《全生指迷》论曰∶寒热之病，或寒已而热，或热已而寒。若寒热战栗，头痛如破，身体拘急，数欠、渴欲
饮冷。或先寒而后热，或先热而后寒，或 时而发，或间日而作，至其时便发，已即如常，此谓之疟。疟脉自
弦，弦数多热，弦迟多寒。此皆得之于冬中风寒之气，寒气藏于骨髓之中，至春阳气大发，邪气不能自出，因
遇大暑，而后与邪气相合而发。寒热等者，宜调之，与鳖甲汤。（方在门中。）

Quan Sheng Zhi Mi (Guide to Understanding Complete Life) states: In diseases characterized by alternating cold and heat, sometimes the cold subsides followed by heat, or the heat subsides followed by cold. If there are symptoms such as chills and trembling, severe headache as if the head were bursting, bodily stiffness and urgency, frequent yawning, thirst with a desire to drink cold fluids, or if one feels cold first then hot, or hot first then cold, or if it occurs at regular intervals, or every other day, occurring precisely at its appointed time and resolving to normalcy afterwards, this is termed Malaria (Nue). The pulse of Malaria is naturally wiry (Xian). A wiry and rapid pulse indicates excess heat, while a wiry and slow pulse indicates excess cold. These conditions arise from contracting wind-cold pathogens in winter; the cold qi hides within the bone marrow. When spring arrives and yang qi expands vigorously, the pathogenic qi cannot expel itself. Upon encountering intense summer heat, it combines with the pathogenic qi and manifests. For cases where cold and heat are equal, regulation is appropriate using Biejia Tang (Bie Jia Tang, Turtle Shell Decoction). (The formula is found within this section.)
Taiping Shenghui Fang (Imperial Grace Formulas of the Taiping Era) treats pediatric malaria with alternating chills and fever and body tremors. Huangdan Wan Formula:
Huang Dan (Lead Oxide, lightly stir-fried) Chang Shan (Dichroa Root, powdered. Each half liang) Hu Jing (Tiger Eye, soaked in wine, roasted until yellow)
Grind the above ingredients together into a fine powder. Mix with refined honey to form pills the size of paulownia seeds. Before the onset of an attack, administer two pills with warm water. Children under five years old may take one pill.
Taiping Shenghui Fang treats pediatric malaria presenting with high fever during attacks, increased aversion to cold, greenish-yellow complexion, and inability to eat. Changshan Wan Formula:
Chang Shan (Dichroa Root) Chuan Da Huang (Rhubarb Radix, crushed, lightly stir-fried) Gan Cao (Licorice Root, roasted until slightly red, crushed. Each half liang) She Xiang (Musk, half qian, finely ground)
Pulverize the above ingredients, sieve them, and mix thoroughly with the ground Musk. Use refined honey to form pills the size of paulownia seeds. Just before the onset of an attack, administer two pills with warm water. Children under three years old take one pill.
Taiping Shenghui Fang, another formula:
Burn snake skin to ash, grind finely into a powder. Before the onset of an attack, mix with cold water and administer a dose of "yi zi" (a traditional small measure). Children over two years old take half a qian.
Taiping Shenghui Fang, another formula (Identical to the Qianjin Formula for malaria with heat preceding cold found in that section. Both types of malaria can use this, so both are recorded.)
Take one liang of Bie Jia (Turtle Shell), burn to ash, and grind finely into a powder. Before the onset of an attack, mix with warm wine and administer half a qian. Children under three years old take a dose of "yi zi".
Zhang Huan treats malaria with Tao Ren Tang Formula:
Tao Ren (Peach Kernel, soaked in hot water, peel and tip removed, double-kernel removed, stir-fried with bran until yellow) Bie Jia (Turtle Shell, roasted with butter until slightly yellow, remove skirt edges. Each one liang) Gui Xin (Cinnamon Heart) Huang Qin (Scutellaria Root) Chi Fu Ling (Red Poria) Chuan Sheng Ma (Cimicifuga Rhizome. Each half liang)
Pulverize the above ingredients into a coarse powder. For each dose, take one qian, add one small cup of water, decoct until only half a cup remains, strain, and take warm. Adjust dosage according to the child's age and size.
Quan Sheng Zhi Mi, Biejia Tang:
Bie Jia (Turtle Shell, soaked in hot water, scraped clean, roasted with vinegar) Bai Zhu (Atractylodes Macrocephala Rhizome) Chang Shan (Dichroa Root) Gui (Cinnamon Bark, peeled) Chai Hu (Bupleurum Root, stems removed. Each one liang) Mu Li (Oyster Shell, half liang, calcined until red)
Process the above into a coarse powder. For each dose, take five qian, add two cups of water, decoct until one cup remains, strain, and take warm.
