赵以德曰∶知母性寒，入足阳明，治独胜之热，使退就太阴，草果温燥，治足太阴
独胜之寒，使退就阳明，二经和，则无阴阳交争之变，是为君药；常山主寒热疟，吐胸
中痰结，是为臣药∶甘草和诸药，乌梅收敛，生津退热，贝母去痰，除结散郁，槟榔
除痰癖，破滞气，是为佐药；穿山甲穴山而居，遇水而入，乃能出入阴阳，贯穿经络于
荣分，以破暑结之邪，为使药也。惟脾胃有郁痰者，用之收功效。
To treat malaria that occurs every two or three days.
Take one *jin* (approx. 500g) of *Changshan* (*Dichroa Radix*, 常山), soaked in vinegar for five days in spring, three days in summer, seven days in autumn, and ten days in winter; four *liang* (approx. 125g) each of *Binglang* (*Arecae Semen*, 槟榔), *Banxia* (*Pinelliae Rhizoma Praeparatum cum Alumine et Zingibere*, 半夏), and *Beimu* (*Fritillariae Bulbus*, 贝母). Grind into fine powder, mix with egg white and wheat flour paste to form pills the size of tung tree seeds. Take thirty pills per dose, swallowed with cold wine late at night before sleep. Administer another dose early the next morning.
This formula is miraculous; it stops malaria that has persisted for years upon administration.
*Ren Shen* (*Ginseng Radix et Rhizoma*, 人参) (8 fen), *Bai Zhu* (*Atractylodis Macrocephalae Rhizoma*, 白术) (stir-fried until yellow, 1 qian), *Qing Pi* (*Citri Reticulatae Pericarpium Viride*, 青皮) (4 fen), *Chen Pi* (*Citri Reticulatae Pericarpium*, 陈皮) (6 fen), *Zhu Ling* (*Polyporus*, 猪苓) (4 fen), *Ze Xie* (*Alismatis Rhizoma*, 泽泻) (4 fen), *Gan Cao* (*Glycyrrhizae Radix et Rhizoma*, 甘草) (3 fen), *Chai Hu* (*Bupleuri Radix*, 柴胡) (6 fen), *Huang Qin* (*Scutellariae Radix*, 黄芩) (8 fen), *Fu Ling* (*Poria*, 茯苓) (8 fen), *Ban Xia* (*Pinelliae Rhizoma Praeparatum cum Alumine et Zingibere*, 半夏) (8 fen), *Chang Shan* (*Dichroa Radix*, 常山) (stir-fried with wine, 6 fen), *Cao Guo* (*Tsaoko Fructus*, 草果) (6 fen), *Jiang Pi* (*Zingiberis Pericarpium*, 姜皮) (3 slices), *Da Zao* (*Jujubae Fructus*, 枣) (2 pieces). Decoct with water until reduced to 70% volume. Take on the eve of the fever onset during the wu geng period (3-5 AM).
Malaria in its initial stage should not be forcibly arrested; doing so leaves pathogenic factors unresolved, potentially leading to other complications. For chronic malaria that does not resolve, use this formula to arrest the attack.
*Chang Shan* (*Dichroa Radix*, 常山) (stir-fried with strong liquor, 2 qian), *Cao Guo* (*Tsaoko Fructus*, 草果) (roasted), *Bing Lang* (*Arecae Semen*, 槟榔), *Zhi Mu* (*Anemarrhenae Rhizoma*, 知母) (each 1 qian), *Bei Mu* (*Fritillariae Bulbus*, 贝母) (1.5 qian), *Wu Mei* (*Mume Fructus*, 乌梅) (1 qian; another version includes *Chuanshanjia* (*Manis Squama*, 穿山甲)), *Sheng Jiang* (*Zingiberis Rhizoma Recens*, 姜) (3 slices), *Da Zao* (*Jujubae Fructus*, 枣) (1 piece). Decoct with half water and half liquor. Leave exposed overnight. Take warm facing east on an empty stomach before sunrise. Decoct the dregs again with liquor and take when the malaria is about to start.
Zhao Yi-de stated: *Zhi Mu* (*Anemarrhenae Rhizoma*, 知母) is cold in nature and enters the Foot-Yangming Stomach Meridian to treat excessive heat, guiding it back to the Taiyin Spleen; *Cao Guo* (*Tsaoko Fructus*, 草果) is warm and dry, treating excessive cold in the Foot-Taiyin Spleen Meridian, guiding it back to the Yangming Stomach. When these two meridians are harmonized, there will be no conflict between Yin and Yang; thus, they serve as the Sovereign (Jun) herbs. *Chang Shan* (*Dichroa Radix*, 常山) treats alternating chills and fever in malaria and expels phlegm accumulation in the chest, serving as the Minister (Chen) herb. *Gan Cao* (*Glycyrrhizae Radix et Rhizoma*, 甘草) harmonizes the various herbs; *Wu Mei* (*Mume Fructus*, 乌梅) astringes, generates fluids, and reduces fever; *Bei Mu* (*Fritillariae Bulbus*, 贝母) resolves phlegm, eliminates nodules, and disperses stagnation; *Bing Lang* (*Arecae Semen*, 槟榔) removes phlegm-stasis and breaks qi stagnation; these serve as the Assistant (Zuo) herbs. *Chuanshan Jia* (*Manis Squama*, 穿山甲) lives in mountains but enters water, capable of moving between Yin and Yang, penetrating collaterals to enter the Ying (Nutrient) level, thereby breaking the binding of summerheat pathogens; it serves as the Envoy (Shi) herb. This formula is effective only for patients with stagnant phlegm in the Spleen and Stomach.
