Xu Zhongguang stated: In a case where pox scabs had not fully fallen off and the whole body was yellow and swollen, accompanied by high fever, abdominal distension, and red lips, this indicated that the spleen and stomach originally harbored damp-heat, compounded by residual toxins not yet cleared. The appropriate treatment is to eliminate accumulations, promote diuresis to drain dampness, and detoxify, using Wu Bu San (Five Tonics Powder) added with Coicis Semen (Yiyiren, 薏苡仁), Forsythiae Fructus (Lianqiao, 连翘), Gardeniae Fructus (Shanzhi, 山栀), Bambusae Folium (Zhuye, 竹叶), Saposhnikoviae Radix (Fangfeng, 防风), Atractodis Rhizoma Bai (Baizhu, 白术), Atractodis Rhizoma Cang (Cangzhu, 苍术), Magnoliae Officinalis Cortex (Houpo, 浓朴), and Poria (Fuling, 茯苓).
In another case of post-pox edema, the skin was thin and shiny, leaving an indentation upon pressure, accompanied by cough, thirst, and dysuria. This resulted from dietary injury to the spleen after the pox; spleen deficiency failed to control water metabolism, causing water to flood and act recklessly, soaking into the spleen earth and penetrating the skin, thus causing swelling. The wheezing and coughing occurred because rampant water failed to control heart fire, leading to excessive fire insulting lung metal (Fire overacts on Metal in Five Elements theory). It is also said: Water qi ascending to invade the lungs is the most difficult to treat. The dysuria arises because lung metal is controlled by fire, losing its descending function and failing to distribute and transform fluids. Treatment should employ herbs that tonify the middle, dry dampness, clear heat, and promote urination, such as Shi Pi Yin (Realize the Spleen Decoction), Wu Pi San (Five Spleens Powder), and Shi Qian San, to treat the condition.
In a case of generalized red swelling after pox due to residual toxins attacking, one should use Man Tian Xing Cao (Stellariae Herba or similar local herb used here), Shui Yang Gen (Salicis Root), Lonicerae Japonicae Flos (Jinyinhua, 银花), and Iris Tectorii Rhizoma (Malingtou, 马蔺头), crush each separately to extract juice, mix evenly, and administer orally. The leaves of Man Tian Xing resemble Coriandri Fructus (Yansui, 芫荽) and grow abundantly in shady, damp places under walls.
In another case of post-pox difficulty in urination and swelling below the waist, this was due to spleen and stomach qi deficiency failing to control kidney water, causing water to overflow into the lower jiao. One should promote urination using Wu Ling San (Five Ingredient Powder with Poria), administered intermittently with Mu Li San (Oyster Shell Powder), or Liu Jun Zi Tang (Six Gentlemen Decoction) added with Alismatis Rhizoma (Zexie, 泽泻).
In a case of generalized red swelling after pox manifesting as Chi You Feng (Red Roaming Wind, a type of acute cellulitis), this was caused by residual toxins not fully resolved, combined with indulgence in fried, roasted, and pungent-hot foods, steaming the intestines and stomach, where heat contended with blood. The appropriate formula is Xi Jiao Jie Du Tang (Rhinoceros Horn Detoxification Decoction).
In a case of red swelling of the cheeks and face after pox, termed Dun Du Feng (Escaping Toxin Wind), this resulted from exogenous wind pathogens accumulating in the skin and flowing into channels to form stubborn, red nodules. Internal treatment uses Jie Du Tang (Detoxification Decoction), and external application uses Yu Long San (Jade Dragon Powder).
In a summer pox case where the eruption filled with pus and scabbed, but urine was red, short, and scanty, with red, swollen, and transparent scrotum and external genitalia, this indicated severe bladder heat with toxic vapors flowing into the small intestine. It was treated with Ba Zheng San (Eight Corrective Ingredients Powder) and Hua Du Tang (Transform Toxin Decoction).
Wan Mizhai treated a man in his twenties whose pox was very dense. During the eruptive stage, swelling was abnormal, making the face look like a tin cake, a frightening appearance. However, his appetite was normal, bowel movements and urination were regular, and he slept quietly. Someone suggested using Mu Xiang San (Costus Root Powder). Wan Mizhai said: "Since there are no complicating diseases with the pox, medication is unnecessary. The pale complexion indicates that too many pox have erupted, depleting qi and blood so they cannot circulate fully; after a few days, it will naturally scab." This proved correct.
In another case of a child with very dense pox that did not erupt well, with a face like a tin cake, poor appetite, and thirst, someone suggested Mu Xiang San. Wan Mizhai said: "The child has no symptoms of vomiting, diarrhea, or interior deficiency, so it must not be used." Instead, he used Bao Yuan Tang (Protect the Origin Decoction) added with Dang Gui (Angelicae Sinensis Radix), Chi Shao (Paeoniae Radix Rubra), Fang Feng (Saposhnikoviae Radix), Jie Geng (Platycodonis Radix), and Niuxiangzi (Arctii Fructus), regulating the patient until recovery.
A woman aged twenty-four or twenty-five had very dense and severely swollen pox, with no intact skin on her body. After seven or eight days, pustules formed at the glabella and lips. Someone claimed this was the proper time for suppuration. Wan Mizhai said: "Not yet. The facial sores are red, indicating that the blood has not yet transformed into pus. If it suppurates abruptly, this is a malignant sign, and she will likely die from ulceration later." This indeed came true.
The son of Grand Administrator Tang, aged twelve, developed red swelling on the right shoulder after the pox scabbed. This was not due to toxin. Someone pricked it with a needle, after which the arm became unable to lift. Examination showed no pain, only weakness and inability to lift voluntarily, requiring support from the left hand. This indicated heat in the blood and deficiency of qi. Since the liver governs the sinews and nourishes them with blood, cold causes contraction and heat causes swelling, only by tonifying qi and nourishing blood can it heal. He prescribed a powder of Ren Shen (Ginseng Radix), [missing character, likely Huang Qi], Bai Zhu (Atractodis Rhizoma Bai), Gan Cao (Licorice Root), Chuan Xiong (Chuanxiong Rhizome), Dang Gui (Angelicae Sinensis Radix), Chuan Duan (Dipsaci Radix), Mu Xiang (Aucklandiae Radix), Jie Geng (Platycodonis Radix), Yi Yi Ren (Coicis Semen), and Fang Feng (Saposhnikoviae Radix), made into pills with yam paste, taken for half a month until cured.
Another child, after bathing following pox, developed swelling of the face, eyes, and whole body, indicating water qi retention. Si Jun Zi Tang (Four Gentlemen Decoction) was used to tonify the spleen and remove dampness, added with [missing character, likely Huang Qi] to secure the exterior, Fang Feng (Saposhnikoviae Radix) to overcome surface dampness, and Ma Huang (Ephedrae Herba) to expel water between the spleen layers. After one dose, the swelling reduced by half. Subsequently, Qian Shi Yi Gong San (Master Qian's Extra Efficacy Powder) added with Zhu Ling (Polyporus) and Zexie (Alismatis Rhizoma) brought about recovery.
