香港脚始受于湿，复夹风、寒、暑、热之邪而成。故先起于腿足，必脚屈弱而举动转筋，
肢节疼而足 痛，小腹不仁，心中悸动，胸前便涩。但发热头痛、身疼之候绝似伤寒，人多
误治。仲景以香港脚类伤寒症，另立篇目以别之，盖为此也。罗谦甫云∶南北香港脚受病不同，
南方KT 湿，湿每袭虚而病起于下，此香港脚从外受也；北方地高无湿，共俗饮潼乳酒面，
以饮多快食为能，或奉养太过亦滋其湿，水性润下，气不能拘，故下注于足而成肿痛，此脚
气从内受也。当推究所因而治之。

香港脚（一种以足部肿痛、麻木为主要表现的疾病，俗称脚气）起初由湿邪侵袭所致，随后夹杂风、寒、暑、热等邪气而发病。因此，病症首先出现在腿足部位，必然出现脚部屈伸无力、行动时肌肉痉挛抽搐，肢体关节疼痛、足部疼痛，小腹感觉迟钝或麻木，心中悸动不安，胸部及小便处有涩滞感。虽然也有发热、头痛、身体疼痛的症状，这与伤寒病极为相似，人们常常误治。张仲景认为香港脚的症状类似伤寒，所以另立篇目加以区分，大概就是为了这个原因。罗谦甫说：南北方患香港脚的病因不同，南方气候潮湿，湿气容易侵袭人体虚弱之处且病起于下部，这是香港脚从外部感受邪气所致；北方地势高燥无湿气，当地风俗喜欢饮用浓稠的乳制品、酒类面食，以饮食量大、进食快为能事，或者过度滋补也会滋生湿气，水性润下，气机不能固摄，所以湿气向下注于足部而形成肿痛，这是脚气从内部感受邪气所致。应当推究其病因进行治疗。

Hongjiao (a disease characterized by swelling and pain in the feet, commonly known as "Jiaqi" or beriberi-like syndrome) initially arises from dampness pathogen invasion, subsequently complicated by wind, cold, summer-heat, and heat pathogens. Therefore, the symptoms first appear on the legs and feet, inevitably presenting with weakness in foot flexion and extension, muscle spasms during movement, pain in limb joints and feet, insensitivity in the lower abdomen, palpitations, and a sensation of stagnation in the chest and urethra. Although there are also symptoms of fever, headache, and body ache, which closely resemble Shanghan (Cold Damage), people often misdiagnose and mistreat it. Zhang Zhongjing considered Hongjiao symptoms similar to Shanghan, thus establishing separate chapters to distinguish them, likely for this reason. Luo Qianfu stated: The etiology of Hongjiao differs between the North and South. In the South, the climate is humid; dampness easily attacks deficient areas and diseases originate from below, meaning Hongjiao is contracted externally. In the North, the terrain is high and dry without dampness. Local customs favor drinking rich dairy products, wines, and noodles, regarding large intake and rapid eating as prowess. Or, excessive nourishment generates dampness internally. Since water nature is moistening and downward-flowing, Qi cannot restrain it, so dampness sinks to the feet causing swelling and pain; this means Jiaqi is contracted internally. One must investigate the cause and treat accordingly.
Hongjiao Ascending Attack (formation of swollen nodules and all kinds of swelling/toxins):
Apply Gan Sui powder (Kansui Root) mixed with water topically; take Gan Cao juice (Licorice Decoction) orally to eliminate it. (From *Bai Yi Xuan Fang*)
Damp Hongjiao (foot pain, calf swelling, must consume Fang Ji Yin):
Bai Zhu (Stir-fried Atractylodis Macrocephalae Rhizoma), Xi Jiao (Rhinoceros Horn - *Note: Substitute with Buffalo Horn in modern practice*), Cang Zhu (Stir-fried Atractylodis Rhizoma), Sheng Di (Wine-fried Rehmanniae Radix), Huang Bo (Wine-fried Phellodendri Cortex), Mu Tong (Akebiae Caulis), Fang Ji (Stephaniae Tetrandrae Radix), Bing Lang (Arecae Semen), Chuan Xiong (Ligustici Chuanxiong Rhizoma) each 8 fen; Gan Cao Shao (Terminal part of Licorice Root) 7 fen.
Decoct in water and take hot. If heat signs are present, add Huang Qin (Scutellariae Radix); if heat is severe or during hot weather, add Shi Gao (Gypsum Fibrosum); if phlegm is present, add Zhu Li (Bambusae Sap) and Jiang Zhi (Zingiberis Recens Juice) or Nan Xing (Arisomatis Rhizoma); if constipation, add Tao Ren (Persicae Semen); if urination is difficult/stagnant, add Niu Xi (Achyranthis Bidentatae Radix). (From *Mi Fang Ji Yan*)
Leg Spasm (spasms ascending into the abdomen):
Immediately use Mu Gua (Chaenomeles Fruit) and Wu Zhu Yu (Evodiae Fructus) each 1 qian, Yan Shi (Halite) 5 fen, decoct in two zhan of water until half remains. Take orally to be cured. If not treated urgently, pain rushing to the heart will be incurable. (From *Yuan Ti Ji*)
Cang Zhu San (Treats all pains in feet, knees, waist, buttocks, and thighs caused by wind-cold-damp-heat, and Hongjiao, highly effective):
Cang Zhu (Soaked in rice wash water for one day and night, stir-fried with salt) and Huang Bo (Remove coarse bark, soaked in wine for one day and night, roasted until scorched) each 5 qian.
Take as one dose, decoct in two zhong of water until half remains. Take before meals, two to three times daily. (From *Yi Fang Xuan Yao*)
Foot and Knee Pain (causing inability to walk):
Shan Zha Rou (Hawthorn Flesh) and Bai Ji Li (Tribuli Fructus) in equal parts. Steam twice and sun-dry twice, then grind into powder. Form pills with honey the size of Sophora seeds. Take 3 qian per dose, swallow with warm water. Whether taking one jin or two jins, all will be cured. (Copied by Zhou)
Foot Callus Pain:
When walking long distances urgently, stepping on stones causes sole swelling and inability to walk, unbearable pain. Urgently soak old straw sandals in a urine bucket overnight. Heat a new brick red-hot, place the wet sandal on the brick, then step the swollen foot onto it. Use fire to force the urine vapor into the body; swelling will subside. If not treated early, it may ulcerate and become hard to heal.
Yi Li Jin (Treats wind, cold, summer-heat, dampness causing all wandering pains, regardless of distance, unbearable pain):
Bai Jiao Xiang (Elemi Resin, ground separately), Cao Wu (Aconiti Kusnezoffii Radix, peeled and navel removed), Wu Ling Zhi (Trogopterori Faeces), Di Long (Pheretima, cleaned of soil), Mu Bie Zi (Semen Strychni, pounded to remove oil) each 1 liang 5 qian; Ru Xiang (Olibanum), Mo Yao (Myrrha), Dang Gui (Angelicae Sinensis Radix) each 7 qian 5 fen; She Xiang (Musk) 2 qian 2 fen; Jing Mo (Beijing Ink, burned until smokeless) 1 qian 2 fen.
Mix with glutinous rice flour to form pills the size of Euryale Seed. At onset, take one pill dissolved in wine on an empty stomach. The medicinal effect reaches the foot surface; if redness and swelling persist, take another pill. The effect reaches the sole; black sweat discharges, rooting out the disease. If the disease is in the upper body, take with wine after meals and before bed, natural sweating will occur. For stroke paralysis, numbness, loss of motor control, hemiplegia, take two pills with wine, three times daily. For sudden coma/fainting, grind one pill, mix with wine, and administer; upon waking, feet will feel hot. (From *Wan Bing Hui Chun*)
Foot Affection (Treats dampness, pain in both legs):
Ai Ye (Artemisiae Argyi Folium) 2 liang, Cong Tou (Scallion Bulb) one bunch, pound into paste. Sheng Jiang (Zingiberis Rhizoma Recens) 1 liang 5 qian, also pound into paste. Wrap together in cloth, dip in extremely hot Sha Jiu (Baijiu/Liquor), and rub the affected area until pain stops. (Secret Recipe Copy)
Sole Swelling and Pain (Caused by prolonged walking/standing):

Toe Web Ulcer:
Bake E Zhang Huang Pi (Skin of Goose Palm/Yellow Skin) until dry, burn to ash retaining its nature, grind into powder and apply. Or, ulcers caused by scratching due to summer heat: chew fine tea until pasty and apply. (Single Formula)

Mix with raw Chicken Egg White, make into a plaster separated by paper for application. (From *Huai De Tang Fang*)

Alternative: Pear leaves 100 pieces, pig lard 2 liang. Stir-fry leaves in pot, then add good white beeswax 2 liang, pound and mix until melted into the medicine. Add salt 1 liang, mix well.
