凡是小儿触犯冒受风、寒、暑、湿邪气，邪气客居于皮肤，积聚于脏腑，邪气与正气相互攻伐，导致阴阳偏盛，发作时出现寒热往来。阳气不足则先恶寒后发热，阴气不足则先发热后恶寒。寒多热少的，是阴胜阳衰；热多寒少的，是阳胜阴衰。阴阳互相攻伐，则寒热程度相等。其初起时，必然内有痰饮和食积，导致脏气运行不畅，因此发作成为疟疾（一种以寒战、高热、头痛、汗出为特征的疾病）。
风疟（由风邪引起的疟疾）因感受风邪而得，症状为怕风、自汗、烦躁口渴、头痛不安，属于风疟，所以先发热后恶寒。初起服用桂枝汤（调和营卫的方剂），若不退热，再服用柴胡汤（和解少阳的方剂）加常山、槟榔、乌梅来截断疟疾。久治不退的，多服补中益气汤（补中益气、升阳举陷的方剂）可自愈。
寒疟（由寒邪引起的疟疾）因感受寒邪而得，症状为无汗、怕冷、肢体拘挛紧急、面色青白，属阴证。所以先恶寒后发热，宜发散寒邪，用养胃汤加桂心，若不退，再服用平胃散（燥湿运脾的方剂）加槟榔、草果来截断疟疾。久治不退，用六君子汤（益气健脾、燥湿化痰的方剂）加干姜、肉桂，服用后可自愈。
暑疟（由暑邪引起的疟疾）因损伤暑之阴气而发，发作时只发热不恶寒，烦躁口渴、睡眠少、呕吐恶心。宜解暑毒，用柴胡白虎汤（清热生津的方剂）。若不止，去掉石膏，加贝母、常山、槟榔来截断疟疾。久治不退，服用补中益气汤可自愈。
湿疟（由湿邪引起的疟疾）因冒雨或久坐湿地而得，症状为身体肢节乏力、呕吐逆气、腹胀满。初起服用胃苓汤（利水渗湿的方剂）若不止，再服用平胃散加茯苓、槟榔、常山来截断疟疾。久治不止者，服用参苓白术散（益气健脾、渗湿止泻的方剂）可自愈。
食疟（由饮食不当引起的疟疾）是由于饮食不节制，饥饱失调所致。凡是食用生冷、鱼肉、油腻之物，导致中脘停聚痰饮，都称为食疟。其症状为饥饿但不想进食，胸中胀满、呕吐逆气、腹痛，宜消食导滞。初起服用四兽饮（化痰截疟的方剂），若不止，再服用二陈汤（燥湿化痰的方剂）加枳壳、胡椒、白芷来截断疟疾。久治不愈，用六君子汤，根据食积和气体的虚实进行加减，服用后可自愈。

Whenever a child is exposed to wind, cold, summerheat, and dampness pathogens, the pathogens lodge in the skin and accumulate in the zang-fu organs. The pathogenic factors attack the righteous qi, leading to an excess of either yin or yang. Upon onset, there is alternating chills and fever. If yang is insufficient, chills precede fever; if yin is insufficient, fever precedes chills. When chills are more severe than fever, it indicates yin excess over yang; when fever is more severe than chills, it indicates yang excess over yin. When yin and yang attack each other mutually, the chills and fever are equal in degree. Initially, there must be internal phlegm and food retention, causing the qi of the zang-fu organs to stagnate, thus manifesting as malaria (a disease characterized by chills, high fever, headache, and sweating).
Wind malaria arises from wind pathogen invasion. Symptoms include aversion to wind, spontaneous sweating, irritability, thirst, headache, and restlessness. This is wind malaria, so fever precedes chills. Initially, administer Guizhi Tang (Cinnamon Twig Decoction). If symptoms do not subside, administer Chaihu Tang (Bupleurum Decoction) with Changshan (Dichroae Radix), Binglang (Arecae Semen), and Wumei (Mume Fructus) to arrest the malaria. For chronic cases that do not resolve, frequent administration of Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) will lead to self-healing.
Cold malaria arises from cold pathogen invasion. Symptoms include absence of sweating, aversion to cold, muscle spasms and stiffness, and a cyan complexion, indicating a yin pattern. Thus, chills precede fever. It is appropriate to disperse cold pathogens using Yangwei Tang (Stomach-Nourishing Decoction) with Guixin (Cinnamomi Cortex). If symptoms do not subside, administer Pingwei San (Peaceful Stomach Powder) with Binglang (Arecae Semen) and Caoguo (Tsaoko Fructus) to arrest the malaria. For chronic cases, Liu Junzi Tang (Six Gentlemen Decoction) with Ganjiang (Zingiberis Rhizoma) and Rougui (Cinnamomi Ramulus) should be administered for self-healing.
Summerheat malaria arises from damage to yin qi due to summerheat. Onset presents with fever without chills, irritability, thirst, insomnia, vomiting, and nausea. It is appropriate to resolve summerheat toxicity using Chaihu Baihu Tang (Bupleurum and White Tiger Decoction). If symptoms persist, remove Shigao (Gypsum Fibrosum) and add Beimu (Fritillariae Bulbus), Changshan (Dichroae Radix), and Binglang (Arecae Semen) to arrest the malaria. For chronic cases, Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) should be administered for self-healing.
Damp malaria arises from exposure to rain or prolonged sitting on damp ground. Symptoms include weakness in the body and limbs, regurgitation, abdominal distension, and fullness. Initially, administer Weiling Tang (Gastrointestinal and Lingzhi Decoction). If symptoms persist, administer Pingwei San (Peaceful Stomach Powder) with Fuling (Poria), Binglang (Arecae Semen), and Changshan (Dichroae Radix) to arrest the malaria. For chronic cases that do not resolve, Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) should be administered for self-healing.
Food malaria results from irregular diet and injury from hunger or overeating. Consumption of raw, cold, fish, meat, or greasy foods leads to phlegm retention in the Zhongwan (Middle Jiao), all classified as food malaria. Symptoms include hunger without desire to eat, epigastric fullness, vomiting and regurgitation, and abdominal pain. It is appropriate to eliminate food retention. Initially, administer Sishou Yin (Four Beasts Drink). If symptoms persist, administer Erchen Tang (Two Aged Ingredients Decoction) with Zhiqiao (Aurantii Fructus), Hujiao (Piperis Longi Fructus), and Baizhi (Angelicae Dahuricae Radix) to arrest the malaria. For chronic cases, Liu Junzi Tang (Six Gentlemen Decoction) should be used, modified according to the deficiency or excess of food retention and qi, leading to self-healing.
