（附秽浊）
徐仲光治一儿痘，紫色而不起胀，乃毒盛壅遏也。以紫草、红花、蝉蜕，煎酒，调独圣散服之，又以犀角
地黄治之，红润起胀而愈。
一儿痘，六日稠密紫滞，平陷而不起胀，烦躁闷乱，亦毒盛壅遏也，但分珠脚敛可治。以人中黄，每服三
分，酒调，连二服，色渐红活。又以犀角地黄汤加牛蒡、蝉蜕，痘绽突起胀而愈。
一儿痘血热重，初时纯与凉血解毒，犀角服过二两，石膏五钱一剂者，服过五剂。至十朝，略用参三分托
浆。十二朝外，浆清痂薄，用助托药加棉茧带蛾者七枚，糯米一合，渴时即以麦冬、糯米、棉茧，煎汤饮之。
又发水泡数个，浆疤暗长，灌烂遍身，复用茯苓、苡仁、白芍、黄连、银花、甘草、生地、骨皮、山楂、莲肉、
木通、连翘、牛蒡、荆芥而愈。（清热过重，故元气不能充浆，所以善治者于清热之时，即预为异日催浆之地，
庶不至打成两橛也。）
万世用云∶庚申春，家有顽童，仅十岁，患痘疮症，适仆寓乡之故卢，闻报急归，视其疾不为不急，且傍
有煎炒油腻，欲避莫能，荷育溪（曾世荣也。）疗之。恰七日，疮胀而光泽，偶因舍下有动厕秽触，觉色黯而
神昏，大为惊惧。育溪曰∶毋虑，吾有除秽药，投之必安。不数日，果如其言，遂拜更生。用扣其所用何剂？
曰∶中和汤，即十奇散，如沉、檀等剂而已，余无他巧。（《幼幼心书》。）

Xu Zhongguang treated a child with smallpox. The pustules were purple and failed to rise and swell, indicating excessive pathogenic heat and stagnation. He administered Du Sheng San (Solely Holy Powder) mixed with wine decocted from Zicao (Arnebiae Radix), Honghua (Carthami Flos), and Chantui (Cicadae Periostracum), followed by Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction). The skin turned ruddy, the pustules rose and swelled, and the patient recovered.
Another child presented with dense, purple, and sluggish smallpox lesions on the sixth day, which were flat, depressed, and failed to rise. The child suffered from restlessness and confusion, also due to excessive pathogenic heat and stagnation. However, it was deemed treatable if the distinct "pearl" formation could be observed. Renzhonghuang (Human Middle Yellow) was administered at 3 fen per dose, mixed with wine. After two doses, the color gradually became ruddy and vibrant. Subsequently, Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) was modified with Niubangzi (Arctii Fructus) and Chantui (Cicadae Periostracum). The lesions opened, protruded, and swelled fully, leading to recovery.
In another case of severe blood-heat in smallpox, initial treatment consisted solely of cooling the blood and detoxifying. The patient consumed over 2 liang of Xijiao (Rhinocerotis Cornu) and 5 qian of Shigao (Gypsum Fibrosum) per dose for five doses. By the tenth day, a small amount of Renshen (Ginseng Radix et Rhizoma), 3 fen, was used to support the filling of the pustules. After the twelfth day, as the pus was clear and the scabs thin, supportive tonifying herbs were added, including seven silkworm pupae within cocoons and one he of Nuomi (Oryza Sativa Var. Glutinosa). When thirsty, the child drank a decoction of Maidong (Ophiopogonis Radix), Nuomi (Oryza Sativa Var. Glutinosa), and silkworm cocoons.
Later, several water blisters appeared, and the pus/scabs became dark and stagnant, with ulceration spreading over the body. Treatment with Fuling (Poria), Yiren (Coicis Semen), Baishao (Paeoniae Radix Alba), Huanglian (Coptidis Rhizoma), Yinhua (Lonicerae Japonicae Flos), Gancao (Glycyrrhizae Radix et Rhizoma), Shengdi (Rehmanniae Radix), Guipi (Phellodendri Cortex), Shanzha (Crataegi Fructus), Lianrou (Nelumbinis Semen), Mutong (Akebiae Caulis), Lianqiao (Forsythiae Fructus), Niubangzi (Arctii Fructus), and Jingjie (Schizonepetae Spica) led to recovery. (Excessive use of cold-clearing herbs depleted the Yuan Qi, preventing adequate pus formation. Therefore, skilled practitioners prepare for later stages of pus induction while clearing heat, avoiding disjointed treatment.)
Wan Shiyong stated: In the spring of Gengshen year, my ten-year-old son contracted smallpox. A servant residing in Lu village rushed back upon hearing the news. I examined him and found the condition not urgent; however, greasy fried foods nearby could not be avoided. Heo Yuxi (Zeng Shirong) was consulted. On the seventh day, the lesions were swollen and lustrous. Accidentally exposed to foul odors from a latrine, the lesions turned dark, and the child became comatose and terrified. Yuxi said, "Do not worry. I have herbs to remove turbidity; administration will ensure safety." Within a few days, it proved true, and the child was reborn. When asked about the prescription, he replied, "Zhonghe Tang (Harmonizing Decoction), which is essentially Shiqi San (Ten Wonders Powder), containing Chenxiang (Aquilariae Lignum Resinatum), Tanshen (Santalum Album Lignum), etc., with no other special tricks."
