Qin Yueren stated: When the Dai Mai (Girdle Vessel) is diseased, there is abdominal fullness, and the waist feels loose and weak, as if sitting in water. ("Rongrong" describes a slow, relaxed appearance.)

The *Mingtang Jing* (Classic of the Bright Hall) states: The Dai Mai acupoints (two in number) mainly treat symptoms of the waist and abdomen being loose and flaccid, feeling as if a sack filled with water. For women with lower abdominal pain, tenesmus, convulsions, irregular menstruation, and red or white leukorrhea, needle insertion should be six fen, and moxibustion seven zhuang.

Zhang Jiegu stated: Diseases of the Dai Mai are governed by the Taiyin channel; it is appropriate to apply moxibustion to Zhangmen (LR13), two points, three zhuang each.

The *Suwen* (Basic Questions) states: When pathogenic factors invade the collaterals of the Taiyin, it causes lower back pain radiating to the lower abdomen and controlling the hypochondriac region, making it impossible to rest comfortably. ("Kou" refers to the soft area below the floating ribs.)

Zhang Zhongjing stated: After a major illness has subsided, if there is water qi accumulation below the waist, Muli Zexie San (Oyster Shell and Alisma Powder) is the primary formula. If the condition does not improve, moxibustion on Zhangmen (LR13) should be applied.

Wang Shuhe stated: Disease of the Dai Mai involves pain winding around the navel on both sides, lower back and spine pain, and radiation to the inner thighs.

Wang Haizang stated: Infantile hernia can be cured by applying moxibustion to Zhangmen (LR13) for three zhuang, because this point lies in the distribution of the Jueyin channel where the Dai Mai runs, and is governed by the Taiyin.

He further stated: For women suffering from menstrual disorders leading to metrorrhagia, which becomes depleted over time, astringent and tonifying methods should be used. For blood stasis leading to exhaustion due to long-term obstruction, tonifying and breaking methods should be used. There are three stages for breaking blood stasis: initially, Siwu Tang (Four Substances Decoction) with Honghua (Carthami Flos) is taken with Huangbai (Phellodendri Cortex) and Rougui (Cinnamomi Cortex); secondly, Siwu Tang with Honghua is taken with Linglijia (Manis Squama), Taoren (Persicae Semen), and Guizhi (Cinnamomi Ramulus), decocted with Tongzi Xiaoye (Child's Urine) and wine; finally, Siwu Tang with Honghua is taken with Yilao Moyao San (Yilao Myrrh Powder).

Zihe Zheng stated: The twelve regular meridians and the seven extraordinary vessels all circulate up and down. Only the Dai Mai originates from the side of the lower abdomen, below the hypochondrium, encircles the body once, passes through the waist, and resembles a girdle. The Chong Mai (Penetrating Vessel) and Ren Mai (Conception Vessel) follow the abdomen and hypochondrium, flank the umbilicus, flow into Qichong (ST30), belong to the Dai Mai, and connect with the Du Mai (Governor Vessel). These three vessels—Chong, Ren, and Du—share the same origin but have different pathways, forming one source that branches into three, and all connect with the Dai Mai. Because the regular meridians move up and down, they leave residual heat in the Dai Mai. This pathogenic heat stagnates, causing white discharge to overflow and flow out with urine continuously, which is called white leukorrhea. The *Neijing* states: "Endless thoughts, unfulfilled desires, mental lust directed outward, and excessive sexual activity lead to sinew atrophy and 'white yin'." White yin refers to the profuse discharge of white material resembling semen; in men, it flows out with urine; in women, it flows continuously. These conditions should be treated based on damp-heat, using the same method as treating dysentery. Red and white dysentery results from pathogenic heat transmitting to the Large Intestine; red and white leukorrhea results from pathogenic heat transmitting to the Small Intestine. Later generations mistakenly believed that red indicates heat and white indicates cold, an error propagated for millennia due to physicians' misunderstandings. He also said: *Zisheng Jing* records a woman suffering from red and white leukorrhea. Someone moxibusted Qihai (CV6) without effect. The next day, someone moxibusted the DaMai (EX-B4) acupoint. A ghost whispered, "Moxibustion yesterday was good, but you missed me. Today you hit me, so I am leaving." It requested wine and food offerings. The family followed these instructions, and she recovered. I initially found this strange, recalling the story of Jin Jinggong's two ghosts in the Gaohuang region, which occurred when deficiency consumption was severe, allowing ghosts to occupy the void. This woman likely suffered from mental labor and deficiency, allowing ghosts to reside there. Once the moxibustion accurately targeted the acupoint, the ghosts had to leave. Since then, whenever patients presented with this condition, pressing this acupoint always elicited immediate soreness and pain. Instructing them to moxibustate it resulted in recovery every time. This acupoint is located 1.8 cun below the costal margin in the hypochondriac region. Moxibustion on Baihui (GV20) is especially beneficial. The *Neijing* states: "For diseases above, treat below; for diseases below, treat above." It also says: "Treat high lesions by lowering them, treat low lesions by raising them." This is correct.

Liu Zongnong stated: Leukorrhea mostly originates from Yin deficiency and Yang exhaustion, failure of Ying Qi to ascend, stagnation of meridians, and sinking of Wei Qi. Essence and Qi accumulate in the lower Jiao within the extraordinary vessels, fermenting and transforming. It is named after the Dai Mai disease and the shape of the pathology: white relates to Qi, red relates to Blood. It is often caused by drunkenness, overeating, sexual excess, or taking dry-hot drugs. It can also result from damp-phlegm flowing into the lower Jiao, or excessive dampness from Kidney and Liver Yin. It may arise from fright causing Wood to overact on Earth, leading to turbid fluids flowing downward; or endless longing causing sinew atrophy, known as "diseases of the Two Yang originating from Heart and Spleen"; or damp-heat from other meridians stagnating in the lower abdomen; or deficiency-cold of the Lower Yuan with dampness flooding the Uterus. Treatment methods vary: purging, vomiting, combining attack with tonification, combining tonification with draining, combining drying with ascending, combining moistening with warming, using warm-aromatics, or using astringents. Each case differs, representing flexible applications of pathogenesis treatment.

Chao Yuanyifang in *Bingyuan* (Source of Diseases) stated: Shen Zhuo Bing (Kidney Fixation Disease) presents with lower back pain cold as ice, heavy body, and a waist feeling as heavy as carrying five thousand coins. There is no thirst, urination is free. It is contracted from sweating during labor, with cold-damp clothing sticking to the skin. Over time, it transforms into water retention. *Qianjin Fang* uses Shen Zhuo Tang (Kidney Fixation Decoction), *San Yin Fang* uses Shen Shi Tang (Damp-Permeating Decoction), and Li Dongyuan uses Duhuo Tang (Angelica Pubescens Decoction) as primary treatments.
