See the section "Example of Different Origins of Hot Diseases."

*Waitai Miyao* states: The first taboo is anger; anger causes mental restlessness, and mental restlessness triggers Hongjiaojiao (Gouty Arthritis). One must also avoid speaking loudly, as loud speech damages the Lung (Lung), and lung damage can also induce the disease. One should not expose the feet to wind or immerse them in water, nor wash the feet with cold water; especially, the calves are particularly unsuitable for cold exposure. Even during hot summer months, one should constantly wear silk floss garments; in winter cold, one must doubly ensure the warmth of the calves, with slight sweating being ideal. Based on these principles, regulate one's lifestyle so that qi gradually becomes thin and reduced. On every Yin and Chou days, trim the fingernails and toenails slightly into the flesh to expel pathogenic qi. In summer, when the cou li (pores/skin texture) are open, one should not sleep facing the wind. Upon waking from sleep, have someone massage and knead the body to prevent pathogenic qi from lingering. Frequently move the joints to keep them unobstructed; this is the essence of health preservation and a method to repel wind pathogens. Those with sufficient strength should walk three to five hundred steps after each meal and stop when tired; the evil qi in the feet will then dissipate downward, and even if edema occurs, the qi will not ascend.

*Mingyi Bielu* states: First, do not consume alcohol and dairy products (such as camel milk/cheese) excessively; excess damages the Spleen and Stomach, causing dampness to sink to the lower legs, resulting in swelling and forming Hongjiaojiao. Second, sexual desire should not be unrestrained; excessive lust induces Hongjiaojiao. After eating, one should walk slowly, as described above. The *Classic* says: "For those who are idle/languid, promote movement." It also says: "When the disease is in the Spleen, avoid warm foods, overeating, and wearing damp clothes."

Yang Taishou said: Since ancient times, the treatment of Hongjiaojiao has favored methods of draining and purging, because it is a disease of obstruction. However, one must not purge too heavily, as this damages the Spleen and Stomach, preventing the transporting and transforming qi from ascending, causing it to sink instead and become Hongjiaojiao. Conversely, one must not purge insufficiently, as this fails to resolve the qi obstruction. I now present three formulas below to be used according to detailed differentiation of deficiency and excess. According to *Mingyi Bielu*, these correspond to Daozhi Tang (Stagnation-Resolving Decoction), Daoyin Wan (Guiding and Leading Pill), and Chushi Dan (Dampness-Expelling Pellet). However, these are merely general examples. For instance, if Hongjiaojiao is at the exterior or involves the blood and qi levels, can the method of draining and purging be applied by analogy?

*Heren Shu* states: Taking tonifying medicines or using decoctions for washing/bathing in cases of Hongjiaojiao are major taboos for physicians. *Mingyi Bielu* clarifies that this prohibition applies to cases where external damp-heat invades due to deficiency, causing swelling and pain (typical of the South), rather than cases where internal dampness sinks downward causing swelling and pain (typical of the North). Since the dampness cannot reach the exterior, it is appropriate to use bathing and flushing to open, guide, and vent the pathogen.

Yang Taishou said: Hongjiaojiao is a disease of obstruction; treatment should employ agents that promote diffusion and unblocking to prevent qi from becoming obstructed. If obstruction has formed and is severe, one should use bian stone (stone lancet) to puncture and evacuate bad blood to remove the intense pathological condition. The *Classic* states: "Accumulation leads to swelling and heat; treat with bian stone." Subsequently, treat with herbal medicine.
