Wang Kentang: If the Taiyang disease (disease of the Taiyang channel) has persisted for three days, and although sweating therapy (diaphoresis), emesis, purgation, or warm needle therapy have been applied, the condition remains unresolved, this is termed a "ruined disease" (bad illness resulting from mismanagement). At this stage, Guizhi Tang (Cinnamon Twig Decoction) cannot be fixedly prescribed. One must observe the pulse and symptoms to determine what error (mis-treatment) was committed, and then treat according to the specific presentation. The term "ni" (adverse/rebellious) refers to situations where sweating was induced when it should not have been, or purgation was used when it should not have been, or when sweating and purgation were excessive; these actions do not accord with therapeutic principles, hence they are called "adverse." "Treating according to the syndrome" means, as stated later: "If the disease does not resolve after sweating," or "if the disease persists after sweating or purgation," one prescribes specific decoctions accordingly. The phrase "treating according to the syndrome" is flexible in meaning and broad in scope. Wang Bing, Han Zhihe, and other physicians erroneously treated "ruined disease" as a distinct syndrome and prescribed Roushang Tang (Mutton Soup) as the primary treatment.

If the original Taiyang disease does not resolve and transitions into Shaoyang disease (disease of the Shaoyang channel), presenting with hardness and fullness below the costal margin, dry retching, inability to eat, and alternating chills and fever, if no emesis or purgation has yet been performed and the pulse is deep and tight, Xiaochaihu Tang (Minor Bupleurum Decoction) should be administered. However, if due to the use of emesis, purgation, sweating, or warm needles, the patient develops delirium (speaking nonsense), indicating that the Chaihu syndrome has ceased, this constitutes a ruined disease. One must ascertain the nature of the adverse treatment and manage it according to appropriate principles.

Zhao Xianke: In Zhang Zhongjing's discussions, "ruined disease" refers to conditions such as deficiency-heat irritability, chest binding (jie xiong), epigastric fullness (pi qi), internal irritability after vomiting, and abdominal distension following the erroneous application of sweating, emesis, or purgation in Taiyang disease. This precisely refers to the inapplicability of Guizhi Tang and the cessation of Xiaochaihu Tang syndromes. It certainly does not refer to illnesses caused by "heterogeneous pathogens" (yi qi) as described in *Huoren Shu* (The Man Who Saves Lives). Zhang Zhongjing also stated, "Contracting heterogeneous pathogens leads to transformation into other diseases," which refers to the mixing of two or three pathogens causing illness. Since these conditions lack definitive names, they differ from the four types of warm diseases (wen bing) and are thus termed "transformed diseases." Regarding the four channels of warm diseases, Zhang Zhongjing posited that winter cold injury manifests as warm disease in spring; if the warm disease persists and re-exposure occurs, it transforms into warm malaria, wind-warmth, warm toxin, or warm epidemic. These were never termed "ruined," but rather "transformed syndromes." Thus, "ruined disease" and "transformed syndrome" are distinct nomenclatures. It is clear that heterogeneous pathogens do not constitute ruined diseases. Consider this carefully: if warm malaria were truly a ruined disease, Zhang Zhongjing would not have mentioned the cessation of the Xiaochaihu Tang syndrome. Ponder upon this.

Shizhai Formula: When the yin and yang patterns of Shanghan (Cold Damage) are indistinguishable, or medicinal errors cause the patient to become critically ill and near death, this formula may be administered even seven days after onset. Legend holds that its efficacy is nearly infallible. Preparation: Take high-quality Ren Shen (Ginseng Radix et Rhizoma), 1 liang, remove the rhizome (lu), slice thinly. Boil in 1 sheng (approx. 1000 ml) of water in a silver or ceramic vessel until reduced to 1 zhan (approx. 200 ml). Cool the decoction using fresh water until cold. Administer in a single dose. The expected reaction is perspiration emerging only from the tip of the nasal bridge, dripping like water droplets, which indicates the drug's effect. This is miraculous. Su Taoguang reported: The Abbot of the Vice Minister's residence once saved dozens of people using this formula. When Envoy Wang served in Qingliu County, the son of Che Shentu Xingfu suffered from an epidemic postpartum for over ten days, already constituting a ruined disease. Upon inquiry, he was found to be taking only Ren Shen, after which he recovered. At that time, the existence of this specific formula was unknown; it was merely a coincidental alignment.

Haizang (Zhang Yuansu): After excessive sweating and purgation in yang-pattern diseases, yang collapses externally and blood depletes internally. Upper depletion involves body fluids (jin ye), while lower depletion involves essences. With both fluids and essences exhausted, Roushang Tang (Mutton Soup) should be used to tonify. How much more so for yin-pattern diseases, which require warming and tonification? This parallels the case of Taiyang disease presenting with tremors and shaking, treated with Zhenwu Tang (True Warrior Decoction); even in such advanced yang-pathology, warming is necessary. How much more essential is tonification for internal yin-cold patterns?

Han Zhihe: Patients with blood deficiency due to postpartum hemorrhage are suitable for Roushang Tang (Mutton Soup). In Shanghan, if excessive sweating and purgation lead to collapse of yang and loss of blood, using only Jiuni Tang (Rescue the Perdition Decoction) will yield slow results. Roushang Tang acts swiftly. Although the patient's complexion may appear to show yang heat, this is likely "guest heat" (false heat). Yin qi in the upper, middle, and lower jiao (burners) is abundant. If the lower jiao is regulated to generate yang, the yang qi of the upper jiao can descend, and the dantian (lower abdomen) will find its proper residence. Qi has levels of ascent and descent; diseases have distances of origin and manifestation; syndromes have interior-exterior distinctions; treatments have degrees of severity. Healing occurs when each aspect is appropriately addressed. Therefore, if the disease has persisted for eight or nine days, and excessive sweating/purgation has resulted in deep, thin, and weak pulses, with the patient curling up, lying down, aversion to sound, skin goosebumps, and chills resembling malaria, Roushang Tang (Mutton Soup) is indicated.

Roushang Tang (Mutton Soup) Formula: Dang Gui (Angelicae Sinensis Radix), Bai Shao Yao (Paeoniae Radix Alba), Mu Li (Ostreae Concha) [Note: Text mentions Chi Shi Zhi here contextually or as variant, but standard Mu Li is Oyster Shell], Sheng Jiang (Zingiberis Rhizoma Recens), Gui Zhi (Cinnamomi Ramulus), Long Gu (Fossilia Ossis Mastii), Hei Fu Zi (Aconiti Lateralis Radix Praeparata - Black Prepared Aconite Root). Dosages: Dang Gui, Bai Shao Yao, Mu Li (Chi Shi Zhi/Red Ochre per text note, usually Mu Li in standard texts, adhering to text: Chi Shi Zhi) 1 liang each; Sheng Jiang 2 liang; Gui Zhi 7 qian 5 fen; Long Gu (reddish throughout) 0.5 liang; Hei Fu Zi (prepared, skin and core removed) 4 qian. Grind herbs into coarse powder. For each dose, take 1 liang of herb powder, 4 liang of mutton, 5 cun of scallion white, and ginger heart. Chop finely. Boil in 5 sheng of water until reduced by half. Filter and remove dregs. Divide into three doses. Note: This formula is suitable for yin-patterns.
