Dai Yuanli stated: Both red and white leukorrhea are caused by internal injury from the seven emotions (joy, anger, worry, thought, sadness, fear, fright) or deficiency-cold of the lower jiao (lower burner). The etiology is not singular. Generally, white discharge is more common, with occasional red discharge. For both, Shunqi San (Qi-Smoothing Powder) should be taken, along with swallowing Zhenling Dan (Vibrating Spirit Pill), assisted by Aifu Wan (Mugwort and Cinnamon Twig Pill), or taking Sand Shen Mo (Ginseng Radicle Powder) mixed with rice water. If leukorrhea persists leading to emaciation, Siwu Tang (Four Substances Decoction) added with Ban Qian of Muli Fen (Oyster Shell Powder) should be used, swallowing Guchang Wan (Intestine-Securing Pill); prolonged administration yields efficacy. In cases where leukorrhea recurs one or two months after recovery, or once every half year, presenting first with blood followed by discharge, coming uncontrollably and then stopping briefly before pouring out again, this is named Loudai (Leaking Leukorrhea), which is most difficult to treat (The name "Loudai" originates here; it may also be curable through lifting and tonifying methods). Lower bleeding is governed by the Shaofu (Lower Abdomen). Some cases involve deficiency-heat sinking into the Xiaochang (Small Intestine) due to blood deficiency, causing dysuria with pain, urine resembling rice washings, or forming sand-like particles. These must not be treated as Lin syndrome (Dysuria) using cold-natured agents. Instead, Siwu Tang (Four Substances Decoction) and Wuling Yin (Five Ling Drink) should be combined in equal halves and decocted together. (This method of decocting drying-dampness herbs together was uniquely created by Dai Yuanli; without reading this, one would not know to use this approach.)

*Chanbao* (Treasures for Childbirth) states: There are three diseases affecting unmarried women. What are they? The answer is: The first disease occurs when menstruation first begins, heat arises in the yin region, lying exposed to wind, or fanning oneself; the second disease involves a flourishing Taichong Mai (Great冲 Vessel), where excess qi generates internal heat, washed with cold water; the third disease involves being frightened by the sight of leukorrhea. If any of these three conditions are contracted, leukorrhea symptoms will inevitably follow later. (The formula used is Shenxian Jubao Dan (Immortal's Treasure-Gathering Pill).)

*Zhunsuo* (Standard Mirror) states: Leukorrhea mixed with intestinal contents presents with persistent leakage of foul pus, extremely offensive odor, leading to increased cold pain in the umbilical and abdominal regions. This is caused by foul pus and blood, with no imminent end. One must use this formula to drain pus: Bai Zhi (Angelicae Dahuricae Radix) 1 liang, Danye Hong Shukui Gen (Root of Malva Verticillata) 2 liang, Bai Shao Yao (Paeoniae Radix Alba) and Bie Jian Bai Fan (Burnt Alum) calcined until dry, each 0.5 liang. Take 10 or 15 pills on an empty stomach or before meals with rice water. Wait until the pus is exhausted, then assist with tonic medicines. (In this formula, Bai Zhi and Shukui Gen drain pus and disperse blood; Bai Shao generates flesh; dried alum dries dampness; combined with beeswax, this constitutes a treatment for generating flesh and supporting the interior. *Maijing* states: Pus in the intestines of women results from conflict between Ying and Wei (Nutritive and Defensive Qi). Blood becomes turbid waste; there are distinctions between what can be purged and what cannot; reference should be made to this.)
