夫饮食所以养生，过则伤脾，若过极则亦所以戕生者也，何则？痰火之病，始于水涸，
金伤，金既受伤，则木寡于畏，其不凌脾者鲜矣。以脾受木贼，则运化之机自迟，而复不能
节其饮食，以致伤而复伤。轻则嗳腐吞酸，重则痞满疼痛，病体复加，有此则亦难乎其为治
也。盖欲攻积则妨正，欲温中则动火，过消导则反损脾，三者之法，岂其宜乎？况人藉水谷
之气以为养，土受木贼，则不能运化精微，上归于肺输，布五脏，以养百骸，自是形日减，
肌肉日消，其人即能饮能食，无乃食 而已，更何益耶？此谓调摄之一关也，可不谨哉！
窃谓火病金伤之体，实由敝室陋巷，倘无趋避之策。风狂雨骤，其何以御之耶？盖肺主
，司腠理阖闭，金受火贼，则卫护敛固之令失权，六淫之邪易于侵袭。轻则入于皮肤，但为
嚏唾涕咳诸候，惟以身表温暖，腠理疏豁，不干真气，或可消散。甚则入于经络，表有头痛
发热，身痛脊强，不即发汗，则必入里而为潮汗闭涩满渴等症，
羸之躯，几微之气，而复任此猖狂，虚虚
，是亦促命之杀车槌也，慎之。
气鼓喉而为声，情发心而为言。故曰∶声者肺之韵，言者心之声。且火之病，以水亏火
烁肺金，伤其生化，母令子虚，致水益亏而火益炽，肺愈伤而金益烈，法当滋阴降火以益金
。以言多语急，鼓伤肺窍，则为咳嗽声嘶，且言则呼多吸少，致息不匀，则五脏之气，亦自
愆期矣。所谓肺欲实，先调息，正此之谓，言可多乎？
饮食是用来滋养生命的，但过量则会损伤脾胃，如果过度至极，也会成为戕害生命的原因，为什么呢？痰火这类疾病，起始于肾水枯竭、肺金受伤；肺金既然已经受伤，那么肝木就会缺乏制约，它不侵犯脾土的情况就很少见了。由于脾土受到肝木的克制，其运化功能自然迟缓，再加上不能节制饮食，导致身体再次受损。轻症表现为嗳气带有腐臭味、吞酸，重症则出现心腹痞满疼痛，病情加重，遇到这种情况治疗就很困难了。大概想要攻逐积滞就会妨碍正气，想要温补中焦又会助长火热，过度使用消导药物反而会损伤脾土，这三种治疗方法，难道都适宜吗？况且人依靠水谷的精微之气来滋养身体，当脾土受肝木克制时，就不能运化精微物质，将其上输归于肺，再布散到五脏，以滋养全身骨骼肌肉，从此形体日渐消瘦，肌肉日渐消耗，这样的人即使能喝能吃，也不过是吃了而已，又有什么益处呢？这就是调养摄生的一个关键关卡，能不谨慎吗！
我认为患有火病且肺金受伤的人，实际上就像住在破败的房屋和简陋的巷子里，如果没有躲避的策略，狂风暴雨骤至，又怎么能抵御呢？肺主皮毛，主管腠理的开合，肺金受到火的克制，那么卫外固护的功能就会失去控制，六淫邪气就容易侵袭人体。轻症邪气侵入皮肤，只表现为打喷嚏、流涕、咳嗽等症状，只要身体表面温暖，腠理疏泄通畅，不干扰真气，或许可以自行消散。重症邪气侵入经络，体表出现头痛发热、身体疼痛、脊柱强直等症状，如果不立即发汗解表，邪气就会入里转化为潮热、出汗异常、小便闭塞涩痛、胸腹胀满、口渴等症状。对于这种瘦弱的身躯、微弱的元气，如果再任由邪气猖狂肆虐，造成虚上加虚，这也是催命的刑具啊，一定要谨慎。
气流冲击喉咙而发出声音，情感发自内心而表现为言语。所以说：声音是肺的韵律，言语是心的声音。而且患火病的人，因为肾水亏虚、火热灼烧肺金，损伤了生化之源，母脏（肺）虚弱导致子脏（肾）更虚，致使肾水更加亏虚而火势更加炽盛，肺更加受伤而金气更加燥烈，治法应当滋阴降火以补益肺金。如果言语过多、语速急促，会鼓伤肺窍，导致咳嗽、声音嘶哑，而且说话时呼多吸少，导致呼吸不均匀，这样五脏的气机也会违背正常的节律。所谓“肺喜欢充实，首先要调节呼吸”，正是说的这个意思，言语岂可过多？
Diet is intended to nourish life, but excess damages the Spleen and Stomach; if it reaches an extreme, it becomes a cause of harming life. Why? The disease of Phlegm-Fire (Tan Huo) begins with the depletion of Kidney Water (Shui He) and injury to Lung Metal (Jin Shang). Once Lung Metal is injured, Liver Wood (Mu) lacks restraint, making it rare for it not to invade Spleen Earth (Pi). Because Spleen Earth is attacked by Liver Wood, its mechanism of transportation and transformation naturally slows down. If one fails to regulate diet, the body suffers repeated injuries. Mild cases manifest as belching with a putrid odor and acid regurgitation; severe cases present with epigastric fullness and pain. When the diseased state worsens, treatment becomes difficult. Generally, attacking accumulation harms healthy Qi, warming the Middle Jiao stirs Fire, and excessive use of digestive agents damages the Spleen. Are these three methods appropriate? Moreover, humans rely on the Qi of food and drink for nourishment. When Spleen Earth is attacked by Liver Wood, it cannot transport and transform fine essences to send them up to the Lung for distribution to the Five Zang organs, thereby nourishing the entire body. Consequently, the physique diminishes daily, muscles waste away. Even if such a person can eat and drink, it is merely eating, offering no benefit. This is a critical pass in regulation and preservation; how can one not be cautious!
I believe that individuals suffering from Fire diseases with injured Lung Metal are like those living in dilapidated houses and narrow alleys. Without strategies to avoid or shelter, how can they withstand sudden violent winds and heavy rains? The Lung governs the skin and hair (Mao Li) and controls the opening and closing of the Cou Li (interstices). When Lung Metal is attacked by Fire, the authority of defensive protection and consolidation is lost, making it easy for the Six Excesses (Liu Yin) pathogenic factors to invade. In mild cases, pathogens enter the skin, manifesting only as sneezing, rhinorrhea, sputum, and cough. As long as the body surface remains warm, the Cou Li are open and unobstructed, and the True Qi is not disturbed, the condition may dissipate spontaneously. In severe cases, pathogens enter the meridians, presenting with headache, fever, body ache, and stiffness of the spine. If sweating therapy is not applied immediately, pathogens will penetrate inward, transforming into symptoms such as tidal fever, abnormal sweating, urinary retention and dysuria, abdominal fullness, and thirst. For a emaciated body and faint Qi, allowing such rampant pathogenic activity leads to deficiency compounding deficiency, which is akin to a executioner's hammer hastening death. One must be cautious.
Qi flows through the throat to produce sound; emotions arise from the Heart to produce speech. Thus it is said: Sound is the resonance of the Lung; Speech is the voice of the Heart. Furthermore, in Fire diseases, due to Kidney Water deficiency and Fire scorching Lung Metal, the source of generation and transformation is damaged. The Mother (Lung/Metal) becoming deficient causes the Child (Kidney/Water) to become deficient, leading to further depletion of Water and intensification of Fire, further injuring the Lung and exacerbating the dryness of Metal. The therapeutic method should be to nourish Yin and descend Fire to benefit Metal. Excessive talking and rapid speech damage the Lung orifices, causing cough and hoarseness. Speaking involves more exhalation than inhalation, leading to irregular breathing, which causes the Qi of the Five Zang organs to deviate from their normal rhythm. It is said, "The Lung desires fullness; first regulate the breath." This is precisely what is meant. How can speech be excessive?
