丹溪先生认为，人的阳气常常有余，而阴气常常不足，因此应当经常滋补阴气，使阴与阳保持平衡，这样就能实现“水升火降”（肾水上济心火，心火下温肾水）的状态。人唯有以肾气为根本，所以这个方剂专门用于滋培肾水。这是遵循丹溪这位前贤的法则，顺应天道。
黄柏（去除外皮，用盐和酒炒制）、知母（去除外皮，用盐和酒炒制）、龟板（去除边缘筋膜，用酥油炙烤，各二两，需洁净）、怀庆熟地黄（用酒蒸九次后晒干）、天门冬（去除心，各二两）、干姜（炒至紫色，三钱；冬季可用五钱）。
以上药物研成细末，用炼蜜制成如梧桐子大小的丸药。每次服用八九十丸，空腹时用炒盐汤送服；冬季可用温酒送服，不饮酒者也可用清米汤送服。
若需调理脾胃，可加入山药、白术、白茯苓（各二两）、陈皮（一两）。
若需固精，可加入牡蛎（用童便淬制七钱）、山茱萸肉（二两）、白术（七钱）。
若需壮腰膝，可加入虎胫骨（用酥油炙烤）、汉防己（用酒洗）、牛膝（去除芦头，用酒洗，各一两）。
（经验之谈）这些滋补诸方是士大夫君子日常延年益寿、接续真元以达到期颐之年（百岁）或成仙境界的良方。
本方专门培养元气，延年益嗣，壮旺阳光（命门之火），温煦坎水（肾水），使离火（心火）下降，达到天地交泰的境界。对于虚劳且房事过度的人（表现为五心烦热），服用此方神效；普通人四十岁以后也尤其适宜常服，以接续补益真元，达到高寿。
紫河车（胎盘）一具，最好取初生男婴的胎盘，如果没有，强壮妇人的也可以。先用新鲜的米泔水将紫河车轻轻展开，换洗米泔水五次，注意不要损伤筋膜，这保留了初结时的真气。只洗净草屑，轻手去除，放入竹器中，在长流水中浸泡一刻钟以汲取生气。取出后，用小瓦盆盛放，置于没有底座的甑内蒸制，从卯时到辰时开始蒸，直到申时到酉时停止，用文火和武火缓缓蒸至极烂如糊状。取出后，先倒出自然渗出的汁液混入药末中略加调和，这是天元的正气汁。将紫河车放入石臼中，用木杵捣一千下，呈糊状，与前药汁药末一同混合，再捣千余杵。集众人之力制成丸药，这是保全天元真气的方法，以人补人最为奇妙，世人很少知晓。医生用火焙或酒煮，又去除筋膜，是大错特错；又加入龟板，更是错误，故特意阐明指出。
浓川黄柏（去除粗皮，酒炒一两）、川杜仲（去除粗皮，酥炙断丝一两五钱）、川牛膝（酒浸去芦一两五钱）、黄芪（酒浸一两半）、麦门冬（去心一两五钱，以上四味另用酒煮烂捣膏）、陈皮（去白净七钱半）、白术（去芦炒一两）、五味子（去梗七钱）、小茴香（炒七钱）、枸杞（去梗一两）、干姜（炮黑二钱）、侧柏叶（采取嫩枝隔纸炒干二两）。
若骨蒸潮热，加牡丹皮（去心）、地骨皮（去心）、知母（去皮，各一两，酒炒）。
若血虚，加当归、地黄（用量加倍）。
若气虚，加人参、黄芪（蜜炙，各一两）。
妇人服用，去掉黄柏，加入川芎、香附、细实条芩（均酒炒，各一两）。
以上药物各自精心挑选精制，称量干净后研成粉末，不可接触铁器。使用前蒸熟的紫河车捣烂，连同汁液一起和药末制成丸药。如果紫河车肥大，可适当增加药末的量，不必使用蜂蜜。丸药如梧桐子大，每次服用一百丸，空腹用米汤送服。有病者一日两次服用。按此方比古方使用效果更佳。若是禀赋虚弱或过早、过度耗损精气的人，尤其适宜使用。
Danxi stated that in humans, Yang is often in excess while Yin is often deficient; therefore, one should frequently tonify Yin to ensure Yin and Yang are balanced, thereby facilitating the ascent of Water (Kidney) and descent of Fire (Heart). Humans must take Kidney Qi as their foundation. Thus, this formula specifically nourishes and cultivates Kidney Water, following the method of Danxi, a former sage, which aligns with the Way of Heaven.
Cortex Phellodendri Amurensis (Huangbai, 黄柏) [peeled, stir-fried with salt and wine], Rhizoma Anemarrhenae Asphodeloidis (Zhimu, 知母) [peeled, stir-fried with salt and wine], Carapax et Plastrum Testudinis (Guiban, 龟板) [edges and sinews removed, roasted with suet, each 2 liang, cleaned], Radix Rehmanniae Praeparata (Shudihuang, 熟地黄) from Huaiqing [steamed with wine nine times, then sun-dried], Herba Asparagi Cochinchinensis (Tianmendong, 天门冬) [heart removed, each 2 liang], Rhizoma Zingiberis Recens (Ganjiang, 干姜) [stir-fried until purple, 3 qian; 5 qian in winter].
Grind the above ingredients into fine powder. Form pills using refined honey, sized like paulownia seeds. Take 80-90 pills per dose on an empty stomach, washed down with decoction of stir-fried salt. In winter, warm wine may be used; for those who do not drink alcohol, clear rice soup is also acceptable.
To regulate Spleen and Stomach, add Rhizoma Dioscoreae Hypoglaucae (Shanyao, 山药), Rhizoma Atractylodis Macrocephalae (Baizhu, 白术), Poria Cocos (Baifuling, 白茯苓) [each 2 liang], and Pericarpium Citri Reticulatae (Chenpi, 陈皮) [1 liang].
To consolidate essence, add Concha Ostreae (Muli, 牡蛎) [quenched in child's urine, 7 qian], Fructus Corni Officinalis (Shanzhuyu, 山茱萸) [flesh, 2 liang], and Rhizoma Atractylodis Macrocephalae (Baizhu, 白术) [7 qian].
To strengthen waist and knees, add Os Tigris (Hu Jinggu, 虎胫骨) [roasted with suet], Radix Stephaniae Tetrandrae (Hanfangji, 汉防己) [washed with wine], and Radix Achyranthis Bidentatae (Niuxi, 牛膝) [radicle removed, washed with wine, each 1 liang].
(Experience) These nourishing formulas are suitable for scholars and gentlemen for daily longevity, extending life, and replenishing true Yuan to reach the age of a century or even immortality.
This formula specifically cultivates Original Qi, extends life, aids offspring, strengthens Yang Light (Mingmen Fire), warms Kan Water (Kidney Water), and descends Li Fire (Heart Fire), achieving the harmonious interaction of Heaven and Earth. It is particularly effective for those with deficiency-wasting syndromes due to excessive sexual activity, presenting with five-palm heat. Ordinary people over forty years old should also take it regularly to replenish True Yuan and achieve high longevity.
Placenta Humanus (Ziheche, 紫河车): One placenta, preferably from a first-born male infant; if unavailable, from a robust woman is also good. First, gently unfold the placenta with fresh rice wash water, rinsing five times with rice wash water without damaging the fascia, preserving the primordial Qi formed at conception. Cleanly remove any grass debris by hand. Place in a bamboo vessel and soak in running water for one quarter of an hour to absorb vital energy. Transfer to a small earthenware pot and steam inside a steamer without a bottom base. Start steaming from Mao-Chen hours (5:00-9:00 AM) until Shen-You hours (3:00-7:00 PM), using gentle and strong fire alternately until extremely soft and paste-like. Remove and pour out the natural juice into the herbal powder, mixing slightly; this is the juice of Heavenly Primal Righteous Qi. Place the placenta in a stone mortar and pound with a wooden pestle for one thousand strokes until paste-like. Mix thoroughly with the previous herbal juice and powder, pounding for another thousand strokes. Collect hands to form pills. This preserves Heavenly Primal Qi; using human to supplement human is most excellent. Few know this. Doctors mistakenly use fire-baking or wine-boiling, remove fascia, and erroneously add Carapax et Plastrum Testudinis. Therefore, I specifically clarify this.
Cortex Phellodendri Amurensis (Nongchuan Huangbai, 浓川黄柏) [remove coarse bark, stir-fried with wine, 1 liang], Cortex Eucommiae Ulmoidis (Chuanduzhong, 川杜仲) [remove coarse bark, roasted with suet until fibers break, 1.5 liang], Radix Achyranthis Bidentatae (Chuanniuxi, 川牛膝) [soaked in wine, radicle removed, 1.5 liang], Radix Astragali Membranacei (Huangqi, 黄芪) [soaked in wine, 1.5 liang], Flos Liliiorii (Maimendong, 麦门冬) [heart removed, 1.5 liang] (the above four ingredients are separately boiled in wine until soft and mashed into paste), Pericarpium Citri Reticulatae (Chenpi, 陈皮) [white pith removed, clean, 7.5 qian], Rhizoma Atractylodis Macrocephalae (Baizhu, 白术) [radicle removed, stir-fried, 1 liang], Fructus Schisandrae Chinensis (Wuweizi, 五味子) [stalks removed, 7 qian], Fructus Foeniculi Vulgaris (Xiaohuixiang, 小茴香) [stir-fried, 7 qian], Fructus Lycii Chinensis (Gouqi, 枸杞) [stalks removed, 1 liang], Rhizoma Zingiberis Preparatum (Ganjiang, 干姜) [charred, 2 qian), Folium Platycladi Orientalis (Ceboye, 侧柏叶) [tender branches taken, dried between papers after stir-frying, 2 liang].
For bone-steaming fever, add Cortex Moutan Radicis (Mudanpi, 牡丹皮) [heart removed], Cortex Lycii Radicis (Digupi, 地骨皮) [heart removed], and Rhizoma Anemarrhenae Asphodeloidis (Zhimu, 知母) [peeled, each 1 liang, stir-fried with wine].
For Blood deficiency, add Radix Angelicae Sinensis (Danggui, 当归) and Radix Rehmanniae Glutinosae (Dihuang, 地黄) [double the amount].
For Qi deficiency, add Radix Ginseng (Renshen, 人参) and Radix Astragali Membranacei (Huangqi, 黄芪) [honey-roasted, each 1 liang].
For women, remove Cortex Phellodendri Amurensis and add Radix Ligustici Chuanxiong (Chuanxiong, 川芎), Rhizoma Cyperi Rotundi (Xiangfu, 香附), and Radix Scutellariae Baicalensis (Tiaoxinhuangqin, 条芩) [all stir-fried with wine, each 1 liang].
Select and refine each herb carefully. Weigh cleanly and grind into powder. Do not use iron vessels. Use the previously steamed and pounded Placenta Humanus along with its juice to mix with the powder and form pills. If the placenta is large and fleshy, increase the amount of herbal powder accordingly; honey is not necessary. Form pills sized like paulownia seeds. Take 100 pills per dose on an empty stomach with rice soup. For those with illness, take twice daily. This formula is more effective than ancient prescriptions. It is especially suitable for those with weak constitution or those who have depleted their essence too early or excessively.
