咽喉是脾胃功能状态的外在反映。由于脾胃有热，热气上冲至喉咽部位，因此产生疮疡。这些疮疡有的呈现白色脓头，有的根部发红，都属于“尸咽”的范畴。“尸咽”是指腹内的“尸虫”（一种致病邪气或寄生虫概念），向上侵蚀人的喉咽导致生疮。其症状表现为，或者发痒，或者疼痛，感觉如同吞咽甘甜之物时的不适感。
喉咽是脾胃功能状态的反映，也是气机上下通行的通道。如果脾胃有热，热气上冲，就会导致喉咽红肿疼痛。凡是发生肿痛的情况，都是因为夹杂了热邪所致。如果风毒结聚在喉间，热势炽盛则会导致肿胀堵塞不通，连水浆都无法进入，这种情况足以危及生命。
六腑功能不和，气血不调和，风邪客居在喉间，受到寒气的遏制，气机壅滞而不能消散，因此凝结而成痈肿。凡是大的一寸为疖，二寸到五寸为痈。
脏腑冷热不调，气机上下运行哽涩，结聚搏动于喉间，导致吞咽不利，或者堵塞，或者疼痛，所以称为喉咽不利。
思虑烦多会损伤心脏，心气虚弱故外邪乘虚而入。邪气积聚而不散去，就会时常影响饮食，心中感觉胀满，隐隐作痛，这被称为心痹。诊察其脉象，沉而弦的，是心痹的征候。
寒气侵入五脏六腑，因正气虚弱而发作，上冲至胸间，则形成胸痹。胸痹的症状表现是，胸中感觉胀满，噎塞不通利，皮肤下有如虫爬般的瘙痒感，喉咙里干燥涩滞，唾液粘稠。严重的，心中坚硬痞闷且急痛，肌肉苦于痹阻，绞痛如针刺，不能俯仰，胸前皮肤全部疼痛，手不能触碰，胸部胀满短气，咳嗽吐痰牵引疼痛，烦躁癖积，出冷汗，或者疼痛放射至背部脊柱。其脉象浮而微弱的就是这种病。如果不治疗，几天内即可致死。关于汤药、熨法、针灸等治疗方法，另有专门的方剂，补养宣导的方法，现在附在后面。《养生方》说：用右脚踩在左脚上面。可以消除胸痹、食后热呕。
代指，是指手指先出现肿胀，伴有灼热疼痛，肤色不暗，然后才沿着指甲边缘化脓，极端的指甲会脱落。也叫做代甲，也叫做糟指，也叫做土KT（注：原文此处可能有缺字或异体字，通常指“土疳”或类似病症）。一作“灶”。指甲是筋之余。由于筋骨热盛，气机涩滞不通，所以肿胀结聚化脓，导致指甲脱落。
The throat and pharynx are external indicators of the Spleen and Stomach. Due to heat in the Spleen and Stomach, hot qi rushes upward to the throat and pharynx, thereby generating sores (Chuang). These sores may have white heads or red roots; all belong to the category of "Shi Yan" (Corpse Throat). "Shi Yan" refers to "Shi insects" (pathogenic parasites or evil qi) within the abdomen that move upward to erode the human throat and pharynx, causing sores. The condition presents as either itching or pain, feeling similar to the discomfort when swallowing sweet substances.
The throat and pharynx are indicators of the Spleen and Stomach and serve as the pathways for the ascent and descent of Qi. If there is heat in the Spleen and Stomach, hot Qi rushes upward, resulting in swelling and pain of the throat and pharynx. Any occurrence of swelling and pain is caused by the presence of Heat pathogen. If Wind-Toxin accumulates in the throat, excessive heat causes severe swelling and blockage, preventing the intake of water and food, which can be fatal.
When the Six Fu Organs are disordered and Qi and Blood are unharmonious, Wind Pathogen lodges in the throat and is constrained by Cold. The Qi becomes stagnant and fails to dissipate, thus condensing into an abscess (Yong). Generally, a swelling one cun in diameter is called a boil (Jie), while those two to five cun in diameter are called abscesses (Yong).
If the internal organs' cold and heat are unbalanced, and the ascending and descending of Qi is obstructed, stagnation and pulsation occur in the throat, leading to difficulty in swallowing. It may feel blocked or painful, hence termed "throat and pharynx dysfunction."
Excessive worry and overthinking damage the Heart. When Heart Qi is deficient, pathogens take advantage. If pathogens accumulate and do not dissipate, they frequently impair appetite, causing a sensation of fullness in the chest and dull pain. This is referred to as Heart Bi (Heart Obstruction Syndrome). Upon pulse diagnosis, if the pulse is deep and wiry, it indicates Heart Bi.
Cold Pathogen invades the Five Zang and Six Fu Organs and manifests due to deficiency, rushing upward to the chest, resulting in Chest Bi (Chest Obstruction Syndrome). The manifestations of Chest Bi include a sensation of fullness in the chest, dysphagia and obstruction, a creeping itch-like sensation, dryness and astringency in the throat, and viscous saliva. In severe cases, there is hardness, stuffiness, and urgent pain in the heart region; muscles suffer from obstruction with cramping pain like needle pricks, making flexion and extension impossible; the skin on the anterior chest is tender to touch; chest fullness and shortness of breath occur; coughing and expectoration draw out pain; irritability and fixed masses appear; cold sweat is produced; or pain radiates to the back and spine. A floating and faint pulse confirms this diagnosis. If untreated, death may occur within several days. Decoctions, moxibustion/heat therapy, acupuncture, and stone therapy have separate specific formulas. Nourishing and guiding exercises are appended below. The *Yangsheng Fang* states: Place the right foot upon the left foot. This eliminates Chest Bi and vomiting after eating hot food.
Dai Zhi (Subungual Paronychia) begins with swelling of the finger, accompanied by burning pain, without dark discoloration initially. Subsequently, pus forms along the nail edge; in extreme cases, the nail falls off. It is also known as Dai Jia, Cao Zhi, or Tu KT (likely referring to a specific type of fungal or bacterial infection). Also written as "Zao." The nails are considered the surplus of the Sinews. Due to excessive heat in the sinews and bones and stagnant Qi flow, swelling and condensation occur, leading to suppuration and nail detachment.
