Xue Zhuzhai stated: Xu Yongcheng said that leukorrhea that is white belongs to Qi pathology, while that which is red belongs to Blood pathology. Li Dongyuan said that prolonged blood flooding (profuse uterine bleeding) leads to Yang collapse; therefore, the discharge of slippery white substances does not necessarily adhere strictly to the pathology of the Dai Mai (Girdle Vessel).

I humbly believe that the aforementioned syndromes may arise from the Six Excesses (Wind, Cold, Summerheat, Dampness, Dryness, Fire) or Seven Emotions (Joy, Anger, Worry, Pensive anxiety, Sorrow, Fear, Fright), or from excessive drinking and overeating, sexual indiscretion, rich and greasy dietary habits, or the use of drying agents. These factors cause damage to the Spleen and Stomach, sinking of Yang Qi, or downward pouring of Damp-Phlegm, accumulating to form the condition known as "Leukorrhea." All such cases should be treated primarily by strengthening the Spleen and Stomach and raising Yang Qi, supplemented by herbs targeting the specific meridian manifestations. If the color is green, it relates to the Liver; use Xiao Chai Hu Tang (Minor Bupleurum Decoction) with Shan Zhi (Gardeniae Fructus) and Fang Feng (Saposhnikoviae Radix). If Damp-Heat is congested and stagnant, causing red and scanty urination, use Long Dan Xie Gan Tang (Gentian Liver-Draining Decoction). If Liver Blood is insufficient, or there is Dryness-Wind or Wind-Heat, use Liu Wei Wan (Six-Ingredient Rehmannia Pill). If the color is red, it relates to the Heart; use Xiao Chai Hu Tang with Huang Lian (Coptidis Rhizoma), Shan Zhi, and Dang Gui (Angelicae Sinensis Radix). If excessive pensive anxiety causes injury, use Miao Xiang San (Wonderful Fragrance Powder). If the color is white, it relates to the Lung; use Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) with Shan Zhi. If the color is yellow, it relates to the Spleen; use Liu Jun Zi Tang (Six-Gentlemen Decoction) with Shan Zhi and Chai Hu (Bupleuri Radix); if ineffective, use Gui Pi Tang (Restore the Spleen Decoction). If the color is black, it relates to the Kidney; use Liu Wei Wan. If both Qi and Blood are deficient, use Ba Zhen Tang (Eight-Treasure Decoction). If Yang Qi is sinking, use Bu Zhong Yi Qi Tang. If Damp-Phlegm pours downward, add Fu Ling (Poria), Ban Xia (Pinelliae Rhizoma), Cang Zhu (Atractylodis Rhizoma), and Huang Bai (Phellodendri Cortex) to Bu Zhong Yi Qi Tang. If Qi deficiency leads to Phlegm-Fluid pouring downward, use Si Qi Tang (Four-Seven Decoction) to administer Liu Wei Wan. One must not rigidly adhere to the notion that "fat people have much Phlegm, thin people have much Fire," and thus lightly treat them with drying-dampness or draining-fire herbs.

Shenzhai’s commentary: The above seven points outline the general principles for treating leukorrhea. Leukorrhea varies in nature into Cold-Damp, Damp-Heat, Deficiency, and Excess; hence, various schools’ treatments differ between purgation, warming, and tonification. For instance, He Jianzi (Zhang Hehe), Taiwu, and Jiegu (Jin Suo) employed purgative methods. Danxi (Zhu Zhenheng), Yuozhi, and Zongnong used a combination of attacking and tonifying. Regarding Yang Renzhai and Xue Lizhai, they established their theories on strengthening the Spleen and Stomach, aligning with the principles of Dongyuan (Li Dongyuan) and Zhongchun (Miao Fu). Wu Meipo treated by tonifying the Kidney and consolidating the root, anticipating the ideas of Yangkui. These all represent profound scholarship that explores the root and source. They differ in terms of root vs. branch and interior vs. exterior from the drying-dampness and clearing-heat approaches of Zhang Yuansu and Liu Wansu, and Danxi’s phlegm-resolving, ascending, and astringing methods. Readers should integrate these concepts comprehensively.
