If the disease condition does not resolve after sweating, and chills appear instead, it is due to deficiency; Shaoyao Gancao Fuzi Tang (Peony, Licorice, and Aconite Decoction) should be used as the primary treatment.
[Commentary] The character "bu" (not) in "fa han bing bu jie" (sweating, disease does not resolve) is a superfluous character. If the disease does not resolve after sweating, chills should naturally occur; how can it be described as "instead" having chills? Only when the disease has resolved but chills persist can it be termed deficiency.
This character "bu" (not) should be deleted.

The patient presents with fever, headache, and a pulse that is unexpectedly deep. If the condition does not improve, and there is body pain accompanied by (diarrhea with undigested food), the interior should be warmed, and Sini Tang (Four Reversal Decoction) is appropriate.
[Commentary] Under "body pain," the four characters "xiali qinggu" (diarrhea with undigested food) should be present. Without these four characters, the statement "the interior should be warmed" would lack basis, as there is no rationale for warming the interior when only exterior symptoms exist. Reading the Taiyin Chapter later states: "In cold damage, if the physician mistakenly uses purgatives, and subsequently diarrhea with undigested food persists without stopping, and there is body pain, the interior must be urgently rescued with Sini Tang." This clarifies the meaning further; following the classic text, this should be supplemented.

In cold damage, (if after) sweating, or vomiting, or purging, seven to eight days pass without resolution, heat becomes fixed within, both the exterior and interior are hot, there is occasional sweating with aversion to wind, severe thirst, dryness and irritation on the tongue, and a desire to drink several liters of water, Baihu Jia Renshen Tang (White Tiger Plus Ginseng Decoction) should be used as the primary treatment.
[Commentary] Under "cold damage," the two characters "ruo han" (if sweating) should be present, as sweating damages body fluids more than vomiting or purging. "Shishi ewfeng" (occasional aversion to wind) should be "shi han ewfeng" (sweating with aversion to wind). If it is not the character "han" (sweat), then "occasional aversion to wind" indicates unresolved exterior syndrome, against which Baihu Tang (White Tiger Decoction) is contraindicated. The Treatise states: For fever without sweat and unresolved exterior syndrome, Baihu Tang must not be given. For thirst with desire to drink water and no exterior syndrome, Baihu Jia Renshen Tang (White Tiger Plus Ginseng Decoction) is used. Careful study of the original text will reveal this; supplementation and correction are required.

After sweating, if the pulse is floating and rapid, (urination is difficult), and there is irritability and thirst, Wuling San (Five-Ingredient Powder with Poria) should be used as the primary treatment.
[Commentary] Under "pulse floating and rapid," the four characters "xiaobian buli" (urination is difficult) should be present. Without these four characters, the irritability and thirst would be due to internal heat in the Yangming channel causing dry mouth, which is an indication for Baihu Tang (White Tiger Decoction). It is precisely because of urination difficulty leading to irritability and thirst that it constitutes the irritability and thirst of water-heat entanglement in the Taiyang channel, fitting the indication for Wuling San (Five-Ingredient Powder with Poria). Using Wuling San (Five-Ingredient Powder with Poria) without urination difficulty would violate the prohibition against exhausting body fluids again. Moreover, in the upper section of the Taiyang chapter, there are several similar cases; only the case of "vomiting immediately after drinking water" lacks the phrase "urination is difficult" because the water fails to descend; all others contain these four characters. These four characters here were likely lost during transcription and should be supplemented.

After taking Guizhi Tang (Cinnamon Twig Decoction), or after purgation, if there is still stiffness and pain in the head and neck, mild fever resembling a feather covering, absence of sweat, fullness and slight pain in the epigastrium, and urination difficulty, Guizhi Tang (Cinnamon Twig Decoction) with {Gui} [Shaoyao] removed plus Fuling (Poria) and Baizhu (Atractylodes Macrocephala Rhizome) should be used as the primary treatment.
[Commentary] Removing Guizhi (Cinnamon Twig) should actually mean removing Shaoyao (White Peony Root). If this formula removes Guizhi (Cinnamon Twig), what treats the unresolved exterior symptoms of head/neck stiffness, fever, and absence of sweat? Carefully examining the instruction to take this decoction, it says "rest according to Guizhi Tang (Cinnamon Twig Decoction) preparation methods," revealing the logic. After taking Guizhi Tang (Cinnamon Twig Decoction), one covers warmly for about an hour until the whole body has a slight sweat; this is the method for taking Guizhi Tang (Cinnamon Twig Decoction). If Guizhi (Cinnamon Twig) is removed, the remaining ingredients are Baishao (White Peony Root), Gancao (Licorice), Fuling (Poria), and Baizhu (Atractylodes Macrocephala Rhizome), lacking acrid-sweet herbs to move Ying and Wei. Saying "rest according to Guizhi Tang (Cinnamon Twig Decoction) methods" would be meaningless. Furthermore, in the Treatise, for pulse surging with chest fullness, sweating, and aversion to cold, Guizhi Qu Shaoyao Jia Fuzi Tang (Cinnamon Twig Decoction with Shaoyao Removed plus Aconite) is used; Shaoyao (White Peony Root) is removed because of chest fullness. Although the current syndrome differs slightly, the presence of "fullness" is the same, indicating that Shaoyao (White Peony Root) should be removed. This should be corrected.

In cold damage, if the physician uses pill-based strong purgatives, and body heat persists with slight irritability, Zhizi {Ganjiang} [Chidou] Tang (Gardenia {Dried Ginger} [Fermented Soybean] Decoction) should be used as the primary treatment.
In cold damage lasting five to six days, after strong purgation, if body heat persists and there is knotted pain in the heart region, the disease has not yet resolved. Zhizi {Chidou} [Ganjiang] Tang (Gardenia [Fermented Soybean] {Dried Ginger} Decoction) should be used as the primary treatment.
[Commentary] Zhizi Ganjiang Tang (Gardenia and Dried Ginger Decoction) should be Zhizi Chidou Tang (Gardenia and Fermented Soybean Decoction); Zhizi Chidou Tang (Gardenia and Fermented Soybean Decoction) should be Zhizi Ganjiang Tang (Gardenia and Dried Ginger Decoction). There is no rationale for using Ganjiang (Dried Ginger) for irritability and heat, nor for using Chidou (Fermented Soybean) for knotted pain. They should be swapped.

Taiyang syndrome, with a floating-tight pulse, absence of sweat, fever, and body pain, unresolved after eight or nine days, with exterior symptoms still present, requires sweating therapy, (Ma Huang Tang (Ephedra Decoction) is the primary treatment). After taking the medicine, symptoms slightly subside, the person becomes irritable and closes their eyes; in severe cases, epistaxis (nosebleed) will occur, and the disease resolves through epistaxis. The reason for this is excessive Yang qi stagnation.
[Commentary] Zhang Jianshan said: The five characters "Ma Huang Tang (Ephedra Decoction) is the primary treatment" should not be placed under "excessive Yang qi stagnation." How could Ma Huang Tang (Ephedra Decoction) be used after the disease resolves via epistaxis? Above "after taking the medicine," there is no mention of which medicine was taken. Moving these five characters above resolves the textual inconsistency; they should be moved.

In cold damage with constipation for six or seven days, accompanied by headache and fever, Chengqi Tang (Gut-Draining Decoction) may be given. If the urine is clear, it indicates the pathogen is not in the interior but remains in the exterior, requiring sweating therapy. If there is {Ruo} [Ku] headache, epistaxis will likely occur, and Guizhi Tang (Cinnamon Twig Decoction) is appropriate.
[Commentary] The character "ruo" (if) in "ruo tou tong" (if headache) should be "ku" (bitter/severe). Only severe headache is a sign that inevitably leads to epistaxis; if it were "ruo" (if), then any headache would cause epistaxis. This should be corrected.

Fullness and stuffiness in the epigastrium, which feels [not] soft upon pressure, with a floating pulse at the Guan position, is primarily treated with Dahuang Huanglian Xiexin Tang (Rhubarb, Coptis, and Scutellaria Heart-Draining Decoction).
[Commentary] "An zhi ru" (soft upon pressure) should be "an zhi bu ru" (not soft upon pressure). If it is soft upon pressure, it is a deficiency-type fullness, where tonification is insufficient, let alone using Dahuang (Rhubarb) for purging. This should be supplemented.
