（有风、有暑、有食、老疟、疟母、痰病。）
老疟病∶此系风暑入阴分。在脏用血药∶川芎、抚芎、红花、当归，加苍术、白术、白芷、黄柏、甘草煎。
露一宿，次早服之。无汗要有汗，散邪为主，带补。有汗要无汗，正气为主，带散。有疟母者，用丸药消导，
醋煮鳖甲为君，三棱、蓬术、香附随证加减。
三日一发者，受病一年。间发者，受病半年。一日一发者，受病一月。连二日发者，住一日者，气血俱受
病。一日间一日者，补药带表。药后用疟丹截之。在阴分者用药彻起，在阳分方可截之。
又方∶
草果 知母 槟榔 乌梅 常山 甘草（炙） 穿山甲（炮） 用水酒一大碗，煎至半碗，露一宿。临发
日前二时，温服。如吐，则顺之。
截疟青蒿丸∶
青蒿（一两） 冬青叶（二两） 马鞭草（二两） 官桂（二两）
上三叶，皆晒干，秤为末，法丸如胡椒子大。每两作四服。于当发前一时服尽。
大法∶暑风必当发汗。夏月多在风凉处歇，遂闭其汗，而不泄。因食者，从食上治。
疟而虚者，须先用参术一二帖，托住其气不使下陷，后用他药。治内伤挟外邪者同法。内必主痰，必以
汗解，二陈汤加常山、柴胡、黄芩、草果。
疟而甚者，发寒热、头痛如破、渴而饮水、自汗。可与参、 、术、苓、连、栀子、川芎、苍术、半夏等治。
久病疟，二陈汤加川芎、苍术、柴胡、葛根、白术，一补一发。
（疟疾的病因包括风邪、暑邪、饮食积滞，以及病程较长的老疟、形成结块的疟母、痰湿引起的疟病。）
老疟：这是由于风邪和暑邪侵入阴分所致。治疗在脏者使用补血药：川芎、抚芎、红花、当归，加入苍术、白术、白芷、黄柏、甘草煎煮。
煎好后放置一夜，次日清晨服用。无汗的情况需要发汗，以疏散邪气为主，兼以补益；有汗的情况需要止汗，以扶助正气为主，兼以疏散。如果有疟母（疟疾日久形成的腹部结块），使用丸药进行消导，以醋煮鳖甲为君药，三棱、蓬术、香附根据证候加减。
每隔三日发作一次的，说明受病已一年。间歇发作的，说明受病已半年。每日发作一次的，说明受病已一月。连续发作两天后停一天的，说明气血都受到了病邪侵害。隔日发作一次的，用补药兼以解表。服药后用“疟丹”来截断疟疾。病在阴分的，用药将其透达出阳分后，才可以截断疟疾。
另一个方子：
草果、知母、槟榔、乌梅、常山、炙甘草、炮穿山甲。用水一大碗和酒一大碗，煎至半碗，放置一夜。在疟疾发作前两小时，温服。如果引起呕吐，则顺应其势让其吐出。
截疟青蒿丸：
青蒿（一两）、冬青叶（二两）、马鞭草（二两）、官桂（二两）。
以上三种叶子，都要晒干，称量后研成粉末，按照传统方法制成如胡椒粒大小的丸药。每两药粉分为四次服用。在疟疾发作前一小时服完。
治疗大法：暑风和疟疾应当发汗。夏季多在风凉处休息，导致汗液闭塞而不能排泄。因饮食积滞引起的，从调理饮食入手治疗。
疟疾而体质虚弱的，须先用党参、白术一二剂，托住正气使其不致下陷，然后再用其他药物。治疗内伤兼夹外邪的方法与此相同。体内必然主痰，必须通过发汗来解除，可用二陈汤加常山、柴胡、黄芩、草果。
疟疾严重的，出现寒热往来、头痛如裂、口渴想喝水、自汗。可以用人参、[缺字]、白术、茯苓、黄连、栀子、川芎、苍术、半夏等药物治疗。
久患疟疾，用二陈汤加川芎、苍术、柴胡、葛根、白术，一边补益一边发散。
(The etiologies of malaria include wind pathogen, summerheat pathogen, food stagnation, as well as chronic malaria (Lao Nue), malaria mass (Nue Mu), and phlegm-induced malaria.)
Chronic Malaria: This is caused by the invasion of wind and summerheat pathogens into the Yin aspect. For cases involving the Zang organs, blood-nourishing herbs are used: Chuanxiong Rhizoma (Chuanxiong), Xiongchuang Rhizoma (Fuxiong), Carthamus Flos (Honghua), Angelicae Sinensis Radix (Danggui), added with Atractylodis Macrocephalae Rhizoma (Cangzhu), Atractylodis Rhizoma (Baizhu), Angelicae Dahuricae Radix (Baizhi), Phellodendri Cortex (Huangbai), and Glycyrrhizae Radix et Rhizoma (Gancao) for decoction.
After decoction, leave it exposed overnight and take it warm the next morning. In cases without sweating, induce sweating to primarily disperse pathogens while accompanying with tonification; in cases with sweating, stop sweating to primarily support healthy Qi while accompanying with dispersion. If a malaria mass (abdominal lump formed after long-standing malaria) exists, use pill preparations for resolution and guidance, using Vinegar-processed Trionycis Carapax (Biejia) as the sovereign herb, with Sparganii Rhizoma (Sanleng), Curcumae Aestivae Rhizoma (Pengru), and Cyperi Rhizoma (Xiangfu) added or subtracted according to the syndrome.
Those who have an attack every three days have been sick for one year. Those with intermittent attacks have been sick for half a year. Those with daily attacks have been sick for one month. Those who attack for two consecutive days and then rest for one day indicate that both Qi and Blood are diseased. Those with attacks every other day should be treated with tonifying herbs accompanied by exterior-releasing herbs. After taking medicine, use "Malaria Intercepting Powder" (Nue Dan) to intercept the malaria. For diseases in the Yin aspect, use medication to bring them out to the Yang aspect before they can be intercepted.
Another prescription:
Tsaoko Fructus (Caoguo), Anemarrhenae Rhizoma (Zhimu), Arecae Semen (Binglang), Mume Fructus (Wumei), Dichroae Radix (Changshan), Roasted Glycyrrhizae Radix et Rhizoma (Zhi Gancao), and Processed Manis Squama (Pao Shanjia). Decoct with one large bowl of water and one large bowl of wine until half a bowl remains, leave exposed overnight. Take warm two hours before the onset of malaria. If vomiting occurs, allow it to vomit naturally.
Qinghao Pill for Intercepting Malaria:
Artemisiae Annuae Herba (Qinghao, 1 liang), Ilicis Aquifolii Folium (Dongqingye, 2 liang), Verbena Officinalis Herba (Mabiancao, 2 liang), Cinnamomi Ramulus (Guangui, 2 liang).
Dry the above three leaves thoroughly, weigh them, and grind into powder. Form pills the size of pepper seeds according to standard methods. Divide each liang of powder into four doses. Take all at once one hour before the expected onset of malaria.
General Principle: Summerheat and wind must be treated by inducing sweating. In summer, resting in cool, breezy places often causes sweat pores to close, preventing perspiration from being excreted. For cases caused by food stagnation, treat from the perspective of digestion.
For malaria patients with deficiency, first administer one or two doses of Codonopsis Radix (Renshen) and Atractylodis Rhizoma (Baizhu) to support the Qi and prevent sinking, then use other medications. The method is the same for treating internal injury complicated by external pathogens. Internally, phlegm is usually the primary factor; it must be resolved through sweating. Use Erchen Tang (Two-Aged Decoction) added with Dichroae Radix (Changshan), Bupleuri Radix (Chaihu), Scutellariae Radix (Huangqin), and Tsaoko Fructus (Caoguo).
For severe malaria presenting with alternating chills and fever, headache as if splitting, thirst with desire to drink water, and spontaneous sweating, treat with Ren Shen, [missing character], Baizhu, Poria (Fuling), Coptidis Rhizoma (Lian), Gardeniae Fructus (Zhizi), Chuanxiong Rhizoma (Chuanxiong), Cangzhu, and Pinelliae Rhizoma (Banxia).
For long-standing malaria, use Erchen Tang added with Chuanxiong Rhizoma (Chuanxiong), Cangzhu, Bupleuri Radix (Chaihu), Puerariae Radix (Gegen), and Atractylodis Rhizoma (Baizhu), combining tonification with dispersion.
