One qian, mixed with Doulin Jiu (Soybean Dripping Wine) for oral administration; simultaneously, wash the feet with a decoction of Chuanjiao (Zanthoxylum Bungeanum Fruit), Xiangbaizhi (Angelica Dahurica Root), and Caowu (Aconitum Carmichaelii Lateral Root). For Hongxiangjiao (Gouty Arthritis/Foot Qi) presenting with hidden pain and difficulty in walking, Pingwei San (Calm the Stomach Powder) combined with Chiqu (Red Fermented Rice) and decocted together is most effective; Jiming San (Rooster Crow Decoction) is also excellent. For Hongxiangjiao with stagnation (Yong), use Jiabian Binglang Tang (Modified Areca Seed Decoction). For cases without stagnation, use Niuxi Tang (Achyranthes Root Decoction), composed of Chuanniuxi (Achyranthes Bidentata Root, washed with wine), Baifuling (Poria Cocos, peeled), Renshen (Ginseng Root, de-gubbed) each at one liang, and Danggui (Angelica Sinensis Root, de-gubbed) at half a liang, ground into fine powder. Take three qian per dose, administered orally with warm wine on an empty stomach. When Hongxiangjiao causes swelling and fullness in both calves, it is termed a disease of stagnation (Yong), common in the South, where both feet become enlarged and persist until old age. In the initial stage, heavy doses should be used to unblock stagnation, or bi-stone therapy should be employed to drain evil blood and remove severe pathogenic factors, followed by herbal treatment. The Classics state: "Accumulation leads to swelling and heat; treat with bi-stone puncture."

[Washing] The *Huoren Shu* (Book of Living People) states: "For any case of Jiaoqi (Foot Qi/Gout), taking tonifying medicines and using hot water washing are major taboos among physicians." This warning applies to cases in the South where external dampness invades the body due to deficiency, causing swelling and pain, not to cases in the North where internal dampness descends, causing swelling and pain. Generally, if dampness cannot diffuse outward, it is appropriate to use washing to guide and open the pathways, draining and venting the pathogen, named Daoqi Chushi Tang (Guide Qi and Remove Dampness Decoction).

The *Waitai Miyao* (Essential Prescriptions Worth a Thousand Gold for Emergencies) states: "First, avoid anger; anger causes mental agitation, which triggers Hongxiangjiao. Second, forbid loud talking; loud talking damages the Lung, and Lung damage also induces the disease. Do not expose the feet; do not sit in the wind, enter water, or wash feet with cold water. The calves especially must not be kept cold. Even in summer, cotton pants should always be worn. In winter, keep the calves extra warm. Obtaining slight sweating is highly beneficial. Following these regimens, the pathogenic qi gradually diminishes. On days corresponding to Yin and Chou, trim the fingernails and toenails slightly penetrating the flesh to expel qi. In summer, when pores are open, do not sleep facing the wind. Upon waking, have someone massage acupoints to prevent pathogenic qi from lingering. Frequently move the joints to maintain patency. These are essential for health preservation and resisting wind pathogens. Those with normal strength should walk 300-500 steps after each meal, stopping when tired. The evil qi in the feet will then dissipate downward, preventing even edema from rising. In treating this disease, eat freely and fully for breakfast every morning, eat less for lunch, and fasting for dinner is best. One must fear damaging the Spleen and Stomach's transporting and transforming qi, losing natural rhythm. Moreover, night eating causes blood and qi stagnation, increasing swelling and pain in the Yin channels. First, do not overconsume alcohol and dairy products (Tongluo); excess damages the Spleen and Stomach, leading to downward pouring into the calves and dorsum of the feet, resulting in foot diseases. Second, do not indulge in sexual desires; excessive lust triggers Hongxiangjiao. After meals, walk slowly for 200-300 steps, stopping before sweating or feeling fatigued; thus, stagnation will not form. The Classics say: 'Move those who are sedentary.' It also says: 'In cases of damp Bi syndrome, avoid warm/heavy foods and wet clothing.'"

[Diagnosis] A floating and wiry pulse indicates deficiency; a soggy and fine pulse indicates dampness; a surging and rapid pulse indicates heat; a slow and choppy pulse indicates cold; a faint and slippery pulse indicates deficiency; a deep, firm, and hard pulse indicates excess. Floating pulses indicate exterior conditions; sinking pulses indicate interior conditions. Deep and wiry indicates Wind; deep and tight indicates Cold; deep and fine indicates Dampness; deep and rapid indicates Heat. Knotted pulses arise from Qi stagnation; scattered pulses arise from Worry; tight pulses arise from Anger; fine pulses arise from Grief. If the pathogen enters the Heart, there is mental confusion and delirium, vomiting with inability to retain food, and restless sleep. If the left Cun pulse fluctuates between large, small, and absent, it is untreatable. If the pathogen enters the Kidney, both waist and feet swell, urination is obstructed, groaning occurs, the mouth and forehead turn black, chest distension with wheezing appears, and if the left Chi pulse is absent, it is untreatable. If one observes urgency below the heart, ceaseless wheezing, frequent spontaneous sweating, alternating chills and fever, a hurried, short, and rapid pulse, and ceaseless vomiting, death ensues.
