肾中真阳虚而泄泻者，每于五更时，或天将明，即洞泄数次，此由丹田不暖，所以尾闾不固，或先肠鸣，
或脐下痛，或经月不止，或暂愈复作，此为肾泄。盖肾为胃关，二便开闭，皆肾脏所主。今肾阳衰，则阴寒盛，
故于五更后，阳气未复，即洞泄难忍。古方治肾泄，用椒附丸、五味子散。若欲阳生于阴，肾气充固，宜八
味丸去丹皮，加补骨脂、菟丝子、五味子，用山药糊丸为妙。
泻由水谷不分，病在中焦。痢以脂血伤败，病在下焦。在中焦者，分利脾胃之湿。在下焦者，调理肝肾
之伤。若水泻久，则传变而痢脓血，是脾传肾，谓之贼邪，故难愈。若先痢后泻，是肾传脾，谓之微邪，故
易瘳。
胃脉虚则泻，脉滑，按之虚，必下利。肾脉微小则洞泄，肺脉微甚则泄。泄泻脉洪大者逆，泄而脱血
脉实者，难治。泄泻脉缓，时小结者生，浮大数者死。泻脉多沉，沉迟寒促，沉数火热，沉虚滑脱。暑湿缓弱，
多在夏月。

For diarrhea caused by deficiency of the true Yang in the Kidney, it often occurs several times with watery stools during the fifth watch (5:00-7:00 AM) or just before dawn. This is due to the lack of warmth in the Dantian (the gathering place of Yuan Qi in the lower Jiao), leading to insecurity of the Weilu (referring to the anus or the consolidating function of the lower Yuan). Symptoms may include borborygmus first, or pain below the umbilicus, or a course lasting for months without cessation, or temporary remission followed by recurrence; this is called Kidney Diarrhea. The Kidney serves as the gate of the Stomach, and the opening and closing of urination and defecation are all governed by the Kidneys. Now that Kidney Yang is declining, Yin-Cold becomes excessive, so after the fifth watch, when Yang Qi has not yet recovered, unbearable watery diarrhea occurs. Ancient formulas for treating Kidney Diarrhea use Jiaofu Wan (Pepper and Aconite Pill) and Wuweizi San (Schisandra Powder). If one wishes for Yang to arise from Yin and for Kidney Qi to be abundant and solid, it is suitable to use Bawei Wan (Eight-Ingredient Pill) removing Mudanpi (Moutan Cortex), adding Buguzhi (Psoraleae Fructus), Tusizi (Cuscutae Semen), and Wuweizi (Schisandrae Fructus), made into pills using Yam paste for optimal effect.
Diarrhea arises from the failure to distinguish between water and grain, with the pathology located in the Middle Jiao. Dysentery results from the damage and corruption of mucus and blood, with the pathology located in the Lower Jiao. For pathology in the Middle Jiao, treatment involves separating and draining the dampness of the Spleen and Stomach. For pathology in the Lower Jiao, treatment involves regulating the injury to the Liver and Kidney. If watery diarrhea persists for a long time, it may transform into dysentery with pus and blood; this is the transmission of Spleen disease to the Kidney, termed "Thief Evil" (Zei Xie), making it difficult to cure. If dysentery precedes diarrhea, this is the transmission of Kidney disease to the Spleen, termed "Minor Evil" (Wei Xie), making it easy to heal.
Deficiency of the Stomach pulse leads to diarrhea; if the pulse is slippery but feels deficient upon deep pressure, there must be downward discharge. A minute and small Kidney pulse indicates severe watery diarrhea; an extremely weak or excessive Lung pulse indicates diarrhea. A洪大 (Hong Da / Surging and Large) pulse in diarrhea is a counter-indication (poor prognosis); diarrhea accompanied by hemorrhage with a excess pulse is difficult to treat. A slow pulse in diarrhea, occasionally with small knotted beats, indicates survival (good prognosis); a floating, large, and rapid pulse indicates death (very poor prognosis). The pulse in diarrhea is mostly deep; deep and slow indicates cold stagnation, deep and rapid indicates internal heat/fire, and deep and deficient indicates sliding and incontinence. Diarrhea caused by summerheat-dampness presents with a slow and weak pulse, mostly occurring in summer.
