《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。
一小儿痘将愈，咳嗽面色黄白，嗽甚则赤，用五味异功散，调补而愈。

《痘疹方》记载：痘疮在尚未发出之前出现咳嗽，使用升麻汤。头痛、身体发热、恶寒并伴有咳嗽，使用参苏饮。呕吐痰涎，使用白术汤。时气病引起的头痛咳嗽，或者痘疮结痂后余毒未清导致的咳嗽，使用惺惺散。痘疮不起发（无法透发），使用升麻汤。感受寒邪导致头痛，胸闷烦乱且咳嗽，使用木香散。发热且咳嗽严重，没有其他症状，使用生地黄散。风热引起的咳嗽，使用五味子汤。咽喉不利（通畅度差），使用甘桔防风汤。
我认为上述前症在痘疮未出或欲出之际，是由于热毒上熏清道（呼吸道及头面部清窍），导致肺气不宁，适宜使用惺惺散。如果痘疮已经发出之后，则属于元气虚弱，不能固护腠理（皮肤毛孔及肌表防御系统），风邪乘虚侵袭，适宜使用五味异功散加桔梗、五味子，以补益脾肺。
有一个男子咳嗽、打喷嚏，腮颊颜色赤白相间，眼睑皆红，全身皮肤发红，我认为是心脏型的痘疹，他疑惑而未用药，十余天后痘疹全部红活起发。我认为既然痘疹红活起发，就不必再服药。到了第十七天，大便下血，脓疮结痂而痊愈。
有一个小儿痘色红壮热，咳嗽痰多，烦热口渴，用人参清膈散一剂，各种症状顿时消退，每日饮用芹菜汁，十余天后结痂。
有一个小儿痘疮逐渐痊愈，但仍有咳嗽，肺脉大而无力，使用参苏饮，咳嗽逐渐好转。因为母亲饮酒，咳嗽又复发，使用五味异功散加桑白皮、杏仁、山栀，母子同服而痊愈。
有一个小儿患痘疮，第十二天出现咳嗽吐痰，胸中隐痛，肺脉数滑。我说：这是兼患肺痈（肺部化脓性病变），应当使用桔梗汤。患者不信，第二天果然吐出脓血，使用桔梗汤而痊愈。
有一个十四岁的小儿，痘疮痊愈后咳嗽，脉数而无力，早晨服用补中益气汤，晚上服用六味丸料，各服数剂后逐渐好转。结婚后，再次出现咳嗽发热，仍用前药及八珍汤等药物而痊愈。
有一个小儿痘疮将愈，咳嗽面色黄白，咳嗽剧烈时面色变红，使用五味异功散，调理补益而痊愈。

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).
