Pediatric cough that persists without improvement may be treated with moxibustion on Feishu (BL13, Lung Shu). (This acupoint is located on the back, one cun five fen lateral to the midline, below the third thoracic vertebra.)

The *Classic of Internal Medicine* states: "If summerheat is injured in summer, malaria will inevitably occur in autumn." Those who are lightly injured manifest symptoms quickly and abruptly; those heavily injured lie dormant for a longer period before developing into chronic malaria. Thus, it is understood that summerheat injury causes Qi obstruction, preventing external release, allowing pathogenic factors to move inward, which manifests as malaria in autumn. This often arises because caregivers hold infants improperly, failing to shield them from wind-cold; additionally, exposure to summer heat and warm pathogens allows evil qi to lodge in the skin and accumulate in the zang-fu organs. This leads to an imbalance of Yin and Yang, where pathogenic factors attack healthy Qi, resulting in alternating chills and fever. Excess Yang results in heat; excess Yin results in cold. Chills preceding fever indicate insufficient Yang; fever preceding chills indicates insufficient Yin. More chills than heat indicates Yin prevailing over Yang; more heat than chills indicates Yang prevailing over Yin. Equal amounts of chills and heat indicate mutual conflict between Yin and Yang; alternating chills and heat indicate intermittent separation of Yin and Yang. Generally, pediatric cases arise frequently from dietary issues. One must first employ methods to resolve stagnation and guide food out, then regulate according to the specific cause of the disease; this is the superior method.

The *Essential Prescriptions of the Golden Cabinet* states: "The pulse of malaria is naturally wiry. A wiry and rapid pulse indicates much heat; a wiry and slow pulse indicates much cold. If wiry, small, and tight, purgation may be used; if wiry and slow, warming is appropriate; if wiry and tight, sweating may be induced; if floating and large, emesis may be employed. A wiry and rapid pulse indicates wind-heat, which can be resolved through dietary management."

*Illustrated Miscellaneous Works of a Clear Physician* states: Malaria is caused by wind and summerheat pathogens. It may occur once daily, every two days, or every three days; sometimes it occurs for two consecutive days after skipping one day; it may occur both day and night; it may present with or without sweating; it may occur in the morning or afternoon; or at night. Treatment principles dictate that since the pathogen enters from the exterior, dispersing methods should be used, but supporting Stomach Qi is fundamental. Medication must also be differentiated based on whether the condition involves the Yang aspect or the Yin aspect. For excess malaria and acute attacks, dispersing or intercepting methods are suitable; for deficiency malaria and chronic cases, tonifying Qi and Blood is indicated. Overuse of intercepting medicines damages the Spleen and Stomach, causing the disease to linger indefinitely. For cases with much heat and little cold without sweating, Guizhi Mahuang Ban Tang (Half-Green Twig and Half-Ephedra Decoction) is used; for cases with profuse sweating, Chaihu Guizhi Tang (Bupleurum and Green Twig Decoction) is used; for cases with profuse sweating and thirst, Baitao Jia Guizhi Tang (White Tiger plus Green Twig Decoction) is used; for cases with dark urine, much heat and little cold, Xiaochaihu Tang (Minor Bupleurum Decoction) is used; for cases with much cold and little heat, Qingpi Yangwei Tang (Clear Spleen and Nourish Stomach Decoction) is used; for chronic cases not resolving, Gui Ku San (Ghost Cry Powder) is used to intercept. For cases with much heat, profuse sweating like diarrhea, and abdominal pain, Daxiehu Tang (Major Bupleurum Decoction) is used to purge; for chronic malaria not healing with intestinal masses, Muxiang Wan (Aucklandia Pill) and Biejia Yinzi (Softshell Turtle Drink) are used for regulation; for severe cases, Shen Xiao Wan (Divine Effect Pill) is used to eliminate; for irritability and thirst, Wuling San (Five Ingredient Powder with Poria) is used. Some children develop edema, enlarged external genitalia, or dietary damage to the Spleen and Stomach due to using antipyretics too early in malaria treatment. Edema is an external manifestation of the Spleen; Dadou Pi Tang (Areca Peel Decoction) and Caoguo Yin (Tsaoko Drink) are appropriate.
