陈文宿先生云∶痘疹四五日不大便，以肥猪 白水煮熟，切豆大五七块与食之，滋润脏腑，疮痂易落，切不可妄
投宣利之药，恐真气内虚，疮毒入里。如六七日身壮热不大便，其脉紧盛，与三味消毒饮微利之。窃谓∶前症若毒在肌
肉而未能尽发，脉浮而紧者，最宜此药疏解其毒。若脉沉而
紧者，宜用前胡枳壳散疏通毒瓦斯，以绝其源。若口舌咽喉肿痛，疮毒甚也，用射干鼠粘子汤。若大便既通，作渴饮汤，
脾胃气虚也，用人参白术散。凡燥粪在直肠不能下者，宜用猪胆汁导之，忌用疏利之剂，恐复伤胃气，则疮未出者不能
发出，已出者不能贯靥。大抵分辨虚实，当以手足冷热，或饮水饮汤验之。
一小儿大便不通，痘赤作痛，发热作渴，手足并热，此余毒内作，用前胡枳壳散一剂，大便随通，诸症顿退；又与
六味活血散而愈。
一小儿痘疮发热作渴， 赤胀痛，大便秘结，此热毒在内，先用清凉饮一剂，诸症稍退；又用鼠粘子汤一剂，诸症
全退；再用紫草快 汤而贯脓，更用消毒饮而痘靥。
一小儿痘赤狂喘，大便不利，此胃经有热，先君治以犀角地黄汤芹莱汁而痊。
四顺清凉饮 治积热颊赤作渴，四肢惊掣，大便秘涩。
赤芍药 当归 甘草 大黄（各等分）
上每服一钱，水煎。
按∶清凉饮乃苦甘疏泻内热之剂。若热毒在内，大便不通，表无他症，宜用之。连翘饮乃苦寒发表内疏之剂，若表
里实热，烦渴饮冷，大便不通，小便秘结者宜用之，不可过剂。恐妄发则成 烂，妄下则成虚脱也。

陈文宿先生说：患痘疹四五日不大便，可用肥猪肉加清水煮熟，切成豆粒大小的五六块给孩子吃，以滋润脏腑，促使疮痂容易脱落。切不可胡乱投用宣通泻利的药物，恐怕导致体内真气虚弱，使疮毒内陷入里。如果六七日身体高热且不大便，脉象紧盛，可给予三味消毒饮轻微通利。我认为：前述症状若因毒邪在肌肉而未能完全发出，脉象浮紧的，最适合用此药疏解其毒。若脉象沉紧的，宜使用前胡枳壳散疏通毒气，以断绝病源。若口舌咽喉肿痛，说明疮毒严重，应用射干鼠粘子汤。若大便已经通畅，出现口渴想喝汤水的情况，这是脾胃气虚的表现，应使用人参白术散。凡是燥屎在直肠无法排出的，宜用猪胆汁导法通便，忌用疏利攻下的药剂，恐怕再次损伤胃气，导致未发出的痘疮不能透发，已发出的痘疮不能结痂愈合。大抵分辨虚实，应当通过观察手足冷热，或询问是否饮水、饮汤来验证。
有一个小儿大便不通，痘色红赤且疼痛，发热口渴，手足都热，这是余毒在内发作，使用前胡枳壳散一剂，大便随即通畅，各种症状立刻消退；又给予六味活血散而痊愈。
另一个小儿痘疮发热口渴，痘色红赤胀痛，大便秘结，这是热毒在内，先用清凉饮一剂，各种症状稍微消退；再用鼠粘子汤一剂，各种症状全部消退；接着用紫草快斑汤使痘疮化脓，再用消毒饮使痘疮结痂。
还有一个小儿痘色红赤，狂躁气喘，大便不利，这是胃经有热，家父用犀角地黄汤和芹菜汁治疗而痊愈。
四顺清凉饮：治疗积热导致的脸颊红赤、口渴、四肢惊厥抽搐、大便秘涩。
组成：赤芍药、当归、甘草、大黄（各等分）。
用法：每次服用一钱，用水煎服。
按语：清凉饮是苦甘性质的疏泻内热的方剂。若热毒在内，大便不通，体表没有其他症状，适宜使用。连翘饮是苦寒性质、既能发表又能内疏的方剂，若表里实热，烦渴喜冷饮，大便不通，小便短赤涩结者适宜使用，不可过量。恐怕妄用发汗药会导致疮疡溃烂，妄用泻下药会导致虚脱。
消毒饮：荆芥（二钱）、防风、牛蒡子（各一钱五分）、甘草（一钱）。
用法：用水煎煮，酌情服用。

Mr. Chen Wensu said: If a child with smallpox has not had a bowel movement for four or five days, boiled lean pork in plain water, cut into pieces the size of beans (about 5-7 pieces), and let the child eat it to moisten the zang-fu organs, facilitating the falling of scabs. One must absolutely avoid recklessly administering purgative or laxative medicines, lest this deplete the true qi internally and cause the toxin to sink inward. If after six or seven days the body has high fever and no bowel movement, and the pulse is tight and vigorous, administer Sanwei Xiaodu Yin (Three-Ingredient Toxin-Resolving Decoction) to gently promote evacuation. I suggest: For the aforementioned symptoms, if the toxin is in the muscles and has not fully erupted, and the pulse is floating and tight, this medicine is most suitable to disperse and resolve the toxin. If the pulse is deep and tight, Qianhu Zhike San (Peucedanum and Bitter Orange Powder) should be used to unblock the toxic qi, cutting off the source. If there is swelling and pain in the mouth, tongue, and throat, indicating severe toxin, use Shegan Niuzibang Tang (Belamcanda and Burdock Decoction). If the bowel movement has already cleared, but thirst and desire for warm drinks persist, this indicates deficiency of Spleen and Stomach qi; Ren Shen Bai Zhu San (Ginseng and Atractylodes Macrocephala Powder) should be used. For dry feces stuck in the rectum unable to pass, pig bile suppository method is appropriate; avoid using purgative agents, lest they further damage Stomach qi, causing un-erupted lesions to fail to emerge and erupted lesions to fail to crust over. Generally, to distinguish between excess and deficiency, one should verify by observing the temperature of the hands and feet, or by asking about the desire to drink water or warm fluids.
One child presented with constipation, red and painful lesions, fever, thirst, and hot extremities. This was residual toxin acting internally. After one dose of Qianhu Zhike San, the bowels moved freely, and all symptoms subsided immediately. Subsequently, Liuwei Huoxue San (Six-Ingredient Blood-Invigorating Powder) was administered, leading to recovery.
Another child presented with fever and thirst due to smallpox, red and swollen painful lesions, and constipation. This indicated internal heat toxin. Initially, Qingliang Yin (Cooling Drink) was given for one dose, slightly reducing symptoms. Then, Niuzibang Tang (Burdock Decoction) was given for one dose, completely resolving symptoms. Next, Zicao Kuiban Tang (Arnebia Rapid-Eruption Decoction) was used to promote suppuration, followed by Xiaodu Yin (Toxin-Resolving Decoction) to facilitate crusting.
Another child presented with red lesions, manic panting, and difficult defecation. This indicated heat in the Stomach meridian. My father treated him with Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) combined with Celery Juice, resulting in recovery.
Sishun Qingliang Yin (Four-Harmony Cooling Drink): Treats accumulated heat causing facial redness, thirst, limb convulsions/tremors, and constipation.
Ingredients: Chi Shaoyao (Red Peony Root), Danggui (Angelica Sinensis), Gancao (Licorice Root), Dahuang (Rhubarb Root and Rhizome) (equal parts).
Usage: Take one qian per dose, decoct in water.
Note: Qingliang Yin is a bitter-sweet formula that drains internal heat. It is suitable when heat toxin is internal, causing constipation, without external symptoms. Lianqiao Yin (Forsythia Decoction) is a bitter-cold formula that releases the exterior and drains internally. It is suitable for excess heat in both interior and exterior, accompanied by irritability, thirst for cold drinks, constipation, and scanty dark urine. Do not overdose. Reckless sweating may lead to ulceration, while reckless purging may lead to collapse.
Xiaodu Yin: Jingjie (Schizonepeta Spike), Fangfeng (Saposhnikovia Root), Niuzibang (Burdock Fruit) (each 1.5 qian), Gancao (Licorice Root) (1 qian).
Usage: Decoct in water, take according to condition.
