陈文秀先生云∶痘疮泻水谷，或白色、或淡黄者，宜服十一味木香散，送肉豆蔻丸。若泻多津液内耗，血气不荣，
其疮虽起发，亦不能结靥。如身温腹胀，切牙喘渴者难治，缘津液枯耗，而饮水不止，荡散真气，故多死也，速与十一
味木香散救之，如不愈，急用十二味异功散。窃谓豆蔻丸治阳气虚寒滑泻之涩剂。盖肾主大便，若因肾气不固而致前症
者，宜用十一味木香散，或六君子汤送四神丸。若欲泻不泻，脾气虚而下陷也，用补中益气汤加肉豆蔻。饮食不化，手
足并冷，脾气虚寒也，用四君子汤加附子。
一小儿出痘泄泻，腹胀烦渴，饮沸汤而不知热，先君谓阳气虚寒，用十一味木香散二剂，泄泻顿止，饮汤嫌热，此
阳气复也，乃用六君、干姜、木香、归、 而靥。
一小儿痘疮愈后泄泻，饮食不化，此脾肾气虚，用六君、补骨脂、肉豆蔻，泻止，用参 四圣散，接补元气而痊。
一小儿发热饮冷，唇舌皱烈，泻粪秽臭。先君以为内蕴，用前胡枳壳散一剂稍愈；又用竹叶石膏汤加漏芦，乳母
服之，其儿顿安。
一小儿痘后作泻久不愈，而肌体骨立，此脾肾虚弱也，用二神丸、五味异功散渐愈，因停食吞酸作泻，肚腹重坠，
此脾气下陷也，先用补中益气汤为主，佐以五味异功散渐愈；又用参 四圣散、托里散，治其疮而痊。
一小儿出痘，发热燥渴，色黯出血，足热腰痛，此脾肾虚热，用圣济犀角地黄汤一剂，却用地黄丸料数剂而贯，又
用参 内托散而痊。
一小儿痘疮将愈，侵晨泄泻，饮食不化，余以为肾泻，朝用补中益气汤，夕用二神丸而愈。

陈文秀先生说：痘疮患者出现水样便夹杂未消化食物，或者大便呈白色、淡黄色的症状，适宜服用十一味木香散，并用肉豆蔻丸送服。如果腹泻严重导致体内津液耗损，气血无法濡养肌肤，那么即使痘疹已经发出，也无法结痂愈合。如果身体温暖但腹部胀满，伴有咬牙、气喘和口渴的症状，则属于难治之症，这是因为津液枯竭耗损，虽然不断饮水却仍感口渴，导致真气涣散，所以大多会导致死亡，应迅速给予十一味木香散进行救治；如果病情没有好转，紧急使用十二味异功散。我认为肉豆蔻丸是治疗阳气虚寒所致滑脱性腹泻的收敛固涩剂。因为肾主管大便，如果是因肾气不固而导致上述症状的，适宜使用十一味木香散，或者用六君子汤送服四神丸。如果出现想排便却排不出来的情况，这是脾气虚弱且下陷的表现，应使用补中益气汤加入肉豆蔻。如果饮食不能消化，手脚同时发冷，这是脾气虚寒的表现，应使用四君子汤加入附子。
有一个小孩出痘疮期间发生泄泻，腹部胀满，烦躁口渴，喝滚烫的水却不知道烫（感觉不到热），我的父亲认为这是阳气虚寒，使用了二剂十一味木香散，泄泻立刻停止，此时孩子喝汤嫌热，这说明阳气已经恢复，于是使用六君子汤、干姜、木香、当归等药物，促使痘疮结痂愈合。
另一个小孩在痘疮痊愈后仍然泄泻，饮食无法消化，这是脾肾气虚的表现，使用了六君子汤、补骨脂、肉豆蔻，腹泻停止后，使用参苓四圣散，接续补益元气而痊愈。
还有一个小孩发热并喜欢喝冷饮，嘴唇和舌头干燥起皱，排泄物秽浊恶臭。我的父亲认为是体内蕴积热毒，使用前胡枳壳散一剂后稍有好转；接着使用竹叶石膏汤加入漏芦，让乳母服用，那个孩子顿时安宁。
还有一个小孩在出痘后腹泻长久不愈，导致身体消瘦如柴，这是脾肾虚弱的表现，使用二神丸、五味异功散逐渐痊愈；后来因为停食（消化不良）吞酸导致腹泻，肚腹有沉重下坠感，这是脾气下陷的表现，先用补中益气汤为主，辅以五味异功散逐渐痊愈；又使用参苓四圣散、托里散，治疗其疮疡而痊愈。
还有一个小孩出痘，发热燥渴，痘色暗紫出血，脚热腰痛，这是脾肾虚热的表现，使用圣济犀角地黄汤一剂，随后用地黄丸药料数剂来巩固疗效，又使用参芪内托散而痊愈。
还有一个小孩痘疮即将痊愈时，清晨发生泄泻，饮食无法消化，我认为是肾泻，早晨服用补中益气汤，晚上服用二神丸而痊愈。

Mr. Chen Wenxiu stated: In cases of smallpox accompanied by diarrhea of watery stool mixed with undigested food, or where the stool is white or pale yellow, it is appropriate to administer Shiyiwei Muxiang San (Eleven-Ingredient Costus Root Powder) and take it with Roudoukou Wan (Nutmeg Pill). If severe diarrhea leads to internal depletion of body fluids and Qi and Blood failing to nourish the skin, even if the pustules have erupted, they will not form scabs. If the body is warm but the abdomen is distended, accompanied by teeth grinding, panting, and thirst, this is difficult to treat. This is because body fluids are exhausted; despite continuous drinking, thirst persists, scattering the True Qi, so death often ensues. One should quickly administer Shiyiwei Muxiang San to rescue the patient; if there is no improvement, urgently use Shi'erwei Yigong San (Twelve-Ingredient Yi Gong Powder). I consider Roudoukou Wan to be an astringent formula treating slippery diarrhea due to deficiency-cold of Yang Qi. Since the Kidney governs defecation, if the aforementioned symptoms are caused by insecurity of Kidney Qi, one should use Shiyiwei Muxiang San, or administer Six-Ingredient Gentlemen's Decoction (Liujunzi Tang) to send down Sishen Wan (Four Spirits Pill). If there is a sensation of needing to defecate but being unable to do so, this indicates deficiency and sinking of Spleen Qi; one should use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) added with Nutmeg. If food is not digested and both hands and feet are cold, this indicates deficiency-cold of Spleen Qi; one should use Four-Ingredient Gentlemen's Decoction (Sijunzi Tang) added with Aconite Root (Fuzi).
A child suffering from smallpox developed diarrhea, abdominal distension, irritability, and thirst, drinking boiling water without feeling the heat. My father considered this to be deficiency-cold of Yang Qi and prescribed two doses of Shiyiwei Muxiang San, which immediately stopped the diarrhea. The child then found the soup too hot, indicating the recovery of Yang Qi. Subsequently, Liujunzi Tang, Dried Ginger (Ganjiang), Aromatic Costus Root (Muxiang), and Angelica Sinensis (Danggui) were used to facilitate scabbing.
Another child suffered from diarrhea after the resolution of smallpox, with inability to digest food. This was attributed to deficiency of Spleen and Kidney Qi. Liu Jun Zi Tang, Psoralea Fruit (Buguzhi), and Nutmeg were administered; once the diarrhea ceased, Shen Ling Sibai San (Ginseng and Poria Powder for the Four Sages) was used to replenish Yuan Qi, leading to recovery.
Another child presented with fever, preference for cold drinks, wrinkled and dry lips and tongue, and foul-smelling feces. My father diagnosed internal accumulation of heat and prescribed Qianhu Zhike San (Peucedanum and Aurantium Powder) for one dose, resulting in slight improvement. Then, Zhu Ye Shi Gao Tang (Bamboo Leaf and Gypsum Decoction) added with Rhapontic Rhizome (Loulu) was given to the nursing mother, bringing immediate relief to the infant.
Another child had prolonged diarrhea following smallpox, resulting in emaciation. This was diagnosed as weakness of the Spleen and Kidney. Ershen Wan (Two Spirits Pill) and Wuwei Yigong San (Five-Ingredient Yi Gong Powder) were used gradually to achieve improvement. Later, due to food stagnation causing acid regurgitation and diarrhea, along with a heavy bearing-down sensation in the abdomen, this was identified as sinking of Spleen Qi. Buzhong Yiqi Tang was used as the primary treatment, assisted by Wuwei Yigong San, leading to gradual recovery. Finally, Shen Ling Sibai San and Tuoli San (Support the Interior Powder) were used to treat the sores, resulting in full recovery.
Another child with smallpox exhibited fever, dryness, and thirst, dark-colored eruptions with bleeding, hot feet, and lower back pain. This was diagnosed as deficiency-heat of the Spleen and Kidney. Shengji Xijiao Dihuang Tang (Shengji Rhinoceros Horn and Rehmannia Decoction) was administered for one dose, followed by several doses of Dihuang Wan material to consolidate the effect, and finally, Shenqi Neituo San (Ginseng and Astragalus Internal Support Powder) was used for recovery.
Another child experienced morning diarrhea just as the smallpox was healing, with undigested food in the stool. I diagnosed this as Kidney Diarrhea. Bu Zhong Yi Qi Tang was administered in the morning, and Ershen Wan in the evening, leading to recovery.
