叙曰∶小儿壮热，呵欠烦闷，时发惊悸，或吐或泻，手足时冷，面颊腮赤，嗽嚏者，为
痘证也。盖痘出于五脏，由内达外，是以各显其证。呵欠烦闷，肝之证也。时发惊悸，心之
证也。或吐或泻，手足时冷者，脾之证也。颊赤嗽嚏，肺之证也。钱氏谓独有肾脏无证，此
大不然，若腰痛喜寐，则肾之证矣。五脏之证尽显者，其痘必多，但显一二证者，其痘必少。
魏氏以痘本于淫火，其言高出前古，虽其主方近于执一，然录古人一十四方，则示人以变通
也可知矣。今世之医，率以是短之，使诸子者并作于九原，昆遇魏氏则北面而师之，遇钱，
陈则肩随而已。所以然者，二子之资不及魏也。兹考群方，则以百家而出入之，初不拘拘于
三子矣。
升麻 葛根（各二钱） 白芍药（一钱半） 甘草（一钱）
小儿初间发热壮盛，为风寒，为痘疮，莫能的辨，此方稳当，宜主用之。
表热壮盛，此邪实于表也。经曰∶轻可以去实，故用升麻、葛根以疏表，甘草佐之，可
以和在表之气。芍药佐之，可以和在表之荣，去其实邪，和其营卫，风寒则解，痘疹则出，
诚初间之良剂也。如至四五日，痘中夹疹者，亦此方主之。疹散，只根据常法治痘。
紫苏 陈皮 半夏 茯苓 干葛 前胡 桔梗（各一钱） 甘草（五分） 人参（七分）
风寒壮热，体重头痛，痰嗽壅盛者，此方主之。
风寒客于外，故用紫苏、干葛以发表。痰嗽壅于内，故用半夏、前胡、桔梗、陈皮、茯
苓以安里。邪去之后，中外必虚，人参、甘草急固其虚。此则表和而痘易出，里和而气不虚，
表
序言说：小儿出现高热，打哈欠、烦躁闷乱，时常发生惊悸，或者呕吐或腹泻，手足时而发冷，面颊和腮部发红，咳嗽打喷嚏的，这是痘证的表现。大概痘疮源于五脏，由体内达于体表，因此各脏腑会显现相应的证候。打哈欠、烦躁闷乱，是肝脏的证候。时常发生惊悸，是心脏的证候。有时呕吐有时腹泻，手足发冷的，是脾脏的证候。面颊发红、咳嗽打喷嚏的，是肺脏的证候。钱乙（钱氏）认为唯独肾脏没有证候表现，这非常不对，如果有腰痛且喜欢睡觉的症状，那就是肾脏的证候了。五脏的证候都完全显现出来的，其痘疮必然很多；只显现一两个证候的，其痘疮必然很少。魏氏认为痘疮本源于淫火（过盛的火热之邪），他的言论高出前人古论，虽然他所主张的主方有些拘泥单一，但他收录了古人的十四个方剂，这就向人们展示了灵活变通的道理。当今的医生，往往因此指责他，假如让这几位前辈医家复活，我吴昆遇到魏氏则会行北面拜师之礼，遇到钱乙、陈文中则只能追随其后罢了。之所以这样，是因为钱、陈二位的资质不及魏氏。现在考证各方，则是综合百家学说并加以出入变化，起初不再拘泥于这三位医家了。
升麻、葛根（各二钱）、白芍药（一钱半）、甘草（一钱）。
小儿初期发热壮盛，无论是风寒还是痘疮，难以辨别时，此方稳妥得当，适宜作为主方使用。
表热壮盛，这是邪气实于体表。《内经》说：轻清的药物可以去实邪，所以用升麻、葛根来疏解表邪，甘草辅助它，可以调和在表之气。芍药辅助它，可以调和在表的营气，去除实邪，调和营卫，风寒得以解除，痘疹得以发出，这确实是初期的良方。如果到了第四五日，痘疮中夹杂疹子的，也用此方主治。疹子消散后，只需按照常规方法治疗痘疮。
紫苏、陈皮、半夏、茯苓、干葛、前胡、桔梗（各一钱）、甘草（五分）、人参（七分）。
风寒导致高热，身体沉重头痛，痰嗽壅盛严重的，此方主治。
风寒客居于体表，所以用紫苏、干葛来发表散邪。痰嗽壅塞于体内，所以用半夏、前胡、桔梗、陈皮、茯苓来安顿里气。邪气去除之后，表里必然虚弱，用人参、甘草紧急固护其虚损。这样则表气和顺而痘疮容易发出，里气和顺而正气不虚，表……
Preface states: When a child presents with high fever, yawning, restlessness and oppression, occasional palpitations and fright, vomiting or diarrhea, coldness of the hands and feet at times, redness of the cheeks and malar area, coughing, and sneezing, this is indicative of Smallpox (Dòuzhèng). Generally, smallpox originates from the Five Zang Organs and manifests from the interior to the exterior; therefore, each organ displays its corresponding signs. Yawning and restlessness are signs of the Liver. Occasional palpitations and fright are signs of the Heart. Vomiting or diarrhea accompanied by cold extremities are signs of the Spleen. Red cheeks, coughing, and sneezing are signs of the Lung. Qian Yi (Qian Shi) claimed that only the Kidney has no specific signs, which is greatly incorrect. If there is lower back pain and a preference for sleep, these are signs of the Kidney. When signs of all five Zang organs are fully manifested, the eruption of pustules will be abundant; when only one or two signs are manifested, the eruption will be sparse. Wei believed that smallpox originates from excessive fire pathogenic factors. His theory surpasses ancient predecessors. Although his main prescription approach was somewhat rigid, by recording fourteen ancient prescriptions, he demonstrated flexibility to practitioners. Modern physicians often criticize him on this account. If those past masters were resurrected, I, Wu Kun, would bow in submission and take Wei as my teacher, while regarding Qian and Chen, I would merely follow behind them. The reason is that the scholarly attainment of Qian and Chen did not match that of Wei. In examining various prescriptions here, I synthesize insights from a hundred schools, varying and adapting them, without being strictly bound to these three masters.
Shengma (Cimicifugae Rhizoma), Gegen (Puerariae Lobatae Radix) (each 2 qian); Baishao Yao (Paeoniae Radix Alba) (1.5 qian); Gancao (Glycyrrhizae Radix et Rhizoma) (1 qian).
When a child initially presents with vigorous fever, and it is difficult to distinguish between Wind-Cold and Smallpox, this prescription is safe and appropriate, suitable for primary use.
Vigorous heat at the Exterior indicates excess pathogenic factors at the surface. The Classics state: "Light substances can dispel excess." Therefore, Shengma and Gegen are used to vent the Exterior, assisted by Gancao to harmonize Qi at the surface. Shaoyao assists to harmonize Ying (Nutritive Qi) at the surface, dispelling excess pathogens and harmonizing Ying and Wei (Defensive Qi). Thus, Wind-Cold is resolved, and smallpox/rash erupts. This is indeed an excellent formula for the initial stage. If by the fourth or fifth day, rashes are mixed with smallpox pustules, this formula is also indicated. Once the rash dissipates, treat the smallpox according to standard methods.
Zisu (Perillae Folium), Chenpi (Citri Reticulatae Pericarpium), Banxia (Pinelliae Rhizoma Preparatum), Fuling (Poria), Gange (Puerariae Lobatae Radix), Qianhu (Peucedani Radix), Jiegeng (Platycodonis Radix) (each 1 qian); Gancao (Glycyrrhizae Radix et Rhizoma) (0.5 qian); Renshen (Ginseng Radix et Rhizoma) (0.7 qian).
For cases of Wind-Cold causing high fever, heavy body, headache, and severe phlegm-cough congestion, this formula is indicated.
Wind-Cold lodging externally necessitates Zisu and Gange to release the Exterior. Phlegm-cough congested internally necessitates Banxia, Qianhu, Jiegeng, Chenpi, and Fuling to settle the Interior. After the pathogen is expelled, both the Exterior and Interior become deficient; Renshen and Gancao urgently secure this deficiency. In this manner, the Exterior Qi becomes harmonious, facilitating the eruption of smallpox; the Interior Qi becomes harmonious, preventing depletion of Zheng Qi (Upright Qi), and the Exterior...
