夫咽喉者，左为咽，右为喉。咽属胃，喉属肺，
乃一身之总要，百节之关防，呼吸出入之所也。经云∶
一阴一阳结而为喉痹。痹者闭也。有风、有寒、有火、
有湿、有毒、有虚，或风火相传，或寒湿相聚，其症
不一，变幻不测。故漫肿而痰多者风也，淡白而牙紧
者风寒也，紫色不肿而烂者伏寒也，红肿而脉浮者风
火也，脉沉实烂而不肿者毒也，脉细数而浮者虚火也，
细迟者虚寒也。风火寒湿毒虚，皆类而推之可也。大
凡初起之症，胗右寸洪紧者，肺风也；两关浮数者、
胃火肝风也；左寸浮洪者，心火也；右寸沉迟者，□
伏寒也；沉数者，伏热也，右尺洪大者，三焦火旺也；

医学的流派最为繁杂，其道理极为深奥难懂，而在咽喉这一专科领域，更是难中之难。咽的功能是容纳食物，喉的功能是容纳气息。容纳食物的通道连接胃脘，向下通达于脾，其性质从土而化；容纳气息的通道连接肺脘，向下通达于心，其性质从金而化。金的性质燥烈，其病理变化表现为涩滞，涩滞则导致闭塞且失去知觉，所以喉部的疾病称为痹证（痹阻不通）。土的性质湿润，其病理变化表现为泥泞，泥泞则导致壅塞肿胀且不通畅，所以咽部的疾病称为肿证（肿胀不通）。治疗咽喉疾病的人，大多知道这些道理，但至于辨别证候的虚实寒热，以及治疗方法中攻补升降的运用，要做到在毫厘之间精确剖析，在疑似之间做出正确决断，如果不能通过听声音、切脉搏、辨气色、察形态来诊断，很少不会因极细微的差错，而导致截然不同的结果。即使有人小心翼翼、试探揣摩，恐怕也难以得当。如果病情紧急却用缓慢的方法救治，伤势严重却用轻微的方法扶持，这种因循守旧的危害，与谬误背离又相差多少呢？所以说这是难中之难。我们郡中的留仙张先生向来精通医理，他对咽喉一科的研究更加深入且持久，采集收集成方的经验，参酌自己的见解，条理详细，汇编成册。从神气脉理，到面色青红紫白，声音高下沉浮，一一都有注释，清晰明了如指掌，比列眉（形容浅显易懂）更为透彻，结合所治疗的病症，如同灯下取影，百无一失。这真是救济世人的慈航，拯救危难的宝筏。他所经过验证取得疗效的案例，简直不胜枚举。同僚们都怂恿他刻印出版，使远近学习此道的人能够流传其学说，发挥其内涵，其对世间的功绩，哪里可以估量呢？因此作此序。

夫咽喉部位，左边为咽，右边为喉。咽归属于胃，喉归属于肺，这是一身的关键枢纽，百节的关隘防守，也是呼吸出入的通道。经典记载：一阴一阳之气结聚而导致喉痹。痹就是闭阻的意思。病因有风、有寒、有火、有湿、有毒、有虚，或者风火相互传变，或者寒湿相互聚集，其症状不一，变幻莫测。所以，漫肿且痰多的是风邪所致，淡白且牙关紧闭的是风寒所致，紫色不肿且溃烂的是伏寒所致，红肿且脉象浮的是风火所致，脉象沉实且溃烂但不肿的是毒邪所致，脉象细数且浮的是虚火所致，脉象细迟的是虚寒所致。风、火、寒、湿、毒、虚，都可以类推其理。大凡初起的病症，诊察右寸脉洪紧的，是肺风；两关脉浮数的，是胃火肝风；左寸脉浮洪的，是心火；右寸脉沉迟的，是伏寒；沉数的，是伏热；右尺脉洪大的，是三焦火旺；左尺脉洪而有力的，是肾虚火。这几部脉象，只是大概情况。可以总体使用六味汤加减来治疗。如果是凶险等重症，必须诊察其脉象，观察其形体，再详细探究受病的根源，仔细追问发病的起因，那么用药对症自然痊愈迅速。所以凡是治疗咽喉病症，关键在于脉象和形症名称罢了。经典记载：神圣工巧四种诊法，不过是望、闻、问、切，以此推究详查，才没有差错。我研习医术几十年来，亲眼见到其疗效，现在谨集要方九首，制药方法、看治法临症处理等，都记录在此以告知世人。
The categories of medicine are the most numerous, and its principles are extremely difficult to grasp. Among them, the specialty of the throat is particularly difficult. The pharynx (throat for swallowing) receives food, and the larynx (throat for breathing) receives air. The pathway receiving food connects to the stomach cavity, extends downward to the spleen, and transforms according to the nature of Earth. The pathway receiving air connects to the lung cavity, extends downward to the heart, and transforms according to the nature of Metal. The nature of Metal is dry; its pathological change manifests as astringency (stagnation). Astringency leads to obstruction and insensibility; therefore, diseases of the larynx are termed Bi syndrome (obstruction and pain). The nature of Earth is damp; its pathological change manifests like mud. Mud leads to congestion, swelling, and blockage; therefore, diseases of the pharynx are termed Zhong syndrome (swelling). Those who treat throat diseases generally know this, but when it comes to distinguishing the deficiency or excess, cold or heat of the syndromes, and the application of attacking or tonifying, ascending or descending in treatment methods, to analyze with precision down to the finest detail and make correct judgments amidst ambiguity, one must listen to the voice, feel the pulse, distinguish the qi, and observe the form. Without these, even a tiny difference will lead to a vast divergence in outcome. Even if one proceeds cautiously, tentatively exploring and speculating, it is likely to be inappropriate. If urgent conditions are treated with slow remedies, or severe injuries are supported with mild interventions, the harm of procrastination and following routine differs little from error. Thus, it is said to be the most difficult of difficulties. Mr. Liuxian Zhang of our county has long been proficient in medical principles. His study of the throat specialty has become increasingly profound and enduring. He collected existing prescriptions, incorporated his own insights, detailed the regulations, and compiled them into a volume. From the spirit, qi, and pulse theory, to the colors of the complexion (blue, red, purple, white), and the pitch and depth of the voice, each item is annotated clearly and intuitively, more straightforward than listing eyebrows. Combined with the treated cases, it is as accurate as taking a shadow under a lamp, with hardly any failure. It is truly a boat of compassion saving people in distress, and a raft of treasures rescuing the critical. His successful clinical experiences are too numerous to record. Colleagues urged him to have it printed, so that practitioners near and far could circulate the teachings and unfold their depths. The merit to the world is immeasurable. This is the preface.

Regarding the throat region, the left side is the pharynx, and the right side is the larynx. The pharynx belongs to the Stomach, and the larynx belongs to the Lung. They are the vital hub of the body and the defensive pass of all joints, serving as the passage for respiration. The classics state: "When Yin and Yang bind together, it results in Hou Bi (sore throat/obstruction)." Bi means closure. Etiologies include Wind, Cold, Fire, Dampness, Toxin, and Deficiency. Wind and Fire may transmit to each other, or Cold and Dampness may gather together. Symptoms vary and are unpredictable. Therefore, diffuse swelling with much phlegm indicates Wind; pale color with tight jaw indicates Wind-Cold; purple color without swelling but with ulceration indicates latent Cold; red swelling with floating pulse indicates Wind-Fire; deep and solid pulse with ulceration but no swelling indicates Toxin; fine and rapid floating pulse indicates Deficient Fire; fine and slow pulse indicates Deficient Cold. Wind, Fire, Cold, Dampness, Toxin, and Deficiency can all be deduced by analogy. Generally, in early-stage symptoms, a flooding and tight pulse at the Right Cun position indicates Lung Wind; floating and rapid pulses at both Guan positions indicate Stomach Fire and Liver Wind; a floating and flooding pulse at the Left Cun position indicates Heart Fire; a deep and slow pulse at the Right Cun position indicates latent Cold; a deep and rapid pulse indicates latent Heat; a flooding and large pulse at the Right Chi position indicates flourishing Fire in the Sanjiao (Triple Burner); a flooding and forceful pulse at the Left Chi position indicates Kidney Deficiency Fire. These pulse patterns are general guidelines. One may generally use Liuwei Tang (Six-Ingredient Decoction) with modifications for treatment. For dangerous or critical conditions, one must examine the pulse, observe the form, investigate the source of the disease in detail, and carefully inquire about the onset. Then, prescribing medication against the specific condition will naturally lead to rapid recovery. Therefore, the key to treating throat diseases lies in the pulse and the naming of symptoms. The classics state: "Divine, Sacred, Work, and Skill" refer only to Observation, Auscultation/Olfaction, Inquiry, and Palpation. By deducing and investigating through these four methods, errors can be avoided. I have practiced medicine for decades and witnessed its efficacy. Now, I have carefully collected nine essential prescriptions, methods of preparing medicines, and clinical examination and treatment techniques, recording them here for the benefit of others.
