《痘疹方》云∶痘疮未出之先咳嗽，升麻汤。头疼身热，恶寒咳嗽，参苏饮。呕吐痰涎，白术汤。时气头疼咳嗽，
或靥后余毒咳嗽，惺惺散。疮不起发，升麻汤。感寒头痛，闷乱咳嗽，木香散。发热嗽甚，别无他症，生地黄散。风热
咳嗽，五味子汤。咽喉不利，甘桔防风汤。窃谓前症未出欲出之际，乃热毒上熏清道，肺气不宁，宜用惺惺散。若已出
之后，则属元气虚弱，不能固卫腠理，风邪乘虚而袭，宜用五味异功散加桔梗、五味子，以补脾肺。
一男子咳嗽嚏喷，腮颊赤白，胞皆赤，遍身赤 ，余谓此心脏痘疹，彼疑惑而未用药，旬余皆红活起发。余谓既红
活起发，不必服药。至十七日，大便下血，脓疮痂而痊。
一小儿痘赤壮热，咳嗽痰甚，烦热作渴，用人参清膈散一剂，诸症顿退，日用芹菜汁，旬余而靥。
一小儿痘渐愈，咳嗽，肺脉大而无力，用参苏饮，咳嗽渐愈。因母饮酒，又复咳，用五味异功散加桑白皮、杏仁、
山栀，母子并服而愈。
一小儿痘疮，十二日患咳嗽唾痰，胸中隐痛，肺脉数滑。余曰∶此兼患肺痈也，当用桔梗汤。不信，翌日果吐脓血，
用桔梗汤而愈。
一小儿十四岁，痘愈后，咳嗽，脉数而无力，朝用补中益气汤，夕用六味丸料，各数剂渐愈。毕姻后，咳嗽发热，
仍用前药及八珍等药而痊。

According to the *Douzhen Fang* (Formulas for Smallpox and Measles): For coughing before the eruption of smallpox/measles, use Shengma Tang (Cimicifugae Decoction). For headache, fever, aversion to cold, and coughing, use Shen Su Yin (Ginseng and Perilla Leaf Infusion). For vomiting of phlegm and saliva, use Baizhu Tang (Atractylodis Macrocephalae Decoction). For headache and coughing caused by seasonal pathogens, or residual toxicity causing coughing after the scabbing phase, use Xingxing San (Xingxing Powder). For failure of lesions to erupt, use Shengma Tang. For headache due to cold invasion, chest oppression, restlessness, and coughing, use Muxiang San (Costus Root Powder). For severe coughing with fever but no other symptoms, use Shengdihuang San (Rehmanniae Radix Powder). For coughing due to wind-heat, use Wuweizi Tang (Schisandrae Fructus Decoction). For throat discomfort, use Ganjie Fangfeng Tang (Licorice, Platycodon, and Saposhnikovia Decoction).
I believe that during the pre-eruptive or eruptive stage, these symptoms are caused by heat-toxin steaming upwards into the clear passages, disturbing Lung Qi. In such cases, Xingxing San is appropriate. After the lesions have erupted, however, the condition belongs to deficiency of Yuan Qi (Original Qi), which fails to secure the Couli (skin pores and interstitial spaces), allowing Wind pathogen to invade via the deficiency. In this case, Wuyi Gong San (Five-Agent Tonic Decoction) added with Jiegeng (Platycodon Root) and Wuweizi (Schisandra Fruit) should be used to tonify the Spleen and Lung.
A male patient presented with coughing, sneezing, red and white cheeks, red eyelids, and generalized erythema. I diagnosed this as a Heart-type rash. He was skeptical and did not take medicine; after more than ten days, the lesions became bright red and erupted successfully. I stated that since the lesions were bright red and erupting, no further medication was necessary. On the seventeenth day, he passed blood in his stool, and the pustules crusted over, leading to recovery.
A pediatric patient presented with bright red smallpox, high fever, severe coughing with phlegm, irritability, fever, and thirst. One dose of Renshen Qingge San (Ginseng Clear Diaphragm Powder) caused all symptoms to recede immediately. Daily consumption of celery juice led to scabbing within ten days.
A pediatric patient whose smallpox was gradually resolving still had a cough. The Lung pulse was large but forceless. Shen Su Yin was administered, and the cough gradually improved. Because the mother consumed alcohol, the cough recurred. Wuyi Gong San (Five-Agent Tonic Decoction) was modified with Sangbaipi (Morus Cortex), Xingren (Apricot Seed), and Zhizi (Gardenia Fruit). Both mother and child took the medicine and recovered.
A pediatric patient with smallpox developed coughing and expectoration on the twelfth day, accompanied by dull chest pain. The Lung pulse was rapid and slippery. I stated: "This is complicated by Fei Yong (Lung Abscess); Jiegeng Tang (Platycodon Decoction) should be used." The patient did not believe this. The next day, he indeed expectorated pus and blood. Treatment with Jiegeng Tang resulted in recovery.
A fourteen-year-old boy had coughing after smallpox resolution. The pulse was rapid but forceless. He took Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) in the morning and Liuwei Wan (Six-Ingredient Pill with Rehmannia) ingredients in the evening. After several doses, he gradually improved. After marriage, he experienced recurrent coughing and fever. He was treated again with the previous formulas and Bazhen Tang (Eight-Treasure Decoction), leading to recovery.
A pediatric patient nearing recovery from smallpox had coughing and a sallow-white complexion. His face turned red when coughing severely. Wuyi Gong San (Five-Agent Tonic Decoction) was used for regulation and tonification, resulting in recovery.

If phlegm obstructs upwards, assist with Baolong Wan (Embrace Dragon Pill).
