(Small urine volume is normal. Xu, Shen, Zhou, You, and Zhu's editions read "small urine volume is difficult," which should be adopted.)
The pulse at the cunkou position is floating and slow.
According to Chao Yuanyuan's view, classifying this clause under the syndrome of deficiency labor confirms the correctness of the statement in *Yizong Jinjian*.
The pulse at the fuyang position is floating and rapid.
*Zhengzhi Yaojue* states: Middle Xiao (Middle Wasting-Thirst) affects the spleen; spleen qi is hot and dry, food intake doubles, and all is transformed into small urine for excretion.
Men suffering from Xiao (Wasting-Thirst) have an increased volume of small urine.
[Yu's Commentary] According to this text, the description of true Xiao (Wasting-Thirst) contains only these two syndromes, namely Middle Xiao and Lower Xiao. Although *Gujin Luyan* divides it into three Xiao, it is essentially a disease of the spleen and kidney organs. The symptom of thirst must originate from stomach heat; heat in the upper jiao causes only dryness of the throat. The phrase "dry mouth but no desire to drink" refers to cases where there is heat in the diaphragm but no heat in the stomach. Given this, Zhang Zhongjing's omission of Upper Xiao reveals his intent. It was not until the philosophers of the Song and Jin dynasties that the Three Xiao were correlated with the Three Jiao (as seen in *Weisheng Jiabao*, *Jianyi Fang*, *Zhi Zhi Fang*, *Baoming Ji*, etc.). Recently, Wada Taijun questioned this theory, arguing it is not without merit. However, *Neijing* mentions Lung Xiao and Diaphragm Xiao. Furthermore, in Jueyin disease, there is already a Xiao (Wasting-Thirst) syndrome, caused by exhaustion of stomach fluids extending to the chest area. Therefore, one cannot assert that Upper Xiao syndromes do not exist. I dare not speculate arbitrarily and leave this for scholars to verify.
When there is a desire to drink water and drinking does not relieve the thirst:
[Shen] This is also not true Xiao (Wasting-Thirst).
According to You Shi: Heat-induced thirst leads to drinking, but the water entering the body fails to eliminate the heat and is instead consumed by the heat, resulting in unrelenting thirst. Wen Ge (Clam Shell) is salty and cold; cold can eliminate heat, and saltiness can moisten and direct downward. It is used to curb the upward-flaring pathogenic factor and cure heat-induced thirst. This is another interpretation, preserved here for reference. When small urine volume is difficult, it indicates the presence of fluid retention.
Zhu Shi believed that heat in the upper jiao and cold in the lower jiao cause difficulty in urination due to thirst, which is incorrect. The thirst in this syndrome is caused by fluid retention in the lower jiao, leading to abnormal ascending of qi and fluids. Gualou Gen (Trichosanthes Root) not only generates body fluids but also promotes the movement of fluid retention. This can be observed in the use of Chaihu Guizhi Ganjiang Tang (this formula treats fluid accumulation, see commentary in *Shanghan Lun Shuyi*) and Muli Zexie San. For treating urinary obstruction, Shenqi Wan (Kidney Qi Pill) should be used; it is particularly effective for patients who crave mud. In Weishi's *De Xiao Fang*, Fuzi San (Aconite Powder) treats urinary obstruction with deep and faint pulses at both chi positions, indicating yin deficiency. Using Mian Fuzi (Prepared Aconite Root), Zexie (Alisma Rhizome), each 1 liang, and Dengxin Cao (Juncus Effusus Stem) 7 stems, decocted in water and taken orally, follows this same principle.
If there is a desire to drink water accompanied by a dry mouth and tongue:
According to this clause appearing in the Yangming chapter, it still pertains to (Yangming heat excess) and seems not to be true Xiao (Wasting-Thirst). However, using it as a treatment for Middle Xiao syndrome is acceptable.
Zhuling Tang Formula
Zhuling (Poria, peeled), Fuling (Poria), Ejiao (Donkey-hide Gelatin), Huashi (Talcum), Zexie (Alisma Rhizome) (each 1 liang)
Take the above five herbs, add four sheng of water, first decoct the first four herbs to obtain two sheng of liquid, remove the dregs, add Ejiao (Donkey-hide Gelatin) and melt it. Take seven ge warm, three times a day. (Note: This formula was accidentally omitted in the collected meanings; it is now recorded and supplemented according to the original text.)
