When Summerheat-Turbidity (Shuyu) develops into Malaria, it occurs once daily. If the interval extends to one day later, the onset time is delayed by one shichen (two hours). The twelve meridians circulate without rest; this condition is named "Ghost Malaria" (Guinie). It is appropriate to use Guizhi Tang (Cinnamon Twig Decoction) combined with Chaihu Tang (Bupleurum Decoction), adding Longgu (Fossilized Bones) and Muli (Oyster Shell) to support the healthy Qi and expel the pathogenic factor.

This passage describes malaria where the onset is delayed by one shichen after a day's interval, cycling continuously without respite. This indicates that the pathogen resides not in the Zang-Fu organs but in the meridians; thus, its manifestation follows the circulation of Ying and Wei Qi, flowing unceasingly. It is called "Ghost Malaria" because the delay of one shichen each day is precise, as if possessed by a spirit. Therefore, Guizhi Tang combined with Chaihu Tang should be used to protect Yang Qi and vent the pathogen, while simultaneously employing Longgu and Muli to calm the Spirit and expel the pathogen, preventing the pathogen from becoming excessive and the healthy Qi from becoming deficient, which would lead to a protracted course.

Summerheat-Turbidity Malaria occurring at intervals of two days, with variable onset times (early or late), swelling at the wrist, wiry pulse, pale tongue, and loose stools, constitutes Taiyin Malaria. It is appropriate to use Qingpi Yin (Spleen-Clearing Drink) added with Biejia (Turtle Shell), Qinghao (Sweet Wormwood Herb), and Shenqu (Medicated Leaven). This formula warms the Spleen and regulates the pathogen.

Whenever Malaria pathogens arrive, they must enter from the extremities to disturb the Central Palace (Spleen and Stomach). Although the fever occurs at intervals, the presence of wrist swelling, wiry pulse, pale tongue, and loose stools indicates severe damage to Spleen Yang, with Liver Wood overacting on Earth, potentially progressing to edema and distension. Therefore, Baizhu (Atractylodis Macrocephalae Rhizoma), Houpo (Magnoliae Officinalis Cortex), Banxia (Pinelliae Rhizoma), Fuling (Poria), Chenpi (Citri Reticulatae Pericarpium), Shenqu (Massa Medicata Fermentata), and Caoguo (Tsao-ko Fruit) are used to warm the Taiyin, while Chaihu (Bupleuri Radix), Qingpi (Aurantii Fructus Viridis), and Biejia are used to clear the Jueyin.

Summerheat-Turbidity Malaria occurring every three days, or manifesting near midnight, with sallow complexion, reduced appetite, abdominal distension, loose stools, and a wiry pulse, constitutes Jueyin Malaria. It is appropriate to use Wu Youke's Sanjia San (Three-Shells Powder) combined with Qingpi Yin to regulate the Spleen and soothe the Liver.

Malaria having established a three-day cycle, coinciding with the evening hours, indicates that the pathogen is latent within the Three Yin meridians, lying deepest. Although it primarily affects the Liver pathogen, prolonged duration inevitably injures the Spleen. Manifestations such as sallow complexion, anorexia, abdominal distension, and loose stools indicate that the Spleen is being overcome by its uncongenial element (Liver Wood), resulting in injury to the Healthy Qi. If the Spleen is not supported, abdominal distension and fullness will surely ensue. Thus, Qingpi Yin is used to regulate the Spleen and soothe the Liver, combined with Wu Shi's Sanjia San to search out and eliminate latent pathogens. Consequently, the Spleen Yuan gradually recovers, the Liver pathogen gradually dissipates, and the malaria ceases spontaneously.
