千金言∶香港脚皆由感风毒所致。又经云∶地之寒暑风湿皆作蒸气，足常履之，遂成香港脚。

或两胫肿满，或足膝枯细，或心中忡悸，或小腹不仁，或举体转筋，或见食吐逆，恶闻食气，
或胸满气急，或遍体酸痛，此其候之不同也。大抵寒中三阳，所患必冷，暑中三阴，所患必

《千金方》说：香港脚（足部肿痛麻木之病）都是由感受风毒所致。又医经云：大地的寒暑风湿之气都化作蒸气，双脚经常踩踏接触，于是形成香港脚。然而虽然说法不同，其实本质是一样的。由此看来，寒暑风湿都能导致此病，不仅仅是风毒而已。香港脚这个病，初起时并不觉得异常，因为其他疾病才引发发作，或者突然感到极度闷乱，经过两三天后才察觉，症状先从脚部开始，有的表现为迟缓虚弱疼痛麻木，有的行走时突然跌倒，有的双小腿肿胀饱满，有的足膝枯瘦细小，有的心中悸动不安，有的小腹感觉迟钝或无知觉，有的全身转筋抽搐，有的见到食物就呕吐反胃，厌恶闻到食物的气味，有的胸中胀满气息急促，有的全身酸痛，这是其症状表现的不同之处。大体来说，寒邪侵入三阳经，患病必然表现为冷症；暑邪侵入三阴经，患病必然表现为热症，这话确实有道理。如果论述其脉象浮而弦的，起因于风；脉象濡而弱的，起因于湿；脉象洪而数的，起因于热；脉象迟而涩的，起因于寒。因风邪引起的通过发汗治愈，因湿邪引起的通过温通治愈，因热邪引起的通过泻下治愈，因寒邪引起的通过熨贴热敷治愈。凡是患上香港脚的，应当迅速进行针灸治疗，只用汤药淋洗的，是医生的大禁忌。观察香港脚的发生，都是由肾气虚弱而生成的，然而女性也有患香港脚的，必定是因为血海空虚。男女都应当顺应四时变化进行滋补，否则气血日渐衰弱，必然导致每年遇到蒸热天气时就发作，这是理所当然的。治疗方法大概没有超出这个范围。另外应当在四季之中，适当加以调养摄生。不得久坐久立在寒冷潮湿的地方，暑天也不应当在露天的湿处坐卧，能谨慎做到这些，根据法则随证候治疗，没有不痊愈的。
又论述：关于香港脚这个病，古人命名不一，今人称之为香港脚。男子得此病，受病在于肾；女子得此病，受病在于血海。寒暑风湿，愤怒悲伤，都能导致此病。香港脚的症状，有轻有重，有干性有湿性，有阴证有阳证，有虚证有实证，应当顺应四时变化，每年遇到蒸热天气就迅速发作。此外，更适宜进行针刺和艾灸，若使用汤药淋洗的，是医生的大禁忌。后方的药物随证候参考使用，没有不痊愈的。

*Qianjin Fang* states: Hongjiaojiao (Hong Kong foot / gouty arthritis) is caused by contracting wind-toxin. Furthermore, medical classics state: The cold, heat, wind, and dampness of the earth all transform into vapors. Since the feet constantly tread upon them, Hongjiaojiao thus forms. However, although the explanations differ, the essence is the same. From this perspective, cold, heat, wind, and dampness can all cause this disease, not merely wind-toxin. The disease of Hongjiaojiao initially presents without noticeable symptoms; it may only manifest due to other illnesses, or suddenly cause severe oppression and confusion, becoming apparent only after two or three days. Symptoms start from the feet: they may present as slow weakness, pain, and numbness; sudden collapse while walking; swelling and fullness in both calves; withered and thin feet and knees; palpitations in the heart; insensitivity in the lower abdomen; generalized muscle spasms; vomiting and nausea upon seeing food, aversion to the smell of food; chest fullness and rapid breathing; or generalized body soreness and pain. These are the different manifestations of the condition. Generally speaking, if cold invades the Yang meridians, the illness will necessarily be cold in nature; if summer-heat invades the Yin meridians, the illness will necessarily be hot in nature. This statement is indeed true. Regarding pulse diagnosis: if the pulse is floating and wiry, the origin is wind; if soggy and weak, the origin is dampness; if surging and rapid, the origin is heat; if slow and choppy, the origin is cold. Wind-origin cases are cured by inducing sweating; damp-origin cases by warming; heat-origin cases by purging/downward draining; cold-origin cases by hot compresses/ironing. Whenever Hongjiaojiao is contracted, acupuncture and moxibustion should be employed promptly. Using only herbal decoctions for washing is a major prohibition for physicians. Observing the etiology of Hongjiaojiao, it arises from Kidney Qi deficiency. However, women also suffer from Hongjiaojiao, which must be due to Blood Sea (Chong and Ren vessels) deficiency. Both men and women should tonify according to the four seasons; otherwise, Qi and Blood will decline daily, inevitably causing recurrence every year during steaming-hot weather, which is logically inevitable. Treatment methods generally do not exceed these principles. Additionally, one must adjust and regulate lifestyle according to the four seasons. One must not sit or stand for long periods in cold and damp places, nor sit outdoors in damp areas during summer months. If one can be cautious in these aspects and treat according to patterns following these principles, recovery is assured.
Another discussion: Regarding the disease named Hongjiaojiao, ancient people used various names, but modern people call it Hongjiaojiao. When men contract this disease, the pathology resides in the Kidney; when women contract it, the pathology resides in the Blood Sea. Cold, heat, wind, dampness, anger, and sorrow can all cause this disease. The symptoms of Hongjiaojiao vary in severity (light/heavy), type (dry/wet), nature (Yin/Yang), and constitution (deficiency/excess). One should follow the four seasons, and the disease will rapidly flare up annually during steaming-hot weather. Furthermore, acupuncture and moxibustion are highly recommended. Using herbal decoctions for washing is a major prohibition for physicians. Refer to the subsequent formulas based on specific patterns for treatment, and recovery is assured.
