寸口脉象数而实，是肺痈（肺部化脓性病变）的征象。如果脉象短而涩，表示疾病将自行痊愈。如果脉象浮大，则难以治疗。
所谓肺痈，是由于寒热之气内侵于肺，导致气机结聚而形成的。大概是因为调理不当，劳损伤及气血，风寒之邪得以乘虚而入。寒邪郁久生热，风邪亦能生热，邪气壅积不散，最终形成肺痈。症状表现为咳嗽、脑漏（鼻流浊涕）、右胁部隐隐作痛、双下肢肿胀、咽干口燥、心烦闷乱且多渴、时常吐出黄色唾沫且气味腥臭，状如糯米粥，这种情况属于难治。如果有发热并伴有呕吐者，不可强行止呕，待脓液排尽后，疾病会自愈。如果呕吐物为黄色腥臭或带粉红色的脓液，则是肺痿（肺部萎弱不用之病）。大抵而言，若脉象细而沉，说明里气虚弱且病情发生了变证。
有一种论述关于咳嗽，吐出脓血，气味腥臭令人难以忍受的，属于肺痈。
方药：黄（蜜水炒制）、防风、金银花、忍冬藤、金沸草、牛膝、桔梗（以上各等分）。
用法：取一只鸭子，勒死，剖开，将上述七味药放入鸭腹内，用优质酒煮至酒尽为止。食用鸭肉，将药渣晒干研成粉末，用酒调服。服药后，再服用净脓汤。
净脓汤：此汤在吃鸭之后应当服用。
组成：甘草四两，锉成大块，用水煎煮，一次性顿服。如果患者无法吞咽，可将其吐出。
化痰止咳丸：
组成：白矾（煅枯二两）、百草霜（一两）。
用法：将这两味药研成粉末，用清水泛丸。每次服用三五十丸，用人参、五味子各三钱煎汤送服。按三日疗程使用。
另一种论述关于治疗肺虚，使用白鸭一只，去除内脏，用薏苡仁、杏仁各一两，放入鸭腹中，在饭上蒸熟。去掉药物只吃鸭肉，对补肺有很大功效。
另一种论述关于肺痈，吐出的脓液腥臭，让病人嚼一粒黄豆，如果感觉不到豆子的味道，即为肺痈。
另一种论述关于肺痈，将薏苡仁略炒后研成粉末，用糯米饮调服。也可以加入粥中煮熟食用，或者用水煎服。服用后可排出脓血而安宁。
保肺丹（方剂见瘿瘤章节）
凡是治疗肺痈，必须间歇性地服用此药，以保护膈膜，防止溃破透入心肺，最为恰当。即使用矾蜡丸，用蜜水送下。
The pulse at the Cun Kou (radial artery) is rapid and full, indicating Fei Yong (Lung Abscess). If the pulse is short and choppy, the disease will heal spontaneously. If the pulse is floating and large, it is difficult to treat.
Fei Yong (Lung Abscess) arises from cold and heat pathogens invading the interior of the Lung, causing Qi stagnation and accumulation. This is generally due to improper regulation, labor injury damaging Qi and Blood, allowing Wind-Cold pathogens to take advantage of the deficiency. Cold transforms into Heat, and Wind also generates Heat; pathogenic factors accumulate and do not disperse, eventually forming a Lung Abscess. Symptoms include coughing, nasal discharge (brain leakage), dull pain in the right hypochondrium, swelling and fullness in both legs, dry throat and mouth, mental restlessness with excessive thirst, and frequent expectoration of yellow saliva with a foul, fishy odor, resembling glutinous rice porridge. This condition is difficult to treat. If there is fever accompanied by vomiting, one should not forcibly stop the vomiting; once the pus is exhausted, the patient will heal spontaneously. If the vomitus consists of yellow, foul-smelling pus or pus mixed with pinkish blood, it indicates Fei Wei (Lung Flaccidity). Generally, if the pulse is fine and deep, it indicates interior deficiency and transformation of symptoms.
One discussion concerns coughing up pus and blood with an unbearable foul odor, which belongs to Fei Yong (Lung Abscess).
Formula: Huangqi (Astragali Radix, stir-fried with honey), Fangfeng (Saposhnikoviae Radix), Jinyinhua (Lonicerae Japonicae Flos), Rendongteng (Lonicerae Japonicae Caulis), Jinfeicao (Bellis Perennis Herba), Niuxi (Achyranthis Bidentatae Radix), Jiegeng (Platycodonis Radix) (all in equal parts).
Preparation: Take one duck, strangle it, cut it open, and place the aforementioned seven herbs inside the duck's cavity. Boil with high-quality wine until the wine is completely consumed. Eat the duck. Dry the herbal dregs, grind them into powder, and administer with wine. After taking this, consume Jing Nong Tang (Pure Pus-Removing Decoction).
Jing Nong Tang (Pure Pus-Removing Decoction): This decoction should be taken after eating the duck.
Composition: Gancao (Glycyrrhizae Radix et Rhizoma) four liang, cut into large pieces, decocted in water, and taken in one dose. If the patient cannot swallow, induce vomiting.
Hua Tan Zhi Ke Wan (Phlegm-Resolving and Cough-Stopping Pill):
Composition: Baifan (Alumen, calcined until dry) two liang, Baicaoshuang (Fuliginis Pulvis) one liang.
Preparation: Grind these two ingredients into powder, form pills using clear water. Take 30–50 pills per dose, delivered with a decoction of Renshen (Ginseng Radix) and Wuweizi (Schisandrae Chinensis Fructus), each three qian. Use over a three-day period.
Another discussion on treating Lung Deficiency: Use one white duck, remove the internal organs, place Yiren (Coicis Semen) and Xingren (Armeniacae Semen Amarum), each one liang, into the duck's abdomen. Steam thoroughly over rice. Remove the herbs and eat only the duck meat. This greatly tonifies the Lung.
Another discussion on Lung Abscess: Have the patient chew one soybean. If the patient does not perceive the taste of the bean, it indicates Lung Abscess.
Another discussion on Lung Abscess: Slightly stir-fry Yiyiren (Coicis Semen), grind into powder, and take with Mijiu Yin (Glutinous Rice Beverage). It can also be cooked in congee or decocted in water. Administration leads to the discharge of pus and blood, bringing relief.
Baofei Dan (Lung-Protecting Pill) (See formula for Ying Liu / Goiter).
In all cases of treating Lung Abscess, this medicine must be administered intermittently to protect the diaphragmatic membrane, preventing perforation into the Heart and Lung. This is most appropriate. Specifically, Fanla Wan (Alum-Wax Pill) should be taken with honey-water.
