This disease is caused by deficiency of Qi in the Lung and Kidney, with pathogenic Wind-Cold invading. It leads to swelling of the chin and jaw, obstruction of the throat, inability to swallow liquids or medicines, and death may occur within moments. In such emergencies, urgently administer Huangyaozi San (Yellow Medicament Powder) to induce vomiting of foul phlegm, after which the patient will recover. For mild cases, treat the Lung by administering Jiangfu Tang (Ginger and Aconite Decoction); moxibustion on Tiantu (CV-22) for fifty moxa cones is also effective. For severe cases, administer Zhongru Fen (Stalactite Powder), moxa Guanyuan (CV-4), and also administer Jiangfu Tang.

Clinical Records:
One patient suffered from Hou Bi (Sore Throat/Obstruction), with Phlegm-Qi attacking upward, causing throat obstruction. After moxibustion on Tiantu (CV-22) for fifty cones, he was able to consume porridge. Subsequently, taking one dose of Jiangfu Tang (Ginger and Aconite Decoction) led to complete recovery. This illustrates treatment targeting the Lung.

Another patient suffered from Hou Bi (Sore Throat/Obstruction), with coarse swelling of the chin and jaw, inability to swallow porridge or medicine, cold limbs, and deep, fine pulses in all six positions. Emergency moxibustion on Guanyuan (CV-4) for two hundred cones warmed the limbs, and the pulses gradually returned. However, the throat remained swollen. He was instructed to take Huangyaozi San (Yellow Medicament Powder), and after vomiting one he of thick phlegm, he recovered. This illustrates treatment targeting the Kidney.

Another patient suffered from Hou Bi (Sore Throat/Obstruction) with fine pulses. I moxaed Guanyuan (CV-4) for two hundred cones, and his pulses gradually returned. A physician stated, "This is a Heat syndrome; using fire therapy is like carrying firewood to save a fire." He then administered a dose of cooling herbs. Consequently, the pulses became deep again, and the throat swelling worsened. The physician, having exhausted his methods, used a sharp knife to puncture the swollen area, releasing one sheng of blood, after which the patient recovered. This condition contraindicates cooling herbs because Phlegm coagulates upon encountering Cold. Therefore, puncturing to release Lung blood caused the swelling to subside.

(The Master's methods for treating the Lung and Kidney are outstanding insights of the ages. Moreover, among throat diseases, those caused by Wind-Fire account for only 20-30%, while those caused by Lung-Kidney Deficiency-Cold account for 80-90%. If throat specialists do not understand this principle and indiscriminately use cold-cooling herbs, even if external pathogens exist, they will become frozen and trapped. If the root Yuan Qi is depleted, closure and suffocation leading to death are inevitable. Thus, the best method for treating throat conditions is first to open and expel Phlegm-Saliva. Once the Phlegm-Saliva surges out, natural unblocking and comfort follow. Then, treatment should be applied based on severity. Jiangfu Tang (Ginger and Aconite Decoction) and burning moxa are indeed fundamental treatments, but people often fear them and refuse to use them. However, in critical situations, one must not avoid taboos; forced rescue can still lead to survival. Puncture therapy should also be understood. In the fourth year of Yongzheng, throat diseases were prevalent. A friend's son, Shen Liting, also suffered from Hou Bi (Sore Throat/Obstruction), which ulcerated the next day. I palpated his Cun positions (both left and right) as powerless and Chi positions (both left and right) as empty and scattered, diagnosing Yin Deficiency with Fire Hyperactivity. I prescribed Qiwai Wan (Seven-Ingredient Pill) prepared as a decoction. After one dose, symptoms did not diminish, but pain eased slightly. Neighbors insisted on consulting a throat specialist. That physician laughed at my frequent use of hot herbs, claiming this was a Yangming Excess-Heat syndrome where Fire nature is rapid, causing daily ulceration, and thus warm-tonifying agents should not be used. He administered Baihu Tang (White Tiger Decoction) for two doses. Before half was consumed, the patient's spirit changed abnormally, speech became confused, and he experienced insomnia and agitation. The family panicked and summoned me again. I palpated his pulse as chaotic, beating 8-9 times per breath. I said, "If it were truly Yangming Dryness-Fire, Shigao (Gypsum) would be an excellent agent. Now it is a Rootless Flame; recklessly using Baihu Tang has caused the Stomach collaterals to sink and fail to ascend, resulting in loss of Heart Spirit control." I administered Guipi Tang (Restore the Spleen Decoction) with added Guizhi (Cinnamon Twig). After just one dose, the spirit calmed and the pulse stabilized. Alas! Those throat specialists are unlearned individuals who rashly critique major prescriptions and indiscriminately administer herbal formulas, nearly killing patients through ignorance.)
