一位书生患有盗汗症，每晚被子都被汗水浸湿好几层，打开帐子时，热气像雾一样向上蒸腾。我用当归六黄汤，加减变化几十剂，症状仅减轻了二三成，未能完全痊愈。诊察其六脉皆伏沉，这是极度虚弱的表现，于是加入七分人参，将黄芩用量增至三倍，再用童便煎煮三分附子，服用一剂后热退，汗止了一半，再服用后汗证也痊愈了。
精，是血的精华部分。《内经》说：“阳气平和，阴气固秘，精神才能正常；阴阳分离决裂，精神就会枯竭。”由于肾水虚衰，心火妄动，导致肾水不得安宁，从而不自主地遗泄。追溯其原因，主要有四种，为什么呢？
第一种是有梦交而遗精的，这是由于火动水沸，神志驰散而精液外泄，这是心神不守、欲望混乱所致，治疗方法应当以养心宁神为主，辅以益肾固窍；
第二种是由于下元虚弱，精神涣散溢泄而遗精的，这是肾气衰败不能固摄，精关失约，导致精液妄泄，治疗方法应当以补肾为主，辅以涩精止遗；
第三种是年轻力壮、元气充沛之人，长期节制房事，导致经络壅滞而遗精的，这是因为久旷之后精满自溢，只要让其泄出即可自然平复；
第四种是情欲萌动于心中，愿望未遂而遗精的，只需疏导其情欲即可自行停止，甚至不需要用药。
这四种情况中，唯有梦遗最为严重，因为既劳损心神又耗脱精液，痰火产生的机理，大多肇始于此，难道可以轻视看待吗？
圣人说，营气的精华部分，化生为精，聚集在命门。命门，是精血汇聚的地方。《内经》说：“男子十六岁时阳精上升，大约积累到一升二合，加以调养充实，可以达到三升；若损耗丧失，则不足一升。”说精是峻补之物，是因为精非血不能化生；说精是宝物，是因为精非气不能滋养。所以血盛则精长，气聚则精盈。这就好比海水的潮汐，也是由天地间阳气的鼓舞所致。因此，气、血、精三者，同源而异流，殊途而同归。《期嗣真诠》也说：精就像从朱砂中提取汞一样。法度是将朱砂放入鼎中，用火逼迫它，汞才会出来。夫妇交媾时，必然触动淫火，精液才会泄出。所以道家炼丹的人用汞铅来比喻精血，正是这个意思。然而精确实是营气的精华，但肾中的一滴真水，则是生于无极、长于太极，有形有质，难以形成却容易亏损，男女都有这种物质，所以男女纵欲过度，都能导致水亏而成阴虚火动的病症，其中的道理由此可见。所谓“十六岁精满”，恐怕是由饮食厚味的津液所转化而成的浊阴澄秘之物，又借助肺气的输布归于肾，就像酒搀水一样，必须依靠本浮的气味，才能充盈。所以富贵之人，虽然放纵淫欲酒色，未必全都患上痰火病，这是因为日常食用荤腥浓味食物，所以化生的精液也多，即使频繁泄精也不会立刻感到口渴。至于天一之真精，则是父母先天所成，是人身的至宝，岂能频繁妄泄呢？如果没有浓味精液的帮助，就像酒的真正酒精成分，怎能频繁耗费妄加消耗呢？如果平民百姓像富贵人那样纵欲，得病的也就很少见了。况且梦遗这一证候，由于纵欲劳神，导致坎离不交，水火未济，劳神夺精，心不能御神，肾不能摄精，心神荡溢，因此一梦而遗精，其严重程度超过其他遗精的原因就在于此。治疗方法应当泻南方（心火），补北方（肾水），益真火，壮真水，这样才能掌握病情的奥妙。

A scholar suffered from night sweats. Every night, his blankets were soaked through several layers. When the bed curtain was opened, the heat rose like fog. I prescribed Danggui Liuhuang Tang (Angelica Sinensis Six-Huang Decoction), making dozens of modifications over many doses. The symptoms reduced by only two or three parts out of ten, without full recovery. Upon examining the six pulses, they were all deep and hidden (Fu Chen), indicating extreme deficiency. I added 0.7 qian of Renshen (Ginseng Radix et Rhizoma) and increased Huangqin (Scutellariae Radix) to three times the original dose. Additionally, I decocted 0.3 qian of Fuzi (Aconiti Lateralis Radix Praeparata) using urine from a healthy child (Tongbian). After one dose, the fever subsided, and sweating stopped by half. After another dose, the sweating disorder was also cured.
Jing (Essence) is the purest essence of Blood. The Classics state: "When Yang is balanced and Yin is secure, Spirit and Essence are governed; when Yin and Yang separate and rupture, Spirit and Essence are exhausted." Due to the deficiency and decline of Kidney Water, Heart Fire moves recklessly, causing Kidney Water to lose its tranquility. Consequently, Jing leaks without restraint. Tracing back to the root causes, there are four types. Why?
First, there is emission accompanied by dreams (Meng Yi). This is caused by Fire moving and Water boiling, with the Spirit wandering and Essence leaking. This results from the Mind failing to cultivate virtue and chaotic desires. The treatment method should prioritize nourishing the Heart and calming the Spirit, assisted by tonifying the Kidney and securing the orifices.
Second, there is emission due to weakness in the Lower Yuan, where Spirit and Essence overflow. This is caused by Kidney decline failing to grasp and hold, and the Jade Gate (Jade Gate/Orifice of Essence) lacking restraint, leading to reckless leakage of Essence. The treatment method should prioritize tonifying the Kidney, assisted by astringing Essence.
Third, there is emission in young individuals with robust Qi and vitality, resulting from long-term abstinence from sexual intercourse, which causes stagnation in the meridians. This is due to fullness of Essence after prolonged abstinence, leading to natural overflow. It only needs to be allowed to discharge to return to balance naturally.
Fourth, there is emission caused by emotional arousal within, where desires are unfulfilled. Simply allowing the emotions to flow will stop it spontaneously; medication may not even be necessary.
Among these four, Meng Yi (Dream Emission) is the most severe. Because it involves both mental exertion and depletion of Essence, the mechanism of Phlegm-Fire often originates here. How can it be viewed lightly?
The Sages say that the purest part of Ying Qi (Nutritive Qi) transforms into Jing (Essence) and gathers in the Mingmen (Gate of Life). Mingmen is the mansion of Jing and Blood. The Classics state: "At age sixteen (two eight-years), the Yang Jing rises, accumulating approximately one sheng and two he. If nurtured and filled, it can reach three sheng; if damaged and lost, it falls below one sheng." To say Jing is potent is because Jing cannot transform without Blood. To say Jing is precious is because Jing cannot be nourished without Qi. Therefore, abundant Blood leads to abundant Jing, and gathered Qi leads to full Jing. This is akin to ocean tides, driven by the Yang Qi between Heaven and Earth. Thus, Qi, Blood, and Jing share the same source but have different flows, taking different paths but arriving at the same destination. *Qisi Zhenquan* also states: Jing is like extracting Mercury from Cinnabar. The method places Cinnabar in a tripod and forces it with fire, causing the Mercury to emerge. In marital intercourse, lustful Fire must move for Essence to leak. Thus, Daoist alchemists use Mercury and Lead as metaphors for Jing and Blood, reflecting this meaning. However, although Jing is indeed the purest part of Ying Qi, the single drop of True Water in the Kidney is born from Wuji (Limitless) and generated from Taiji (Supreme Ultimate). It has form and substance, is difficult to form but easy to lose. Both men and women possess this substance. Therefore, excessive desire in either sex can lead to Water deficiency and Yin deficiency with Fire hyperactivity, revealing the underlying principle. The statement "Jing is full at age sixteen" likely refers to turbid yin substances transformed from rich dietary fluids, clarified and stored, then transported by Lung Qi back to the Kidney. Like wine mixed with water, it requires the floating aroma and taste to become full. Thus, wealthy people, despite indulging in lust, alcohol, and color, do not necessarily develop Phlegm-Fire diseases. This is because their daily diet of rich meats provides ample nutrients, so even frequent ejaculation does not immediately cause thirst. As for Tianyi's True Jing (Primordial Essence), it is formed by parents' congenital essence and is the supreme treasure of the human body. Can it be frequently and recklessly leaked? Without the assistance of rich dietary essences, like the true alcohol in wine, how can it be frequently wasted and consumed? If commoners indulge like the wealthy, few would remain free of disease. Moreover, regarding the syndrome of Meng Yi (Dream Emission), excessive desire and mental labor cause Kan (Water/Kidney) and Li (Fire/Heart) to fail to interact, and Water and Fire to remain unbalanced. Mental labor steals Essence; the Heart fails to govern the Spirit; the Kidney fails to grasp Essence. The Spirit wanders wildly, leading to emission upon dreaming. Its severity surpasses other forms of emission for this reason. The treatment method should drain the South (Heart Fire), tonify the North (Kidney Water), benefit True Fire, and strengthen True Water, thereby grasping the profound nature of the condition.
