A kind of malaria described in A Unified Treatise on Diseases, Patterns, and Remedies According to the Three Causes (三因极一病症方论 sān yīn jí yī bìng zhèng fāng lùn) as follows: When the patient has [alternating aversion to] cold and heat [effusion], rapid hungering and inability to eat, propping fullness after eating, and tense painful abdomen, occurring at day intervals, this is called stomach malaria. When none of the six bowels except the stomach has malaria, this is commonly called food malaria. Other forms of malaria with dietary irregularities can mutate into this pattern.
Zhāng’s Clear View of Medicine (张氏医通 zhāng shì yī tōng, nüè) states, Food malaria is attributable to dietary irregularities that engender phlegm in the center stomach duct, which is exacerbated by wind qì; hence there is rapid hungering and inability to eat, and propping fullness after eating, enlarged abdomen, and frequent retching. Repletion is treated by Two Matured Ingredients Decoction (二陈汤èr chén tāng) plus bitter orange (Aurantii Fructus, 枳壳zhǐ ké) and tsaoko (Tsaoko Fructus, 草果cǎo guǒ). When it is due to irregular eating or excessive physical exertion, persists for a long timeand is associated with a vacuous pulse, use Center-Rectifying Decoction (理中汤lǐ zhōng tāng) plus unripe bitter orange (Aurantii Fructus Immaturus, 枳实zhǐ shí) and unripe tangerine peel (Citri Reticulatae Pericarpium Viride, 青皮qīng pí). When the patient ordinarily suffers from yīn vacuity taxation, or when malaria has turned into taxation, then the formula should contain cinnamon twig (Cinnamomi Ramulus, 桂枝guì zhī), ginger (Zingiberis Rhizoma, 姜jiāng), and jujube (Jujubae Fructus, 大枣dà zǎo); wind-dispelling phlegm-sweeping medicinals cannot be used alone. If the exterior evil is exuberant, Minor Center-Fortifying Decoction (小建中汤xiǎo jiàn zhōng tāng) or Astragalus Center-Fortifying Decoction (黄芪建中汤huáng qí jiàn zhōng tāng) can be used as the main treatment, followed by Six-Ingredient Pill (六味丸liù wèi wán), with all ingredients used raw, plus cinnamon twig (Cinnamomi Ramulus, 桂枝guì zhī) and turtle shell (Trionycis Carapax, 鳖甲biē jiǎ).
