夫痘胎毒也，伏于有形之始，因感而发，为生人所不能免，然其发也，或染时气
，或感风寒，或因饮食，或由惊恐，以病引病，为患多端，更改莫测，且其间顺吉者
少，险逆者多，有千方百计而不能冀其愈于万一者，此其所以为难也，古有种痘一法
起自江右，达于京畿，究其所源，云自宋真宗时，峨眉山有神人出，为丞相王旦之
子种痘而愈，遂传于世，其说虽似渺茫，然以理揆之，实有参赞化育之功，因时制宜
之妙，盖正痘感于得病之后，而种痘则施于未病之先，正痘治于成病之时，而种痘则
调于无病之日，自表传裹，由里达表，既无诸证夹杂于其中，复有善方引导于其外，
熏蒸渐染，胎毒尽出，又何虑乎为患多端，更改莫测，以致良工束手于无可如何之地
耶，此诚去险履平，避危就安之良法也，然种痘一科，多口传心授，方书未载，恐后
人视为虚诞之辞，相沿日久，无所考稽，使至理良法，竟置无用之地，神功湮没，岂
不大可惜哉，今将种痘一法，细加研究，审度精详，纂辑成书，永垂千古，庶为种痘
之津梁，咸登赤子于寿域也。
心火灼伤肺金，兼受风湿毒邪，皮肤间隐约出现疹点，称为瘾疹。治疗应先使用疏风散湿的羌活散，随后再用消毒饮以彻底清除热毒。
[注释]
瘾疹，是由于心火灼伤肺金，又兼 externally 感受风湿之邪而形成的。发作时必然多痒，颜色红赤，隐隐约约位于皮肤之中，因此命名为“瘾疹”。先用加减羌活散，以疏风散湿；继用加味消毒饮，以清热解毒。表里清利，疹症即可痊愈。

痘疮源于胎毒，潜伏于生命形成之初，因外感诱发，是常人无法避免的。然而其发作，有的感染时气，有的感受风寒，有的因饮食不当，有的由惊恐引起，以病引病，危害多种多样，变化莫测。其中顺证吉兆者少，险逆危重者多，即使千方百计也难以期望万分之一治愈的可能，这就是它的难治之处。古代有一种种痘的方法，起源于江西（江右），传播到京城地区。探究其源头，据说自宋真宗时期，峨眉山有神人出现，为丞相王旦之子种痘而治愈，于是流传于世。这种说法虽然看似渺茫，但从道理上推究，确实有参赞天地化育之功，以及因时制宜的妙处。正痘是在患病之后感染的，而种痘则是在未病之前施行的；正痘是在已成病之时治疗的，而种痘则是在无病之日进行调理的。通过从表传里、由里达表的熏蒸渐染过程，使胎毒尽出，又何须担忧危害多端、变化莫测，致使良医束手无策呢？这确实是去除危险、踏平坎坷，避开危难、趋向平安的好方法。然而种痘这一科，大多口传心授，方书未曾记载，恐怕后人视为虚诞之辞，沿袭日久，无所考证，使得至理良法竟被置于无用之地，神功湮没，岂不大大可惜吗？如今将种痘之法，仔细研究，审慎度量，精详编纂成书，永垂千古，希望成为种痘的津梁，让所有婴儿都能登上长寿之境。
Heart fire scorches the Lung metal, combined with wind-dampness toxicity, causing faint rashes to appear on the skin. This condition is treated initially with Qianghuo San (Notopterygium Decoction) to disperse wind and dampness, followed by Xiaodu Yin (Detoxification Decoction) to completely eliminate residual heat.
[Note]
Yinzhen (Urticaria/Rash), also known as "hidden rash," arises from heart fire scorching the Lung metal, compounded by external contraction of wind-dampness. It invariably presents with intense itching and a red color, appearing faintly within the skin, hence the name "Yinzhen." Initially, Jiajian Qianghuo San (Modified Notopterygium Decoction) is used to disperse wind and dissipate dampness; subsequently, Jiawei Xiaodu Yin (Additive Detoxification Decoction) is employed to clear heat and resolve toxicity. Once both the exterior and interior are cleared, the rash resolves.
(Jiawei Qianghuo San / Modified Notopterygium Decoction): Composition includes: Qianghuo (Rhizoma et Radix Notopterygii), Qianhu (Radix Peucedani), Boheye (Folium Menthae Haplocalycis), Fangfeng (Radix Saposhnikoviae), Chuanxiong (Rhizoma Chuanxiong), Zhike (Fructus Aurantii, stir-baked with bran), Jiegeng (Radix Platycodonis), Chantui (Periostracum Cicadae), Lianqiao (Fructus Forsythiae, heart removed), Sheng Gancao (Radix Glycyrrhizae Preparata), Chi Ling (Poria with Red Core). Decoct with fresh ginger water for oral administration.

Smallpox originates from fetal toxin, latent since the beginning of physical formation, triggered by external pathogens, making it unavoidable for humans. However, its eruption may result from contracting seasonal miasma, catching wind-cold, dietary indiscretion, or fright. One disease invokes another, leading to diverse complications and unpredictable changes. Favorable outcomes are rare, while dangerous and adverse cases are numerous; even with every possible effort, recovery is rarely achieved. This difficulty explains why ancient methods of variolation emerged in Jiangxi (Jiangyou) and spread to the capital region. Tracing its origin, it is said that during the reign of Emperor Zhenzong of Song, a divine being appeared on Mount Emei and inoculated the son of Chancellor Wang Dan, curing him, thus spreading the practice. Although this account seems vague, logically it demonstrates the merit of assisting nature's transformative powers and the subtlety of adapting to times. Natural smallpox occurs after infection, whereas variolation is administered before illness; natural smallpox is treated when disease manifests, while variolation regulates health before disease onset. Through gradual薰蒸 (fumigation/inoculation) from exterior to interior and interior to exterior, the fetal toxin is fully expelled. Why then worry about diverse complications and unpredictable changes that leave skilled physicians helpless? This is indeed an excellent method to remove danger and walk on flat ground, avoiding peril and seeking safety. However, variatology is mostly transmitted orally and recorded in few medical texts. Fearing future generations will dismiss it as absurd, and with long-standing tradition lacking verification, such profound principles and good methods might be rendered useless, their miraculous efficacy lost. Is this not truly regrettable? Now, having carefully studied, meticulously evaluated, and precisely compiled the method of variolation into this book, I hope it will serve as a bridge for variolation, enabling all infants to reach the realm of longevity.
