Women may experience a continuous discharge of white matter throughout the year, resembling mucus or saliva, which cannot be controlled, and in severe cases, emits a foul odor; this is known as *Bai Dai* (White Leukorrhea). The leukorrhea disease belongs to dampness pathology. It is named "Dai" (Girdle Vessel) because women have a weakness in the Dai Mai (Girdle Vessel), failing to constrain fluids, hence the name. The Dai Mai connects with the Ren Mai (Conception Vessel) and Du Mai (Governor Vessel); when the Ren and Du vessels are diseased, the Dai Mai is also affected. The Dai Mai serves as the binding system for the fetus. Without this vessel, it is difficult to sustain pregnancy; thus, if the Dai Mai is weak, miscarriage is prone to occur, and if the Dai Mai is damaged, the fetus will certainly not be secure. However, damage to the Dai Mai is not solely due to falls, sprains, or contusions. Excessive sexual indulgence or drunken revelry, although causing no immediate pain, secretly depletes internal essence, leading to the spontaneous flow of white matter. Therefore, nuns, widows, and married women suffer from leukorrhea more frequently, while virgins living secluded lives are less affected. Nevertheless, virgin girls with congenital deficiency may also suffer from this condition. Furthermore, combined with Spleen Qi deficiency, Liver Qi stagnation, invasion of dampness, and pressure from fire, how could one not contract this syndrome? When dampness is excessive and fire is deficient, with Liver stagnation and Spleen deficiency, the Spleen Earth is injured. The Qi of damp-earth sinks downward, causing Spleen essence to fail to hold fast. Unable to transform into Ying Blood (Nutritive Blood), it becomes a white, slippery substance that flows directly from the Yin Gate (vagina), impossible to stop voluntarily. The treatment principle should be to greatly tonify Spleen and Stomach Qi, with a small addition of herbs that soothe stagnation, so that wind-water Qi does not block the earth, allowing earth Qi to naturally rise to heaven. When Spleen Qi is robust, dampness dissipates on its own. Use Wan Dai Tang (Complete Belt Decoction): Bai Zhu (Atractylodis Rhizoma, 1 liang), Cang Zhu (Atractylodis Rhizoma, 3 qian), Gan Cao (Glycyrrhizae Radix et Rhizoma, 1 qian), Che Qian Zi (Plantaginis Semen, 3 qian), Shan Yao (Dioscoreae Rhizoma, 1 liang), Chen Pi (Citri Reticulatae Pericarpium, 5 fen), Ren Shen (Ginseng Radix, 2 qian), Bai Shao (Paeoniae Radix Alba, 5 qian), Chai Hu (Bupleuri Radix, 6 fen), Jing Jie (Schizonepetae Herba, 5 fen), Ban Xia (Pinelliae Rhizoma, 1 qian). Decoct in water and take orally. Symptoms lighten after two doses, stop after four doses, and resolve completely after six doses.

This formula treats the Spleen, Stomach, and Liver meridians simultaneously. It embeds tonification within lifting and relies on dispersal for elimination. By opening the Qi of Liver Wood, Liver Blood will not become dry, preventing it from counter-attacking Spleen Earth. By tonifying the primal Qi of Spleen Earth, the Spleen Meridian will not be damp, making it easy to differentiate and eliminate water Qi. As for tonifying the Spleen while also tonifying the Stomach, it is because they are exterior-interior pairs; without strong Stomach Qi, the Spleen cannot flourish. Tonifying the Stomach is precisely to tonify the Spleen.

For this syndrome, Shu Dai Tang (Bind Belt Decoction) is also effective. Ji Guan Hua (Celosiae Cristatae Flos, 1 liang; fresh herb 3 liang) and Bai Zhu (Atractylodis Rhizoma, 1 liang). Decoct in water and take orally. Recovery occurs in two doses.

In women, leukorrhea may appear red, resembling blood but not being blood; this is called *Chi Dai* (Red Leukorrhea). Chi Dai is also a dampness disease caused by heat-fire. The Dai Mai is located between the waist and umbilicus, near the most Yin region, where fire should not exist. However, the Dai Mai connects to the Liver rather than the Kidney. Worry and thought injure the Spleen, and depression/anger injures the Liver, causing Liver Fire to blaze internally and counter-attack Spleen Earth. The Spleen Earth fails to transport and transform damp-heat Qi, which accumulates between the Dai Mai. Liver Fire burns, causing Liver Blood to fail to store itself, leaking into the Dai Mai. Due to Spleen Qi injury, the Dai Mai lacks constraining power. Damp-heat Qi sinks with the Qi flow, descending together with blood. Observing its appearance, it resembles blood but is not blood; in reality, blood and dampness are inseparable. People mistakenly attribute Chi Dai to Heart Fire. The treatment principle is to clear Liver Fire and support Spleen Qi, so that red leukorrhea may improve. Use Qing Gan Zhi Lin Tang (Clear Liver and Stop Dribbling Decoction): Shao Yao (Paeoniae Radix, 1 liang), Dang Gui (Angelicae Sinensis Radix, 1 liang), E Jiao (Colla Corii Asini, 3 qian), Sheng Di Huang (Rehmanniae Radix, 5 qian), Dan Pi (Moutan Cortex, 3 qian), Huang Bo (Phellodendri Cortex, 1 qian), Niu Xi (Achyranthis Bidentatae Radix, 2 qian), Hei Dou (Sojae Semen Nigrum, 1 liang), Xiang Fu (Cyperī Rhizoma, 1 qian), Hong Zao (Jujubae Fructus, 10 pieces). Decoct in water and take orally. Slight cessation after one dose, further cessation after two doses, complete cessation after four doses, no recurrence after ten doses.

This formula only tonifies Liver Blood and does not drain Spleen dampness because in Chi Dai, fire is heavy and dampness is light. Fire flares up due to Blood deficiency. Tonifying Blood suffices to control Fire. Moreover, since water and blood combine to form Chi Dai, distinguishing whether it is damp or not is futile; dampness has transformed into blood. Thus, treating blood is sufficient; why drain dampness? This formula purely treats blood with a slight addition of fire-clearing herbs, achieving unique efficacy. If one were to drain dampness, it would instead draw fire downward, making rapid recovery difficult. One might ask: previously, we said to assist Spleen Earth, but now we only tonify Liver Wood Blood, never tonifying Spleen Earth Qi. Why? Using Shao Yao to calm the Liver allows Liver Qi to relax, naturally ceasing its attack on Spleen Earth. Tonifying the Liver is precisely supporting the Spleen; why add excessive Ren Shen and Bai Zhu?

For this syndrome, Huang Bai Niu Che San (Yellow and White Achyrantha and Plantago Powder) is also effective. Niu Xi (Achyranthis Bidentatae Radix, 1 liang), Che Qian Zi (Plantaginis Semen, 3 qian), Huang Bo (Phellodendri Cortex, 2 qian), Bai Shao (Paeoniae Radix Alba, 1 liang). Decoct in water and take orally. Recovery in four doses.

In women, leukorrhea may appear black, flowing like ink, with the strongest fishy odor. People assume it is extreme cold, but it is actually extreme heat. Fire color should be red; why black? Extreme fire resembles water, which is an illusion. Symptoms must include abdominal pain, knife-like pain during urination, swelling of the Yin Gate, and red face. Prolonged cases lead to emaciation despite increased appetite, intense thirst, and relief after drinking water. This is Ming Men Fire (Gate of Life Fire) combining with Bladder and San Jiao (Triple Burner) fire, plus flourishing Stomach fire. Four fires roasting together inevitably boil fluids into charcoal color. Such cases do not lead to madness because Kidney Water and Lung Metal Qi flow continuously, moistening the Heart and assisting the Stomach. Thus, water entering the stomach forms leukorrhea; fire knots below but does not flare above. The treatment principle is primarily purging fire; once fire recedes, damp-heat relaxes. Use Li Huo Tang (Drain Fire Decoction): Da Huang (Rhei Radix et Rhizoma, 3 qian), Bai Zhu (Atractylodis Rhizoma, 5 qian), Fu Ling (Poria, 3 qian), Che Qian Zi (Plantaginis Semen, 3 qian), Wang Bu Liu Xing (Vaccariae Semen, 3 qian), Liu Ji Nu (Artemisiae Annuae Herba, 3 qian), Huang Lian (Coptidis Rhizoma, 3 qian), Chao Zhi Zi (Gardeniae Fructus, fried, 3 qian), Shi Gao (Gypsum Fibrosum, 5 qian), Zhi Mu (Anemarrhenae Rhizoma, 2 qian). Decoct in water and take orally. Urine flows heavily after one dose; black discharge turns white after two doses; white discharge reduces by half after three doses; full recovery after another three doses.

This formula is somewhat too rapid. However, when fire is rampant, slow methods are ineffective. Saving from fire requires urgency; hesitation allows fire to spread until extinguished. Using Huang Lian, Shi Gao, Zhi Mu, and Zhi Zi—a batch of cold-cooling fire-purging herbs—combined with Da Huang sweeps quickly. Wang Bu Liu Xing and Liu Ji Nu drain dampness urgently, leaving no room for stagnation. Assisted by Bai Zhu, Che Qian Zi, and Fu Ling, they achieve the balance of Water and Fire (Ji Ji).

For this syndrome, Qing Dai Tang (Clear Belt Decoction) is also effective. Chao Zhi Zi (Gardeniae Fructus, fried, 3 qian), Huang Bo (Phellodendri Cortex, 3 qian), Gan Cao (Glycyrrhizae Radix et Rhizoma, 1 qian), Bai Shao (Paeoniae Radix Alba, 1 liang), Che Qian Zi (Plantaginis Semen, 2 qian), Wang Bu Liu Xing (Vaccariae Semen, 2 qian), Mai Dong (Ophiopogonis Tuber, 1 liang), Xuan Shen (Scrophulariae Radix, 2 liang). Decoct in water and take orally. Recovery in four doses.

In women, leukorrhea may appear yellow, resembling strong tea juice, with a fishy odor. People consider it Spleen Meridian damp-heat, but it is actually Ren Mai (Conception Vessel) damp-heat. The Ren Mai normally cannot hold water; how does dampness enter and turn yellow? The Dai Mai connects to the Ren Mai. The Ren Mai goes straight up to the lips and teeth, where constant saliva exists. This saliva irrigates the Ren Mai downwards. If the Ren Mai has no heat, saliva transforms into essence and enters the Kidneys. Only when heat remains in the Lower Jiao does saliva fail to transform into essence and instead transform into dampness. Water color is white, fire color is red. When dampness combines with heat, it cannot turn red nor return to white. Roasted into juice, it becomes yellow. Yellow is the color of Earth. True Water and True Fire combine to form Elixir; Evil Water and Evil Fire combine to form Leukorrhea. People treat Yellow Leukorrhea as Spleen damp-heat, treating only the Spleen, which is why it is hard to cure. Use Tui Huang Tang (Retreat Yellow Decoction): Shan Yao (Dioscoreae Rhizoma, 1 liang), Qian Shi (Myristicae Arillus, 1 liang), Huang Bo (Phellodendri Cortex, 2 qian), Che Qian Zi (Plantaginis Semen, 1 qian), Bai Guo (Ginkgo Semen, 1 piece). Decoct in water and take orally. Four consecutive doses ensure complete recovery.

Any case of White Leukorrhea can be treated with this formula, especially effective for Yellow Leukorrhea. Shan Yao and Qian Shi specifically tonify Ren Mai deficiency and promote diuresis. Bai Guo guides the action into the Ren Mai, accelerating efficacy. Huang Bo clears Kidney Fire. Since the Kidney connects to the Ren Mai, clearing Kidney Fire resolves Ren Mai heat.

For this syndrome, Jie Dai Li Shi Tang (Resolve Belt and Drain Dampness Decoction) is also usable. Bai Guo (Ginkgo Semen), Fu Ling (Poria, each 1 liang), Ze Xie (Alismatis Rhizoma), Che Qian Zi (Plantaginis Semen), Chao Zhi Zi (Gardeniae Fructus, fried, each 2 qian). Decoct in water and take orally.

In women, leukorrhea may appear blue/green, resembling mung bean juice, thick and sticky, with a fishy odor. This is Liver Meridian damp-heat. Liver belongs to Wood, and Wood's color is green. Discharge resembling mung bean juice clearly indicates a Liver Wood disorder. However, Liver loves Water, and dampness is water. Why does it become Green Leukorrhea? Although Liver likes Water, it hates Heat. Combining what it hates with what it likes violates its nature. When Liver nature is violated, Liver Qi rebels. Qi desires to rise, dampness desires to sink. They pull against each other, stopping in the Middle Jiao, then moving to the Dai Mai and exiting via the Yin Gate. The blue-green color follows Liver Wood Qi. Mild rebellion means mild heat and blue color; severe rebellion means severe heat and green color. Treating blue seems easier than green. However, clearing Liver Fire and draining Bladder Water cures the disease spontaneously. Use Xiao Yao San (Free and Easy Wanderer Powder) modified: Fu Ling (Poria, 5 qian), Bai Zhu (Atractylodis Rhizoma, 5 qian), Gan Cao (Glycyrrhizae Radix et Rhizoma, 5 fen), Chen Pi (Citri Reticulatae Pericarpium, 1 qian), Chai Hu (Bupleuri Radix, 1 qian), Bai Shao (Paeoniae Radix Alba, 5 qian), Yin Chen (Artemisiae Scopariae Herba, 3 qian), Chao Zhi Zi (Gardeniae Fructus, fried, 3 qian). Decoct in water and take orally. Color fades after two doses; blue-green discharge stops after four doses; no need for more doses.

Xiao Yao San is a formula for resolving stagnation. Why is it so miraculous for Green Leukorrhea? Damp-heat retention in the Liver Meridian is due to rebellious Liver Qi. Xiao Yao San best resolves Liver rebellion. Once rebellion is calmed, damp-heat cannot remain. Added with Yin Chen to drain dampness and Zhi Zi to clear heat, the Liver Qi becomes cool. How can green discharge arise? This is why the formula is unique and effective. If one only treats Green Leukorrhea by draining dampness and clearing heat, ignoring Liver Qi, when will the discharge stop?

For this syndrome, Li Gan Jie Shi Tang (Drain Liver and Resolve Dampness Decoction) is also effective. Bai Shao (Paeoniae Radix Alba, 2 liang), Fu Ling (Poria, 1 liang), Gan Ji Guan Hua (Celosiae Cristatae Flos, dried, 5 qian), Chao Zhi Zi (Gardeniae Fructus, fried, 3 qian). Decoct in water and take orally.
