Yin deficiency generates internal heat, while Yang excess generates external heat. Yin deficiency implies blood deficiency, which fails to maintain Yang, resulting in tidal fever with a fixed timing; Yang excess means pathogenic factors are abundant and lingering in the meridians, causing continuous fever without cessation. When pathogens transmit to the Gallbladder Fu-organ, alternating chills and fever occur; when pathogens sink into the Blood Chamber (Xueshi), fever occurs accompanied by delirious speech and mental confusion. When heat transmits to the Yangming channel, intense heat accumulates internally, leading to mental stupor and profuse sweating; although the external fever is tidal, delirious speech and mental confusion are particularly severe. When heat transmits to the Blood level, it stirs up the Jueyin Liver channel; although the tidal fever is mild, delirious speech is as severe as in Yangming disease, which is termed "heat entering the Blood Chamber." As for blood stasis or blood exhaustion, regardless of the presence or absence of pathogens, both can cause tidal fever in women.
A full and large pulse at the Chi position indicates Yang sinking into Yin; a large pulse at the Cun position with a weak Chi position indicates Yin deficiency and Yang excess. Blood deficiency presents with a deficient pulse; blood exhaustion presents with a choppy pulse; a choppy and large pulse indicates blood stasis; a full and rapid pulse indicates steaming heat.
Blood stasis should be treated by resolving and purging; blood deficiency should be treated by tonifying; blood heat should be cooled and resolved; blood exhaustion should be moistened and nourished.
For deficiency syndromes, Xiaoyao San (Free Wanderer Powder) is the primary formula; for excess syndromes, Longdan Xiegan Tang (Gentian Liver-Draining Decoction) is the primary formula. For pathogens in the Gallbladder aspect, Xiaochaihu Tang (Minor Bupleurum Decoction) is used with modifications according to symptoms. For pathogens sinking into the Blood Chamber, Xiaochaihu Tang is modified with Shengdi Huang (Rehmanniae Radix) and Mudan Pi (Moutan Cortex). For heat lurking in Yangming, Baihu Tang (White Tiger Decoction) is modified with Chai Hu (Bupleuri Radix) and Shengdi Huang. If heat is severe, Zhi Zi (Gardeniae Fructus), Mudan Pi, Chuan Xiong (Ligustici Chuanxiong Rhizoma), and Lian Qiao (Forsythiae Fructus - *Note: Text says 'Chuan, Lian', likely referring to Chuan Lian Zi or similar, but standard interpretation often links 'Lian' to Lian Qiao or Huang Lian. Given context of clearing heat, Huang Lian Coptidis Rhizoma is probable, but strictly following text 'Chuan, Lian'. Let's assume Chuan Xiong and Huang Lian based on common pairings in heat clearing, or simply transliterate if ambiguous. However, 'Chuan' usually refers to Chuan Xiong in blood formulas, but here it's heat. 'Lian' is likely Huang Lian. Let's use Chuan Xiong and Huang Lian as per common clinical practice for this specific modification pattern in ancient texts, or stick to literal. Actually, 'Chuan, Lian' in this context of heat often implies Chuan Lian Zi (Swietenia Semen) or Chuan Xiong + Huang Lian. Given 'Zhi, Dan, Chuan, Lian', it's likely Zhi Zi, Mu Dan Pi, Chuan Xiong, Huang Lian. I will translate as Chuan Xiong and Huang Lian.*) and Huang Lian (Coptidis Rhizoma). For heat entering the Blood Chamber, Siwu Tang (Four Substances Decoction) is modified with Chai Hu, Zhi Zi, and Mudan Pi.
**Xiaoyao San (Free Wanderer Powder)**
Treats tidal fever and irregular menstruation caused by blood deficiency, with a string-like and deficient pulse.
Ingredients: Chai Hu (Bupleuri Radix) (5 fen), Baishao (Paeoniae Radix Alba) (1.5 qian, stir-fried after scalding with boiling water), Gancao (Glycyrrhizae Radix et Rhizoma) (5 fen), Danggui (Angelicae Sinensis Radix) (2 qian), Baizhu (Atractylodis Macrocephalae Rhizoma) (1.5 qian, stir-fried), Fuling (Poria) (1.5 qian), Heye (Nelumbinis Folium) (3 qian).
Preparation: Decoct in water, remove dregs, and take warm.
Mechanism: Blood deficiency fails to maintain Yin, causing Yang to stagnate and fail to extend, thus tidal fever occurs with fixed timing, and menstruation is scanty and irregular. Danggui nourishes the blood vessels to enrich the Chong and Ren vessels; Baishao astringes Ying-Yin to harmonize the Liver and Spleen; Chai Hu disperses the interstices and resolves stagnation; Gancao harmonizes the Stomach and relieves urgency; Baizhu strengthens the Spleen Earth to generate blood; Fuling clears the governance nodes to harmonize the middle; adding Heye to raise Yang and harmonize the Stomach. Decoct in water and take warm. Ensure that menstrual blood fills internally, then deficient Yang retreats and hides, and tidal fever resolves naturally. Why worry about scanty menstruation and irregular cycles?
**Digupi San (Solomon's Seal Bark Powder)**
Treats blood and Qi deficiency with wind, intermittent chills and fever, scanty menstruation, with a string-like, deficient, and floating pulse.
Ingredients: Digupi (Cortici Lycii Radicis) (1 liang), Chai Hu (Bupleuri Radix) (5 qian), Sangbai Pi (Mori Cortex) (5 qian), Qian Hu (Peucedani Radix) (3 qian), Renshen (Ginseng Radix et Rhizoma) (6 qian), Huangqi (Astragali Radix) (1 liang, honey-fried), Wuqia (Acanthopanacis Cortex) (1 liang), Baishao (Paeoniae Radix Alba) (1 liang, stir-fried), Zhike (Aurantii Fructus Immaturus) (1 liang, stir-fried), Zhigancao (Prepared Glycyrrhizae Radix et Rhizoma) (1 liang), Guixin (Cinnamomi Ramulus) (5 qian), Fuling (Poria) (1 liang).
Preparation: Grind into powder. Take 3 qian, add 3 slices of fresh ginger, decoct in water, and take warm.
Mechanism: Blood and Qi deficiency with wind causes Ying and Wei Qi to be unvigorous, so chills and fever occur without fixed timing, and menstruation is scanty and obstructed. Renshen supports Yuan-Qi to unblock blood vessels; Huangqi tonifies Qi to benefit Wei-Yang; Qian Hu disperses wind and releases the exterior; Chai Hu opens the interstices to guide out pathogens; Baishao astringes Ying-Yin to support the Chong and Ren vessels; Guixin warms Ying-Blood to scatter external pathogens; Digupi clears the muscle layer and reduces fever; Sangbai Pi clears the Lung and descends Metal; Zhigancao moderates urgency, harmonizes the middle, and benefits the Stomach; Zhike transforms stagnation and widens the chest; Fuling clears the governance nodes; Wuqia regulates the meridians; fresh ginger warms Wei-Qi to scatter external pathogens. Decoct the powder and take warm. When Qi is sufficient and pathogens are resolved, Ying and Wei become harmonized, chills and fever resolve, and menstruation will not suffer from scarcity or obstruction.
**Chaihu San (Bupleurum Powder)**
Treats intermittent chills and fever, scanty menstruation, emaciation, pain in limbs and joints, with a rapid, string-like, floating, soft, and choppy pulse.
Ingredients: Chai Hu (Bupleuri Radix) (5 qian), Huangqi (Astragali Radix) (1 liang, honey-fried), Biejia (Testudinis Carapax et Plastrum) (2 liang, vinegar-fried), Baizhu (Atractylodis Macrocephalae Rhizoma) (1 liang, stir-fried), Maidong (Ophiopogonis Tuber) (1 liang, heart removed), Renshen (Ginseng Radix et Rhizoma) (1 liang), Shengdi Huang (Rehmanniae Radix) (3 liang), Chishao (Paeoniae Radix Rubra) (1 liang), Chiling (Poria with Red Host) (1 liang), Jiegeng (Platycodonis Radix) (5 qian), Zhike (Aurantii Fructus Immaturus) (5 qian, stir-fried), Gancao (Glycyrrhizae Radix et Rhizoma) (1 liang, stir-fried), Digupi (Cortici Lycii Radicis) (1 liang), Sangbai Pi (Mori Cortex) (1 liang).
Preparation: Grind into powder. Take 3 qian, add 1 slice of fresh ginger, decoct in water, remove dregs, and take.
Mechanism: Pathogens stagnate in the meridians and Fu-organs, persisting for a long time without resolution, combined with Qi deficiency and pathogen sinking, leading to chills and fever, scanty menstruation, emaciation, and pain in limbs and joints. The origin lies in overwork and excessive worry, damaging Qi and stagnating Blood, allowing pathogens to linger unresolved. Renshen supports Yuan-Qi and tonifies Qi; Huangqi tonifies the Middle and pushes pathogens out; Shengdi Huang nourishes Yin and generates Blood; Chishao breaks blood stasis and dissipates stagnation; Chai Hu opens the interstices to guide out pathogens; Baizhu strengthens Spleen Earth to strengthen the Stomach; Biejia nourishes Liver Yin and dissipates nodules; Maidong moistens the Lung and clears Heart Fire; Sangbai Pi clears Lung Qi; Digupi reduces muscle heat; Jiegeng clears the throat and benefits the diaphragm; Chiling leaches out dampness and harmonizes Ying; Zhike drains stagnant Qi to widen the chest; Gancao moderates the Central State to harmonize the Stomach; fresh ginger warms Wei-Qi and scatters external pathogens. Decoct 3 qian and take warm. When stagnation is dispersed and Qi is sufficient, pathogens are resolved externally, chills and fever are eliminated, limb and joint pains recede, and why worry about emaciation and scanty menstruation?
