《诸病源候论》说：大凡香港脚病，都是由感受风毒所致。刚得这个病时，大多不会立刻察觉，或者之前没有其他的疾病，却突然患病。
苏敬论述说：这香港脚作为疾病，根本原因是肾虚，多侵袭肥胖且肌肤虚弱的人。无论男女，如果身体瘦弱且从事劳累辛苦的工作，肌肤薄弱……（原文此处有缺漏）
唐侍中论述说：大凡患香港脚病的人，大概是由于暑湿之气郁结积聚在体内，毒厉之风从外部吹袭逼迫所导致的。

《极要方》说：这病有好几种，有因饮水气下流而形成香港脚的，饮气即水气上冲；也有肾气先虚，在暑月用冷水洗脚，湿气不散；也有肾气既已虚弱，各种事情不加节制，因而居住在低洼潮湿之处，湿气上冲，也形成香港脚。
《诸病源候论》说：大凡香港脚，这病初起时非常轻微，饮食嬉戏，气力如故，应当仔细察验。其症状表现，从膝盖到脚，有不感觉知觉（不仁），或者像痹症，或者像虫行般流动（淫淫，流动的样子）沿着经络，或者脚趾及小腿发冷（洒洒，恶寒的样子）……（原文此处有缺漏）

The *Zhu Bing Yuan Hou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases) states: Generally, Hong Kong Foot disease (a term historically referring to beriberi or gout-like conditions in ancient texts, characterized by swelling and weakness of the legs) is caused by contracting Wind-Toxin. When first contracting this disease, one often does not immediately realize it; there may be no prior illness, yet suddenly the disease appears.

The *Ji Yao Fang* (Extremely Important Prescriptions) states: This disease has several types. There is Hong Kong Foot formed by drinking Qi flowing downward; Drinking Qi refers to Water Qi rushing upward. There is also Hong Kong Foot where Kidney Qi was previously deficient, and during summer months, feet were washed with cold water, causing Dampness not to dissipate. There is also Hong Kong Foot where Kidney Qi is already deficient, various activities are not regulated, and living in low, damp places causes Dampness to rush upward, also forming Hong Kong Foot.
The *Zhu Bing Yuan Hou Lun* states: Generally, regarding Hong Kong Foot, at the beginning of this disease, symptoms are very subtle. Diet, play, and physical strength remain as usual; one must examine it carefully. Its manifestations include numbness (Bu Ren) from the knees to the feet, or sensations resembling Bi Syndrome (Obstruction), or a crawling sensation like insects moving along the meridians (Yin Yin), or chills in the toes and calves (Sa Sa). ...

The *Ji Yao Fang* states: Hong Kong Foot causes everyone's calves to swell greatly, with heavy and stifling swelling on the dorsum of the feet. Severe cases rush upward to strike the Heart, with swelling, fullness, stifling sensation, and shortness of breath. Among them, there are two types of Dry and Wet Hong Kong Foot: Wet type features swollen feet; Dry type features non-swollen feet, gradually feeling dry and rough, with skin resembling fish scales (Jia Cuo). One must examine carefully.
