气虚型痘症，有的因为饮食生冷，调理不当，导致损伤脾胃，于是形成泄泻。因此津液下陷，虚火上亢，必然引发口渴；加之元气下陷，虚阳上冲，下焦之气不续，必然引发气喘和口渴，这与喘实证是不同的。然而，起于泄泻之后的症状，是津液突然亡失而口渴，气虚而气喘，怎么会有实热而口渴、气机壅滞而气喘，产生于泄泻之后呢！所以治疗口渴适宜用参苓白术木香散。如果泄泻不止，则使用异功散。治疗气喘适宜用人参定喘汤。如果气喘、口渴且泄泻不止，则使用木香异功散。如果发展到烦闷扰乱、腹胀，这是痘毒内攻，眼睛闭合、自言自语，这已经称为“失志”，如果还认为是实证，是多么荒谬啊！
病症必定以元气为主，元气充实则痘毒容易透出、化解，所以治疗痘症的人，只在虚弱之前保护元气，使其不至于耗散为实证罢了。然而其治疗方法是什么？一是充实腠理，巩固肌表；二是节制饮食，保护脾土。肌表坚固则外陷的祸患不值得忧虑，脾土厚实则下陷的祸患不值得担忧，再加上人参补益的功效，则元首（头部/正气）自然充实。痘症发出时，自然容易成浆，变症不生，结痂顺候了。最禁止使用寒凉荡涤的药物，如大黄、滑石、车前子、生地、鼠粘子（牛蒡子）、紫草、枳壳之类，恐怕它们荡涤润下，从而损伤脾胃，脾胃一旦受伤，则元气从此而下陷，气脱内攻而死，更最禁止使用滑润发散的药剂，如鼠粘子、人牙、蝉蜕、麻黄、干葛（葛根）、升麻、紫草、防风、羌活、荆芥之类，恐怕它们发散太过，从而导致表虚。表一旦虚弱，则元气由此而外耗，塌陷、瘙痒、外剥而死亡，这是谁的过错呢！
In cases of variola (smallpox) with Qi deficiency, some patients suffer from spleen and stomach injury due to improper dietary management involving cold or raw foods, leading to diarrhea. Consequently, body fluids sink downward while deficient fire flares upward, inevitably causing thirst. Additionally, with sinking of primordial Qi and upward rushing of deficient Yang, the Qi in the lower jiao fails to continue, inevitably causing panting and thirst. This differs from excess-type panting. However, symptoms arising after diarrhea are caused by sudden loss of body fluids leading to thirst, and Qi deficiency leading to panting. How could there be thirst due to excess heat and panting due to Qi stagnation arising after diarrhea? Therefore, for treating thirst, Shenling Baizhu Muxiang San (Ginseng, Poria, Atractylodes Macrocephala, and Amomum Powder) is appropriate. If diarrhea persists, Yigong San (Extra Efficacy Powder) should be administered. For treating panting, Renshen Dingchuan Tang (Ginseng Panting-Calming Decoction) is suitable. If panting, thirst, and persistent diarrhea occur simultaneously, Muxiang Yigong San (Amomum Extra Efficacy Powder) should be used. If the condition progresses to mental confusion, restlessness, and abdominal distension, it indicates that the toxin has attacked internally. With eyes closed and muttering to oneself, this is already termed "Shi Zhi" (Loss of Spirit). To still consider this an excess pattern is extremely absurd!
Disease patterns must prioritize primordial Qi. When primordial Qi is substantial, toxins are easily expelled and transformed. Thus, practitioners treating variola must protect primordial Qi before it becomes weak, preventing it from dissipating into an excess pattern. What are the treatment methods? First, strengthen the couli (interstices) and consolidate the muscle surface; second, regulate diet and preserve Spleen Earth. If the muscle surface is solid, there is no need to worry about external sinking complications; if Spleen Earth is substantial, there is no need to fear internal sinking complications. Furthermore, with the tonifying efficacy of Renshen (Ginseng), the head (and upright Qi) will naturally become substantial. When the rash erupts, it will naturally progress to pustule formation without generating complicated symptoms, leading to a smooth scabbing process. One must strictly prohibit cold-natured purgative agents such as Dahuang (Rhei Radix et Rhizoma), Huashi (Talcum), Cheqiancao (Plantaginis Herba), Shengdi (Rehmanniae Radix), Niuzbangzi (Arctii Fructus), Zicao (Lithospermi Radix), and Zhike (Aurantii Fructus Immaturus), lest they purge and moisten downward, thereby damaging the spleen and stomach. Once the spleen and stomach are injured, primordial Qi sinks downward, leading to Qi collapse and internal attack resulting in death. Moreover, one must strictly prohibit slippery and dispersing agents such as Niuzbangzi, Renya (Human Tooth), Chantui (Cicadae Periostracum), Mahuang (Ephedrae Herba), Gange (Puerariae Radix), Shengma (Cimicifugae Rhizoma), Zicao, Fangfeng (Saposhnikoviae Radix), Qianghuo (Notopterygii Rhizoma et Radix), and Jingjie (Schizonepetae Spica), lest excessive dispersion leads to exterior deficiency. If the exterior becomes deficient, primordial Qi dissipates outward, leading to collapse, itching, exfoliation, and death. Whose fault is this!
