论述说：《内经》提到南方地区，地势低洼，水土柔弱，是雾气和露水聚集的地方。江东和岭南地区大体上都是这样。在春夏交替之际，山水之间热气蒸腾郁结，风湿毒气非常严重。足部如果感受了这种邪气，就会形成瘴毒香港脚（一种因湿热毒邪引起的下肢疾病）。其症状表现为脚部先出现屈伸不利、软弱无力，逐渐发展到麻木疼痛，膝盖和小腿轻微肿胀，小腹部感觉迟钝或麻木，头痛心烦，痰液壅盛、呕吐逆气，时而发冷发热，大小便不通畅。病情严重的会攻冲心脏，形势危急，治疗确实不可迟缓。支法存之所以留意经方并擅长此术，难道不是因为江东岭表地区，患此病的人很多吗？

Commentary states: The *Neijing* (Inner Canon) mentions that the southern regions are low-lying, with weak water and soil conditions, and are places where fog and dew gather. The Jiangdong and Lingnan areas are generally like this. During the transition between spring and summer, heat and moisture from mountains and rivers steam and stagnate, making wind-dampness toxic gases very severe. If the feet are affected by these pathogens, it leads to "Zhangdu Hong Kong Foot" (a lower limb disease caused by damp-heat and toxic pathogens). The symptoms present as initial weakness and difficulty in flexing the feet, gradually progressing to numbness and pain, slight swelling of the knees and shins, insensitivity or numbness in the lower abdomen, headache, irritability, phlegm obstruction, vomiting and regurgitation, alternating chills and fever, and obstruction of urination and defecation. In severe cases, the pathogen attacks the heart, creating a critical situation; treatment must indeed not be delayed. Zhi Fazcun paid attention to classical prescriptions and excelled in this technique, was it not because this disease was prevalent in the Jiangzuo and Lingnan regions?
For treating Hong Kong Foot in the Jiangdong region, where slight movement causes chest stuffiness, soreness and pain in the calves, and incessant irritability and heat, use the Xijiao Tang (Rhinoceros Horn Decoction):
Xijiao (Rhinoceros Horn, sliced) 1 liang, Muxiang (Costus Root) 1 liang, Qianhu (Peucedani Radix, de-radicle) 1 liang, Qingzhuru (Green Bamboo Shavings) 3 fen, Maimendong (Ophiopogonis Tuber, de-core) 1.5 liang, Dafu (Arecae Pericarpium, 3 pieces, chopped with peel).
The above six herbs are coarsely crushed and sifted. Take 5 qianbi per dose, decoct in 1.5 zhan of water until 1 zhan remains, strain, and take at any time.
For treating the onset of Hong Kong Foot in the Jiangdong region, characterized by vertigo, expectoration of phlegm, chest stuffiness, qi stagnation, nausea upon seeing food, and tightness/pain in the epigastrium, use the Xuanfuhua Tang (Inula Flower Decoction):
Xuanfuhua (Inulae Flos) 1 liang, Chi Fuling (Poria Cocos with Black Skin Removed), Sangbaipipi (Mori Cortex), Banxia (Pinelliae Rhizoma, soaked in water seven times to remove slipperiness), Zisujing (Perillae Caulis), each 2 liang.
The above six herbs are coarsely crushed and sifted. Take 5 qianbi per dose, decoct with 1.5 zhan of water and 2 halved Jujubae Fructus until 1 zhan remains, strain, add 1 he of Shengjiangzhi (Ginger Juice), and take on an empty stomach. To promote purgation, add 2 qianbi of Binglangmo (Arecae Semen Pulverized) after the decoction is ready.
For treating Hong Kong Foot already developed in the Jiangdong region, complicated by chronic cold qi rushing upward causing heart vexation and pain, constipation, abdominal distension like a drum, and gradual mental confusion, use the Wuzhuyu Tang (Evodiae Fructus Decoction):
Wuzhuyu (Evodiae Fructus, soaked in water, roasted) 1 liang 1 fen, Muxiang (Costus Root) 2 liang, Nongpu (Magnoliae Officinalis Cortex, bark removed, stir-fried with ginger juice) 2 liang, Dafu (Arecae Pericarpium, chopped with peel) 5 pieces, Qianniuzi (Semen Koelpiniae) [quantity implied in method].
Except for Qianniuzi, the above five herbs are coarsely crushed and sifted. Take 3 qianbi per dose, decoct with 1.5 zhan of water and 1 fen of smashed Shengjiang (Fresh Ginger) until 0.7 zhan remains, strain, add 1 qianbi of Qianniuzimo (Semen Koelpiniae Pulverized), mix well, and take on an empty stomach. Stop when urination and defecation become unobstructed.
For treating severe onset of Hong Kong Foot in the Jiangdong region, characterized by bilateral foot edema, red and scanty urine, chest and abdominal fullness, shortness of breath preventing sitting or lying down, use the Fuling Tang (Poria Decoction):
Chi Fuling (Poria Cocos with Skin Removed), Sangbaipipi (Mori Cortex, chopped), Fangji (Stephaniae Tetrandrae Radix), Muxiang (Costus Root), Huangqin (Scutellariae Radix, de-black heart), Yuliren (Pruni Semen), each 3 liang. [Note: Text lists eight items but quantities may vary].
The above eight herbs are coarsely crushed and sifted. Take 5 qianbi per dose, decoct with 1.5 zhan of water and 1 fen of smashed Shengjiang (Fresh Ginger) until 0.7 zhan remains, strain, and take before morning and evening meals.
For treating severe onset of Hong Kong Foot in the Jiangdong region, where pathogens rush upward affecting the spleen and stomach, causing chest and diaphragm stuffiness, ineffective belching, irritability, dry mouth, blurred vision, and inability to recognize people, use the Lingyangjiao Tang (Saiga Antelope Horn Decoction):
Lingyangjiao (Saigae Tataricae Cornu, sliced) 1.5 liang, Xijiao (Rhinoceros Horn, sliced) 1.5 liang, Shengma (Cimicifugae Rhizoma) 1 liang, Xuanfuhua (Inulae Flos) 1 liang, Muxiang (Costus Root) 1 liang, Dafu (Arecae Pericarpium, 5 pieces, chopped with peel).
The above nine herbs are coarsely crushed and sifted. Take 5 qianbi per dose, decoct in 1.5 zhan of water until 1 zhan remains, strain, and take on an empty stomach. Stop when bowel movements are smooth.
After taking the previous Lingyangjiao Tang, if loose stools occur but slight heat remains, qi rebels causing vomiting, inability to eat, phlegm in the chest and diaphragm, and a constant feeling of emptiness in the abdomen, use the Dafu Tang (Arecae Pericarpium Decoction):
