肾劳，是指真阴长期亏损，或因房事过度，导致下焦水液枯竭，上焦虚火炎上，出现身体发热、腰部疼痛、咽喉干燥、口舌燥渴等症状，严重时甚至咳嗽、吐血，主方用来自制的来苏汤。

先生制定此方，依据《难经》中“损其肾者益其精”的原则。精，属水，但畏惧火邪；若火动则精不能安居其宅，从而引发肾劳。因此，想要补益精气，必须先制约火邪；所谓制约火邪，并非指使用知母、黄柏等苦寒药物泻火，而是通过壮水之主以配阳火。方中天冬、麦冬、南沙参、北沙参，用于壮水滋阴；白芍、赤芍用于清泄心肝之火；杜仲、沙苑子、磁石用于补肾固精并纳气归元；贝母、杏仁用于宣通心肺之气；茜草根、牛膝用于引导上行之血下行；而莲子则用于安定上下君相之火，交通心肾。如此则水旺火平，实现水火既济，未耗损的精气得以安宁，已耗损的精气得以再生。治疗五劳的补方中，不使用一味助火之药，因为“劳”字上半部分包含两个“火”字。祖怡注。
五脏六腑，化生并滋养气血；气血旺盛，才能营养脏腑。虚劳内伤，不出气血两方面的病变。治疗气血虚弱，没有比调理脾肾更重要的了。水是天一之元，气的根本在肾；土是万物之母，血的统摄在脾。若气血旺盛，脾肾二脏健康，即使其他脏腑有所不足，充足的气血也能供给灌注，全身相生相养，各种疾病自然痊愈。人如果劳心过度、纵欲无度，起初往往不自察觉，等到越劳累越虚弱时，胃中摄入的水谷所化生的一日精血，不足以维持一日之用，于是营血逐渐消耗，真气日益亏虚，出现头晕耳鸣、心烦神疲、口燥咽干、食少短气、腰酸足软等各种症状，严重时甚至咳嗽失音、吐血盗汗，生命便处于危险境地。孙思邈说补脾不如补肾，许叔微说补肾不如补脾，这两位先哲深知脾肾两脏是人生存的根本，具有相互资助的功能，他们的说法看似相反，实则宗旨相辅相成。救治肾虚者必基于阴血，血主濡润，性质主下降，虚证时易上升，应当收敛使其下降。救治脾虚者必基于阳气，气主温煦，性质主上升，虚证时易下陷，应当升举使其上升。近代人治疗虚劳，不是用四物汤加知母、黄柏，就是用大造丸加龟板、黄柏，一派阴寒腥浊的药性，将脾胃生长之气置于何地？这不是在补养气血，而是在败坏气血。因此创立两种方法以纠正这种弊端。

Shen Lao (Kidney Exhaustion) refers to a condition where the True Yin has been deficient for a long time, or due to excessive sexual activity, leading to exhaustion of Water in the Lower Jiao and flaming of Fire in the Upper Jiao. Symptoms include body heat, lower back pain, dry throat, and dry mouth; in severe cases, coughing and hemoptysis may occur. The primary formula is Laisu Tang (Laisu Decoction), a self-made prescription.

The author formulated this prescription based on the principle from *Nan Jing* (Classic of Difficult Issues): "For those with kidney damage, benefit their Essence." Essence belongs to Water but fears Fire; if Fire moves, Essence cannot remain stable in its residence, leading to Kidney Exhaustion. Therefore, to tonify Essence, one must first control Fire. Controlling Fire does not refer to using bitter-cold herbs like Zhi Mu (Anemarrhenae Rhizoma) and Huang Bo (Phellodendri Cortex) to purge fire, but rather strengthening Water to balance Fire. Tian Dong, Mai Dong, Nan Sha Shen, and Bei Sha Shen are used to strengthen Water; Bai Shao and Chi Shao clear Heart and Liver heat; Du Zhong, Sha Yuan, and Ci Shi tonify the Kidney, secure Essence, and grasp Qi; Bei Mu and Xing Ren ventilate Lung and Heart Qi; Qian Cao Gen and Niu Xi guide ascending Blood downward; and Lian Zi calms the Ministerial and Sovereign Fire above and below, facilitating communication between Heart and Kidney. Thus, Water becomes abundant and Fire levels out, achieving Water-Fire Balance (Shui Huo Ji Ji). Unconsumed Essence remains safe, and consumed Essence can regenerate. In tonifying formulas for Wu Lao (Five Excesses), no herb that aids Fire is used, because the character "Lao" contains two "Fire" radicals at the top. Note by Zu Yi.
The Five Zang and Six Fu organs transform and generate Qi and Blood; when Qi and Blood are vigorous, they nourish the organs. Deficiency consumptive diseases (Xu Lao) internal injury do not go beyond the two pathways of Qi and Blood. In treating Qi and Blood deficiency, nothing is more important than regulating Spleen and Kidney. Water is the origin of Tian Yi (Heavenly One); the root of Qi lies in the Kidney. Earth is the mother of all things; the control of Blood lies in the Spleen. If Qi and Blood are vigorous and these two organs are healthy, even if other organs have deficiencies, sufficient Qi and Blood can be supplied and infused, promoting mutual generation among all parts, and various diseases will resolve themselves. If a person overworks their mind and indulges desires, initially they may not realize it. However, as fatigue leads to greater deficiency, the Essence and Blood generated daily from food and drink ingested by the Stomach become insufficient for daily use. Consequently, Ying Blood (Nutritive Blood) gradually depletes, and True Qi declines daily. Symptoms such as dizziness, tinnitus, mental restlessness, fatigue, dry mouth and throat, poor appetite, shortness of breath, soreness and weakness of the lower back and feet appear. In severe cases, coughing, loss of voice, hemoptysis, and night sweats occur, endangering life. Sun Simiao stated that tonifying the Spleen is better than tonifying the Kidney; Xu Shuwei stated that tonifying the Kidney is better than tonifying the Spleen. These two sages deeply understood that these two organs are the foundation of human life and possess mutually supportive functions. Their theories seem opposite but are actually complementary. To treat Kidney deficiency, one must base treatment on Yin and Blood; Blood moistens and tends to descend; in deficiency, it may ascend improperly, so it should be astringed to descend. To treat Spleen deficiency, one must base treatment on Yang Qi; Qi warms and tends to ascend; in deficiency, it may sink improperly, so it should be lifted to ascend. Modern practitioners treating Xu Lao often use Si Wu Tang (Four Substance Decoction) added with Zhi Mu and Huang Bo, or Da Zao Wan (Great Creation Pill) with Gui Ban (Testudinis Carapax et Plastrum) and Huang Bo, creating a mass of cold, fishy, and turbid properties. Where does this leave the growing Qi of the Spleen and Stomach? This is not tonifying Qi and Blood but destroying them. Therefore, two methods were established to correct this flaw.
Yin deficiency with Fire hyperactivity, manifesting as cold skin, bone-steaming fever, poor appetite, profuse phlegm, cough, shortness of breath, fatigue, and irritability, is primarily treated with Xin Ding Zheng Yin Li Lao Tang (Newly Formulated Rescue Yin Regulate Labor Decoction).

This discussion and these two formulas were composed by the author in his later years. Although both tonify the Kidney and Spleen, they differ from the previous two formulas for Wu Lao involving Spleen and Kidney. They are treasured within our family and have not been previously published. Note by Zu Yi.
