The harm caused by malaria is such that northerners suffer more severely than southerners, and the strong suffer more severely than the weak. Although it does not immediately endanger life, if left untreated, attacks will occur without cessation; if treated improperly, pathogenic evil will become internally latent, and healthy qi (Zheng Qi, 正气) will gradually weaken, eventually leading to a state where medication becomes ineffective. The three formulas I have established are very simple and easy to use. They contain no bizarre or extreme drugs, nor do they employ drastic agents like Changshan (Cortex Dichroiae, 常山) or Caoguo (Fructus Tsaoko, 草果). It is unnecessary to distinguish between Yang malaria (Yang Nue, 阳疟) and Yin malaria (Yin Nue, 阴疟), nor whether the fever occurs daily, every second day, every third day, or at irregular intervals. Regardless of the patient's age or the duration of the illness, these three formulas require no modifications; simply take them in sequence, and recovery will be immediate.
First Formula
Guang Chenpi (Exocarpium Citri Reticulatae, 广陈皮, 1 qian)
Chen Banxia (Rhizoma Pinelliae Preparated with Ginger Juice, 陈半夏, 1 qian)
Bai Fuling (Poria, 白茯苓, 1 qian)
Weilingxian (Radix Saposhnikoviae, 威灵仙, 1 qian)
Cangzhu (Rhizoma Atractylodis Macrocephalae, 苍术, 8 fen, soaked in rice wash water for one day, sliced, and stir-fried dry)
Zi Nongpo (Cortex Magnoliae Officinalis, 紫浓朴, 8 fen, stir-fried with ginger juice)
Chaihu (Radix Bupleuri, 柴胡, 8 fen)
Qingpi (Pericarpium Citri Reticulatae Viride, 青皮, 6 fen)
Binglang (Semen Arecae, 槟榔, 6 fen)
Zhi Gancao (Radix Glycyrrhizae Preparated with Honey, 炙甘草, 3 fen)
Crush the herbs into slices and process according to standard methods. Add three slices of fresh ginger, one zhong of well water, and one zhong of river water. Decoct until nine-tenths of the liquid remains. Take when hungry. Decoct the dregs again and take. If headache is present, add Baizhi (Radix Angelicae Dahuricae, 白芷, 1 qian). This formula harmonizes the intestines and stomach, eliminates phlegm, regulates qi, and removes dampness, possessing the function of guiding and opening pathways. For mild cases, two doses are sufficient for cure, and no further medication is needed. If after three doses the condition improves but does not fully resolve, proceed to the Second Formula. Take three to five doses.
Second Formula
Heshouwu (Polygoni Multiflori Radix, 何首乌, 3 qian, raw)
Guang Chenpi (Exocarpium Citri Reticulatae, 广陈皮, 8 fen)
Chaihu (Radix Bupleuri, 柴胡, 8 fen)
Bai Fuling (Poria, 白茯苓, 8 fen)
Huangqin (Radix Scutellariae, 黄芩, 8 fen)
Baizhu (Rhizoma Atractylodis Macrocephalae, 白术, 1 qian, stir-fried)
Danggui (Radix Angelicae Sinensis, 当归, 1 qian)
Weilingxian (Radix Saposhnikoviae, 威灵仙, 1 qian)
Biejia (Carapax et Plastrum Testudinis, 鳖甲, 2 qian, vinegar-processed until crisp, ground to powder)
Zhimu (Rhizoma Anemarrhenae, 知母, 2 qian)
Gancao (Radix Glycyrrhizae Preparated with Honey, 甘草, 3 fen, honey-processed)
Add three slices of fresh ginger, one zhong of well water, and one zhong of river water. Decoct until eight-tenths of the liquid remains. Add five fen of unadulterated wine, bring to a boil, and take on an empty stomach. Combine and take the second and third decoctions as well.
The brilliance of this formula lies in the combination of tonification and purgation, appropriately balancing deficiency and excess. It does not use Renshen (Radix Ginseng, 人参) or Huangqi (Radix Astragali, 黄芪). Although Changshan (Cortex Dichroiae, 常山) and Caoguo (Fructus Tsaoko, 草果) may seem ordinary, they possess miraculous effects. Even for extremely weak individuals suffering from chronic malaria, improvement will be seen after ten doses, achieving complete recovery. The notion that adding or subtracting one or two herbs renders it ineffective applies specifically to this formula.
Third Formula
Renshen (Radix Ginseng, 人参, 1 qian)
Huangqi (Radix Astragali, 黄芪, 1.2 qian, honey-processed)
Danggui (Radix Angelicae Sinensis, 当归, 1.2 qian)
Baizhu (Rhizoma Atractylodis Macrocephalae, 白术, 1 qian, stir-fried)
Guang Chenpi (Exocarpium Citri Reticulatae, 广陈皮, 8 fen)
Gancao (Radix Glycyrrhizae Preparated with Honey, 甘草, 3 fen, honey-processed)
Chaihu (Radix Bupleuri, 柴胡, 8 fen)
Shengma (Rhizoma Cimicifugae, 升麻, 4 fen, or add Heshouwu 2 qian)
Zhimu (Rhizoma Anemarrhenae, 知母, 1 qian, stir-fried, or add Qinghaozi (Fructus Artemisiae Annuae, 青蒿子, 8 fen) and Maiya (Fructus Hordei Germinatus, 麦芽, 1 qian))
Add one slice of fresh ginger and one jujube. Use two zhong of water. Decoct until eight-tenths of the liquid remains. Take when half-hungry. After three to five doses, healthy qi (Zheng Qi, 正气) will be replenished, and malaria will never recur. Although there are three formulas, the Second Formula is actually the principal one, neither harshly draining nor aggressively tonifying. The efficacy is primarily attributed to the Third Formula, which is designed for those with financial means. Poor families cannot afford ginseng; they should simply take more of the Second Formula.
