The condition known as "Lanhou Dansha" (Rotting Throat with Red Rash) is not named in previous medical texts. Looking back to ancient records, the *Jingui Yaolue* (Essential Prescriptions of the Golden Cabinet) contains references to "Yang Du" (Yang Toxin), and Wang Shuhe proposed the concept of "Wen Du" (Warm Toxin). The clinical manifestations of these are extremely consistent with what is currently termed Dansha and Rotting Throat. This treatise advocates using Shengma Biejia Tang (Cinnamon Twig and Turtle Shell Decoction) and Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity) as primary treatments. This discusses pathogens invading the Yin and Yang meridians. The general principles of treatment do not originally instruct practitioners to rigidly adhere to fixed formulas; learners should comprehend the underlying logic through careful study.

Upon investigation, this condition often erupts during seasons characterized by miscellaneous pathogens (*Za Qi*) and excessive Yang pathogens. Its onset is sudden and violent, uncontrollable like thunderstorms and fierce winds, causing pallor and dismay. Witnesses are often stunned, tongue-tied, and flee in panic. This resembles the cases of latent pathogenic fire and toxicity described by Fei Boqiong in his discussion on smallpox, such as hidden pulses, cold extremities, profuse sweating, diarrhea, hiccups, and restlessness—all severe symptoms. In some instances, it spreads within a family, leading to death within days. Alas, how has its cruelty become so intense today? Cheng Jiaoqian stated: "In ancient times, smallpox was rare, and Warm Toxins were prevalent; nowadays, smallpox is common, and Warm Toxins are rare." Perhaps the widespread practice of inoculation prevents toxin release, or is it merely a natural convergence of cosmic influences? In *Wu Yi Hui Jiang* (Compilation of Wu Medical Discussions), Li Zu and others discussed the pathology and treatment in detail. They noted that "sudden cold causes fire to stagnate and internally ulcerate, while excessive dispersal intensifies the flame and increases rotting." These are indeed profound truths, unshakable and certain. However, this does not exceed the principle outlined in Miao's notes: "Treating the Lung and Stomach as the root, first dispersing then clearing."

Applying this therapeutic logic: if the pathogen is at the Wei (Defensive) level, Maxing Gan Shi Tang (Ephedra, Apricot Kernel, Licorice, and Gypsum Decoction) is inevitably indicated; if toxic fire invades the Ying (Nutritive) level, Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) should be selected. Just as Ye Tianshi followed Yu Jiayan’s proposal for aromatic orifice-opening and detoxification, using Zixue Dan (Purple Snow Pill), this method is indispensable. Yet, clinical flexibility lies in the masterful adaptation by the practitioner. Whether correct or not, those capable will discern. This is but a fragment of my limited insight, awaiting correction from experts. If further guidance can be provided to prevent harm to the people, I would be most grateful.

The ear is the opening of the Kidney and the convergence point of the Shaoyang Gallbladder and Sanjiao (Triple Burner) meridians. Abscesses and ulcers here are caused by the rebellion of Fire from various meridians. However, one must distinguish between Deficient Fire and Excess Fire. If Wind-Warmth attacks and obstructs, initial symptoms include alternating chills and fever, headache, ear swelling, and a wiry, hard, rapid pulse, resembling malaria. One may use Niubangzi (Arctii Fructus), Jingjie (Schizonepetae Herba), Bohe (Menthae Haplocalycis Herba), Xiakucao (Prunellae Spica), Mudanpi (Moutan Cortex), Zhizi (Gardeniae Fructus), or Xiaochaihu Tang (Minor Bupleurum Decoction). If sweating occurs and the pathogen is thoroughly expelled, the swelling will subside naturally. If, after three to five days, distending pain worsens, accompanied by fever and discomfort, the Wind-Warmth transforms into Fire, likely carrying Liver pathogenic factors upward. The pain becomes stabbing, and pus forms internally. At this stage, Lingyangjiao (Capricornis Cornu), Mudanpi, Zhizi, Gouteng (Uncariae Ramulus cum Uncis), and Xiakucao may be used, or Longdan Xiegan Tang (Gentiana Liver-Draining Decoction). Once pus drains and the pathogen is cleared, fever subsides and pain stops. However, the pus will not dry immediately; healing takes ten to fifteen days because the Shaoyang Sanjiao is abundant in Qi but deficient in Blood; insufficient Blood makes muscle regeneration difficult, hence slow wound closure. This is an Excess Fire syndrome. Note that when pus is present in the ear, powdered medicines should not be applied directly. The ear canal has openings but no closing mechanism; inserting powder blocks the orifice, preventing pus drainage. Heat and toxicity then spread along the collaterals externally, causing redness and swelling around the ear, leading to an external ear abscess. Surgical incision for drainage is necessary for cure.

The so-called Deficient Fire Ear Abscess arises from suppressed anger-fire of the Liver and Gallbladder, or from depletion of True Yin in the Kidney meridian, leading to hyperactive Minister Fire. Initial symptoms include chills and fever, distension without swelling, pulling pain from the vertex to the neck, a fine and rapid pulse, and quiet mental/physical state. This is Liver Yang carrying Deficient Fire upward, which cannot dissipate and eventually forms pus. Such ulcers are difficult to heal quickly. Initially, Lingyangjiao San (Antelope Horn Powder) is used to settle the Liver and clear heat; for chronic cases, Dabu Yin Wan (Major Nourishing Yin Pill) or Jin Gui Shenqi Wan (Kidney Qi Pill from the Golden Cabinet) are used to nourish Yin and tonify deficiency. Additionally, children aged three or four may suffer from this condition with persistent pus for years. This is due to congenital insufficiency, where Water fails to nourish Wood, causing Liver Yang to rebel and knot. There is no pain or swelling, and no treatment is needed; it resolves when Yin is sufficient and Liver Yang stabilizes. Furthermore, infants may experience ear pain and pus due to fetal wind-heat or water entering the ear during bathing. Do not apply medication initially; wait for the toxin to resolve spontaneously. If unresolved after a month, treat with Hongmian San (Red Cotton Powder).

Ear Polyp (Er Jun): A small, skinless, red nodule resembling a mushroom grows in the ear canal. It does not suppurate nor cause chills/fever, but causes persistent ear blockage and deafness. First, puncture with a needle and apply Yuhong Gao (Jade Red Ointment). For ear distending pain, drip Hu'ercao (Dorstenia Genus Juice) into the ear to stop pain. Internal medication follows the same protocol as for Deficient Fire Ear Abscess.

Appendix: Ear Fistula (Er Lou) occurs above the ear root. It is common in girls who have pierced their ears and suffered injury. Suppurating wounds are difficult to close; one must use Sheng Yao Tiao (Arsenic-containing Paste Stick) to promote pus discharge and remove necrotic tissue over a long period for cure.
