气不续。必发而为喘。夫渴与喘。实证也。起于泄泻之后。斯为津液暴亡而渴。阴气暴逆而喘。

身发壮热。毛直皮燥。睡卧不宁。腮红睛赤。烦渴腹胀。便秘喘急。皆实热证。而复见呕吐者。
此热毒在内。不得伸越。或为寒冷所搏。乳食不节。冷热相拒。则上逆而为呕吐。病机所谓诸逆

气虚导致的痘疹，有时因为饮食生冷，调理不当，损伤脾胃，从而形成泄泻。津液下陷，虚火上亢，必然引发口渴。元气下陷，虚阳上壅，下焦之气不能接续，必然引发气喘。口渴和气喘看似实证，但起于泄泻之后，这是津液突然亡失而口渴，阴气突然逆乱而气喘。因此治疗口渴适宜用钱氏白术散，如果渴和泻不止，则使用钱氏异功散。治疗气喘适宜用独参汤，若无效，也使用钱氏异功散。大便干结的，少量给予生脉散调理。气喘、口渴兼有泄泻的，选用陈氏木香散或异功散。如果发展到烦躁闷乱、腹胀，毒邪内攻，闭目胡言乱语的情况，这名叫“失志”。庸医不仔细考察，错误地认为是实证，而给予耗气的药物，会加速死亡。怎么会有实热导致口渴、气机壅滞导致气喘，且产生于泄泻之后的呢？
身体发出高热，毛发直立，皮肤干燥，睡卧不安，腮部发红，眼睛赤红，烦躁口渴，腹胀，便秘，气喘急促，这些都是实热证。但如果又出现呕吐，这是因为热毒在体内，无法向外发散，或者被寒冷所侵袭，乳食不节制，冷热相互排斥，从而向上逆乱导致呕吐。这就是病机所说的各种向上冲逆的症状，都属于火的原因。治疗应当升提发散，兼用辛味药以疏散它，如升麻汤加生姜、橘皮之类。呕吐和气逆严重的，再加猪苓、泽泻引导其下行。又有泄泻兼见的情况，看起来像虚证，然而是因为热毒郁结旺盛，熏灼脾胃，不能向外透达，那么毒邪就从下面下陷，寻找孔窍而出，也应当升提发散，使热毒从外部解除，内部的泄泻自然停止。如果有食积则兼用消导药，如枳壳、山楂之类。又有不想吃东西的情况，看起来像内部虚弱，不知道是郁热在体内，无法向外发散，二便闭塞，腠理阻塞，热毒壅遏，腹胀满急，不想吃东西，这是必然的趋势。也应当升提发散，引导毒邪到达体表。有热则兼用清热药，如山栀、黄连之类，这样热气有所升发透越，脏腑恢复和平，饮食自然增进。如果错误地在呕吐泄泻的病症中使用丁香、肉桂、半夏等热性药物，在腹胀不想吃东西的病症中使用人参、[缺字]、白术等补益药物，立刻就能致人死亡。其他如龙骨、豆蔻、神曲、[缺字]、缩砂仁，都是治疗热性泄泻的武器（即有害之物）。
In cases of varicella or smallpox due to Qi deficiency, sometimes consumption of raw and cold food, combined with improper regulation, damages the Spleen and Stomach, leading to diarrhea. The descent of Body Fluids (Jin Ye) and the hyperactivity of Deficient Fire result in thirst. The sinking of Yuan Qi and the congestion of Deficient Yang, with the lower Qi failing to continue, result in panting. Although thirst and panting appear as Excess syndromes, their onset following diarrhea indicates that thirst arises from the sudden loss of Body Fluids, and panting from the sudden rebellion of Yin Qi. Therefore, for treating thirst, Qian's Baizhu San (White Atractylodes Powder by Dr. Qian) is appropriate; if thirst and diarrhea persist, Qian's Yigong San (Yi Gong Powder) should be used. For treating panting, Dushen Tang (Single Ginseng Decoction) is suitable; if ineffective, Qian's Yigong San may also be used. In cases where stool is solid, a small amount of Shengmai San (Generate the Pulse Powder) can be given for regulation. For symptoms of panting, thirst, and diarrhea, Chen's Muxiang San (Aucklandia Powder) or Yigong San can be selected. If the condition progresses to restlessness, abdominal distension, internal attack by toxic factors, closed eyes with muttering speech, this is named "Shi Zhi" (Loss of Will/Confusion). Unskilled physicians, failing to examine carefully, mistakenly diagnose it as an Excess syndrome and administer Qi-consuming agents, which accelerates death. How could there be thirst caused by Excess Heat and panting caused by Qi congestion arising after diarrhea?
High fever, erect hair, dry skin, restless sleep, red cheeks, red eyes, irritability, thirst, abdominal distension, constipation, and rapid panting are all signs of Excess Heat. However, if vomiting occurs additionally, it is because heat-toxin is trapped inside and cannot extend outward, or due to invasion by cold, irregular intake of milk and food, causing cold and heat to repel each other, leading to upward rebellion and vomiting. This corresponds to the pathological mechanism stating that various rebellious upward movements belong to Fire. Treatment should involve lifting and dispersing, combined with pungent herbs to scatter the pathogen, such as Shengma Tang (Cimicifuga Decoction) added with fresh ginger and tangerine peel. For severe vomiting and rebellious Qi, Zhuling (Polyporus) and Zexie (Alisma) can be added to guide the pathogen downward. In cases where diarrhea coexists, appearing like a Deficiency syndrome, it is actually due to abundant郁 (stagnant) heat-toxin scorching the Spleen and Stomach, preventing external release, causing the toxin to sink downward and exit through orifices. Treatment should still involve lifting and dispersing to resolve the heat-toxin externally, after which internal diarrhea will cease naturally. If food stagnation is present, digestive aids like Zhike (Bitter Orange Fruit) and Shanzha (Hawthorn Fruit) can be added. In cases of loss of appetite, appearing like internal Deficiency, it is unknown that stagnant heat is trapped inside, unable to extend outward, causing blockage of urination and defecation, obstruction of interstices (Cou Li), and congestion of heat-toxin, leading to abdominal distension, urgency, and loss of appetite. This is an inevitable trend. Treatment should involve lifting and dispersing to draw the toxin to the surface. If heat is present, clearing-heat herbs like Zhizi (Gardenia Fruit) and Huanglian (Coptis Rhizome) can be added, allowing the heat Qi to rise and disperse, restoring harmony to the Zang-Fu organs, and naturally improving appetite. If hot herbs such as Dingxiang (Clove), Rougui (Cinnamon Bark), and Banxia (Pinellia Tuber) are mistakenly used for vomiting and diarrhea, or tonifying herbs such as Renshen (Ginseng Root), [missing character], and Baizhu (Atractylodes Macrocephala Rhizome) are used for abdominal distension and loss of appetite, death will ensue immediately. Others such as Longgu (Fossilized Bones), Doukou (Cardamom Fruit), Qu (Medicated Leaven), [missing character], and Suansha (Amomum Fruit) are weapons against heat-type diarrhea.
