手太阴肺经的本病。症状如前所述。初起时咽喉干燥且无痰，七八日后突然痰声漉漉，甚至出现气喘急促、心烦意乱。这必定是由于误治或病情拖延日久，导致肺火炽盛，机体引水来自救，汇聚五液而化为痰。此时急需用三降龙丹主治。忌用一切苦燥化痰药，如牛黄、胆南星、贝母等药物。尤其不可使用冰片、麝香吹喉的药物，以免助长燥邪。如果初起时就多痰涎，且挟有风火的，不在此例。
这是白喉极危重的证候。人们只知道痰声漉漉，便求助于胆南星、牛黄；看到气喘急促不安，便指望贝母、葶苈子见效。一旦尝试无效，反而重用这些药物，最终导致痰喘更加严重，束手无策，于是认为此病无法医治。却不知道此证纯属太阴燥火炽盛，肺中津液枯竭至极，火势如同燎原，吸聚周身阴液以自救。于是龙雷之火（相火），随着肾水上逆，驱赶一切阴浊之气，壅塞在喉咙之间，全部化为痰。这种痰实际上是阴火冲激而成的，所以非大剂量的清凉合甘咸寒药物不能使其下降。三降龙丹是引导龙火归海的药物。龟板、牡蛎、真珠母获得至静之精气，介类药材能潜阳，所以名为“三降”。冬地、西洋参专门保护肺中津液；阿胶、白芍兼能引导龙雷之火下行；石膏直接清解燥火，坠除一切热痰；犀角通利喉咙，载诸药下行；旋覆花、竹茹用以代替水煎煮，使药力沉重而不滞涩，更能疏通经络隧道。大概此症为白喉，或因误治，或因迁延日久，必然会出现的病症。不明白治疗方法，最容易耽误病情。我的长女曾患此病，咽干音哑，气喘急促，心烦意乱，痰声漉漉如潮水般汹涌，大便泄泻。张氏所列的不治之候，她已占了八项，竟然靠服用此方，每日三剂而获效。服一剂后大便停止，气喘稍安；服两剂后痰声消失。世间的医生不知道病源根本，每逢痰喘，都以牛黄、胆南星为主药。不知道这两味药是足厥阴肝经和足少阳胆经消除痰火的专门药物，与此症风马牛不相及。而且苦味能助燥，也在禁忌之列。其他如贝母、葶苈子辛燥，更不必说了。如果初起时就多痰涎，挟有少阳、少阴的风火标病，那么消痰降火门中的方法自然适用。阴药不可乱投。其中的关键窍要，亟需领会。
The primary disease of the Hand-Taiyin (Lung) channel. The symptoms are as described previously. At the onset, there is dryness in the throat with no phlegm; after seven or eight days, sudden gurgling sounds of phlegm appear, and it may even progress to panting, shortness of breath, and irritability. This must be due to mismanagement or prolonged delay, causing excessive Lung Fire (excessive heat in the Lung organ), leading the body to draw in fluids for self-rescue, gathering the five fluids to transform into phlegm. In this situation, Sanjiang Longdan (Three-Descent Dragon-Subduing Pill) should be used urgently as the main treatment. All bitter-dry phlegm-resolving medicines, such as Niuhuang (Calculus Bovis), Danshenxing (Arisaema cum Bile), Lou (Trichosanthes Radix), and Bei (Fritillariae Bulbus), are contraindicated. Especially, one must not use throat-powdering medicines containing Bingpian (Borneolum Syntheticum) and Shexiang (Moschus) to assist dryness. If there is abundant saliva and phlegm from the onset, accompanied by Wind-Fire, this case does not fall under this category.
This is an extremely severe condition of Baihou (Diphtheria). People only know of the gurgling phlegm sound and seek help from Danshenxing and Niuhuang; seeing panting and restlessness, they expect efficacy from Lou and Tingli (Semen Lepidii). When these attempts fail, they instead increase the dosage, ultimately resulting in worsened phlegm and panting, leaving them helpless, and thus resigning themselves to the belief that the disease is incurable. They do not realize that this syndrome is purely due to excessive Taiyin Dryness-Fire, with Lung fluids exhausted to the extreme. The momentum is like a prairie fire, sucking in Yin fluids from the entire body for self-rescue. Consequently, Longlei Fire (Ministerial Fire associated with Kidney) follows Kidney Water upward, driving all Yin turbidity to obstruct between the throat and larynx, transforming everything into phlegm. This phlegm is actually formed by the衝击 (impact/irritation) of Yin-Fire. Therefore, only large doses of cooling combined with sweet-salty-cold medicines can cause it to descend. Sanjiang Longdan is a medicine that guides the Dragon Fire back to its sea (Kidney). Guiban (Testudinis Carapax et Plastrum), Muli (Concha Ostreae), and Zhenzhumu (Margaritifera Haliotidis) possess the essence of supreme stillness; shellfish-type herbs can subdue Yang, hence named "Sanjiang" (Three Descents). Dongdi (Radix Ophiopogonis processed with Rehmannia), Xiyangshen (Panax quinquefolius Radix) specifically protect Lung juice; Ejiao (Colla Corii Asini) and Baishao (Radix Paeoniae Alba) simultaneously guide the descent of Longlei Fire; Shigao (Gypsum Fibrosum) directly clears Dryness-Fire and sinks all Phlegm-Heat; Xijiao (Rhinocerotis Cornu) unblocks the throat and carries the various medicines downward;uanfu (Flowers Inulae) and Zhuru (Bambusae Caulis in Taenia) are used instead of water for decoction, making the heavy medicines non-stagnant and further unblocking the meridians and collaterals. Generally, this condition arises inevitably in Baihou, whether due to mismanagement or prolonged duration. Failing to understand the treatment method is most likely to cause errors. My eldest daughter once suffered from this illness: dry throat, hoarseness, panting, irritability, gurgling phlegm sounds like surging tides, and diarrhea. She exhibited eight out of the nine untreatable signs listed by Zhang Shi. Yet, she recovered by taking this prescription, three doses daily. After one dose, the diarrhea stopped, and panting eased slightly; after two doses, the phlegm sounds disappeared. Physicians of the world, unaware of the root cause, always take Niuhuang and Danshenxing as primary medicines for every case of phlegm and panting. They do not know that these two substances are specialized medicines for eliminating Phlegm-Fire in the Foot-Jueyin (Liver) and Foot-Shaoyang (Gallbladder) channels, having nothing to do with this syndrome. Moreover, bitter flavors can assist dryness and are also contraindicated. Other herbs like Bei and Tingli, being acrid and drying, are even less suitable. If there is abundant saliva and phlegm from the onset, accompanied by Shaoyang and Shaoyin Wind-Fire manifesting diseases, then the methods in the chapter on resolving phlegm and descending fire are naturally applicable. Yin-nourishing medicines must not be administered indiscriminately. The key insight here must be promptly grasped.
