In the year of Jiashen, I was residing in a guesthouse at Xinzhou. During the long summer, I contracted heat-toxin combined with dampness, resulting in malaria occurring every other day. The chills and fever were both severe, accompanied by excessive salivary froth. Pingwei San (Stomach-Pacifying Powder) was prescribed with added Chaihu (Bupleurum Root), Zhi Banxia (Prepared Pinellia Rhizome), Shenqu (Medicated Leaven), and Chi Ling (Red Poria). After two doses, the condition resolved.
In the subsequent year of Yiyi, wind-pathogen contracted malaria developed. As stated in the classics: "When wind pathogen overflows internally, treat it with acrid-cool substances." Xiong Su Yin (Ligusticum and Perilla Drink) was used, removing Gan Ge (Dried Ginger) and Mu Xiang (Aucklandiae Radix), and adding Bo He (Menthae Haplocalycis Herba) and Jiang Pi (Zingiberis Pericarpium). After one dose, the condition resolved.
Patient Hu: Latent heat-toxin triggered chills and fever resembling malaria, dizziness, and epigastric fullness. This indicates heat-toxin carrying dampness obstructing the Qi mechanism, causing sweat only on the chest. Acrid-cool dispersal is indicated. Zhichi Tang (Gardenia and Fermented Soybean Decoction) was prescribed with added Xingren (Apricot Seed), Zhike (Aurantii Fructus), Huangqin (Scutellariae Radix), Banxia (Pinelliae Rhizoma), Gualou (Trichosanthis Fructus), and Huashi (Talcum). After several doses, the condition stabilized.
Clan woman: Heat-toxin transformed into malaria, with mild chills but intense fever, profuse sweating, dizziness, and hard stool. Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) with added Zhimu (Anemarrhenae Rhizoma) was administered, resulting in recovery.
Patient Mao: Heat-pattern had not yet resolved; additionally, pathogenic stagnation caused aversion to cold and fear of wind, chest fullness, and abdominal distension. Before noon, chills and fever resembled malaria; sweat occurred only at night. The right Guan and Chi pulses were floating and slippery. The pattern involved both exterior and interior, requiring unblocking and resolving of the channels and fu-organs. Chaihu (Bupleuri Radix), Banxia (Pinelliae Rhizoma), Bohe (Menthae Haplocalycis Herba), Sugeng (Perillae Caulis), Chenpi (Citri Reticulatae Pericarpium), Houpo (Magnoliae Officinalis Cortex), Chi Ling (Poria cum Ligno Rubrum), Shenqu (Massa Medicata Fermentata), and Shengjiang (Zingiberis Recens Rhizoma) were used. After two doses, all symptoms receded. Bohe was removed, and Huangqin (Scutellariae Radix), Sha Ren Ke (Amomi Fructus Testa), and Jineijin (Gigantidis Folliculus Intestinum) [roasted] were added. After several doses, complete recovery was achieved.
Nephew: Cold-malaria with vomiting and diarrhea, pulse slow and deficient. Lizhong Tang (Regulate the Middle Decoction) with added Banxia (Pinelliae Rhizoma), Fuling (Poria), Sha Ren (Amomi Fructus), Shenqu (Massa Medicata Fermentata), and Jiangzhi (Zingiberis Juice) was used. After one dose, vomiting and diarrhea ceased, and malaria lightened. The pulse was weak and feeble, indicating deficiency of Middle Qi. A thin gruel was recommended, followed by Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction). Spirit refreshed, appetite returned, and malaria stopped. Subsequently, Sijunzi Tang (Four Gentlemen Decoction) with added Huangqi (Astragali Radix) [roasted] and Sha Ren (Amomi Fructus) was taken, leading to cure.
Patient Li: Autumn malaria with cold back and cold limbs. From Mao hour (5-7 AM) until You hour (5-7 PM), there was cold; fever occurred at midnight without sweat, subsiding spontaneously. There was no hunger or desire to eat, and fatigue led to lying down. Following Chen Yuan Gong's Jie Han Tang (Resolve Cold Decoction), Ludangshen (Codonopsis Radix), Yuzhu (Atractylodis Macrocephalae Rhizoma), Chuan Fu Zi (Aconiti Lateralis Radix Praeparata) [roasted], Chuanxiong (Ligustici Chuanxiong Rhizoma), Chaihu (Bupleuri Radix), Guizhi (Cinnamomi Ramulus), Caoguo (Tsao-ko Fructus) [roasted and ground], Shengjiang (Zingiberis Recens Rhizoma), and Dazao (Jujubae Fructus) were decocted and taken. Sweat ensued, reducing cold. Chuan Fu Zi was removed, and Banxia (Pinelliae Rhizoma), Guya (Setariae Fructus Germinatus), Chenpi (Citri Reticulatae Pericarpium), and Danggui (Angelicae Sinensis Radix) were added. Appetite returned, and malaria stopped. (This case resembles the juvenile foot-cold malaria treated by Danxi, but that was due to sexual excess, whereas this is due to Yang deficiency.)
Patient Wang: Cough with profuse phlegm, pain in the right upper arm, malaria every other day, pulse floating and moderate. This is Lung Malaria. It resulted from exposure to wind after bathing. As the classics state: "Summer injury by heat-toxin." Profuse sweating opens the pores (Couli); encountering cold water/air in summer allows pathogenic cold to hide within the Couli and skin. Autumn wind injury then completes the disease formation. Since the Lung governs the skin and hair, it is called Lung Malaria. Chaihu Tang (Bupleurum Decoction) combined with Erchen Tang (Two-Aged Phlegm Decoction), removing Huangqin (Scutellariae Radix), and adding Fangfeng (Saposhnikoviae Radix), Sueye (Perillae Folium), Sangpi (Mori Cortex), Xingren (Armeniacae Semen Amarum), Shengjiang (Zingiberis Recens Rhizoma), and Dazao (Jujubae Fructus) was decocted and taken. After several doses, recovery occurred.
Nephew: Intermittent malaria with severe chills and fever, headache, cold back, numbness in limbs, rib-side oppression, vomiting, nausea, and profuse phlegm, caused by damp-heat obstructing the Qi mechanism. Baisharen (Amomi Fructus Rotundus) and Houpo (Magnoliae Officinalis Cortex) [each 0.5 qian], Guangpi (Citri Reticulatae Pericarpium) and Zhike (Aurantii Fructus) [each 1 qian], Banxia (Pinelliae Rhizoma) and Fuling (Poria) [each 2 qian], Qinghao (Artemisiae Annuae Herba) [0.8 fen], Xingren (Armeniacae Semen Amarum) [1.5 qian], Gualou (Trichosanthis Fructus) and Zhuru (Bambusae Caulis in Taedia) [each 1.2 qian], Weijiang (Roasted Ginger) [2 qian]. After one dose, epigastric oppression eased, vomiting and nausea ceased, phlegm descended, bowels moved, damp-heat cleared, and malaria stopped. Next prescription: Xingren (Armeniacae Semen Amarum) and Banxia (Pinelliae Rhizoma) [each 1.5 qian], Chi Ling (Poria cum Ligno Rubrum) [2 qian], Gualou (Trichosanthis Fructus), Zhike (Aurantii Fructus), Juhong (Citri Reticulatae Pericarpium Rubrum), Ganju (Chrysanthemi Indici Flos) [each 0.8 fen], Coren (Amomi Fructus Rotundus) [0.3 fen], Zhuru (Bambusae Caulis in Taedia) [1 qian], Nensangye (Mori Folium Tender) [3 qian]. After one dose, malaria stopped. Previously, Wendan Tang (Warm Gallbladder Decoction) cured the malaria, but appetite remained poor, defecation difficult, and epigastric comfort lacking, indicating disharmony at the left Guan position. Consequently, the intestines and fu-organs failed to descend. Treatment aimed to harmonize Jueyin and Yangming. Baishao (Paeoniae Radix Alba), Xuanjinhua (Inulae Flos), Chenpi (Citri Reticulatae Pericarpium), Banxia (Pinelliae Rhizoma), Gualouren (Trichosanthis Semen), Muli Fen (Concha Ostreae Pulvis), Xingren (Armeniacae Semen Amarum), Zhuru (Bambusae Caulis in Taedia), and Zhishi Zhi (Zhitzi Juice) were taken. After further doses, everything normalized.
Clan grandson: Fetal malaria stagnation. Cunjin Dan (Inch Gold Pill) 3 qian, taken with ginger soup, cured after two administrations.
Patient Ben: Intermittent malaria with migratory headache extending to teeth, nighttime irritability and insomnia. The pattern arises from Gallbladder fire rising and agitating the Heart Master, causing mental confusion and disordered speech. It is necessary to extinguish Wind-Fire in the Gallbladder collaterals for the malaria pathogen to resolve naturally. Gouteng (Uncariae Ramulus cum Uncis) and Biejia (Testudinis Carapax et Plastrum) [each 2 qian], Shanzhi (Gardeniae Fructus), Danpi (Moutan Cortex), Maidong (Ophiopogonis Radix) [each 1 qian], Huangqin (Scutellariae Radix), Lianqiao (Forsythiae Fructus) [each 0.7 fen], Banxia (Pinelliae Rhizoma) [stir-fried with green salt, 1.5 qian], Yejiaoteng (Polygoni Multiflori Caulis) [5 qian]. Taken twice daily, along with Niuhuang Qingxin Wan (Calculus Bovis Heart-Clearing Pills). Malaria lightened. Changed to Wumei (Mume Fructus) [2 pieces], Chi Ling (Poria cum Ligno Rubrum), Sheng Shouwu (Polygoni Multiflori Radix) [each 3 qian], Biejia (Testudinis Carapax et Plastrum) [2 qian], Niuxi (Achyranthis Bidentatae Radix), Danggui (Angelicae Sinensis Radix), Danpi (Moutan Cortex) [each 0.8 fen]. One sip stopped the malaria.
Ms. Liang: Native of Guangdong, where local qi tends to dissipate. Residing north of the Yellow River, the climate and geography differed significantly. This summer and autumn, steaming rain created humid conditions, leading to pathogenic infection and malaria with chills, fever, irritability, fullness, and slight sweat. Treated as damp-malaria. Following ancient Chaiping Tang (Bupleurum and Pingwei Decoction), Chaihu (Bupleuri Radix), Huangqin (Scutellariae Radix), Banxia (Pinelliae Rhizoma), Fuling (Poria), Zhike (Aurantii Fructus), Shanzhi (Gardeniae Fructus), Maoyu (Atractylodis Rhizoma) [raw], Houpo (Magnoliae Officinalis Cortex), Chenpi (Citri Reticulatae Pericarpium), Shengjiang (Zingiberis Recens Rhizoma), and Dazao (Jujubae Fructus) were used. After two doses, sweat penetrated, chills and fever reduced. Switched to clearing summer-heat and expelling pathogens. Removed Maoyu, Houpo, and Zhike from the previous formula, added Qinghao (Artemisiae Annuae Herba), Xiangru (Elsholtziae Herba), and Bohe (Menthae Haplocalycis Herba). After another two doses, recovery was achieved.
Certain patient: Malaria every other day, heavy chills and light fever, profuse sweat, spiritual fatigue. At onset, no headache, no thirst, only severe cold rigidity, cold limbs, and sore thighs. An elderly person with Qi deficiency and phlegm; this is neither summer-heat nor wind, but deficient pathogen entering the collaterals, named Labor Malaria. Initially fasting, then taking Baoyuan Tang (Preserve the Origin Decoction) to support Righteous Qi and expel collateral pathogens. Renshen (Ginseng Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), Gancao (Glycyrrhizae Radix), Danggui (Angelicae Sinensis Radix), Chenpi (Citri Reticulatae Pericarpium), Biejia (Testudinis Carapax et Plastrum) [roasted], Chaihu (Bupleuri Radix), Banxia (Pinelliae Rhizoma), Weilingxian (Sinomenii Caulis), and Shengjiang (Zingiberis Recens Rhizoma) were decocted. One sip stopped the malaria.
