万密斋治李氏女痘，脓成将靥，忽腹胀且痛，气喘呻吟。曰∶疮既胖壮，脓又饱满，其脉弦滑，此非痘毒，
乃伤食也。询之，因食鸡肉、糯米饭。曰∶宜急下之。或谓痘疮首尾不可下，恐虚其里，不靥也。曰∶病不执
方，药贵对症，有是病则有是药，下之无妨。遂以原物作汤，吞丁香脾积丸，得利而安。

Wan Mizhai treated a girl of the Li family suffering from smallpox. When the pustules had formed and were about to crust, she suddenly experienced abdominal distension and pain, shortness of breath, and groaning. He said: "The pustules are plump and robust, and the pus is abundant; her pulse is wiry and slippery. This is not smallpox toxin, but food stagnation." Upon inquiry, it was found that she had eaten chicken meat and glutinous rice. He said: "Urgent purgation is required." Some argued: "Purgation should not be used at any stage of smallpox, for fear of weakening the interior and preventing crusting." He replied: "Treatment does not adhere to fixed formulas; medicine must suit the condition. If there is this disease, use this medicine; purgation is harmless." Thus, he decocted the original food items into a soup and administered Dingxiang Piji Wan (Dingxiang Spleen Accumulation Pill) orally. After defecation, the patient stabilized.
The son of the Jin family, when his smallpox pustules were forming pus, suddenly developed abdominal distension and pain, shortness of breath, and irritability. His pustules were bright, plump, and full, indicating it was not toxin-related but definitely caused by food stagnation. Indeed, he had overeaten wheat-based foods. The same method was used; after defecation, the condition slightly stabilized. Then, Yigong San (Modified Yi Gong Powder) from Qian's formula, augmented with Qingpi (Qingpi, 青皮) and Shanzha (Shanzha, 山楂), was administered. One dose resulted in recovery.
Fei Jianzhong treated the son of Yan Xiaolian, aged six. In mid-summer of the Bingxu year, smallpox appeared. The lesions were dry, red, and rough, with depressed tops that did not relax. The body heat was like burning iron, accompanied by restlessness and agitation. Palpation of the abdomen and diaphragm revealed tenderness and distress, and belching emitted a putrid odor. This indicated internal retention of toxic fire and stagnation in the middle jiao (middle burner). Da Huang (Rhubarb Root and Rhizome) 2 qian, Qingpi (Green Citrus Peel) approximately 1 qian, Chantui (Cicada Slough), Jingjie (Schizonepeta Spike), Chi Shao (Red Peony Root), Hong Hua (Safflower), and Dideng (Viola Herba) were used. Shan Zha (Hawthorn Fruit) 1 liang was decocted to replace water. Two doses were taken consecutively, resulting in the passage of much retained matter. The smallpox lesions instantly rose, and their color turned red. Coptis Rhizome (Huanglian) and Rehmannia Root (Shengdi) were added to the previous prescription. Gradually, the lesions whitened and filled with pus. However, the heat had not yet harmonized. The previous prescription continued until the twelfth day before success was achieved.
Fei Jianzhong’s own son, aged two, presented with smallpox in early summer. He suffered from high fever and coma. The lesions were dry, red, and dense, but distinct as individual pearls, without collapsing. By the third day, there was no sign of eruption. Breathing was coarse, and he felt irritable and stifled, passing flatus that was extremely foul-smelling. This was due to having eaten one Zhutu Yuanzi (a dumpling made from Chinese Ramie Root) weighing one liang prior to the onset of smallpox. Zhi Shi (Immature Bitter Orange), Shanzha (Hawthorn Fruit), Jiegeng (Platycodon Root), Qianhu (Peucedani Radix), Guangpi (Tangerine Peel), Maiya (Barley Sprout), Chi Shao (Red Peony Root), Chantui (Cicada Slough), and Niubang (Arctium Fruit) were used. Much impacted stool was expelled, and the lesions immediately erupted with a reddish and moist appearance. Although they remained very dense later, recovery was eventually achieved.
A boy of the Shi family presented with smallpox. Initially, the eruption was vigorous, but by the fourth day, it failed to rise further. He became manic, irritable, and screamed until hoarse, with his eyes rolling upward intermittently. Inspection showed the roots of the lesions were still present, but they were dense, resembling alum-red, with depressed and dry tops. The body temperature was actually cool. Palpation of the chest, diaphragm, and extremities revealed swelling. Pulse diagnosis of the right hand Cun and Guan positions showed a surging, slippery, and excess quality. This indicated severe internal accumulation and blockage. Zhi Shi (Immature Bitter Orange) 5 qian, Qingpi (Green Citrus Peel) and Qianhu (Peucedani Radix) each 3 qian, Jiegeng (Platycodon Root) 0.5 fen, assisted by Jingjie (Schizonepeta Spike) and Chantui (Cicada Slough), were prescribed. Shan Zha (Hawthorn Fruit) 2 liang was decocted to replace water. Two heads' juice (pig bile and cattle bile) was administered overnight. At noon the next day, another dose was given. In the afternoon, much retained filth was passed, including undigested chicken meat. Late in the evening, another bowel movement occurred, and the lesions instantly erupted. The spirit calmed, body temperature rose significantly, though the color had not yet changed. This was because the blockage was cleared, allowing the fire-toxin to manifest externally. The treatment was changed to cooling the blood and clearing resolution. The color gradually became vibrant red, the pus became plentiful, and recovery was achieved.
