(Qi Level, Blood Level)
[Symptoms of Fever at the Qi Level] The patient is quiet at night but experiences irritability and fever during the day; lips are scorched and dry with thirst, drinking much fluid accompanied by sweating. These are symptoms of fever at the Qi level.
[Note: Original text appears to have a gap or formatting error here. Based on context "This is the cause of internal injury excess heat", it likely refers to etiology, but per instructions, no content is added.] This is the cause of excess heat due to internal injury. If the primordial essence is insufficient, with deficient Qi and scattered spirit, feeling cool at night and hot during the day, this is the cause of deficiency heat due to internal injury.
[Pulse of Fever at the Qi Level] A rapid pulse at the left Cun position indicates Heat in Heart Qi. A rapid pulse at the left Guan position indicates Heat in Liver and Gallbladder. A rapid pulse at the right Cun position indicates Heat in Large Intestine and Lung.
[Treatment for Fever at the Qi Level] A surging and rapid pulse on the left side indicates fever at the Qi level of Liver and Gallbladder; treat with Qianghuo Chaihu Tang (Notopterygium and Bupleurum Decoction) or Digupi San (Lycium Bark Powder). A surging and rapid pulse on the right side indicates Heat in Qi of Stomach and Intestines; treat with Gange Shigao Tang (Pueraria and Gypsum Decoction) or Jiegeng Tang (Platycodon Decoction).

[Symptoms of Fever at the Blood Level] The patient is quiet during the day but experiences fever at night; lips are scorched and dry with mouth thirst, yet there is no desire to drink; spontaneous sweating occurs during sleep. These are symptoms of fever at the Blood level.
[Causes of Fever at the Blood Level] It may be due to heat lingering in the blood after a febrile disease; or due to chronic deficiency of Yin-Blood leading to hyperactive Fire from Blood deficiency; both conditions result in fever at the Blood level.
[Pulse of Fever at the Blood Level] A rapid pulse at the left Cun position indicates Blood Heat in the Heart Meridian. A rapid pulse at the left Guan position indicates Blood Heat in the Liver and Gallbladder. A rapid pulse at the right Cun position indicates Heat in Large Intestine and Lung.
[Treatment for Fever at the Blood Level] For Blood Heat in the Heart Meridian: Excess Heat, use Daochi Geban Tang (Half-and-Half Daochi Decoction); Deficiency Heat, use Tianwang Buxin Dan (Emperor of Heaven's Tonification of the Heart Pill). For Blood Heat in the Liver Meridian: Excess [Heat], use Zhilian Siwu Tang (Gardenia and Coptis Four Substances Decoction); Deficiency Heat, use Guishao Chaihu Tang (Angelica and White Peony Bupleurum Decoction). A surging and rapid pulse on the right side indicates Blood Heat in Lung, Stomach, and Large Intestine: Excess Heat, use Qingwei Tang (Clear Stomach Decoction); Deficiency Heat, use Xi[Jiao Dihuang Tang] (Rhinoceros Horn and Rehmannia Decoction).
Commentary by Zhen: For fever occurring at night, if there are no symptoms such as initial chills followed by fever, one may treat it as Blood Heat; however, if there are initial chills followed by fever every night, this is a exterior pathogenic factor resembling malaria in the Taiyang Meridian, and should be treated with exterior-releasing medicines such as Qianghuo Tang from the Taiyang Meridian.

The above four formulas are the orthodox methods for treating internal injury fever according to family secrets. In the formula for Deficient Blood Fever, Ginseng [and Astragalus] are added because Qi has the function of generating Blood; in the formula for Deficient Qi Fever, no blood-tonifying herbs are added because Blood does not have the principle of benefiting Qi.
