痹者，痛也，经云∶一阴一阳结，谓之喉痹。一阴者，手少阴心，一阳者，
手少阳三焦也。心为君火，三焦为相火，二火冲击，咽喉痹痛，法当散之、清之，加味甘桔
汤主之。又有非时暴寒，潜伏于少阴经，越旬日而后发，名曰伏气咽痛，谚云肾伤寒是已，
法当辛温以散之，半夏桂甘汤主之，复有少阴中寒之重证，寒客下焦，逼其无根失守之火，
发扬于上，遂致咽痛，其症手足厥冷，脉细沉，下利清谷，但用理中、四逆汤疗寒，而咽痛
自止。斯二者，寒也，其他悉属热证，不可不知。
咽喉肿痛胀塞，红丝缠绕，故名缠喉风，其症口吐涎沫，食物难入，甚则
肿达于外，头如蛇缠。先用黄齑汁调元明粉少许，灌喉中，搅去其痰，次用蜜水润之。
若齑汁不能拔痰，则用土牛膝，连根捣烂，和酸醋灌之。如或顽痰胶固，吐仍不出，咽
喉胀闭不通，滴水难入者，则用解毒雄黄丸，极酸醋磨下七丸，自然得吐而通。既通，可用
牛黄清心丸，加味甘桔汤。如或肿势达外，延及颈项头面，红如火光，药力难敌，急用瓷锋
砭去恶血，用鸡子清调乳香末润之，立瘥。或用芭蕉根汁润之，以解其毒。若口中肿胀紫黑
急用银针刺去其血，或用小刀点之，随以淡盐汤洗之，吹上冰片散。更有肿在喉里，针法
难施，急于手少商穴出血，则喉花自开，仍以解毒雄黄丸灌之，自然通透。此等病势危恶，非
吐痰、解毒、煎丸并进，刀针、砭石按法善施，解克有济也，治此者，平时揣摩纯熟，临症
庶能措手，幸毋轻忽怠缓以误人也。少商穴，在手大拇指内侧，去爪甲一韭叶许，针时，用
Bi (Obstruction) refers to pain. The *Neijing* states: "When one Yin and one Yang are knotted, it is called Hou Bi (Throat Obstruction)." By "one Yin," it refers to the Hand-Shaoyin Heart Meridian; by "one Yang," it refers to the Hand-Shaoyang Sanjiao (Triple Burner) Meridian. The Heart governs Jun Huo (Monarch Fire), and the Sanjiao governs Xiang Huo (Ministerial Fire). When these two fires clash and impact each other, they cause obstruction and pain in the throat. The treatment principle should be to disperse and clear the heat, primarily using Jiawei Ganjie Tang (Gan Jie Decoction with added herbs).
There is also a condition caused by sudden cold pathogens occurring out of season, which lie dormant in the Shaoyin Meridian and manifest after more than ten days. This is named Fuqi Yantong (Pharyngeal Pain due to Latent Qi), colloquially known as Shenshanghan (Cold Injury to the Kidney). The treatment principle should employ pungent-warm methods to disperse the pathogen, primarily using Banxia Guigan Tang (Banxia, Cinnamon Twig, and Licorice Decoction). Furthermore, there is a severe syndrome of Cold invading the Shaoyin Meridian, where Cold pathogens reside in the Lower Jiao, forcing the rootless and unanchored Fire to flare up towards the upper body, resulting in throat pain. Symptoms include cold extremities, a fine and deep pulse, and diarrhea with undigested food. In this case, simply using Lizhong Tang (Regulate the Middle Decoction) and Sini Tang (Reverse the Extremities Decoction) to treat the cold will naturally resolve the throat pain. These two scenarios belong to Cold syndromes, while others mostly belong to Heat syndromes; this distinction must not be overlooked.
Swelling, pain, and blockage in the throat and tonsils, accompanied by red filaments winding around, is thus named Chanhou Feng (Winding Throat Wind). Symptoms include spitting out saliva and froth, difficulty in swallowing food, and in severe cases, swelling extending externally so that the head feels as if wrapped by a snake. Initially, mix a small amount of Yuanming Fen (Refined Mirabilite) with Huangji Zhi (Juice of Yellow Pickled Vegetables) and instill it into the throat to stir up and remove phlegm, then moisten the throat with honey water. If the Huangji Zhi cannot extract the phlegm, use Tu Niuxi (Radix Achyranthis Bidentatae), crushed whole including the roots, mixed with sour vinegar for administration. If stubborn phlegm is firmly consolidated and cannot be expectorated, causing complete obstruction of the throat such that even a drop of water cannot pass, use Jiedu Xionghuang Wan (Detoxifying Realgar Pill). Grind seven pills with highly acidic vinegar and administer orally; vomiting will naturally occur, clearing the obstruction. Once cleared, Niuhuang Qingxin Wan (Calculus Bovis Heart-Clearing Pill) combined with Jiawei Ganjie Tang can be used. If the swelling extends externally to involve the neck, head, and face, appearing red like firelight, and medicinal power is insufficient to counteract it, urgently perform Bianci (Stone Needle Therapy) with a porcelain edge to release evil blood, then apply Ruxiang Mo (Frankincense Powder) mixed with Jizi Qing (Egg White) to moisturize; recovery will be immediate. Alternatively, use Bajiao Gen Zhi (Juice of Musa Basjoo Root) to moisten the throat and resolve toxicity. If the mouth swells with a purple-black color, urgently prick with silver needles to release blood, or puncture with a small knife, then wash with light salt water and insufflate Bingpian San (Borneol Powder). In cases where swelling is inside the throat where needle application is difficult, urgently bleed at Shaoshang (LU-11) Acupoint on the hand; the throat swelling will naturally open. Follow this by administering Jiedu Xionghuang Wan to ensure patency. Such diseases present critical and dangerous conditions. Without simultaneous administration of phlegm-expelling, detoxifying, decoctions, and pills, along with proper application of knives, needles, and stone needles, how can there be efficacy? Physicians treating these conditions must practice and master these techniques thoroughly in daily study; only then can they handle clinical cases effectively. Do not be negligent or slow, lest you harm people. Shaoshang (LU-11) Acupoint is located on the medial side of the thumb, approximately the width of a leek leaf from the nail bed. When needling, use...
