil) over fire, collect the exuded water, and drip it into the sore. (*Yaojue*)
Daoist Wang Yu said: Some suddenly suffer from foot sole pain as if pierced by an arrow, occurring intermittently without fixed timing. This is wind-toxin in the kidney; purging the kidney meridian will cure it. (*Yishuo*, citing *Bozhai Bian*)
Death Signs: *Ge Shi Fang* states: Weakness and fullness with bi-syndrome in the legs. If the pathogen reaches the lower abdomen accompanied by dysuria, and qi rebels upward, death ensues. (*Yixin Fang*)
Whenever any abnormality in symptoms is perceived, one must feel extreme alarm and resolve to treat urgently. Delaying treatment allows qi to rebel into the abdomen, causing swelling or non-swelling, chest and hypochondriac fullness and rebellion, and shortness of breath with qi rushing to the shoulders. Acute cases die instantly; milder cases die within days. Urgent treatment is imperative. Look for signs such as urgency below the heart, continuous panting, spontaneous sweating, alternating chills and fever, a hurried, short, and rapid pulse, and incessant vomiting; all indicate death. (*Qianjin Fang*) [Note: *Shenghui Fang* adds that rapid pulse with inability to lie down indicates death.]
When Hong Kong Foot transmits to the heart and kidneys, ten out of ten cases are fatal. Transmission to the heart manifests as mental confusion, forgetfulness, errors in speech/action, vomiting, inability to eat, restless sleep, and twitching of the mouth and eyes. The pulse at the left Cun position fluctuates between large/small and present/absent. Transmission to the kidneys manifests as swelling of both waist and feet, urinary retention, continuous groaning, black discoloration of the eyes and forehead, and wheezing due to qi rushing to the chest and abdomen. The pulse at the left Chi position is absent. Careful examination is essential. (*Zhongzang Jing*)
Treatment: Avoid drastic tonification or purgation. All deaths from Hong Kong Foot result from excess qi; no one dies from deficiency caused by medication. Therefore, patients with Hong Kong Foot should not undergo drastic tonification nor drastic purgation. Do not fear deficiency to the point of prematurely stopping diuretic/decoction treatments; such patients will die and cannot be saved. (*Qianjin Fang*)
Treatment Must Follow the Four Seasons: Treating Hong Kong Foot requires following the seasons. In spring and autumn, combine tonification and purgation. In summer, when the disease is prevalent, focus on sweating and urination. After the tenth month, use tonic medicines. Although minor adjustments are made, the principle remains unchanged. (*Waitai Miyao*, citing Su Jing)
Patients with Hong Kong Foot, despite suffering from weakness and emaciation, should not take excessive tonics. Tonics cause abdominal distension; without purgation, the disease will not improve, and emaciation will worsen. Tonics are only suitable in winter. However, if qi rebellion persists in winter, tonics should still be avoided; judgment is required. Generally, qi rebellion requires mild purgation, but excessive purgation leading to deficiency must be avoided. Most chronic foot conditions stabilize in winter because kidney qi is prosperous in winter, prospering qi resists pathogens, thus allowing the waist and feet to remain clear. (Ibid.)
After entering winter, assess the patient's strength and add mild nourishment; otherwise, qi and blood will decline daily, inevitably causing recurrence during hot, humid periods, which is natural law. (*Jisheng Fang*)
Contraindication: Vomiting. Cases where Hong Kong Foot qi rushes to the heart should not be treated with emetics. (*Yixin Fang*, citing *Yimen Fang*)
Contraindication: Washing/Bathing. Taking tonics and using herbal baths are major taboos for physicians. (*Huren Shu*)
Most taboo: Steeping/bathing with hot medicines. This risks forcing pathogens into the meridians, making them difficult to treat. (*Jicheng*)
Most taboo: Tonic preparations, herbal baths, and cold herbal compresses. Violating these taboos allows toxic vapors to enter the heart, causing stubborn numbness in the lower abdomen, or wheezing and vomiting. (*Lingnan Weisheng Fang · Appendix*)
*Huren Shu* states: Taking tonics and using herbal baths for Hong Kong Foot are major physician taboos. *Bencao Faming* argues this applies to southern external dampness invading deficiency causing swelling/pain, not northern internal dampness sinking downward causing swelling/pain. Since dampness cannot reach the exterior, washing and guiding to vent the pathogen is appropriate. (*Yuji Wei Yi*)
Treatment of Secondary Diseases: For diseases arising secondary to Hong Kong Foot, treat according to the specific symptoms. For dysuria, use Polyporus (Zuling), Poria (Fuling), and other diuretics. For severe constipation, use Wuruomaren Wan. For generalized edema becoming water disease, use formulas from water-draining categories. Others follow this pattern, without rigid restrictions.

Highly efficacious. This herb greatly dissipates swelling and directs qi downward (i.e., this formula). [Cross-reference with slower treatment formulas Mugua San and Binglang Tang.]
*Guangji Fang* for acute Hong Kong Foot rushing to heart with suffocating desire to die:
Arecae Semen (Binglangren, 3 pieces, finely powdered), Zingiberis Rhizoma Recens Juice (Shengjiangzhi, 3 he), Boy's Urine (Tongzi Xiaobian, 2 sheng, fresh, do not warm).

(*Waitai Miyao*) *Jinxiao Fang* saves Hong Kong Foot rushing to heart, highly effective. Binglangren 6 pieces, grind/sift, mix with 0.5 sheng warm boy's urine, take in one dose. If no movement after cooking time, take another half dose as above. Passage indicates cure, very good. (Ibid.) (*Bencao* cites *Guangli Fang* same). For damp Hong Kong Foot attacking chest/heart with wheezing/oppression: Binglang 2 liang, Evodiae Fructus (Wuzhuyu) 3 fen, make powder.

Tang Liu Liuzhou compiled *Jiu Sansi Fang*: In Feb of Yuanhe 12th year, suffered Hong Kong Foot. Midnight, sudden blockage, mass in hypochondrium stone-sized (*Jifeng Fang* says dry foot qi, midnight blockage, left hypochondrium mass soybean-sized). Near death, unconscious for three days due to severe cold, family weeping. Zheng Xunmei of Xingyang passed down Shanmu Tang. After half meal time, severe purgation, three purgations allowed qi to pass and mass to disperse. Pinus Massoniana Nodes (Shanjiejie) 1 da sheng, Cut Citrus Reticulata Leaves (Juye) 1 da sheng (North lacks leaves, use bark substitute), Large Arecae Seeds (Dafu Binglang) 7 pieces, crushed with shell, Boy's Urine (Tongzi Xiaobian) 3 da sheng. Boil together to obtain 1.5 sheng. Divide into two doses. If first dose causes rapid purgation, stop second dose. (*Zhenglei Bencao*) *Xu Yijian Houji* states: For severe toxicity, phlegm rebellion/oppression, wheezing/sweating, coma/spasms/grinding teeth/upward gaze, near death, only Shanmu Jie Tang is supreme, 100% effective, reviving the dying.
Formula for Hong Kong Foot rushing to heart, vexation/oppression/wheezing, inability to sit/lie:

Finely cut herbs. First stir-fry Heidou and Shengjiang until cooked. Then add urine and other herbs. Decoct to 2 sheng. Strain. Take warm 1 small zhan anytime. (*Shenghui Fang*)
If this syndrome is perceived (Note: Preceding text taken entirely from *Zhouhou Beiji Fang*, see previous symptom descriptions for review), first administer Xijiao Xuanfuhua Tang.
Rhinocerotis Cornu (Xijiao), Inulae Flos (Xuanfuhua) (each 2 liang), Citri Reticulatae Pericarpium (Jupi), Poria (Fuling), Zingiberis Rhizoma Recens (Shengjiang) (each 3 liang), Jujubae Fructus (Dazao, 11 pieces), Fermented Soybean (Xiangchi, 1 sheng), Perillae Caulis et Folium (Zisujingye, one handful).
Chop eight ingredients. Boil in 8 sheng of water to obtain 2.7 sheng. Divide into three doses. Wait interval of walking ten li. Stop when qi descends and urination improves. (Cui Shi calls it Xiaoxijiao Tang; if not effective, take subsequent Dayixijiao Tang.) (*Qianjin Fang*) Dayixijiao Tang treats Hong Kong Foot toxin rushing to heart, transforming into water disease with generalized edema and suffocating sensation. Add Baizhu, Guixin, Fangji, Huangqin, Qianhu, Sangbaipipi to this base. *Shenghui Fang* treats miasma-toxin Hong Kong Foot, initial nausea/vexation/dizziness/anorexia, removes Dazao, adds Muxiang, Binglang, Banxia, Gancao.
