(Zhang Jiebin, *Xin Fang Ba Zhen*) For those whose Yuan Qi (Original Qi) is insufficient, or who have endured hunger and fatigue, thereby contracting Wind-Cold external pathogens, or where the six pulses indicate that Zheng Qi (Upright Qi) cannot overcome the pathogen, it is necessary to tonify and assist the Yuan Qi while simultaneously dispersing the pathogen. Only in this way can life be preserved; this formula is suitable as the main treatment.
Chai Hu (Bupleuri Radix) (1-2 qian), Ren Shen (Ginseng Radix et Rhizoma) (2-3 qian or 5-7 qian used according to discretion), Sheng Jiang (Zingiberis Rhizoma Recens) (3-5-7 slices), Dang Gui (Angelicae Sinensis Radix), Zhi Gan Cao (Prepared Glycyrrhizae Radix et Rhizoma) (1 qian).
(Zhang Jiebin, *Xin Fang Ba Zhen*) For those with insufficient Zhong Qi (Middle Qi) where external pathogens are not dispersed, this formula is suitable as the main treatment.
Chai Hu (Bupleuri Radix) (1-2 qian), Dang Gui (Angelicae Sinensis Radix) (2-3 qian), Shu Di Huang (Rehmanniae Radix Praeparata) (3-5 qian), Bai Zhu (Atractylodis Macrocephalae Rhizoma) (2-3 qian), Shao Yao (Paeoniae Radix Alba) (1.5 qian, stir-fried), Chen Pi (Citri Reticulatae Pericarpium).
Wu Chai Hu Yin (Five Bupleuri Decoction) targets the Spleen and Stomach ("Five" corresponds to the Earth element, thus targeting the Spleen and Stomach). Shu Di, Shao Yao, Dang Gui, Chen Pi, Bai Zhu, and Gan Cao converge here. Merely dispersing external pathogens is not a complete method; one must also tonify Qi and Blood, which is most precious. (This is a modified form of Xiao Yao San (Free and Easy Wanderer Plus Four Substances Decoction). By removing Fu Ling (Poria), Bo He (Menthae Haplocalycis Herba), and Sheng Jiang, and adding Chen Pi and Shu Di, the tonification exceeds the dispersion. This formula stands in an exterior-interior relationship with Si Chai Hu Yin (Four Bupleuri Decoction). However, Si Chai Hu Yin contains more herbs for regulating the Qi aspect, whereas this one differs by concurrently tonifying Qi and Blood. Note: The above five formulas all originate from the principles of treating with Chai Hu; they are recorded here to serve as an aid for modifying established formulas. Nevertheless, being later-generation formulas, they inevitably suffer from being too general. If the disease is in the Tai Yang (Greater Yang) stage, one should use...)
(Yan Yonghe, *Ji Sheng Fang*) Treats malaria with more heat than cold, bitter taste in the mouth, dry throat, short and red urine, and a wiry and rapid pulse.
Chai Hu (Bupleuri Radix), Huang Qin (Scutellariae Radix), Ban Xia (Pinelliae Rhizoma), Gan Cao (Glycyrrhizae Radix et Rhizoma), Bai Zhu (Atractylodis Macrocephalae Rhizoma), Hou Po (Magnoliae Officinalis Cortex), Qing Pi (Citri Reticulatae Pericarpium Viride), Fu Ling (Poria), Cao Guo (Tsaoko Fructus) (equal parts). One bowl of water, one slice of Sheng Jiang (Zingiberis Rhingoma Recens).
Qing Pi Yin (Spleen-Clearing Decoction) uses Qing Pi, Hou Po, and Chai Hu, accompanied by Huang Qin, Ban Xia, Gan Cao, Fu Ling, and Bai Zhu. Adding Cao Guo along with Sheng Jiang and Da Zao (Jujubae Fructus) yields excellent results for treating Yang Malaria (malaria with predominant heat symptoms) during summer months when cooling oneself and drinking cold beverages leads to malaria.
The Stomach is often injured in such cases; therefore, Yan followed Zhang Zhongjing's Xiao Chai Hu Tang (Minor Bupleuri Decoction) to modify and establish this formula. Named "Qing Pi" (Clearing the Spleen/Stomach), it explicitly treats from the perspective of the Spleen and Stomach. In the formula, Fu Ling, Bai Zhu, Ban Xia, and Gan Cao are all herbs for the Spleen and Stomach. Additionally, Hou Po, Qing Pi, and Cao Guo are used to sweep away pathogens in the Mo Yuan (Membrane Source) and seize phlegm to intercept malaria. Its treatment of the Shao Yang (Lesser Yang) involves only Chai Hu and Huang Qin.) Malaria arises from Phlegm accumulation combined with Wind-Cold; resolving the exterior and eliminating phlegm will never fail. (Ancient texts state "No phlegm, no malaria" and "No accumulation, no malaria." However, even with phlegm accumulation, if there is no concurrent contraction of Wind-Cold, malaria may not necessarily form. Therefore, formulas for treating malaria often require the combined use of exterior-resolving and phlegm-eliminating methods.) This is a general formula for treating malaria pathogens; modifications according to circumstances are always appropriate. (This is a general formula for malaria. Huang Qin and Cao Guo in the formula can be adjusted up or down based on cold and heat patterns; do not restrict oneself to Yang Malaria alone. Furthermore, Shi Gao (Gypsum Fibrosum), Da Huang (Rhei Radix et Rhizoma), Gui Zhi (Cinnamomi Ramulus), Fu Zi (Aconiti Lateralis Radix Praeparata), Ren Shen, Shu Di Huang, Dang Gui, and Bai Shao (Paeoniae Radix Alba) can all be added according to the syndrome. If malaria persists for a long time, add Chang Shan (Dichroae Radix) and Wu Mei (Mume Fructus) to intercept it.)
