火邪侵入肺脏，导致烦闷。火邪侵入肾脏，导致躁动。如果烦躁症状同时出现在上部，是因为肾（子）与肺（母）相通。头发湿润如油，喘息不止，这是总体描述肺气衰竭。鼻子是肺的外在征候，肺气通于鼻，鼻中呼吸气粗大，说明病在肺。头发是血液的余绪，由肾气所主。头发湿润如油，是火邪逼迫肾水至最高部位，这是肾水即将枯竭的表现。张仲景认为头发湿润、喘息急促是肺气衰竭，同时也兼及肾脏而言。头发位于头顶最高处，虽然属于肾，但肺是五脏中最高的脏器，所以说肺气衰竭兼及肾脏。大抵肺肾相通，肺既然已经衰竭，那么肾也无需多说就知道已经衰竭了。有人问：烦闷是心导致的，躁动也是心导致的，为什么烦归于肺、躁归于肾呢？心是君火，与邪热相接，上下贯通，火热使金（肺）干燥，使水（肾）亏损，唯独剩下火邪存在。所以肺、肾与心结合而表现为烦躁。这种烦虽然表现在肺，躁虽然表现在肾，其实是由心火引起的。如果有宿食积滞而导致烦躁的，用栀子大黄汤主治。
回答说：足阳明经就是胃，难道有这样的说法吗？伤寒病开始从皮毛侵入，是从肺开始的。肺主管声音，邪气入于心则表现为言语异常。胃即戊土，戊属火化，下行联系肾和肝。
伤寒表证，发热、恶寒且口渴，与里实证相似。但伴有头痛、身热、目痛、鼻干、不能安卧，用白虎汤主治，这是阳明经病。正阳阳明的气分病，脉象洪大，起初没有有形之邪。杂病的里证，发热、怕热且口渴，只有眼睛发红的是病在脏。手太阴肺不足，不能统摄阳气。适宜用枸杞、生地黄、熟地黄等药物治疗，脉象洪大严重时会出现呕血，这是先有形的病变。
气分病在体表，误用治血的药，不会造成伤害，因为是为了安定血液而益阴。血分病在体内，误用治气的药，用白虎汤是不对的，因为会泻肺而损伤阴液。
When Fire pathogen enters the Lung, it causes *Fan* (restlessness/irritability). When Fire pathogen enters the Kidney, it causes *Zao* (agitation/restlessness). When both Fan and Zao occur in the upper body, it is because the Kidney (Child) connects with the Lung (Mother). The hair becomes moist like oil, and panting does not cease; this generally indicates the exhaustion of Lung Qi. The nose is the external manifestation of the Lung, and Lung Qi communicates with the nose. Coarse breathing from the nose indicates pathology in the Lung. Hair is the surplus of Blood, governed by Kidney Qi. Hair moist like oil indicates that Fire is forcing Kidney Water to the highest point, signifying that Water is about to be exhausted. Zhang Zhongjing considers moist hair and severe panting as signs of Lung exhaustion, also referring to the Kidney. Although hair is located at the highest point of the head and belongs to the Kidney, the Lung is the highest of the Five Viscera, so stating Lung exhaustion implies Kidney exhaustion as well. Generally, the Lung and Kidney are connected; if the Lung is already exhausted, the Kidney's exhaustion is known without saying. One might ask: Fan is caused by the Heart, and Zao is caused by the Heart. Why is Fan attributed to the Lung and Zao to the Kidney? The Heart is the Ministerial Fire (Monarch Fire). It connects with pathogenic heat, communicating up and down. Heat dries Metal (Lung) and depletes Water (Kidney), leaving only Fire remaining. Thus, the Lung, Kidney, and Heart combine to manifest as Fan and Zao. Although Fan manifests in the Lung and Zao in the Kidney, it is actually caused by Heart Fire. If Fan and Zao are caused by retained food, Zhizi Dahuang Tang (Gardenia and Rhubarb Decoction) should be used.
The response states: The Foot-Yangming Meridian is the Stomach. Is there such a statement? Shaoyang disease begins entering from the skin and hair, originating from the Lung. The Lung governs voice; when pathogen enters the Heart, it manifests as speech abnormalities. The Stomach corresponds to Wu Earth, which transforms into Fire, descending to connect with the Kidney and Liver.
In exterior syndromes of Shanghan (Cold Damage), there is fever, aversion to cold, and thirst, similar to interior excess syndromes. However, accompanied by headache, body heat, eye pain, nasal dryness, and inability to sleep, Baihu Tang (White Tiger Decoction) is indicated. This is a Yangming Meridian disease. In Zhengyang Yangming Qi-level disease, the pulse is surging and large, initially without tangible pathogens. In miscellaneous disease interior syndromes, there is fever, aversion to heat, and thirst. Only red eyes indicate pathology in the Zang organs. Insufficiency of Hand-Taiyin Lung fails to manage and lead the Yang Qi. Treatment should prioritize herbs such as Gouqi (Lycium Fruit), Sheng Dihuang (Rehmannia Root), and Shu Dihuang (Prepared Rehmannia Root). If the pulse is extremely surging and large, hematemesis may occur first, indicating a prior tangible pathology.
If Qi-level disease is in the exterior, mistakenly using blood-invigorating or blood-nourishing drugs causes no harm, as it benefits Yin to stabilize Blood. If Blood-level disease is in the interior, mistakenly using Qi-regulating drugs, such as Baihu Tang, is incorrect, as it drains the Lung and damages Yin.
