论肾虚感寒 水亏夜热
天师曰∶阴治者，病症乃阴气不足，而阴邪又犯之也。如肾水虚寒，又感寒者；或肾水亏竭，夜热
昼寒是也。此等病，若认作阳症治之，则口渴而热益炽，必致消尽阴水，吐痰如絮，咳嗽不已，声哑声嘶，
变成痨瘵。法当峻补其阴。则阴水足而火焰自消，骨髓清泰，上热余火俱归乌有矣。方用熟地一两，山茱
萸五钱，麦冬五钱，北五味五钱，元参三
钱，地骨皮三钱，丹皮一钱，沙参五钱，白芥子一钱，芡实五钱，车前子一钱，桑叶七片，水
煎服。（〔批〕安火至圣汤。）此方妙在全用纯阴之品，一直竟进肾宫，滋其匮乏，则焦急之形，不上
焰于口舌皮毛之际∶又加元参、地骨皮、沙参、丹皮之品，少清其骨髓中之内热，自然阴长阳消，不治
阳而自安也，又何必更加柴胡以散之，而邪始去哉。此方乃治阴火自动者神效。若阴寒无火者，又不宜
用此方。当用肉桂一钱，附子一钱，熟地一两，山茱萸四钱，白术三钱，人参三钱，柴胡五分，水煎

症矣。愿人加意于水中补火，更于水中去邪也。
张公曰∶妙绝之论，发千古所未发，何以再赞高深。然尚有一方以参之。前症乃阴虚火动也，用六
味汤似亦相宜；后症乃阴寒无火也，八味汤似亦可用，然而终不及天师二方。盖治阴之内，即留以治阳；
而治阳之中，即藏于补阴也。有贫不能用人参者，用予后方可也。
华君曰∶同传予法无异。
陈士铎说：所谓“阴治法”，是指病症属于阴气不足，同时又有阴邪侵犯的情况。例如肾中水液虚寒，又感受了寒邪；或者肾水枯竭，出现夜间发热、白天发冷的症状。这类疾病，如果误认为是阳证来治疗，就会导致口渴且热势更加炽盛，最终必然耗竭体内的阴液，出现呕吐痰液如棉絮状、咳嗽不止、声音嘶哑等症状，进而演变成痨瘵（慢性消耗性疾病）。治疗方法应当大补其阴。这样阴液充足而虚火自然消除，骨髓清爽安宁，上部的余热和余火也就随之消失。方剂使用熟地黄一两，山茱萸五钱，麦冬五钱，北五味子五钱，玄参三钱，地骨皮三钱，牡丹皮一钱，沙参五钱，白芥子一钱，芡实五钱，车前子一钱，桑叶七片，加水煎服。（批注：安火至圣汤。）这个方子的妙处在于全用纯阴的药物，直接深入肾脏，滋补其亏缺，那么焦躁的症状就不会在口舌皮毛表面显现；再加上玄参、地骨皮、沙参、牡丹皮等药物，轻微清除骨髓中的内热，自然达到阴长阳消的效果，不需要专门治疗阳亢而身体自然安宁，又何必多加柴胡来发散，才能使邪气去除呢？此方是治疗阴火自动发作的神效方。如果是阴寒而无虚火的情况，就不宜使用此方。应当使用肉桂一钱，附子一钱，熟地黄一两，山茱萸四钱，白术三钱，人参三钱，柴胡五分，加水煎服。（批注：祛寒至圣丹。）这个方子的妙用在于将附子、肉桂这些祛寒的药物，加入到人参、熟地黄补阴的药物之中，使阳气得到阴液的制约，不至于奔越沸腾；稍微加入几分柴胡，阴邪自然消散，又何必纯用麻黄、桂枝之类的药物，烧尽真阴呢？况且肾中的火，必须依赖水才能产生。因为水不是邪水，而是真水。邪水可以侵犯心脏导致立即死亡，真水可以拯救心脏而延长寿命。大概阳气根源于阴，而真正的阴肾水，实际上是真阳君相之火的母亲。此方中加入熟地黄、山茱萸，正是这个意思。（批注：妙极了）担心人们不明白，所以特意阐述出来。如果只使用附子、肉桂来祛寒，未尝不有效。然而邪气去除后阴液也会消减，必然导致枯竭。如果治疗不得法，必定会出现亡阳的症状。希望大家在意于水中补火，更要在其中祛除邪气。
张公说：这是绝妙的论述，阐发了千古以来未曾发表的观点，我还有什么可再赞美高深的呢？然而还有一方可以参考。前面的症状是阴虚火动，使用六味丸似乎也适宜；后面的症状是阴寒无火，八味丸似乎也可以使用，然而终究不及陈天师的两个方子。大概是在治疗阴的过程中，就留下了治疗阳的方法；而在治疗阳的过程中，就隐藏着补阴的道理。如果有贫穷不能用人参的人，可以使用予方的方法。
华君说：与传授给我的方法没有不同。
Chen Shiduo said: The so-called "Yin Treatment Method" refers to conditions where there is a deficiency of Yin Qi, accompanied by an invasion of Yin pathogens. For example, when the Kidney water is deficient and cold, and simultaneously exposed to cold pathogens; or when Kidney water is exhausted, resulting in night fever and daytime chills. Such diseases, if mistakenly treated as Yang syndromes, will lead to thirst and intensified heat, inevitably consuming all Yin fluids, causing vomiting of sputum like cotton floss, incessant coughing, hoarseness, and eventually evolving into Lao Zhai (chronic consumptive disease). The treatment method should be to vigorously tonify Yin. When Yin fluids are sufficient, the deficient fire will naturally subside, the bone marrow will become clear and peaceful, and the residual heat and fire above will vanish. The prescription uses Shu Di Huang (Rehmanniae Radix Praeparata) 1 liang, Shan Zhu Yu (Corni Fructus) 5 qian, Mai Dong (Ophiopogonis Tuber) 5 qian, Bei Wu Wei Zi (Schisandrae Chinensis Fructus) 5 qian, Yuan Shen (Scrophulariae Radix) 3 qian, Di Gu Pi (Lycii Cortex) 3 qian, Dan Pi (Moutan Cortex) 1 qian, Sha Shen (Glehniae Radix) 5 qian, Bai Jie Zi (Sinapis Semen) 1 qian, Qian Shi (Euryales Semen) 5 qian, Che Qian Zi (Plantaginis Semen) 1 qian, Sang Ye (Mori Folium) 7 leaves, decocted in water and taken orally. (Commentary: An Huo Zhi Sheng Tang [Supreme Sage Decoction for Calming Ministerial Fire].) The brilliance of this formula lies in its exclusive use of pure Yin herbs, which penetrate directly into the Kidney palace to nourish deficiencies. Thus, the anxious symptoms will not flare up on the surface of the mouth, tongue, skin, and hair. Furthermore, by adding Yuan Shen, Di Gu Pi, Sha Shen, and Dan Pi to slightly clear the internal heat within the bone marrow, Yin naturally grows while Yang declines. The body becomes peaceful without specifically treating Yang, so why add Chai Hu (Bupleuri Radix) to disperse, only for the pathogen to leave? This formula is highly effective for treating spontaneously arising Yin fire. However, it is not suitable for cases of Yin cold without fire. In such cases, one should use Rou Gui (Cinnamomi Cortex) 1 qian, Fu Zi (Aconiti Lateralis Radix Preparata) 1 qian, Shu Di Huang 1 liang, Shan Zhu Yu 4 qian, Bai Zhu (Atractylodis Macrocephalae Rhizoma) 3 qian, Ren Shen (Ginseng Radix) 3 qian, Chai Hu 5 fen, decocted in water and taken orally. (Commentary: Qu Han Zhi Sheng Dan [Supreme Sage Pill for Expelling Cold].) The ingenious application of this formula lies in combining cold-expelling herbs like Fu Zi and Rou Gui with Yin-tonifying herbs like Ren Shen and Shu Di Huang, allowing Yang to be controlled by Yin, preventing it from surging and boiling. Adding a small amount of Chai Hu allows Yin pathogens to dissipate naturally. Why use purely Ma Huang (Ephedrae Herba) and Gui Zhi (Cinnamomi Ramulus) to scorch away true Yin? Moreover, the fire in the Kidneys must arise from Water. This Water is not pathogenic water but True Water. Pathogenic water can invade the Heart leading to immediate death, whereas True Water can save the Heart and prolong life. Generally, Yang is rooted in Yin, and True Yin Kidney Water is truly the mother of True Yang Jun Xiang Fire (Monarch and Minister Fire). The addition of Shu Di Huang and Shan Yu in this formula embodies this principle. (Commentary: Extremely brilliant.) Fearing that people might not understand, I have elaborated on this. If one uses only Fu Zi and Rou Gui to expel cold, it may indeed be effective. However, after the pathogen is expelled, Yin will diminish, inevitably leading to exhaustion. If treated improperly, symptoms of Wang Yang (collapse of Yang) will surely occur. I hope people pay attention to tonifying fire within water and removing pathogens within water.
Mr. Zhang said: This is an extraordinarily brilliant discussion, revealing insights never expressed in millennia. How could I add further praise to its profundity? Nevertheless, there is another formula for reference. The former symptom is Yin deficiency with fire movement, for which Liu Wei Wan (Six-Ingredient Rehmannia Pill) seems appropriate; the latter symptom is Yin cold without fire, for which Ba Wei Wan (Eight-Ingredient Rehmannia Pill) seems usable. However, neither ultimately compares to Master Chen's two formulas. Essentially, within the treatment of Yin, methods for treating Yang are retained; and within the treatment of Yang, principles of tonifying Yin are hidden. For those too poor to afford Ren Shen, the method of my previous formula can be used.
Mr. Hua said: It is no different from the method transmitted to me.
