When malaria persists for years without cure, it is called Lao Malaria (Chronic/Malnutrition-induced Malaria), and this formula should be used as the primary treatment.
The character "Lao" means old or chronic. When the disease persists for years without resolution, both Qi and Blood become deficient, and the malaria pathogen penetrates deeply into the interior. For Qi deficiency, Ren Shen, Huang Qi, Bai Zhu, and Gan Cao are used to tonify Qi; for Blood deficiency, Dang Gui is used to nourish Blood; for the deep-seated malaria pathogen, Chai Hu and Sheng Ma are used to raise and lift Yang Qi, allowing the pathogenic factor to gradually emerge to the exterior. The formula contains Chen Pi, which can resolve phlegm and drain Qi, assisting Chai Hu and Sheng Ma in achieving success. If the malaria attacks at night, according to Danxi, it has entered the Yin aspect and Blood aspect. In this case, it is appropriate to double the dosage of Dang Gui in this formula, or to combine it with Si Wu Tang (Four Substance Decoction). For the main examination, refer to the Spleen and Stomach section; for cross-reference, see the Deficiency and Damage section.

When malaria occurs, accompanied by an inability to bear even slight exertion, persisting for years without recovery, and recurring repeatedly, it is called Lao Malaria, and this formula is indicated.
Daily labor places demands on sinews and strength. Sinews belong to the Liver, and the Shaoyang Gallbladder is its associated Fu organ. The formula contains Chai Hu and Huang Qin, which can clear Shaoyang pathogenic heat; Gua Lou Gen can generate fluids and nourish sinews; Ren Shen and Gan Cao can tonify deficiency and dispel fatigue; Da Zao and Sheng Jiang can harmonize Ying and Wei and benefit the Stomach. It is also said: Ren Shen, Gan Cao, Sheng Jiang, and Da Zao are herbs for regulating the Stomach house. Only the Stomach can effectively influence the Liver and distribute Qi to the sinews; therefore, this formula is used to regulate Lao Malaria.

When malaria attacks, causing pain throughout the entire body, heaviness in the hands and feet, more chills than fever, and a soggy pulse, it is called Shi Malaria (Dampness-type Malaria), and this formula is indicated.
The aforementioned symptoms are all manifestations of Dampness patterns. Therefore, Xiao Chai Hu Tang (Minor Bupleurum Decoction) is used to harmonize the exterior and interior, and Ping Wei San (Powder for Peaceful Stomach) is used to strengthen the Spleen and control Dampness. Combining these two formulas into one gives it the name Chai Ping Tang. For the main examination of Xiao Chai Hu Tang, refer to the Cold Damage section; for the main examination of Ping Wei San, refer to the Dampness section.
