〔凡久病之后，大便一月不通者，不必性急，止补其真阴，使精足自生血，血足以润肠，大便自出，不可视为
报本之病，而速其愈也。〕方用∶
熟地（一两） 元参（一两） 当归（一两） 川芎（五钱） 桃仁（十粒） 火麻仁（一钱） 大黄（一钱）
红花（三分） 蜜（半杯）
水煎服。
〔此方妙在用熟地、元参、当归以生阴血，少加麻仁、大
黄以润肠下行，此正末治其闭结，而不急急以通之也。〕
〔小便不通，乃膀胱之病〕，膀胱之气化不行，小便即不能出。小便闭塞，治膀胱之经而已矣，然而治法全
不在治膀胱也。方用∶
人参（三钱） 莲子（三钱） 茯苓（三钱） 甘草（一钱） 肉桂（一钱） 白果（二钱） 车前子（一钱）
王不留（一钱）
水煎服。
此方妙在用人参、肉桂。盖膀胱必得气化而始出。气化者何？心胞络之气也。〔膀胱必得心包络之气下行，而
水路始能出。〕既用参、桂，而气化行矣，尤妙在用白果，人多不识此意。白果通任、督之脉，又走膀胱，（引
参、桂之气，直奔于膀胱之中），况车前子，王不留尽是下泄之药，服之而前阴有不利者乎？
小便不通，方用∶
熟地（一两） 山萸（四钱） 丹皮（一钱） 山药（一钱） 肉桂（一钱） 车前子（一钱） 泽泻（一钱） 茯
苓（二钱）
此方〔即七味地黄汤〕，妙在不去通小便，而专治肾水。肾中有水，而膀胱之气自行矣。盖膀胱之开合，肾司其
权也。
In cases where bowel movements are obstructed for a month following a prolonged illness, there is no need to be impatient. One should merely tonify the True Yin (Zhen Yin), so that sufficient essence naturally generates blood; when blood is abundant, it moistens the intestines, and bowel movements will occur spontaneously. It should not be regarded as a condition requiring urgent resolution to hasten recovery. The prescription is as follows: Shu Di Huang (Prepared Rehmanniae Radix, 1 liang), Yuan Shen (Scrophulariae Radix, 1 liang), Dang Gui (Angelicae Sinensis Radix, 1 liang), Chuan Xiong (Ligustici Chuanxiong Rhizoma, 5 qian), Tao Ren (Persicae Semen, 10 grains), Huo Ma Ren (Cannabis Fructus, 1 qian), Da Huang (Rhei Radix et Rhizoma, 1 qian), Hong Hua (Carthami Flos, 3 fen), Honey (half cup). Decoct in water and take orally.
The brilliance of this formula lies in using Shu Di Huang, Yuan Shen, and Dang Gui to generate Yin-blood, with small amounts of Huo Ma Ren and Da Huang added to moisten the intestines and promote downward movement. This addresses the root cause of the obstruction rather than hastily forcing evacuation.
Obstruction of urination is a disease of the Bladder (Pang Guang). If the Qi transformation (Qi Hua) of the Bladder fails, urine cannot be excreted. Although urinary retention involves the meridians of the Bladder, the treatment method does not lie primarily in treating the Bladder itself. The prescription is as follows: Ren Shen (Ginseng Radix, 3 qian), Lian Zi (Nelumbinis Semen, 3 qian), Fu Ling (Poria, 3 qian), Gan Cao (Glycyrrhizae Radix et Rhizoma, 1 qian), Rou Gui (Cinnamomi Cortex, 1 qian), Bai Guo (Ginkgo Semen, 2 qian), Che Qian Zi (Plantaginis Semen, 1 qian), Wang Bu Liu Xing (Vaccariae Semen, 1 qian). Decoct in water and take orally.
The brilliance of this formula lies in the use of Ren Shen and Rou Gui. The Bladder requires Qi transformation to excrete urine. What is Qi transformation? It is the Qi of the Pericardium Collateral (Xin Bao Luo). The Bladder must receive the descending Qi of the Pericardium Collateral for the water passages to flow freely. Having used Ren Shen and Rou Gui, Qi transformation is activated. Particularly ingenious is the use of Bai Guo, an aspect often misunderstood. Bai Guo unblocks the Ren Mai (Conception Vessel) and Du Mai (Governor Vessel) and acts upon the Bladder (guiding the Qi of Ren Shen and Rou Gui directly into the Bladder). Moreover, since Che Qian Zi and Wang Bu Liu Xing are herbs that promote downward drainage, would they not facilitate smooth urination from the anterior orifice?
For obstruction of urination, another prescription is used: Shu Di Huang (Prepared Rehmanniae Radix, 1 liang), Shan Yu Rou (Corni Fructus, 4 qian), Dan Pi (Moutan Cortex, 1 qian), Shan Yao (Dioscoreae Rhizoma, 1 qian), Rou Gui (Cinnamomi Cortex, 1 qian), Che Qian Zi (Plantaginis Semen, 1 qian), Ze Xie (Alismatis Rhizoma, 1 qian), Fu Ling (Poria, 2 qian). This formula is essentially Liu Wei Di Huang Tang (Six-Ingredient Pill with Rehmannia) modified to Qi Wei Di Huang Tang (Seven-Ingredient Kidney-Nourishing Decoction). Its brilliance lies not in promoting diuresis but in specifically treating Kidney Water. When there is sufficient Water in the Kidneys, the Qi transformation of the Bladder functions naturally. The opening and closing of the Bladder are governed by the Kidneys.
