人因七情六欲，形寒饮冷，损伤肺气，令人咳嗽，胸膈不利，恶寒作热，可服全真丹。若服冷药，则重伤
肺气，令人胸膈痞闷，昏迷上奔，口中吐冷水，如含冰雪，四肢困倦，饮食渐减，此乃冷气入于肺中，侵于膏
肓，亦名冷劳。先服金液丹，除其寒气，再用姜附汤十日可愈，或服五膈散、撮气散，去肺中冷气，重者灸中
府三百壮可愈。（形寒饮冷之伤，初起原不甚深重，医人不明此证，误与凉药，积渐冰坚，致成膏肓之疾。及
至气奔吐冷，寒热无已，不思转手温补，仍与以滋阴退热等剂，以致不起，非是病杀，乃医杀也。）
治验
有一人暑月饮食冷物，伤肺气，致咳嗽胸膈不利，先服金液丹百粒，泄去一行，痛减三分，又服五膈散而
安。但觉常发，后五年复大发，灸中府穴五百壮，方有极臭下气难闻，自后永不再发。（世医不审病因，动云
暑月热气伤肺，一派寒凉，致水气不消，变成大病。）
肺喜暖而恶寒，若寒气入肺或生冷所伤，又为庸医下凉药冰脱肺气，成膈噎病。觉喉中如物塞，汤水不能
下，急灸命关二百壮，自然肺气下降而愈。（噎病之多死者，皆由咽中堵塞，饮食不进，医人畏用热药，多用
寒凉润取其滋补，焉能得生，用先生灸法甚妙，奈人不能信用，何哉。）
又有肺寒一证，令人头微痛，多清涕，声哑，恶寒，肩
背拘挛，脉微浮紧，当服华盖散，重则姜附汤，忌冷物。此证不可误认作痨证治，故表而出之。（肺寒之证，
世医不识，不能用温散，但用桑皮、贝母、麦冬、玉竹等味壅住寒邪，做成弱证者多矣。）
人因为七情六欲，以及形体受寒、饮食生冷，导致肺气受损，出现咳嗽、胸膈部气机不畅、怕冷并伴有发热的症状，可以服用全真丹。如果误服寒凉药物，则会进一步重伤肺气，导致胸膈部痞塞闷胀、神志昏迷且气逆上冲、口中吐出冷水（感觉像含着冰雪）、四肢困倦乏力、食欲逐渐减退，这是冷气侵入肺中，侵犯膏肓部位，也称为冷劳。应先服用金液丹以祛除寒气，再用姜附汤治疗十日即可痊愈，或者服用五膈散、撮气散，以去除肺中的冷气；病情严重者，可灸中府穴三百壮即可痊愈。（形体受寒、饮食生冷造成的损伤，初起时原本并不深重，但医生不明白这个证候，错误地给予寒凉药物，使得寒气积聚渐如冰坚，最终导致膏肓部位的疾病。等到出现气逆上冲、吐冷水、寒热交替不止的情况时，不思考转为温补疗法，仍然使用滋阴退热的方剂，导致病人死亡，这不是病杀人，而是医生害死人。）
治验案例：
有一个人夏天食用了生冷食物，损伤肺气，导致咳嗽和胸膈部气机不畅，先服用金液丹一百粒，排泄了一次大便，疼痛减少了三分，又服用五膈散后病情安定。但后来觉得经常发作，五年后再次严重发作，灸中府穴五百壮，随后排出极臭的浊气难以闻嗅，从此以后永远不再发作。（世俗医生不审察病因，动不动就说暑月热气伤肺，使用一派寒凉药物，导致水气无法消散，变成大病。）
肺喜欢温暖而厌恶寒冷，如果寒气入肺或因生冷所伤，又被庸医使用寒凉药物使肺气被冰伏凝滞，就会形成膈噎病。感觉喉咙中有物体堵塞，汤水不能咽下，急需灸命关穴二百壮，自然肺气下降而痊愈。（患噎病多死亡的，都是因为咽喉堵塞，饮食无法进入，医生害怕使用热药，多用寒凉滋润的药物来取其滋补作用，怎么能让人生存呢？使用先生的灸法非常奇妙，无奈人们不能信任采用，为什么呢？）
又有肺寒这一证候，使人头部轻微疼痛、流大量清鼻涕、声音嘶哑、怕冷、肩背部拘急挛缩，脉象微浮紧，应当服用华盖散，病情重的服用姜附汤，忌食生冷食物。这个证候不可误认为虚劳证来治疗，所以特别列出加以说明。（肺寒的证候，世俗医生不认识，不能使用温散方法，只用桑白皮、贝母、麦冬、玉竹等味道滋腻的药物壅滞住寒邪，造成虚弱证候的人很多了。）
Humans, due to the seven emotions and six desires, as well as exposure to cold in the body and consumption of cold food and drink, damage the Lung Qi (Lung Energy), leading to cough, discomfort in the chest and diaphragm, aversion to cold with fever. One may take Quanzhen Dan (Complete True Pill). If cold-natured medicines are taken, it will severely injure the Lung Qi further, causing chest and diaphragm fullness and oppression, coma with rebellious Qi rushing upward, spitting out cold water from the mouth (feeling like holding ice and snow), fatigue in the four limbs, and gradual reduction in dietary intake. This is cold Qi entering the Lungs and invading the Gaohuang (Gao-Huang) region, also known as Cold Lao (Cold Consumption). First, take Jinye Dan (Golden Fluid Pill) to eliminate the cold pathogen, then use Jiangfu Tang (Ginger and Aconite Decoction) for ten days to achieve a cure. Alternatively, take Wuge San (Five Diaphragms Powder) or Cuoqi San (Grasping Qi Powder) to remove cold Qi from the Lungs; for severe cases, moxibustion on Zhongfu (LU-1) acupoint for three hundred moxa cones can lead to recovery. (The injury from exposure to cold and consumption of cold food/drink is initially not very deep or severe. However, physicians who do not understand this syndrome mistakenly administer cooling medicines, causing the cold to accumulate and harden like ice, resulting in disease in the Gaohuang region. By the time there is rebellious Qi, spitting of cold water, and unceasing alternating chills and fever, if one does not consider switching to warming and tonifying methods, but instead continues to use yin-nourishing and heat-clearing prescriptions, it leads to death. It is not the disease that kills, but the physician.)
Case Record:
A person consumed cold food during the summer months, injuring Lung Qi, resulting in cough and chest/diaphragm discomfort. He first took one hundred pills of Jinye Dan (Golden Fluid Pill), which resulted in one bowel movement, reducing pain by three parts. Then he took Wuge San (Five Diaphragms Powder), and his condition stabilized. However, he felt frequent recurrences. Five years later, it flared up severely again. Moxibustion was applied to Zhongfu (LU-1) acupoint for five hundred cones. Subsequently, extremely foul-smelling turbid gas was discharged, which was unbearable to smell. After this, the condition never recurred again. (Worldly physicians fail to examine the cause of the disease, often claiming that summer heat damages the Lungs, and thus prescribe a regimen of cold-cooling herbs, causing water qi to fail to dissipate and transforming into a major illness.)
The Lungs prefer warmth and dislike cold. If cold pathogen enters the Lungs or injury occurs from cold/raw foods, and庸医 (quack physicians) use cold-natured medicines to freeze and stagnate the Lung Qi, it results in Geye Bing (Diaphragm and Dysphagia Disease). The patient feels a sensation of obstruction in the throat, unable to swallow soup or water. Urgent moxibustion on Mingguan (Mingguan) acupoint for two hundred cones will naturally cause Lung Qi to descend, leading to recovery. (Most deaths from dysphagia are due to blockage in the throat preventing food intake. Physicians fear using hot-warm medicines and mostly use cold-cooling and moistening agents seeking their nourishing effects; how can life be saved? Using Mr. Dou's moxibustion method is excellent, yet people cannot trust and adopt it. Why?)
There is another syndrome of Lung Cold, which causes slight headache, abundant clear nasal discharge, hoarseness, aversion to cold, stiffness and spasms in the shoulders and back, and a pulse that is slightly floating and tight. One should take Huagai San (Canopy Powder); for severe cases, Jiangfu Tang (Ginger and Aconite Decoction). Cold foods must be avoided. This syndrome must not be mistaken for Lao Zheng (Consumption Syndrome) and treated as such; therefore, it is presented here for clarification. (Physicians of the world do not recognize the syndrome of Lung Cold and fail to use warming-dispersing methods. Instead, they use herbs such as Sangbai Pi (Morus Bark), Beimu (Fritillaria Bulb), Maidong (Ophiopogon Tuber), and Yuzhu (Polygonatum Rhizome), which are cloying and trap the cold pathogen, creating many weak syndromes.)
