问曰：病欬逆，脉之，何以知此为「肺痿」肺痈？当有脓血，吐之则死，其脉何类？
师曰：寸口脉「浮」〔微〕而数，「浮」〔微〕则为风，数则为热，「浮」〔微〕则
汗出，数则恶寒。风中于卫，呼气不入；热过于荣，吸而不出。风伤皮毛，热伤血脉
。风舍于肺，其人则咳，口干，喘满，咽燥不渴，时唾浊沫，时时振寒。热之所过，
血为之凝滞，畜结痈脓，吐如米粥。始萌可救，脓成则死。

Q: In a patient presenting with cough and qi reversal, how can one distinguish between "Fei Wei" (Lung Withering) and "Fei Yong" (Lung Abscess) through pulse diagnosis? If pus and blood are present, and vomiting leads to death, what kind of pulse would this be?
The Master replied: The Cun Kou (inch position) pulse is Floating (superficial) and Rapid. A Floating pulse indicates Wind pathogen; a Rapid pulse indicates Heat. A Floating pulse leads to sweating; a Rapid pulse leads to aversion to cold. Wind invades the Wei (Defensive) level, causing exhalation without deep penetration; Heat invades the Ying (Nutritive) level, causing inhalation without full entry. Wind damages the skin and hair pores; Heat damages the blood vessels. When Wind lodges in the Lung, the patient experiences cough, dry mouth, wheezing and chest fullness, dry throat without thirst, frequent spitting of turbid froth, and intermittent chills. Where Heat passes, blood coagulates and stagnates, accumulating to form an abscess with pus; the expectoration resembles congee. If treated at the initial stage, it can be saved; once pus has formed, it is fatal.
[Commentary]
Before "Fei Yong" (Lung Abscess), the characters "Fei Wei" (Lung Withering) should appear; otherwise, the discussion on Fei Wei lacks context. This is likely a lacuna in the bamboo slips and should be supplemented. The three instances of "Wei" (Micro/Weak) in the pulse description should actually be "Fu" (Floating); this correction aligns with the textual flow.
For "Fire" (Da) reversing qi upward, with difficulty in the throat, to stop the reversal and descend the qi, Mai Men Dong Tang (Ophiopogon Decoction) is indicated.
[Commentary]
The character "Da" (Big/Great) in "Da Ni Shang Qi" should be "Huo" (Fire); this correction ensures consistency between the text, pathology, and prescription.
Abdominal fullness that decreases intermittently but returns to its previous state indicates Cold; warm herbs should be administered, [specifically Hou Po Sheng Jiang Gan Cao Ban Xia Ren Shen Tang (Magnolia Bark, Fresh Ginger, Licorice, Pinellia, and Ginseng Decoction)].
[Commentary]
This chapter lacks a formula for treating deficiency-cold abdominal fullness. Below "warm herbs should be administered," the phrase "Yi Hou Po Sheng Jiang Gan Cao Ban Xia Ren Shen Tang Zhu Zhi" (Suitable for treatment with Magnolia Bark... Decoction) consisting of fourteen characters is missing due to a lacuna and should be added. Reference to the *Tai Yin* chapter of the *Shang Han Lun* confirms this.
The patient presents with sallow complexion, "dryness" (Zao) without thirst, and Cold-Excess in the "Stomach" (Xiong/Chest). If accompanied by unceasing diarrhea, it is a death case.
[Commentary]
"Zao er bu ke" (Irritable/restless without thirst) should be "Zao er bu ke" (Dry without thirst) for textual coherence. "Xiong Zhong Han Shi" (Cold-Excess in the Chest) should be "Wei Zhong Han Shi" (Cold-Excess in the Stomach); if it were Cold-Excess in the Chest, it would not logically lead to the prognosis of death via unceasing lower bowel movements. Correction is required.
[If the pulse is Rapid and Tight, it becomes Xian (Wiry), resembling a bowstring, firm upon pressure; for a Xian-Rapid pulse,] [one should purge the Cold]; for a Tight, Large, and Slow pulse, there must be hardness below the heart. [One should purge the Cold,] for a Large and Tight pulse indicates Yang containing Yin, and purgation is permissible.
[Commentary]
The nineteen characters "Qi Mai Shu Er Jin, Nai Xian, Zhuang Ru Gong Xian, An Zhi Bu Yi, Mai Shu Xian Zhe" (Its pulse is rapid and tight, becoming wiry, shaped like a bowstring, unmoving upon pressure, the rapid-wiry pulse...) are extraneous text (interpolations). Reference to the *Bian Mai Fa* chapter of the *Shang Han Lun* confirms this deletion. The four characters "Dang Xia Qi Han" (Should purge its Cold) should be moved below "Xin Xia Jian" (Hardness below the heart) for logical coherence.
□ Lower "Fullness" (Pian/Side) pain, fever, with a Tight-Wiry pulse, indicates Cold; treat with warm purgatives, suitable for Da Huang Fu Zi Tang (Rhubarb and Aconite Decoction).
[Commentary]
The character "Pian" (Side) in "Pian Tong" should be "Man" (Fullness). Correction is required.
Palpation revealing fullness and pain below the heart [accompanied by tidal fever] indicates Excess; purgation is indicated, suitable for Da Chai Hu Tang (Major Bupleurum Decoction).
[Commentary]
Below "Palpation revealing fullness and pain below the heart," the three characters "You Chao Re" (Has tidal fever) are missing. Without these, Da Chai Hu Tang would not be appropriate. Supplementation is required.
Abdominal pain with a Wiry-Tight pulse: Wiry indicates obstruction of Wei Qi movement, leading to aversion to cold; Tight indicates anorexia. The struggle between pathogenic factors and righteous qi constitutes Han Shan (Cold Spasm). Pain circling the umbilicus, with spontaneous sweating during attacks, and cold limbs, [if the pulse is Deep-Tight,] is treated with Da Wu Tou Jian (Major Aconite Decoction).
[Commentary]
The pulse description here is repetitive. The next paragraph has symptoms but no pulse. The five characters "Qi Mai Chen Jin Zhe" (If the pulse is Deep-Tight) should be moved below "Li Ji" (Tenesmus/Urge) in the next paragraph. However, a Wiry-Tight pulse signifies extreme tension, belonging to severe Cold Spasm. The character "Bai" (White) in "Bai Han" should be "Zi" (Self/Spontaneous). Correction is required. The "Deep-Tight" pulse in the next paragraph corresponds to interior pain and belongs to mild Cold Spasm; it should be moved.
Han Shan (Cold Spasm), abdominal pain, and □ pain with tenesmus, [if the pulse is Deep-Tight,] is treated with Dang Gui Sheng Jiang Yang Rou Tang (Angelica Sinensis, Fresh Ginger, and Mutton Decoction).
[Commentary]
Below "□ pain with tenesmus," the five characters "Qi Mai Chen Jin Zhe" (If the pulse is Deep-Tight) from the preceding paragraph should be added.
Han Shan (Cold Spasm), abdominal pain, cold extremities, numbness in hands and feet, and body pain which cannot be cured by moxibustion, acupuncture, or various medicines, is treated with [Di Dang] Wu Tou Gui Zhi Tang (Aconite and Cinnamon Twig Decoction).
[Commentary]
The two characters "Di Dang" are extraneous text.
Q: How can one differentiate Su Shi (Retained Food) in patients? The Master said: The Cun Kou pulse is Floating and Large; upon pressing, it feels Rough (Se); the Chi (cubit) position is also [Large] (Wei/Weak) and Rough. Thus, retained food is known, and Da Cheng Qi Tang (Major Order the Qi Decoction) is indicated.
[Commentary]
The character "Wei" (Weak) in "Chi Zhong Yi Wei Er Se" should be "Da" (Large) according to the *Shang Han Lun*. Correction is required.
