甲、概况
疟疾一证,通常皆寒热交作,起迄有时。亦有名之为 疟者,则夜发曰 ,昼发曰疟也。其病有寒多热
少者,有热多寒少者,有但寒而热甚微者,有但热而寒甚微者,其间虽有寒热多少之不同,隐显之各异,然
为寒热交作而起迄有时则一也,故均属于疟。疟之一日一作者为轻,间日一作者为重,三日而作一次者
是为最深,多由久疟失治所致。又疟疾之寒热多少不平者亦为较重,疟之热势不清者亦为较重,疟之由重而渐
轻,大率为寒热由不平而渐平均,由期长而渐缩短,反之则为病方增也。疟疾之起源,虽由时令之偏,然感之
而足以致病者,必其身体有预伏之因,交相为疟以成功,或预伏暑邪,成为暑疟,或预伏湿邪,成为湿疟,或
预伏风邪,成为风疟,或预伏寒邪,成为寒疟;而积痰积食,亦多能致疟。伏邪重者疟亦重,伏邪轻者疟亦
轻,故秋深之疟,恒较夏日为重,以伏邪重,故一发则缠绵而不易愈也。又疟疾之轻重,更须视脾胃之强弱,
脾胃强则卫气振作而能鼓邪以外出,脾胃弱则卫气不振而使病邪得久留,故疟疾之易愈与否,又常视脾胃之
强弱与否以为断也。此病当发作之时,为病邪乘机以外出,故治疟得当者,当使其每发一次,则病邪减退一
次,庶几渐发渐轻而易愈,否则截疟过早,则有闭塞邪气之患,截疟过迟,则有元气衰惫之虑,是不可
不慎之于始也。
乙、治法
疟疾之治法,初起常为疏导开泄,而疏导开泄之中,则宜分别其暑湿风寒之因,辨其热重寒重之状,
对证以下药。大率因暑而发者,但热而少寒,体若燔炭,烦渴而呕,便艰或傍流,治宜
清凉之剂。有汗者人参白虎汤加减,无汗者香薷饮加减。通治宜
杏仁、滑石、淡竹叶、花粉、麦冬、知母、川贝、陈皮、甘草;湿重痰多,宜以二陈汤出入为法;热重烦躁,
宜加淡豆豉、石膏之属。因湿而发者,多身体沉重,小便不利,呕逆胀满,舌腻或糙,治宜解表除湿,湿重而
痰多热少者,用胃苓汤加羌活、柴胡、紫苏之类;湿渐化热者,用四苓散加减;湿已化热者,用桑叶、菊花、
银花、连翘、薄荷等轻清之剂,湿重化热者则从热治。因风而发者,多烦躁头疼,恶风自汗,或先热而后寒,
治宜解表泄风,用半夏、柴胡、羌活、紫苏、川芎、细辛、白芷、槟榔、生姜之属,若唇舌干燥口渴,不宜过
用燥剂者,用桂枝汤加桑叶、银花之类和之;因寒而发者,但寒无热,或寒多热微,头项腰背疼痛,治宜辛温
解散,用柴胡桂枝干姜汤,寒盛而痰多者加常山、草果、槟榔、浓朴之属。虚者数发后即用附子理中汤。
至于治疟总法,有疟疾第一方、疟疾第二方、疟疾第三方,可以量证酌用。通治之方又有二陈汤与平胃散,因
疟不离乎痰湿,故以治痰治湿为主也。又有小柴胡汤,因疟不离乎少阳,故治从少阳和之也。然平胃偏燥,热
甚者宜加黄芩、黄连、青皮之属;小柴胡汤有补,初病者宜去人参、甘草、大枣之属。而黄芩、黄连不宜于寒
证,附子、干姜不宜于热证,初起必宜发表,久疟宜顾脾胃,此皆不可不知者也。又凡疟之一日一作者,因其
暑湿风寒,酌用疏导开泄之剂,数服可愈;疟之间日一作者,开泄之后,宜用四君子汤、补中益气汤之类扶其
正气,则庶可有济;疟之三日一作者,谓之三阴疟,必须补气养血,外贴三阴疟疾膏,疟乃可止,疟愈之后,
仍须用八珍汤或人参养荣汤出入以为培补,否则难免有复发之虑也。又疟疾经久,结为 瘕,在于胁际者谓之
疟母,治宜疟母丸,或鳖甲煎丸以化之。脾虚不任攻伐者,宜补中益气汤加鳖甲。总之疟之热重而实至于便结谵
语者,亦可用硝、黄攻下,疟之虚而寒热微微往来者,亦可用参、 峻
补,固非仅疏导开泄之法,一成到底而不变者也。余如热多寒少
之疟亦名瘅疟,热高而不觉其寒者,亦名温疟,但寒少热者,亦名牝疟,脾虚而呕吐痰水者,亦名痰疟,腹大
而疼,饥不欲食者亦名食疟,立名虽异,而治法固不脱乎上述以为之变化也。又小儿初次患疟,谓之胎疟,
既不可截疟过早,更不可迁延过久,必须培养尽善,庶免脾胃受伤,腹胀肌瘦,浸假入于怯损之途也。

甲、概况
疟疾这一病症,通常表现为寒热交替发作,且有固定的发作和停止时间。也有将其称为“瘅”的,其中夜间发作的称为“瘅”,白天发作的称为“疟”。疟疾的病证有寒多热少的,有热多寒少的,有只有寒冷而发热极轻微的,有只有发热而寒冷极轻微的。虽然其间寒热的多少不同,隐显各异,但都是寒热交替发作且起止有时,所以都归属于疟疾。疟疾每天发作一次的为轻症,隔一天发作一次的重一些,每三天发作一次的是最深重的,多由长期患疟疾失治所致。另外,疟疾中寒热程度不平衡的也属于较重,疟疾发热势态不清晰的也属于较重。疟疾由重转轻,大体上是寒热由不平衡逐渐变得平均,发作间隔由长逐渐缩短;反之,则是病情正在加重。疟疾的起源,虽然是由时令气候偏颇引起,但感受邪气而足以致病的,必定是身体内有预先潜伏的因素,两者交互作用才导致疾病发生。或者体内预伏暑邪,形成暑疟;或者预伏湿邪,形成湿疟;或者预伏风邪,形成风疟;或者预伏寒邪,形成寒疟;而积痰和积食,也多能导致疟疾。潜伏的邪气重,疟疾也就重;潜伏的邪气轻,疟疾也就轻。所以深秋时的疟疾,往往比夏天的严重,因为潜伏的邪气重,所以一旦发作就缠绵难愈。此外,疟疾的轻重,还必须看脾胃的强弱。脾胃强盛,则卫气(人体防御外邪的气)振奋,能够鼓动邪气向外排出;脾胃虚弱,则卫气不振,使病邪得以久留体内。所以疟疾是否容易痊愈,常以脾胃的强弱作为判断依据。此病在发作的时候,是病邪乘机向外排出的过程,所以治疗疟疾得当的话,应当使其每次发作时,病邪就减退一次,这样渐渐发作、渐渐减轻,就容易痊愈。否则,截断疟疾过早,会有闭塞邪气的祸患;截断疟疾过迟,则有元气衰败疲惫的忧虑,这是开始治疗时不可不慎重的。
乙、治法
疟疾的治疗方法,初起时常采用疏导开泄的方法,而在疏导开泄之中,则应当分别其因暑、湿、风、寒的不同病因,辨别其热重或寒重的症状,针对证候来用药。大体上因暑邪引发的,表现为只有发热而少寒,身体像燃烧的炭火一样烫,心烦口渴且呕吐,大便干结或出现旁流(痢疾样腹泻),治疗宜用清凉的方剂。有汗的用白虎加人参汤加减,无汗的用香薷饮加减。通用的药物包括杏仁、滑石、淡竹叶、天花粉、麦冬、知母、川贝母、陈皮、甘草;如果湿气重痰多,宜以二陈汤为基础进行加减;如果热重烦躁,宜加入淡豆豉、石膏之类的药物。因湿邪引发的,多表现为身体沉重,小便不利,恶心呕吐,腹胀满,舌苔腻或粗糙,治疗宜解表除湿。湿气重而痰多热少的,用胃苓汤加羌活、柴胡、紫苏等药;湿气逐渐化热的,用四苓散加减;湿气已经完全化热的,用桑叶、菊花、金银花、连翘、薄荷等轻清的药物,湿气重且已化热的则按热证治疗。因风邪引发的,多表现为烦躁头痛,怕风自汗,或先发热而后发冷,治疗宜解表祛风,用半夏、柴胡、羌活、紫苏、川芎、细辛、白芷、槟榔、生姜等药;如果嘴唇舌头干燥口渴,不宜过多使用燥烈药物的,用桂枝汤加桑叶、金银花等调和。因寒邪引发的,只有寒冷没有发热,或寒多热微,头项腰背疼痛,治疗宜辛温解散,用柴胡桂枝干姜汤,寒盛且痰多的加常山、草果、槟榔、厚朴等药。体质虚弱的,数次发作后即用附子理中汤。
至于治疗疟疾的总法,有疟疾第一方、疟疾第二方、疟疾第三方,可以根据证候斟酌使用。通用的方剂又有二陈汤和平胃散,因为疟疾离不开痰湿,所以以治痰治湿为主。还有小柴胡汤,因为疟疾离不开少阳经,所以治疗从少阳经和解入手。然而平胃散偏于燥烈,热势严重的宜加黄芩、黄连、青皮等药;小柴胡汤有补益作用,初病患者宜去掉人参、甘草、大枣等补益之品。而黄芩、黄连不适合寒证,附子、干姜不适合热证,初起必须发表,久疟要注意顾护脾胃,这些都是不可不知道的。另外,凡是疟疾每天发作一次的,因其暑湿风寒,酌情使用疏导开泄的方剂,服用几副即可痊愈;疟疾隔一天发作一次的,开泄之后,宜用四君子汤、补中益气汤之类扶助正气,这样或许能有疗效;疟疾每三天发作一次的,称为三阴疟,必须补气养血,外用贴敷三阴疟疾膏,疟疾才能停止。疟疾痊愈后,仍须用八珍汤或人参养荣汤加减以培补元气,否则难免有复发的忧虑。另外,疟疾经久不愈,结块成为癥瘕,位于胁肋部位的称为疟母,治疗宜用疟母丸,或鳖甲煎丸来化解它。脾虚不能耐受攻伐的,宜用补中益气汤加鳖甲。总之,疟疾热重且实证导致大便干结、说胡话的,也可以用硝石、大黄攻下;疟疾虚证且寒热轻微往来的,也可以用参、芪峻补,这固不仅仅是疏导开泄这一种方法,一成不变到底的。其余如热多寒少的疟疾也称为瘅疟,热度高而不觉得冷的,也称为温疟,只有寒少热的,也称为牝疟,脾虚而呕吐痰水的,也称为痰疟,腹部大且疼痛,饿了不想吃东西的也称为食疟。虽然名称各异,但治疗方法确实不离乎上述原则的变化。另外,小儿初次患疟疾,称为胎疟,既不可以截疟过早,更不可以拖延过久,必须培养调理尽善尽美,以免损伤脾胃,导致腹胀肌肉消瘦,逐渐陷入虚损的境地。

A. Overview
Malaria (Nüe, 疟疾) is typically characterized by alternating chills and fever, with regular onset and cessation times. Some refer to it as "Dan" (Dàn, 瘅), where night-onset is called Dan, and day-onset is called Malaria. The condition may present with more chills than fever, more fever than chills, only chills with very slight fever, or only fever with very slight chills. Although the degree of chills and fever varies, and their manifestation differs, they all share the characteristic of alternating chills and fever with regular timing; thus, they are all classified under Malaria. Malaria occurring daily is considered mild; occurring every other day is heavier; occurring once every three days is the deepest and most severe, often resulting from neglected long-term malaria. Furthermore, imbalance in the degree of chills and fever indicates a heavier condition, as does unclear fever intensity. A transition from severe to mild malaria generally involves the chills and fever becoming balanced and the interval between attacks shortening; conversely, this indicates worsening disease.
The origin of malaria lies in seasonal climatic abnormalities, but for pathogenic factors to cause disease, there must be pre-existing latent factors within the body interacting with them. These include latent Summer-heat (Shu, 暑邪) forming Summer-heat Malaria, latent Dampness (Shi, 湿邪) forming Dampness Malaria, latent Wind (Feng, 风邪) forming Wind Malaria, or latent Cold (Han, 寒邪) forming Cold Malaria. Accumulated Phlegm (Tan, 痰) and Food Stagnation (Shi, 食积) can also induce malaria. Heavier latent pathogens result in heavier malaria, while lighter ones result in milder cases. Therefore, late-autumn malaria is often more severe than summer malaria because the heavy latent pathogens lead to lingering, difficult-to-cure conditions. Additionally, the severity depends on the strength of the Spleen and Stomach (Pi Wei, 脾胃). Strong Spleen and Stomach Qi allows Wei Qi (Wei Qi, 卫气) to rise and expel pathogens outward; weak Spleen and Stomach fails to support Wei Qi, allowing pathogens to remain. Thus, recovery depends on Spleen and Stomach strength. During an attack, pathogens attempt to exit; effective treatment should reduce pathogenic load with each attack, leading to gradual recovery. Prematurely stopping the malaria risks trapping pathogens, while delaying too long risks exhausting Yuan Qi (Yuan Qi, 元气).
B. Treatment Methods
Initial treatment of malaria usually involves guiding and venting (Shu Dao Kai Xie, 疏导开泄). Within this approach, one must distinguish between Summer-heat, Dampness, Wind, and Cold etiologies, and differentiate between heat-dominant and cold-dominant presentations to prescribe appropriate herbs.
1. Summer-heat Malaria: Characterized by fever without significant chills, burning body heat, irritability, thirst, vomiting, constipation or dysentery-like diarrhea. Treatment requires cooling agents. For those with sweat, use Baihu Jia Renshen Tang (Gypsum and Ginseng Decoction) modified; for those without sweat, use Xiangru Yin (Elsholtzia Decoction) modified. Common herbs include Xing Ren (Apricot Seed), Hua Shi (Talcum), Dan Zhu Ye (Lophatherum Leaf), Tian Hua Fen (Trichosanthes Root), Mai Dong (Ophiopogon Tuber), Zhi Mu (Anemarrhena Rhizome), Chuan Bei Mu (Fritillaria Bulb), Chen Pi (Tangerine Peel), and Gan Cao (Licorice Root). If dampness is heavy with much phlegm, modify Er Chen Tang (Two-Cured Decoction); if heat and irritability are heavy, add Dan Dou Chi (Fermented Soybean) and Shi Gao (Gypsum).
2. Dampness Malaria: Characterized by heavy body, difficult urination, nausea, abdominal distension, greasy or rough tongue coating. Treatment requires releasing the exterior and resolving dampness. For heavy dampness with much phlegm and little heat, use Weiling Tang (Gastrodia and Poria Decoction) plus Qiang Huo (Notopterygium Rhizome), Chai Hu (Bupleurum Root), and Zi Su (Perilla Leaf). As dampness transforms into heat, use Si Ling San (Four-Poria Powder) modified. Once fully transformed into heat, use light, clearing herbs like Sang Ye (Mulberry Leaf), Ju Hua (Chrysanthemum Flower), Yin Hua (Honeysuckle Flower), Lian Qiao (Forsythia Fruit), and Bo He (Mint). Heavy dampness transforming into heat is treated as a heat pattern.
3. Wind Malaria: Characterized by irritability, headache, aversion to wind, spontaneous sweating, or fever preceding chills. Treatment requires releasing the exterior and dispersing wind, using Ban Xia (Pinellia Tuber), Chai Hu, Qiang Huo, Zi Su, Chuan Xiong (Szechwan Lovage Rhizome), Xi Xin (Asarum Root), Bai Zhi (Angelica Dahurica Root), Bing Lang (Areca Seed), and Sheng Jiang (Fresh Ginger). If lips and tongue are dry with thirst, avoid overly drying agents; instead, use Guizhi Tang (Cinnamon Twig Decoction) plus Sang Ye and Yin Hua to harmonize.
4. Cold Malaria: Characterized by chills without fever, or more chills than slight fever, pain in head, neck, waist, and back. Treatment requires acrid-warm dispersion, using Chaihu Guizhi Ganjiang Tang (Bupleurum, Cinnamon Twig, and Dried Ginger Decoction). For severe cold with much phlegm, add Chang Shan (Daphne Genkwa Bark), Cao Guo (Black Cardamom), Bing Lang, and Hou Po (Magnolia Bark). For deficiency patterns after multiple attacks, use Fuzi Lizhong Tang (Aconite and Magnolia Root Decoction).
General formulas include Malaria Formula No. 1, No. 2, and No. 3, selected based on presentation. Er Chen Tang and Pingwei San (Peaceful Stomach Powder) are used because malaria is linked to phlegm and dampness. Xiao Chaihu Tang (Minor Bupleurum Decoction) is used because malaria involves the Shaoyang (Lesser Yang) channel. Note: Pingwei San is drying; add Huang Qin (Scutellaria Root), Huang Lian (Coptis Rhizome), and Qing Pi (Aged Tangerine Peel) for severe heat. Xiao Chaihu Tang is tonifying; remove Ren Shen (Ginseng Root), Gan Cao, and Da Zao (Jujube) for initial acute cases. Huang Qin/Lian are unsuitable for cold patterns; Fu Zi (Aconite Root) and Gan Jiang (Dried Ginger) are unsuitable for heat patterns. Initial stages require releasing the exterior; chronic malaria requires protecting the Spleen and Stomach.
Daily malaria responds to guiding/venting formulas. Every-other-day malaria requires Si Jun Zi Tang (Four Gentlemen Decoction) or Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) after venting to support Zheng Qi (Upright Qi). Three-day malaria (San Yin Nüe, 三阴疟) requires tonifying Qi and Blood, plus external application of San Yin Malaria Plaster. Post-recovery, use Bazhen Tang (Eight-Treasure Decoction) or Renshen Yangrong Tang (Ginseng and Nutrient-Qi Decoction) to prevent relapse. Chronic malaria forming masses in the hypochondrium is called Mumai (Mǔmài, 疟母), treated with Mumai Wan (Malaria Mass Pill) or Biejia Jian Wan (Soft-Shelled Turtle Pill). If Spleen deficiency prevents aggressive treatment, use Buzhong Yiqi Tang plus Biejia (Soft-shelled Turtle Shell). Severe heat with constipation and delirium may require Xiaoshi (Mirabilite) and Dahuang (Rhubarb Root) for purging. Deficiency with mild alternating chills/fever may require Renshen and Huang Qi (Astragalus Root) for strong tonification.
Other types include Dan Malaria (Heat > Cold), Wen Malaria (High heat, no cold sensation), Pin Malaria (Cold > Heat), Tan Malaria (Spleen deficiency with phlegm-water vomiting), and Shi Malaria (Abdominal distension/pain, anorexia). Pediatric first-time malaria is called Tai Malaria (Fetal Malaria); it must not be stopped too early nor delayed too long, requiring careful nurturing to prevent Spleen/Stomach damage and emaciation.
