许先生论梁宽父病右胁肺部也，咳而唾血，举动喘逆者，肺胗也，发热，脉数，不能食者，火来刑金，
肺与脾俱虚也。肺脾俱虚而火乘之，其病为逆。如此者，例不可补泻，若补金则虑金与火持而喘咳益增
，泻火则虑火不退位而 癖反盛，正宜补中益气汤先扶元气，少以治病药加之。闻已用药而未获效，必病
势苦逆而药力未到也，远期秋凉庶可复耳！盖肺病恶春夏火气，至秋冬火退，只宜于益气汤中，随四时升降寒
热及见有症增损服之。或觉气壅，间与加减枳术丸；或有饮，间服《局方》枳术汤。数日逆气少回，逆气回
则治法可施，但恐今日已至色青、色赤及脉弦、脉洪，则无及矣！病后不见色、脉，不能悬料。以既愈复发
言之，惟宜根据准四时用药，以扶元气，庶他日既愈不复发也。其病初感必深，且所伤物恐当时消导尚未尽
停滞，淹延变生他症，以至于今，宜少加消导药于益气汤中，庶可渐取效也。
丹溪曰∶杂合邪者，当以杂合法治之。譬如恶寒发热，得之感冒，明是外邪，脉得浮数而气口又
紧盛，明是食伤。病者又倦怠，重按其脉俱有豁意，而胸膈痞满牵引两胁。轻者其脉又似乎弦，此又平时多
怒肝邪所为也；细取左尺又似沉弱，此又平时房劳之过也。治法宜以感冒一节放下，视其形色强弱浓薄，且与
补中化食行滞，后凉胃火，而以姜辣行之，中气稍回，伤气稍行，津液得和，通体得汗，外邪自解。若不审
求，只管表散。 又不推究兼见之邪脉，又不穷问所得之病。因与性情，执着及巧施杂合治法，将见正气
自虚，邪气自固，皆拙工之过也。
许先生论述梁宽父的病症，病位在右胁部的肺部。患者咳嗽并咳出血液，活动后气喘逆乱，这是肺痈（肺部化脓性病变）。伴有发热、脉象数急、不能进食，这是火邪克制肺金，导致肺与脾都虚弱。肺和脾都虚弱而火邪乘虚侵袭，病情就会恶化。对于这种情况，常规方法不可单纯使用补法或泻法。如果补益肺气，则担心肺金与火邪相持不下，导致气喘咳嗽更加严重；如果清泻火邪，又担心火邪不退位，反而使积聚之症加重。此时正应当先用补中益气汤扶助元气，再少量加入治疗具体疾病的药物。听说已经用药但未获疗效，一定是因为病势凶险顽固，而药力尚未到达病所，等到秋季凉爽之时，或许可以痊愈。因为肺病厌恶春夏季节的火气，到了秋冬季节火气退去，只应当在益气汤的基础上，根据四季气候的升降寒热变化以及出现的症状进行增减服用。如果觉得气机壅滞，偶尔给予加减枳术丸；如果有痰饮，偶尔服用《局方》中的枳术汤。几天后逆乱之气稍微回缓，逆气回缓则治疗方法可以施行，但恐怕如今已经出现面色青、面色赤以及脉象弦、脉洪大等情况，那就来不及救治了！疾病之后没有观察到面色和脉象，无法凭空推测。从病愈后复发来说，只应当依据四时规律用药，以扶助元气，这样将来病愈后才不会复发。这个病初感时必定病位较深，而且所伤之物恐怕当时消导化积并不彻底，仍有停滞，拖延时间变生其他病症，以至于现在，应当在益气汤中少量加入消导药物，才可能逐渐取得疗效。
丹溪先生说：对于多种邪气混杂的病症，应当采用综合兼治的方法。例如恶寒发热，这是由于感冒所致，明显是外邪，脉象浮数且气口脉紧盛，明显是饮食损伤。病人又感到倦怠，重按脉搏都有空虚之意，且胸膈痞满牵引两胁。轻症者脉象似乎弦，这又是平时多怒导致肝气郁结所为；仔细诊察左尺脉又似乎沉弱，这又是平时房劳过度的缘故。治疗方法应当先把感冒这一节放下，观察病人的形色强弱胖瘦，先给予补中、化食、行滞的药物，然后清降胃火，并用姜辣类药物通行阳气，中气稍微恢复，受伤的气血稍微运行，津液调和，全身出汗，外邪自然解除。如果不审察求因，只管发表散邪。又不推究兼见的邪气和脉象，又不详尽询问所得的疾病。因为迎合病人的性情，执着于技巧性地施用杂合治法，将会看到正气自虚，邪气自固，这都是庸医的过错。
Mr. Xu discussed the case of Liang Kuanfu, whose illness was located in the lung area of the right hypochondrium. He suffered from coughing and expectorating blood, and panting with reverse flow upon movement; this is Lung Abscess (Fei Zhong, a purulent lesion of the lung). Accompanied by fever, rapid pulse (Shu Mai), and inability to eat, this indicates Fire Evil (Huo Xie) overcoming Metal (Lung), resulting in deficiency of both the Lung and Spleen. When both the Lung and Spleen are deficient and Fire Evil takes advantage of this, the condition becomes adverse. In such cases, standard tonification or purgation methods should not be used. If one tonifies Metal (Lung), there is a concern that Metal and Fire will contend, exacerbating panting and coughing; if one purges Fire, there is a concern that Fire will not retreat from its position, causing stagnation masses (Pi Ji) to worsen. It is appropriate to first use Buzhong Yiqi Tang (Tonify the Middle and Boost Qi Decoction) to support Yuan Qi (Primary Qi), adding a small amount of medication for the specific disease. It was heard that medication had been administered without effect; this must be because the disease momentum is severe and resistant, and the medicinal force has not yet reached the site. Perhaps recovery can be expected when autumn coolness arrives! Since Lung diseases dislike the Fire energy of Spring and Summer, and when Autumn and Winter arrive the Fire energy recedes, one should only adjust the dosage of Yiqi Tang according to the rising and falling, cold and heat of the four seasons, and modify it based on visible symptoms. If one feels Qi stagnation, occasionally administer Jiajian Zhizhu Wan (Modified Atractylodes and Immature Bitter Orange Pill); if there is fluid retention, occasionally administer Zhizhu Tang (Atractylodes and Immature Bitter Orange Decoction) from *Jufang*. After a few days, if the reverse Qi slightly returns, treatment methods can be applied. However, if the complexion has already turned green or red, and the pulse has become wiry (Xian Mai) or flooding (Hong Mai), it may be too late! Without observing the complexion and pulse after the illness, one cannot speculate remotely. Speaking of recurrence after recovery, one should strictly follow seasonal medication principles to support Yuan Qi, so that future recoveries do not recur. The initial infection must have been deep, and the damaged substances might not have been fully guided out at that time, remaining stagnant. Prolonged delay led to other symptoms, resulting in the current state. It is advisable to add a small amount of digestive/guiding-out medications to Yiqi Tang, so that gradual efficacy can be achieved.
Danxi stated: For mixed evil conditions (Zahe Xie), one should employ mixed treatment methods. For example, aversion to cold and fever, caused by common cold, clearly indicate external evil; the pulse is floating and rapid, and the Qi Kou pulse is tight and full, clearly indicating food injury. The patient also feels fatigued; heavy pressure on the pulse reveals a hollow sensation, accompanied by chest and diaphragm stuffiness pulling into both hypochondria. In mild cases, the pulse seems wiry, which is due to Liver evil caused by frequent anger; careful examination of the Left Chi pulse seems deep and weak, which is due to past excessive sexual activity. The treatment method should set aside the common cold aspect, observe the patient's form, color, strength, and thickness, and initially provide medications to tonify the middle, transform food, and move stagnation. Then, cool Stomach Fire, and use ginger and pepper to promote circulation. Once Middle Qi slightly recovers, injured Qi moves, fluids harmonize, and the whole body sweats, external evil resolves naturally. If one does not investigate thoroughly but merely disperses the exterior, fails to deduce concurrent evils and pulses, and fails to inquire exhaustively about the origin of the disease, while catering to the patient's temperament and stubbornly applying clever mixed treatments, one will see Primary Qi becoming deficient and Evil Qi becoming entrenched. This is all the fault of clumsy practitioners.
