大病后。从腰以下有水气。牡蛎泽泻散主之。（水气）
此脾胃气虚。土不能摄水。故溢下焦。腰以下为肿也。
腰以上肿者。当发汗。腰以下肿者。宜利小便。
大病瘥后。喜唾。久不了了。胃上有寒。当以丸药温之。宜理中丸。（喜唾）
邵评∶唾。涎沫也。中土阳虚。不能收摄津液。而冷涎上泛也。宜理中丸加益智仁温纳之。
胃中虚寒。则津液不能收摄。故喜唾。宜温胃。
伤寒解后。虚羸少气。气逆欲吐者。竹叶石膏汤主之。（欲吐）
此津液不足。故虚羸少气。虚火上炎。故气逆欲吐。宜养肺胃之阴。则津液复。诸
症自除矣。
邵评∶肺胃津亏气馁。余热挟胃火上升。竹叶石膏汤。却是正法。惟竹叶宜易竹茹。
病患脉已解。而日暮微烦。以病新瘥。人强与谷。脾胃气尚弱。不能消谷。故令人微
烦。损谷则愈。（日暮微烦）
阳明旺于申酉戌。宿食在胃。故日暮微烦。当小下之。以损宿谷。枳实栀子豉汤主之。
大病瘥后。劳复者。枳实栀子豉汤主之。若有宿食者。加大黄如博棋子大五六枚。
此劳复。因病后气虚。邪气又结于上焦。其症不一。故不着其病形。惟散其上焦之邪足矣。（劳复）
邵评∶正虚而复受外邪。病之变见不一。故不定症形。当随症治之。
有宿食加大黄。此指劳复之有宿食在肠胃者。故可下。非治食复也。若宿食在
胃脘。当消导。在上脘。吐之亦可。
After a major illness, fluid accumulation occurs below the waist. Muli Zexie San (Oyster Shell and Alisma Powder) is the primary prescription. (Fluid accumulation)
This is due to deficiency of Spleen and Stomach Qi, where Earth fails to control Water, causing overflow into the Lower Jiao, resulting in edema below the waist.
For edema above the waist, sweating method should be used; for edema below the waist, promoting urination is appropriate.
After recovery from a major illness, if the patient frequently spits saliva without cessation for a long time, it indicates Cold in the Stomach. Pill medicine should be used to warm the interior; Lizhong Wan (Regulate the Middle Pill) is suitable. (Frequent spitting)
Shao's Commentary: Saliva refers to phlegm-saliva. Yang deficiency in the Middle Jiao fails to secure body fluids, leading to the reflux of cold saliva. It is advisable to add Yizhi Ren (Alpinia Oxyphylla Fruit) to Lizhong Wan to warm and grasp Qi.
Deficiency-Cold in the Stomach prevents the retention of body fluids, hence the tendency to spit. Warming the Stomach is indicated.
After the resolution of Shanghan (Cold Damage), if the patient presents with emaciation, shortness of breath, and rebellious Qi with a desire to vomit, Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) is the primary prescription. (Desire to vomit)
This is due to insufficiency of body fluids, causing emaciation and shortness of breath; Deficient Fire flaming upward causes rebellious Qi and desire to vomit. Nourishing the Yin of the Lung and Stomach will restore body fluids, and symptoms will resolve spontaneously.
Shao's Commentary: With deficiency of Lung and Stomach fluids and Qi, residual heat combined with Stomach Fire rises. Zhuye Shigao Tang is the correct method. However, Zhuye (Bamboo Leaf) should be replaced with Zhuru (Bamboo Shavings).
If the patient's pulse has normalized but they experience slight irritability at dusk, it is because the illness has just resolved, and people force-feed them. The Spleen and Stomach Qi are still weak and cannot digest food, causing slight irritability. Reducing food intake will lead to recovery. (Slight irritability at dusk)
The Yangming channel is vigorous during Shen, You, and Xu hours. Retained food in the Stomach causes slight irritability at dusk. A mild purgative action is needed to eliminate retained food; Zhishi Zhizi Chi Tang (Immature Bitter Orange, Gardenia, and Fermented Soybean Decoction) is the primary prescription.
For relapse due to overexertion after a major illness, Zhishi Zhizi Chi Tang is the primary prescription. If there is retained food, add Dahuang (Rhubarb Root) in pieces the size of chess cubes, five or six pieces.
This is relapse due to labor. Due to post-illness Qi deficiency, pathogenic factors re-accumulate in the Upper Jiao. Symptoms vary, so specific disease forms are not detailed; dispersing pathogenic factors in the Upper Jiao is sufficient. (Relapse due to labor)
Shao's Commentary: When Zheng Qi (Upright Qi) is deficient and external pathogens are contracted again, disease manifestations vary, so symptom patterns are not fixed. Treatment should follow the symptoms.
Adding Dahuang applies to cases of relapse due to labor with retained food in the intestines and stomach, allowing for purgation. This does not refer to treating relapse due to diet. If retained food is in the epigastrium, resolving methods should be used; if in the upper epigastrium, inducing vomiting is also an option.
