带下病都是湿证。之所以称为“带”，是因为带脉不能约束而有此病，所以以此命名。带脉与任脉、督脉相通，任脉和督脉生病后带脉才会发病。带脉的作用是约束胞胎的系带。带脉无力，就难以提起和系固，必然导致胎胞不稳固，所以说带脉虚弱则胎儿容易流产，带脉受损则胎儿不牢靠。然而带脉的损伤，不仅仅是因为跌打闪挫和气机逆乱，或者是因为行房事放纵，或者是饮酒后癫狂，虽然没有疼痛的痛苦，却有暗中耗损的危害，那么气就不能化生经水，反而变成带下病了。所以患带下病的，只有尼姑、寡妇、出嫁的女子多有，而在家的少女则很少。况且再加上脾气虚弱，肝气郁结，湿气侵袭，热气逼迫，怎么能不成为带下病呢！所以妇女中有整年整月向下流出白色物体，像鼻涕像唾沫，不能控制，甚至发臭发秽的，这就是所谓的白带。白带是湿气盛而火气衰，肝气郁结而气弱，导致脾土受伤，湿土之气下陷，因此脾精不能守持，不能化生荣血作为经水，反而变成白滑的物质，从阴门直接流下，想要自己禁止却做不到。治疗方法应当大补脾胃之气，稍微佐以舒肝的药物，使风木之气不闭塞于地中，那么地气自然升腾于天上，脾气健运而湿气消除，自然就没有带下的祸患了。
方剂用完带汤。

用水煎服。两剂症状减轻，四剂停止，六剂则白带完全痊愈。这个方子是脾、胃、肝三经同治的方法，在散邪中寓含补益，在消导中寄托升提，开启肝木之气，则肝血不燥，何至于下克脾土；补益脾土的元气，则脾气不湿，何难分消水气。至于补脾的同时兼以补胃，是由里及表的关系。脾如果没有胃气的强盛，那么脾的虚弱就不能旺盛，这是补胃正是为了补脾罢了。
眉批：妇科这一门类，最属难治，不难在于用方，难在于辨证。五种带下症辨别得极其明白，立方极其善妙，如果用了不生效的，必定是经水不调，需要在调经、种子两个门类中参考斟酌治疗，没有不见效的。就像白带症，如果服药不生效，这个人必定月经过期，少腹急迫，应该服用宽带汤，其余适宜类似参考，见第二十三页。

Leukorrhea is fundamentally a dampness syndrome. It is named "dai" (belt) because the Dai Mai (Girdle Vessel) fails to constrain, leading to this condition. 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 subsequently becomes affected. The function of the Dai Mai is to constrain the ligaments of the uterus. If the Dai Mai lacks strength, it cannot lift and secure, inevitably resulting in an unstable uterus; thus, it is said that if the Dai Mai is weak, pregnancy is prone to miscarriage, and if damaged, the fetus is insecure. However, injury to the Dai Mai is not solely due to falls, sprains, or qi stagnation from trauma, nor only from excessive sexual activity or drunken madness. Although there may be no acute pain, there is insidious consumption of essence. Consequently, qi fails to transform menstrual blood, instead turning into leukorrhea. Therefore, women suffering from leukorrhea are mostly nuns, widows, or married women, while virgins rarely suffer from it. Furthermore, compounded by spleen qi deficiency, liver qi stagnation, invasion of dampness, and pressure from heat, how can one avoid developing leukorrhea? Thus, some women experience a continuous flow of white discharge throughout the year, resembling mucus or saliva, which they cannot control, sometimes even becoming foul-smelling. This is what is referred to as "white leukorrhea." White leukorrhea arises from excess dampness and deficient fire, liver stagnation and weak qi, which injure the Spleen Earth. The qi of damp-earth sinks downward, causing the Spleen's essence to fail to remain stored. It cannot transform nutritious blood into menstrual blood, but instead transforms into slippery white matter, flowing directly from the vagina, impossible to stop voluntarily. The treatment method should heavily tonify Spleen and Stomach qi, slightly assisting with herbs that soothe the Liver. This ensures that Wood qi does not become blocked within the earth, allowing earth qi to naturally rise to heaven. When Spleen qi is robust and dampness dissipates, leukorrhea will naturally cease.
The formula used is Wandai Tang (Complete Belt Decoction).
Baizhu (Atractylodis Rhizoma, 1 liang, stir-fried with soil), Shanyao (Dioscoreae Rhizoma, 1 liang, stir-fried), Renshen (Ginseng Radix et Rhizoma, 2 qian), Baishao (Paeoniae Radix Alba, 5 qian, stir-fried with wine), Cheqianzi (Plantaginis Semen, 3 qian, stir-fried with wine), Cangzhu (Atractylodis Rhizoma, 3 qian, processed), Gancao (Glycyrrhizae Radix et Rhizoma, 1 qian), Chenpi (Citri Reticulatae Pericarpium, 5 fen), Hei Jiesui (Schizonepetae Spica, charred, 5 fen), Chaihu (Bupleuri Radix, 6 fen).
Decoct in water and take orally. Symptoms alleviate after two doses, stop after four doses, and resolve completely after six doses. This formula treats the Spleen, Stomach, and Liver meridians simultaneously. It incorporates tonification within dispersal and embedding reduction within lifting. By opening the Qi of Liver Wood, Liver blood remains moist, preventing it from overacting on Spleen Earth. By tonifying the primal qi of Spleen Earth, Spleen qi remains dry, facilitating the dispersion of fluid metabolism. Tonifying the Spleen while concurrently tonifying the Stomach reflects the relationship from interior to exterior. Without strong Stomach qi, Spleen weakness cannot be revitalized; thus, tonifying the Stomach is precisely how one tonifies the Spleen.
Marginal Note: The field of gynecology is notoriously difficult to treat. The difficulty lies not in prescribing formulas but in syndrome differentiation. The differentiation of the five types of leukorrhea is extremely clear, and the formulated prescriptions are excellent. If a prescription proves ineffective, it is likely due to irregular menstruation, requiring consideration of treatments for regulating menstruation and promoting conception, which will invariably yield results. For instance, in cases of white leukorrhea where medication fails, if the patient also experiences delayed menstruation and lower abdominal urgency, Kuandai Tang (Loose Belt Decoction) should be administered. Other cases should be referenced similarly, see page 23.
Verse:
Women flow white matter all year round,
Like mucus and saliva, often foul and sour.
Spleen deficiency, Liver stagnation, Dampness prevails,
Ren and Du diseases make the Belt vessel fail its constraints.
Wandai uses fried Baizhu and Shanyao,
With Renshen, Baishao, Cheqian, Cangzhu, and raw Gancao.
Chenpi, Chaihu, and charred Schizonepeta,
When Spleen qi is robust, Dampness naturally dissipates.
