Pediatric food-stagnation malaria is caused by irregular dieting in daily life combined with exposure to wind-heat pathogens, resulting in alternating chills and fever, chest and abdominal distension, stuffiness and obstruction, sallow complexion, and anorexia. Treatment varies according to the severity of food stagnation: for mild cases, the ancient method prescribes Chai Ping Tang (Bupleurum and Pinellia Decoction), containing Chenpi (Citri Reticulatae Pericarpium), Jiangzhi Banxia (Pinelliae Rhizoma Preparatum cum Zingibere), Cangzhu (Atractylodis Rhizoma) stir-fried after soaking in rice wash water, Jiangchao Houpo (Magnoliae Officinalis Cortex) stir-fried with ginger, Huangqin (Scutellariae Radix), Chaihu (Bupleuri Radix), Gancao (Glycyrrhizae Radix et Rhizoma), Renshen (Ginseng Radix et Rhizoma), with Shengjiang (Zingiberis Rhizoma Recens) and Dazao (Jujubae Fructus) as guides. For severe cases, the ancient method prescribes Da Chai Hu Tang (Major Bupleurum Decoction), containing Chaihu (Bupleuri Radix), Huangqin (Scutellariae Radix), Chishao (Paeoniae Radix Rubra), Jiangzhi Banxia (Pinelliae Rhizoma Preparatum cum Zingibere), Fuchao Zhishi (Aurantii Fructus Immaturus) stir-fried with bran, Dahuang (Rhei Radix et Rhizoma), with Shengjiang (Zingiberis Rhizoma Recens) and Dazao (Jujubae Fructus) as guides, plus Binglang (Arecae Semen) and Caoguo (Tsaoko Fructus).
[Commentary by Chen Shouzhen] Food-stagnation malaria is also known as Phlegm-malaria. Any condition where damage from consuming raw/cold foods, fish/meat, or greasy substances leads to phlegm retention in the middle jiao (epigastrium) constitutes food-stagnation malaria. Since this arises from food stagnation generating phlegm, Renshen (Ginseng Radix et Rhizoma) should not be used. The prescription consists of Guang Juhong (Citri Reticulatae Pericarpium) 1.5 qian, Faxia Banxia (Pinelliae Rhizoma Preparatum) 1 qian, You Houpo (Magnoliae Officinalis Cortex) 8 fen, Chao Zhishi (Aurantii Fructus Immaturus) 8 fen, Chao Baizhu (Atractylodis Macrocephalae Rhizoma) 1 qian, Bai Fuling (Poria) 2 qian, Peng E Zhu (Curcumae Rhizoma) 1.5 qian, Xiao Qingpi (Citri Reticulatae Pericarpium Viride) 5 fen, with Shengjiang (Zingiberis Rhizoma Recens) 2 slices as a guide.
If phlegm dissipates and malaria symptoms subside, add Chao Dangshen (Codonopsis Radix) 1.5 qian to the original formula and continue administration.
Children with pre-existing fluid retention (yin) who contract external pathogens causing stagnation in the spleen and stomach may present with vomiting and regurgitation. If malaria persists after sweating or purging therapies, with no exterior or interior syndromes remaining, the ancient method prescribes Qing Pi Yin (Clear the Spleen Decoction), containing Chaihu (Bupleuri Radix), Huangqin (Scutellariae Radix), Jiang Banxia (Pinelliae Rhizoma Preparatum cum Zingibere), Zhigancao (Glycyrrhizae Radix et Rhizoma Preparatum cum Melle), Houpo (Magnoliae Officinalis Cortex), Qingpi (Citri Reticulatae Pericarpium Viride), Binglang (Arecae Semen), Fuling (Poria), Caoguo (Tsaoko Fructus), Renshen (Ginseng Radix et Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma), Juhong (Citri Reticulatae Pericarpium), Cangzhu (Atractylodis Rhizoma), with Shengjiang (Zingiberis Rhizoma Recens) as a guide.
[Commentary by Chen Shouzhen] For post-malaria fluid retention, Chaihu (Bupleuri Radix) and Huangqin (Scutellariae Radix) are unnecessary. The prescription consists of Huazhou Juhong (Citri Reticulatae Pericarpium from Huazhou) 1.5 qian, Jiangzhi Banxia (Pinelliae Rhizoma Preparatum cum Zingibere) 1 qian, Cuqiao Qingpi (Citri Reticulatae Pericarpium Viride vinegar-fried) 5 fen, Caoguoren (Tsaokos Fructus Seed) 5 fen, Tuchao Baizhu (Atractylodis Macrocephalae Rhizoma soil-fried) 1.5 qian, You Houpo (Magnoliae Officinalis Cortex) 8 fen, Yun Fuling (Poria) 3 qian, Zhigancao (Glycyrrhizae Radix et Rhizoma Preparatum cum Melle) 5 fen, without guides.
For excessive phlegm, add Zhidanxing (Arisaematis Cum Bile Rhizoma) 3 fen; for excessive fluid retention, add Cangzhu (Atractylodis Rhizoma) soaked in rice wash water and fried 5 fen; for weak constitution, add Chao Dangshen (Codonopsis Radix) 1.5 qian.
