张洁古先生云∶痘疹未有不因潮热而出者。观其热之时，知自何脏发出，寅卯辰时属肝，出水泡；巳午未时属心，
出疮；申酉戌时属肺，为脓泡；亥子丑时属脾，出疹子。惟肾独居腑下，不受秽浊，故无症耳。窃谓前症当察其虚实，
若壮热饮水，便秘，属实热也，少用清凉饮下之。发热饮冷，大便不秘，属虚热也，宜人参白术散补之。若下而发热愈
甚，此阴虚而阳无所附也，用四物、参、 之类补之。若下而潮热面赤者，血气发躁也，用当归补血汤补之。若见发搐
等症，乃肝虚而内生风也，用四物、天麻、钩藤钩补之。用发散之剂，而热愈甚，此表虚而外热也，用四君、当归、黄
补之。
一小儿先潮热，午前甚，面青痘赤，出而热不止，或时发搐，手足不热不冷，此阳明胃经症，为肝木所侮，先用补
中益气汤加钩藤钩，四剂而热止；痘色红活，乃去钩藤钩，又四剂而贯浆，又用八珍汤而痊。
一小儿痘红活，寅卯时潮热作渴，此肝经风热症，用柴胡栀子散末，三服热止浆贯，又用八珍汤、山栀、丹皮而靥。
一小儿靥后潮热，手足发冷，余谓胃气虚弱，用五味异功散，佐以补中益气汤而愈。因饮食过度，前症复作，更腹
胀，大便不实，小便重坠，此脾虚也，用补中益气汤而痊。
一小儿痘后，不时寒热噫气，饮食吞酸，服二陈、枳实、黄连，更寒热如疟，腹坠下气，此中气复伤而下陷也，
朝用补中益气汤，夕用五味异功散，各加干姜、木香而愈。
一儒者先潮热出痘，面青胁痛，此肝经之症，用四君、柴胡、当归、山栀，二剂胁痛稍缓，又佐以加味逍遥散而痛
止，却用托里散，浆贯而靥。后又潮热，用地黄丸而愈。
一妇人患此，误服寒凉之剂，烦躁作渴，饮沸汤而不知热，脉洪数，按之微细，此血气俱虚，用大剂十全大补汤加
姜、桂四剂，更恶寒切牙，此虚极而药力未能及也，于前药内，更加附子一片，二剂诸症顿退，乃去附子，又二剂将
安，去姜、桂常服而痊。
一小儿痘愈后，潮热，饮食少思，面色痿黄，久治不愈，热后面与手足如冰，余谓脾气虚寒，当用六君、姜、桂，
不信而死，手足皆黑。惜哉！

张洁古先生曾说：痘疹没有不是因潮热而发出来的。观察其发热的时间，可以知道是从哪一脏发出的：寅、卯、辰时属于肝，发出水泡；巳、午、未时属于心，发出疮疡；申、酉、戌时属于肺，形成脓泡；亥、子、丑时属于脾，发出疹子。只有肾单独居于下焦，不受秽浊之气影响，所以没有相应的症状表现。我认为上述病症应当辨别其虚实：如果高热且想喝水，大便秘结，属于实热证，应少量使用清凉饮攻下。如果发热且想喝冷饮，大便不秘结，属于虚热证，宜用人参白术散进行补益。如果攻下之后发热反而更严重，这是阴虚而阳气无所依附的表现，应用四物汤、人参等药物进行补益。如果攻下之后出现潮热且面色发红，这是血气躁动不安的表现，应用当归补血汤进行补益。如果出现抽搐等症状，这是肝虚而生内风的表现，应用四物汤、天麻、钩藤进行补益。如果使用发散解表的药剂后发热更加严重，这是表虚而外感邪热的表现，应用四君子汤、当归、黄芪进行补益。
有一个小儿先出现潮热，午前加重，面色青而痘色红，出痘后发热不止，有时发生抽搐，手足温度不冷也不热，这是阳明胃经的病症，被肝木所克制（侮），先用补中益气汤加钩藤，服用四剂后热止；痘色红润鲜活，于是去掉钩藤，又服四剂后痘浆充盈，再用八珍汤治疗而痊愈。
有一个小儿痘色红润鲜活，在寅、卯时出现潮热并感到口渴，这是肝经风热证，用柴胡栀子散的药末，服用三剂后热止浆充，再用八珍汤、山栀、丹皮治疗直到结痂。
有一个小儿在痘疹结痂后出现潮热，手足发冷，我认为这是胃气虚弱，用五味异功散，配合补中益气汤治疗而痊愈。因为饮食过量，之前的病症复发，并且出现腹胀，大便不成形，小便有重坠感，这是脾虚，用补中益气汤治疗而痊愈。
有一个小儿在痘疹之后，不时出现寒热交替和嗳气，饮食吞酸，服用二陈汤、枳实、黄连后，寒热像疟疾一样发作，腹部下坠感明显且有排气现象，这是中气再次受损而下陷，早晨服用补中益气汤，晚上服用五味异功散，各加入干姜、木香而痊愈。
有一位读书人先出现潮热然后出痘，面色青且胁肋疼痛，这是肝经的病症，用四君子汤、柴胡、当归、山栀，服用两剂后胁痛稍缓，又配合加味逍遥散治疗使疼痛停止，随后用托里散，待痘浆充盈并结痂。后来又出现潮热，用地黄丸治疗而痊愈。
有一位妇女患此病，误服了寒凉的药物，出现烦躁口渴，喝滚烫的水却感觉不到热，脉象洪数但按之微细，这是气血俱虚，用大剂量的十全大补汤加入生姜、肉桂，服用四剂后，又出现怕冷且咬牙的症状，这是极度虚弱导致药力未能及时到达，在前面的药方中，再加一片附子，服用两剂后所有症状顿时消退，于是去掉附子，又服两剂后逐渐安稳，去掉生姜、肉桂常服而痊愈。
有一个小儿痘疹痊愈后，出现潮热，饮食减少且食欲不振，面色萎黄，久治不愈，发热后面部和手足像冰一样冷，我认为这是脾气虚寒，应当用六君子汤、生姜、肉桂，患者不信从而死亡，手足都变黑。可惜啊！

Mr. Zhang Jiegu once said: There is no case of smallpox or measles that does not erupt due to tidal fever (tidal fever). By observing the time of fever, one can determine which organ it originates from: Yin, Mao, and Chen hours belong to the Liver, producing blisters; Si, Wu, and Wei hours belong to the Heart, producing sores; Shen, You, and Xu hours belong to the Lung, forming pustules; Hai, Zi, and Chou hours belong to the Spleen, producing maculopapular rashes. Only the Kidney resides alone in the lower jiao, unaffected by turbid pathogens, thus presenting no specific symptoms. I believe that for the aforementioned conditions, one must distinguish between deficiency and excess. If there is high fever with thirst and constipation, it is an excess-heat syndrome; a small amount of Qingliang Yin (Cooling Drink) should be used to purge. If there is fever with a desire for cold drinks but no constipation, it is a deficiency-heat syndrome; Renshen Baizhu San (Ginseng and Atractylodes Macrocephala Powder) should be used to tonify. If purging leads to intensified fever, this indicates yin deficiency with yang having no anchor; Siwu Tang (Four Substances Decoction) and Renshen (Ginseng) should be used to tonify. If tidal fever and facial flushing occur after purging, this indicates restlessness of blood and qi; Danggui Buxue Tang (Dong Quai Tonifying Blood Decoction) should be used to tonify. If convulsions and other symptoms appear, this indicates liver deficiency generating internal wind; Siwu Tang (Four Substances Decoction), Tianma (Gastrodia Rhizome), and Goutenggou (Uncaria Rhynchophylla) should be used to tonify. If dispersing agents cause increased fever, this indicates exterior deficiency with external heat; Sijunzi Tang (Four Gentlemen Decoction), Danggui (Angelica Sinensis), and Huangqi (Astragalus Root) should be used to tonify.
A child first presented with tidal fever, worsening before noon, with a cyanotic complexion and red lesions. After eruption, the fever persisted, accompanied by occasional convulsions and limbs that were neither hot nor cold. This is a syndrome of the Yangming Stomach meridian, suppressed by Liver wood. Initially, Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with Goutenggou was administered for four doses, stopping the fever. When the lesions became bright red and vibrant, Goutenggou was removed, and another four doses were given until the lesions filled with pus. Finally, Bazhen Tang (Eight Treasures Decoction) was used to achieve recovery.
Another child had bright red lesions and experienced tidal fever with thirst during Yin and Mao hours. This is a Liver meridian wind-heat syndrome. Chaihu Zhizi San (Bupleurum and Gardenia Powder) was administered as a powder; after three doses, the fever ceased and lesions filled with pus. Bazhen Tang (Eight Treasures Decoction), Zhizi (Gardenia Fruit), and Danpi (Moutan Cortex) were then used until scabbing occurred.
A child presented with tidal fever and cold extremities after scabbing. I diagnosed weak stomach qi and treated with Wuyi Yigong San (Five Agents Extraordinary Efficacy Powder), assisted by Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction), resulting in recovery. Due to overeating, previous symptoms recurred with abdominal distension, loose stools, and a heavy sensation in urination, indicating Spleen deficiency. Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) was used to achieve recovery.
A child presented with intermittent chills and fever, belching, and acid regurgitation after smallpox. After taking Erchen Tang (Two Aged Decoction), Zhishi (Immature Bitter Orange), and Huanglian (Coptis Rhizome), the chills and fever resembled malaria, with abdominal heaviness and excessive flatulence. This indicated further injury to middle qi with sinking. Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) was administered in the morning, and Wuyi Yigong San (Five Agents Extraordinary Efficacy Powder) in the evening, each supplemented with Ganjiang (Dried Ginger) and Muxiang (Aucklandiae Radix), leading to recovery.
A scholar first presented with tidal fever followed by smallpox eruption, cyanotic complexion, and hypochondriac pain. This is a Liver meridian syndrome. Sijunzi Tang (Four Gentlemen Decoction), Chaihu (Bupleurum Root), Danggui (Angelica Sinensis), and Zhizi (Gardenia Fruit) were used; after two doses, hypochondriac pain eased slightly. Jiawei Xiaoyao San (Modified Free and Easy Wanderer Powder) was added to stop the pain. Tuoli San (Support the Interior Powder) was then used until lesions filled with pus and scabbed. Later, tidal fever recurred and was cured by Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia).
A woman suffered from this condition and mistakenly took cold-natured medicines, resulting in irritability, thirst, and drinking boiling water without feeling heat. Her pulse was surging and rapid but fine upon deep pressure, indicating dual deficiency of blood and qi. A large dose of Shiquan Dabu Tang (Ten Complete Great Tonifying Decoction) with Shengjiang (Fresh Ginger) and Rougui (Cinnamon Bark) was administered for four doses. She then developed severe aversion to cold and teeth grinding, indicating extreme deficiency where the medicinal power had not yet reached its target. One slice of Fuzi (Prepared Aconite Lateral Root) was added to the previous prescription. After two doses, all symptoms subsided abruptly. Fuzi was removed, and after another two doses, she stabilized. Rougui and Shengjiang were discontinued, and she recovered with long-term administration.
A child presented with tidal fever, poor appetite, sallow complexion, and prolonged treatment failure after smallpox recovery. The face and extremities felt like ice after fever. I diagnosed Spleen qi deficiency and cold, recommending Liujunzi Tang (Six Gentlemen Decoction) with Shengjiang (Fresh Ginger) and Rougui (Cinnamon Bark). The patient did not believe and died; both hands and feet turned black. What a pity!
