The history of the Southern Dynasties records that Fan Yun, initially an official under Emperor Wu of Chen, suddenly contracted Shanghan disease (Cold Damage) when the Emperor was about to receive the Nine Bestowals. Fearing he could not attend the celebration, he summoned Xu Wenbo for diagnosis and sincerely asked, "Can I recover quickly?" Xu Wenbo replied, "Recovering quickly is very easy, but I fear you will not rise again in two years." Fan Yun said, "If I hear the Dao in the morning, I can die content in the evening; how much more so for two years?" Xu Wenbo heated the ground with fire, spread peach leaves, set up a mat, and placed Fan Yun upon it. In an instant, sweat emerged and the condition resolved; he was wrapped in warm powder and healed the next day. Fan Yun was very pleased, but Xu Wenbo said, "There is no need to be pleased." Two years later, he indeed passed away. This shows that inducing sweating prematurely still shortens life expectancy; how much more so to disregard the exterior and interior patterns and seek rapid results without waiting for the appropriate time? I often see patients who cannot endure treatment; if doctors urge sweating day and night within three or four days, complying with the patient's wishes, few do not fail. Therefore, I write this as a warning for physicians. (From *Benshi Fang*)

A commoner in Lin'an suffered from Shanghan disease with his tongue protruding over one inch, for which no cure was found. Porridge was administered through a brush tube into his mouth daily. He sat at the gate every day. A Daoist priest saw him and sighed, saying, "I can cure this instantly, but alas, I have no medicine." The family heard this and requested, "If money can procure it, we will strive to find it." The priest refused to reveal the remedy and left. The next day, the matter was raised again. Ten days later, a noble official returned from duty, dismounted, and observed the patient. The priest happened to arrive and repeated his previous words. The official asked what medicine was needed. The priest replied, "Meihua Pian Nao (Plum Blossom Borneol)." Laughing, he said, "This is not difficult." He immediately sent a servant to fetch it swiftly and handed it to the priest. The priest powdered it and applied it to the tongue; the tongue retracted immediately. Five qian were used, and the illness was cured instantly. (From *Ding Zhi*)

*Zhou Li · Tian Guan Xia* states: The Physician-in-Charge is responsible for nurturing the people and treating their diseases. There are pestilential diseases in all four seasons: in spring, there is Shou Ji (Headache); in summer, Yang Jie Ji (Itching and Scabies); in autumn, Nuè Han Ji (Malaria-like Chills); in winter, Sou Shang Qi Ji (Cough and Rebellious Qi).

Sha Bing (Sand Disease) did not exist in the Jiangnan region in the past but is now present everywhere. Tracing its manifestations, medical texts do not record them in detail. Generally, the patient feels chills similar to Shanghan but resembles malaria, experiencing headache, high fever throughout the body, and cold extremities. Rural areas mostly use Moxibustion, considering the appearance of "Sha" (petechiae or pustules) favorable. Some died after pus and blood gushed out from moxibustion wounds, which is truly pitiable. Yong Chengjie printed this prescription stating: Upon initial onset, drinking Mugwort Decoction to induce vomiting confirms the diagnosis if Sha is present. Quickly take a piece of paper made from silkworm pupae shed in May, tear it into pieces, place it in a bowl, cover tightly with a plate, soak in hot water for about half a bowl, seal the edges with paper to prevent air leakage. After a while, drink it while hot, lie down, cover with thick clothes and blankets to induce profuse sweating, and the illness will resolve. Is this not superior to using fire moxibustion and causing unnecessary harm to human life? Respect and believe in it. (From *Ye Shi Lu Yan Fang*)
