Quan Sheng Zhi Mi (Guide to the Mystery of Complete Life) states: Diseases involving alternating cold and heat may present as cold followed by heat, or heat followed by cold. If accompanied by chills and tremors, severe headache as if splitting, bodily stiffness and tightness, frequent yawning, and thirst with a desire to drink cold fluids, it indicates a specific pattern. Whether the cold precedes the heat, or the heat precedes the cold; whether it occurs at fixed intervals or every other day, manifesting precisely at the appointed time and resolving to normalcy afterward, this is termed Malaria (Nue). The pulse in Malaria is naturally Xian (String-like); a Shu (Rapid) pulse indicates excess Heat, while a Chi (Slow) pulse indicates excess Cold. These conditions arise from Wind-Cold pathogens contracted in winter, which hide within the Marrow. When Yang Qi flourishes in spring, the pathogenic factor cannot exit spontaneously. Upon encountering intense summer heat, it combines with the pathogen to manifest. For cases with more Heat, resolution via diaphoresis is appropriate, using Changshan Tang (Dichroa Decoction) or Gualou Tang (Trichosanthes Root Decoction). (Prescriptions follow below.)
Quan Sheng Zhi Mi Changshan Tang (Dichroa Decoction)
Changshan (Dichroae Radix), Zhimu (Anemarrhenae Rhizoma), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried, each 3 liang), Mahuang (Ephedrae Herba, nodes removed, 1 liang).
Grind into coarse powder. Take 5 qian per dose, add 2 zhan of water, decoct until 1 zhan remains, strain, and take warm. Drink one cup of millet porridge to assist sweating.
Quan Sheng Zhi Mi Gualou Tang (Trichosanthes Root Decoction)
Gualougen (Trichosanthis Radix, 4 liang), Chaihu (Bupleuri Radix, remove seedlings, 8 liang), Renshen (Ginseng Radix), Huangqin (Scutellariae Radix), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried, each 3 liang).
Grind into coarse powder. Take 5 qian per dose, add 2 zhan of water, 3 slices of fresh ginger, and one broken jujube. Decoct until 1 zhan remains, strain, and take warm.

These conditions arise from Wind-Cold pathogens contracted in winter, where Cold Qi hides within the Marrow. When Yang Qi flourishes in spring, the pathogenic factor cannot exit spontaneously. Upon encountering intense summer heat, it combines with the pathogen to manifest. For cases with more Cold, warming therapy is appropriate, using Jianggui Tang (Ginger and Cinnamon Decoction). (Prescription follows below.)
Quan Sheng Zhi Mi Jianggui Tang (Ginger and Cinnamon Decoction)
Ganjiang (Zingiberis Rhizoma), Muli (Ostreae Concha, calcined until red-hot), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried, each 2 liang), Guizhi (Cinnamomi Ramulus, bark removed, heartwood taken, 3 liang), Chaihu (Bupleuri Radix, 8 liang, remove seedlings), Gualougen (Trichosanthis Radix, 4 liang), Huangqin (Scutellariae Radix, 2 liang, wine-fried completely, use 3 liang).
Grind into coarse powder. Take 5 qian per dose, add 2 zhan of water, decoct until 1 zhan remains, strain, and take warm. Time of administration is not restricted.
Huoren Shu (Book of Vitality) treats Malaria with a floating and large pulse, alternating cold and heat, using emesis. Books from Weizhou state that Malaria with more cold than heat is due to excessive Phlegm. However, if there is more cold than heat and a floating pulse, Phlegm is undoubtedly the cause, and emesis is indicated. If the pulse is slow and faint, it is merely Malaria with aversion to cold, suitable for treatment with Chaihu, Guizhi, and Ganjiang. Quxie Wan (Evil-Expelling Pill) Prescription
Mahuang (Ephedrae Herba, 4 liang, nodes removed, soaked in boiling water for one or two boils, dried by roasting, weighed), Changshan (Dichroae Radix), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried), Dahuang (Rhei Radix et Rhizoma), Zhimu (Anemarrhenae Rhizoma, each 3 liang).
Pound, sieve into fine powder, and refine honey to form pills the size of white mustard seeds. Take 15 pills per dose. Face east and swallow with clear water. (Compared to Changshan Wan in Qianjin Fang under the section "Cold Preceding Heat," the ingredients are the same but dosages differ.)
