My cousin, Sun Zhongshu, a student at the Imperial Academy (Taixue), traveled to Nanjing (Nanyong) during the summer months. One day, after changing shifts, he came out to request tea. Upon drinking, the liquid flowed backward; it exited from his left nostril, with only three-tenths entering his stomach. At that time, all the renowned physicians in Baixia (Nanjing) who were attending him had been consulted. After nearly a month of conditioning, not only was this true for tea and water, but even porridge and rice were mostly expelled through the nose. Mr. Sun, by nature, valued cleanliness and refinement, associating daily with officials and scholars (Jinshen, Fengye). Consequently, he felt ashamed of his illness due to his status, took leave, and sought treatment. Hearing that Jingkou (Zhenjiang) had many famous doctors, he bought a boat to visit them. He visited doctors such as He, Zhang, and Tuan without exception. However, the more medicine he took, the worse his condition became. Nausea, dizziness, muscle wasting, and weakness in the four limbs gradually developed, and his heart grew increasingly anxious. He hurriedly returned home to seek my treatment. After completing my pulse diagnosis, I asked what symptoms the various renowned physicians had diagnosed and what prescriptions they had administered. Mr. Sun said: "All these gentlemen claimed that this disease is not recorded in medical texts and its treatment methods are unfounded, merely speculating it to be Stomach Fire (Wei Huo). They stated that all rebellious upward rushing belongs to Fire. Therefore, the prescribed formulas were either Huanglian Jiedu Tang (Coptis Decoction for Detoxification) or combinations involving Sanhuang Tang (Three Yellows Decoction), Shigao (Gypsum Fibrosum), Zhizi (Gardeniae Fructus), Huangbai (Phellodendri Cortex), Zhimu (Anemarrhenae Rhizoma), Tianhuafen (Trichosanthis Radix), and Gegen (Puerariae Lobatae Radix). Since I suffered from drinking wine upon arriving in Baixia, which might have stirred up fire, their reasoning seemed plausible, so I accepted their treatment without considering other plans." I said: "Treating disease requires distinguishing the meridians and their influx/outflow regarding deficiency and excess, clarifying Zang-Fu manifestations, observing meridian degrees, and thoroughly understanding the pathogenesis and pathology. This is why Bian Que could adapt to customs. How can one rigidly adhere to prescription books? The *Neijing* states: 'The pharynx is the pathway for water and grain; the larynx is where Qi ascends and descends; the nasopharynx (Hangsang) is where Qi diffuses.' When people suffer from rhinorrhea that does not stop, it is because the nasopharynx is not open. Your condition belongs to the category of nasopharyngeal obstruction. Because the nasopharynx is obstructed, Qi rushes upward instead of descending. The epiglottis is weak and cannot cover the glottis. Since the nose communicates with the airway, and because it is not covered, food and drink reverse and exit through the nasal orifice. Have you not seen that when ordinary people experience occasional Qi rebellion, food and drink are expelled via sneezing? This is the same example. Moreover, your right pulse is slow, weak, and powerless, clearly indicating Qi Deficiency (Qi Xu). The *Neijing* says: 'Cold affecting the body and cold drinks injure the Lung.' It also says: 'The Spleen and Stomach prefer warmth and dislike cold.' Furthermore: 'Clear vision and hearing require coolness; distinguishing odors requires warmth.' You have taken too many cold and cooling herbs, which is why you suffer from nausea, dizziness, and muscle wasting. I will only provide warming and tonifying treatment. The Lung belongs to Metal and governs Qi. When Metal Qi is vigorous, it converges and descends. When Qi descends, food and drink follow the Qi downward. I used Liujunzi Tang (Six Gentlemen Decoction) added with Xinyi (Magnolia Flower), Sangbaipi (Morus Cortex), Yiren (Coicis Semen), and Chenxiang (Aquilaria Lignum). After one dose, the severity eased; after three doses, it stopped for the most part; after seven doses, full recovery was achieved. Since this case was previously unrecorded, I write it down for future generations to reference."
