种痘后，断不再出，间有出者，名曰小痘，非真痘也。犹之天花之后，亦有水痘。必先
发热一两日，然后发出，仍亦灌水，其中或有数颗略大，亦似灌浆，痘脚亦似有淡淡红线，
但六七日必结靥，靥薄如纸，万无妨碍，幸勿误听人言，认为再出。
其有先天毒盛，发泄未清，出麻疹时必密，延医用一二发表之剂，疏解之即安然无事。
间有痘后即出麻疹等类，亦须延医治之，非恐大碍，特要孩童不致辛苦耳。
又间有结痂后，臂上痘痂之旁红肿，略类痘 ，此固万中无一。宜用豆心渣，即豆腐
渣，或三豆散、紫花地丁、芙蓉膏，四围敷之，留顶勿敷，使其毒由顶出。忆予所种，惟常
博何公梦 少君，又本坊崔渭生令媛，及中协兵弁张耀清之孙有此，按药治之，无不立效。
十数年来，种小儿以万计，所见者仅三人，此外不复有矣。
或腠理气血凝结，致枝节生疮，用棉茧散敷之即愈。无论诸疮，如湿烂用金华散糁之，

或问，天花忌抓破，此独不忌，何也？予曰∶此原是针刺法，毒以刺而引出，刺且不妨
，抓破何害。
又问，取鲜浆时，于取浆之小儿有妨碍否？曰∶予已试验诸千万人，俱未见其有妨碍也
。其所以疑有妨碍者，缘种痘之人，见有好痘，捏破痘浆，盗以作种，其取浆之时，或手力
太重，或捏入太深，或浆水未灌满而取之非其时，或筋脉有关而取之非其处，如是，则或致
有碍耳。若牛痘之法则不然，俟其八九日，灌浆满足，轻轻点取，于己无损，于人有益，何
乐而不为乎。盖痘之患在毒，痘浆既满，则毒已尽泄，取之得法，断然无碍。且予之行此，
亦不过以善方济人耳。若损此而益彼，即予亦不肯为也。
遇有抓破者，系在第七日以前，仍必灌复浆水。如在八、九日以后，则不能灌复，然其

以上各条，皆予所亲试而立效者，引无不出，出无不佳，不患后灾，不忧复发。以医痘
至难之事，今变而为至易，莫非上苍爱怜赤子有意使然？夫父母之于子，未有不欲其以生、
以长、以至成人，顾听其自出天花。症有险易，医有贤愚，悬悬莫必，孰若趁其毒之未发，
引而出之，不费一钱，不受一吓，何等放心，何等快意耶！所愿为父母者，深信勿疑，同志
者广为传布，此则予之浓望，亦凡为父母者所浓望也夫。
种痘之后，通常不会再出天花，偶尔有出的，称为“小痘”，并非真正的天花。这就好比出过天花之后，有时也会出水痘一样。这种“小痘”必须先发热一两天，然后才发出来，仍然会化脓，其中可能有几颗稍微大一些，看起来也像在灌浆，痘根周围也有淡淡的红线，但六七天必定结痂，痂皮薄如纸张，绝对不会造成妨碍，希望不要误听他人的话，认为这是再次出痘。
那些先天胎毒旺盛，发泄不彻底的，在出麻疹时皮疹一定很密集，请医生使用一两剂发表（发散表邪）的药物，疏风解表后即可安然无事。偶尔也有出完痘后又出麻疹等情况的，也必须请医生治疗，并不是担心有大碍，只是要让孩童少受些痛苦罢了。
又偶尔有结痂后，手臂上痘痂旁边出现红肿，略微类似痘疮感染的情况，这确实是万中无一的。适宜用豆心渣（即豆腐渣），或者三豆散、紫花地丁、芙蓉膏，敷在红肿四周，留出顶部不要敷，使毒素从顶部排出。回忆我所接种的人中，只有常博何公梦少君、本坊崔渭生的女儿，以及中协兵弁张耀清的孙子有过这种情况，按照药物治理，没有不立即见效的。十多年来，给小儿种痘数以万计，见到的仅有三人，此外再也没有了。
如果是腠理气血凝结，导致肢体生出疮疡，用棉茧散敷贴即可痊愈。无论何种疮疡，如果湿烂，用金华散撒布；如果疮口干燥，则用猪油调和敷贴；如果生瘢痕癣疾，烧干陈年牛粪敷贴。
有人问：天花忌讳抓破，唯独这个不忌讳，为什么呢？我说：这原本就是针刺的方法，毒素通过针刺引出，针刺尚且不妨害，抓破又有什么害处呢？
又问：采取鲜痘浆时，对取浆的小儿有妨碍吗？回答说：我已经试验了成千上万的人，都没有见到有什么妨碍。之所以怀疑有妨碍，是因为种痘的人，看到好的痘浆，捏破痘浆盗取作为种子，在取浆的时候，要么手力太重，要么捏入太深，要么痘浆未灌满就取，时机不对，要么筋脉受阻却在不合适的地方取，像这样，才会导致妨碍。如果是牛痘法则就不是这样，等到八九天，灌浆饱满，轻轻点取，对自己没有损害，对他人有益，有什么不高兴做的呢？大概痘患在于毒素，痘浆既然满了，毒素已经全部泄出，取法得当，绝对没有妨碍。而且我施行这种方法，也不过是用良方救济世人罢了。如果损害这个而增益那个，即使是我也不肯做。
如果遇到被抓破的，是在第七日以前，仍然必须灌复浆水。如果在八、九日以后，就不能灌复了，然而其毒素已经被引动，泄破也没有妨碍。有的随后就会结痂。如果成脓不干，用武夷茶煎浓汤清洗，或者用黄豆皮煎水洗，或者用胭脂膏、鲫鱼膏、蜡梅油贴敷，都可以。如果成脓而不能合口，用生肌散撒布，外洋原有的药水、药膏治疗此症立竿见影，因为不能经常得到，所以不记录。
以上各条，都是我亲自试验并立即见效的，引导出来的没有不出来的，出来的没有不好的，不用担心后患，不必忧虑复发。以医痘这件极难的事，现在变得极易，莫非是上天怜爱婴儿有意如此？父母对于子女，没有不希望他们生存、成长直至成人的，与其听任他们自然出天花，病症有险有易，医生有贤有愚，悬心不定，不如趁其毒素未发之时，引导而出，不费一文钱，不受惊吓，何等放心，何等痛快啊！希望做父母的深信不疑，志同道合者广为传播，这是我的殷切期望，也是所有做父母的殷切期望啊。
After vaccination (smallpox inoculation), smallpox generally does not occur again. Occasionally, it may appear, known as "small pox" (minor eruption), which is not true smallpox. This is similar to how chickenpox may occur after one has had smallpox. It must first present with fever for one or two days before erupting, and it will still suppurate. Among them, a few may be slightly larger, resembling pus-filling, and the base of the pustules may show faint red lines. However, they will scab over within six to seven days; the scabs are thin as paper and pose absolutely no danger. Do not mistakenly listen to others and believe this is a recurrence.
For those with excessive congenital toxicity that has not been fully expelled, when measles erupts, the rash will necessarily be dense. Consulting a physician to administer one or two diaphoretic agents (formulas to induce sweating and release the exterior) to disperse and resolve the pathogen will result in safety and peace. Occasionally, measles or similar eruptions may follow vaccination; these also require medical treatment, not because there is a major concern, but to spare the child from suffering.
Occasionally, after scabbing, redness and swelling may appear beside the scabs on the arm, somewhat resembling infected pustules. This is indeed one in ten thousand cases. It is appropriate to use bean dregs (i.e., tofu residue), or San Dou San (Three Bean Powder), Viola yedoensis (Viola), or Hibiscus mutabilis ointment, applying it around the periphery of the swelling, leaving the top uncovered to allow the toxin to exit from the apex. I recall that among those I vaccinated, only Mr. He Mengshaojun (son of Duke He of Changbo), Miss Cui Weisheng's daughter from our neighborhood, and the grandson of Zhang Yaoqing, a soldier officer, experienced this. Treating them with the prescribed medicines yielded immediate results. Over the past decade, I have vaccinated tens of thousands of children, and I have encountered this condition in only three individuals; it has not occurred otherwise.
If qi and blood stagnation in the interstices leads to sores on the limbs, applying Mian Jian San (Cocoon Powder) will cure it. For any sores, if wet and ulcerated, sprinkle Jinhua San (Jinhua Powder); if dry, apply with lard; if scarlet lichen or tinea develops, apply burnt aged cow dung.
One might ask: Smallpox is contraindicated to be scratched open, yet this method is not. Why? I say: This is originally an acupuncture-like method; toxins are drawn out by pricking. If pricking is harmless, what harm could scratching cause?
Another asks: Is extracting fresh pus harmful to the child from whom it is taken? I reply: I have tested this on tens of millions of people and have never seen any harm. The suspicion of harm arises because some vaccinators, seeing good pustules, would squeeze them open to steal the pus for inoculation. During extraction, if the force was too strong, the needle inserted too deeply, the pus was taken before filling, or the location was inappropriate due to meridian blockage, then harm might occur. However, the method for cowpox is different. Wait until the eighth or ninth day when the pustule is full, extract gently, and there is no harm to oneself and benefit to others. Why would one not do it? The danger of smallpox lies in the toxin; once the pustule is full, the toxin is fully discharged. With proper technique, there is absolutely no hindrance. Moreover, my practice of this is merely to help people with good prescriptions. If it harmed one to benefit another, even I would not do it.
If a pustule is scratched open before the seventh day, re-inoculation with pus water is still necessary. If it occurs after the eighth or ninth day, re-inoculation is impossible, but since the toxin has already been activated, rupture causes no harm. Some may scab over subsequently. If suppuration remains moist, wash with concentrated decoction of Wuyi tea, or decoction of soybean skin, or apply Zhiyan Gao (Rouge Ointment), Crucian Carp Ointment, or Camellia oil. All are acceptable. If suppuration fails to close, apply Sheng Ji San (Flesh-Generating Powder). Foreign medicinal waters and ointments are effective for this, but since they are not always available, they are not recorded here.
All the above points are those I have personally tested and found effective. Induced eruptions always appear, and appearances are always favorable. There is no worry of later disasters or recurrence. Medical treatment of smallpox is extremely difficult, yet now it has become extremely easy. Could this not be Heaven's compassion for infants? Parents desire their children to survive, grow, and reach adulthood. Rather than letting nature take its course with smallpox—where severity varies, doctors vary in wisdom, and outcomes are uncertain—it is better to guide the toxin out while it is unmanifested. It costs nothing, causes no fright, and brings such peace of mind and joy! I hope parents believe firmly without doubt, and like-minded individuals spread this widely. This is my earnest wish, and indeed the earnest wish of all parents.
