论述说：中原地区地势平坦且潮湿，符合土的特性，能够化生万物。因此中国的人饮食繁杂而缺乏劳作，所以容易患痿证和厥证。遇到疾病时，气血需要顺应四时的变化，唯独在冬季禁止进行按摩导引（按跷），这是因为不想扰动阳气的原因。
治疗香港脚（足部肿痛）及四肢风邪引起的症状。应当先存神静气，正身端坐，伸直双腿站立，脚趾朝上，双手伸展与足趾对齐，慢慢触及足心。如果身体肥胖，手无法触及足部，可以用两条棉绳。
如果刚开始感觉患有香港脚，可以艾灸风市穴、足三里穴各二十一壮，以泻除风湿毒气。如果觉得闷热，千万不要艾灸，因为体内本有热，艾灸则会大大助长热势。
取穴方法：风市穴，让病人平身直立，双手下垂贴于大腿两侧，中指尖头所指处即是穴位。三里穴（足三里），让病人膝盖下三寸，胫骨外侧，按压时有轻微凹陷感的地方即是穴位。另一种方法是用手指深按，如果足背动脉（趺阳脉）搏动消失的为准。
郭都官长期患有香港脚，发作时出现寒热、胀满、气逆上冲的症状，服用热性药物后病情加重。兆（医生名）用《外台秘要》中的延年茯苓饮来降其气，再用六物麻子丸来泄其热。后来再次见到他，只是还苦于燥热，于是让他服用紫雪，效果显著。
少府监韩正彦患病，手足不能抬起，众医都认为是中风，对臂腿进行针刺。兆却说：“这是香港脚。”让他服用此汤药，于是痊愈。

Discourse states: The Central Region is flat and damp, conforming to the virtue of Earth, and generates all things. Therefore, people in China have a varied diet but lack physical labor, making them prone to Wei syndrome (flaccidity syndrome) and Jue syndrome (cold extremities). When illness occurs, Qi and Blood must adapt to the four seasons; specifically, Anqiao (massage and stretching exercises) are prohibited in winter because one wishes not to disturb Yang Qi.
Treatment for Hongjiaojiao (Gouty arthritis / Foot swelling and pain) and wind pathogens affecting the four limbs. One should first calm the mind, sit upright, extend both legs while standing, point toes upward, stretch hands to align with toe tips, and gradually reach the soles of the feet. If obese and hands cannot reach the feet, use two cotton ropes.
If Hongjiaojiao is just beginning, moxa points Fengshi (GB31) and Zusanli (ST36), 21 moxa cones each, to drain wind-dampness and toxic vapors. If feeling stifling heat, do not moxa, as internal heat already exists, and moxa would greatly exacerbate it.
Acupoint location method: For Fengshi point, let the patient stand upright with arms hanging down along the thighs; the tip of the middle finger indicates the point. For Zusanli point, three cun below the knee on the lateral side of the tibia, where slight depression is felt upon pressure, is the point. Another method: press deeply with a finger until the foot Yangming pulse (Duyang pulse) disappears; this serves as the standard.
Guo Duguan suffered from chronic Hongjiaojiao. Upon onset, he experienced chills, fever, distension, fullness, and rebellious Qi. Taking hot-natured medicines worsened his condition. Zhao used Yan Nian Fuling Yin (Longevity Poria Decoction) from *Waitai Miyao* to direct Qi downward, followed by Liuwu Maziren Wan (Six-Ingredient Hemp Seed Pill) to drain heat. Upon subsequent visit, he still suffered from dryness and heat, so Zhao prescribed Zixue (Purple Snow), which yielded excellent results.
Han Zhengyan, Shaofu Jian, suffered from inability to move his hands and feet. All physicians diagnosed it as Zhongfeng (Wind Stroke) and needled his arms and legs. Zhao said, "This is Hongjiaojiao." He administered this decoction, and the patient recovered.

Bu Shu Hao Zhi suffered from Hongjiaojiao with swelling, fullness, and ulceration. Someone treated it as Shuiqi (water qi/edema disease), using purgative medicines. He had bowel movements three times a day for over fifty times, after which the foot swelling subsided. Later, he occasionally experienced heart and abdominal discomfort...
