陈逊斋先生说：延寿丹方，是云间大宗伯董玄宰先生长期服用有效的方子。我的先父曾在门下受业于他，我有幸聆听先生的教诲，先生也接受了我的书法作品，深得运笔用腕的秘诀。侍奉陪伴久了，才获得这个方子。先生年事已高（至八十岁以上），服用此丹后，白发变黑，精神由衰弱转为旺盛，确实是祛除疾病、延长寿命的仙品。普通人往往缺乏恒心，吃一服药就想要见效。经书明确指出了“久服”二字，人们不明白其中道理，反而责怪药物无效，这是错误的。我辞官二十多年来，家境贫寒且年老，专心钻研医学（轩岐指黄帝与岐伯，代指中医），向名流请教，勤奋精进，连睡觉吃饭都忘记了。历经二十多年，才通晓《内经》的道理和阴阳之道。我在壬子年七十五岁时，因饥饱不均和劳累过度，得病几乎危及生命。于是寻找药材制作此丹。从壬子年八月初一开始服用，直到次年癸丑年重阳节登上雨花台，先于老朋友上山，不再像往年那样需要人搀扶，而且也不气喘了，心里感到非常惊奇，这才敬服此丹的神奇功效。我原先须发全白，现在头发全黑，胡须黑了一半；以前不能行走，现在能快步如飞。凡亲友都求取此方，我便发自内心地希望帮助他人长寿，于是刻印此书广泛传播，让天下人都能长寿。虽然药力如此神奇，但必须药力与德行并行不悖，才能万无一失。药品配方如下：
何首乌：以个大者为有效。取赤、白两种，用黑豆汁浸泡一夜，用竹刀刮去外皮，切成薄片，晒干。再用黑豆汁浸泡一夜。次日清晨，用柳木蒸笼、桑柴火蒸三炷香的时间。如此重复九次，务必记清不可增减剂量。晒干备用。其余群药共若干两，何首乌也用若干两。此药生精益血，黑发乌须，久服使人有子嗣，祛除疾病，延长寿命。
菟丝子：先淘洗去掉浮皮，再用清水淘洗挤掉沙泥五六次，取沉底的晒干。逐粒拣去杂质，选取坚实、呈腰子样、有丝状的。用无灰酒浸泡七天，放入蒸笼，蒸七炷香的时间，晒干。再另用酒浸泡一夜，入蒸笼蒸六炷香的时间，晒干。如此重复九次，记清后晒干磨成细末一斤。此品滋养肌肉，强壮阴气，补益卫气，辅助筋脉，更治疗茎中寒冷、精液自出、小便余沥不尽、腰膝软弱痿痹，增强体质，增添精气，使面色悦泽，增加食欲，久服益气力，黑须发。
豨莶草：五六月采集叶片，用长流水洗净晒干。与蜂蜜及无灰酒拌匀，拌潮一夜。次日清晨蒸三炷香的时间。如此重复九次，记清后晒干为细末一斤。此品驱除肝肾风气，治疗四肢麻痹、骨痿膝酸，治疗口眼歪斜，避免半身不遂，安五脏，生毛发。唐代张咏上表说：服用豨莶草百次，眼目清明，筋力轻健，多服须发乌黑，久服长生不老。
嫩桑叶：四月采集，杭州、湖州家园采摘的入药。到处野生的桑树叶子不入药用。取叶片，用长流水洗净，晒干。按照制豨莶草的方法九次炮制，取细末八两。此品能治五劳六极、羸瘦水肿、虚损。经云：蚕吃生丝织成经线，人吃生脂延年益寿。
女贞实：冬至日在乡村园林中，摘取腰子样黑色的果实，走肾经。坟墓上圆粒青色的为冬青子，不入药用。用布袋装好，剥去粗皮，酒浸一夜，蒸三炷香的时间，晒干为细末八两。此药黑发乌须，强筋力，安五脏，补中气，除百病，养精神，多服补血祛风，久服返老还童。
忍冬花：一名金银花，夜晚闭合白天开放，蕴含阴阳之义。四五月处处生长。采摘后阴干。按照豨莶草的方法九次炮制晒干，细末四两。此品壮骨筋，生精血，消除胀满，逐水健身延年。
川杜仲：以厚实者为佳。去掉粗皮，用青盐同姜汁拌润，炒至断丝，八两。此药益精气，坚筋骨，治疗脚中酸痛、不能踩地、色欲过度劳累、腰背挛痛强直，久服轻身耐老。
雄牛膝：怀庆府出产的最好。去掉根芦头净尽，肉质屈曲而不断裂，粗大肥厚者为雄；细短硬脆，屈曲易断者为母，不用。用酒拌晒八两。此品治疗寒湿痿痹、四肢拘挛、膝痛不可忍受、男子阴消、老人遗尿，续绝益精，利阴益体，黑发乌须。以上杜仲、牛膝炮制好后，暂不要磨成粉末。待何首乌八十四两，蒸过六次后，不用黑豆汁拌，单独用杜仲、牛膝二种，同何首乌一起拌蒸三次，晒三次，以达到九蒸的次数。
怀庆生地：取钉头鼠尾状，或原梗未入水弯曲成大枝状的为有效。掐如米粒大小，晒干为细末四两。
从菟丝子到生地共七十二两，何首乌赤白共七十二两。用四种膏子（旱莲草熬膏一斤，金樱子熬膏一斤，黑芝麻熬膏一斤，桑椹子熬膏一斤），同前药末一百四十四两，捣数千下为标准。如果膏不够，用白蜂蜜补充，捣润才足。
加减法：阴虚的人加熟地黄一斤，阳虚的人加附子四两，去掉地黄。下元虚亏，加虎骨一斤。麻木的人加明天麻、当归八两。头晕的人加玄参、明天麻各八两。目昏的人加黄甘菊花、枸杞子各四两。肥胖人多湿痰者，加半夏、陈皮各八两。群药占一半数量，何首乌占一半。这是灵活变化的方法。
神农以前，人都能活到几千岁。尝百草之后，逐渐减至百岁、数十岁以至几岁。我认为草根树皮，毒性进入脏腑，怎能借七情六欲的伤害，来为老农解嘲呢？当我儿子生病时，医生的鞋子堆满了门口，都说必死无疑。最后逊斋先生到来，唯独说必不死。随即开方，人参、附子用到数两，看方子的人都感到惊骇。我也不敢相信。我儿子相信并服用，果然有了起色。然而在那生死呼吸之间，众医摇头吐舌不顾惜的情况，先生笑着说：“这是生机啊。”他的说法很痛快，道理很微妙。究其十年，枕上之人，竟有一天霍然起身。这是先生的功劳。医生如同医生，药物如同药物，有的用来致死，有的用来救命，关键在于如何使用。先生不急于治病，而急于救治病人。医生的医德，药物的效用，已经具备了仓公、扁鹊的肩膀（指高超医术）。每次读列传，怀疑太史公喜欢讲奇谈怪论，现在对先生深信不疑。然而先生大概是得道之人。年七十有八，童颜红润，白髭再次变黑。自从辞官以来，每次相见都觉得他年轻了一些，这难道不是把凡胎换成了仙骨吗？
顷刻间延寿丹方行世，种种炮制方法，都不是各家所知的。利济之功，等同于造化。况且我看见将不起之症能在床褥间救起，举世无病的人在闲暇时日服用，怎么不能在晚年接近神农以前的寿命呢？年家弟何亮功偶然笔录。
客人问我：药能杀人吗？我说：药怎么能杀人，杀人的是医生。客人说：有这样的事吗？我说：请听我说。我邀请健身，又本性不喜欢吃药，常藏秘方，储备良药以应对世间多病且嗜药的人，我心里很高兴。内侄何大椿，是次德的长子。负有奇才，患有奇病，医生说治不好，众人异口同声，并且定了日期，有的说三天，有的说五天，有的说七天，十天全部去世。每次我和次德相对，无法解除他的愁苦。只有陈子逊斋，诊脉一次，谈笑风生，说等待命令起来行动。后来三天没死，五天没死，七天十天也没死，现在步履如风，比未病时更加壮健。才相信逊斋先生真有洞见垣外的高超医术。逊斋归隐白门，临池之余，留心方药，他所获得的董玄宰宗伯延寿丹，自己服用有效，就刻印方子示人。虽然专业并非岐黄，但深究太素之精妙，超过岐黄。人们每有请托，没有不死而复生的。因此想到各位医生在用药之道上互相竞争，即使是起剪、颇牧这样的名将也不过如此。逊斋独自注重培养元气，我私下为次德的喜悦而喜悦，为次德的感激而感激。危险的病症可以回生，那么延寿之丹，可以永年无疑。我希望人们急切服用不要错过。这也是我藏秘方、蓄善药的婆心，借此回答客人的问题并发表言论。年家弟方享咸题写。我另外著有《长寿谱》、《救命针》两本书，凡是年老体虚弱有病的人，亟宜熟悉。
Mr. Chen Xunzhai said: The Yan Shou Dan (Longevity Pill) formula is a prescription that Mr. Dong Xuanzai, Grand Secretary of Yunjian, had long taken with effect. My late father studied under him, and I had the honor of listening to his teachings. He also accepted my calligraphy works, mastering the secret of wrist movement. After accompanying him for a long time, I finally obtained this formula. Mr. Dong was in his eighties; after taking this pill, his white hair turned black, and his spirit recovered from weakness to vigor. It is indeed a celestial product for eliminating disease and prolonging life. Ordinary people often lack perseverance, expecting results after just one dose. The classics explicitly state "long-term use" (Jiu Fu). People fail to understand this and wrongly blame the medicine for being ineffective. For over twenty years since resigning from office, living in poverty and old age, I devoted myself to studying Traditional Chinese Medicine (Xuan Qi refers to the Yellow Emperor and Qibo, representing TCM), seeking advice from famous scholars, working diligently and advancing, forgetting sleep and meals. After more than twenty years, I finally comprehended the principles of the *Neijing* (Inner Canon) and the Way of Yin and Yang. In the Renzi year, at the age of seventy-five, due to irregular eating and overwork, I fell critically ill. Thus, I sought medicinal materials to prepare this pill. Starting from the first day of the eighth month of the Renzi year, I took it until the Double Ninth Festival of the following Guichou year. I climbed Yuhua Terrace before my old friends, no longer needing support as in previous years, and without shortness of breath. I was deeply surprised and came to revere the miraculous efficacy of this pill. My beard and hair were previously all white; now my hair is completely black, and half of my beard is black. Previously unable to walk, I can now walk swiftly. Relatives and friends all requested this formula, so I sincerely wished to help others achieve longevity, having it printed and widely disseminated so that everyone in the world could live long. Although the medicinal power is thus, it must be combined with virtue to ensure complete safety. The ingredients are as follows:
Polygonum multiflorum (He Shou Wu): Large-sized roots are effective. Take both red and white varieties, soak overnight in black soybean juice, scrape off the skin with a bamboo knife, slice thinly, and dry in the sun. Soak again overnight in black soybean juice. The next morning, steam for the duration of three incense sticks using a willow wood steamer and mulberry wood fire. Repeat this process nine times, ensuring precision without adding or reducing. Dry in the sun for later use. The other herbs total a certain amount, and Polygonum multiflorum is used in a corresponding amount. This herb generates essence and nourishes blood, darkens hair and beard, promotes fertility with long-term use, eliminates disease, and prolongs life.
Cuscuta chinensis (Tu Si Zi): First wash away floating skins, then rinse with clear water several times to remove sand and mud, selecting the settled parts for drying. Pick out impurities grain by grain, selecting those that are solid, kidney-shaped, and fibrous. Soak in unadulterated wine for seven days, then steam for seven incense stick durations, and dry. Soak again overnight in fresh wine, steam for six incense stick durations, and dry. Repeat nine times, record carefully, dry, and grind into one jin of fine powder. This herb nourishes muscles, strengthens yin, supplements defensive qi (Wei Qi), assists tendons and vessels, treats coldness in the penis, spontaneous emission of semen, dribbling urine, weak and flaccid waist and knees, enhances constitution, adds essence, improves complexion, increases appetite, boosts energy with long-term use, and darkens beard and hair.
Siegesbeckia orientalis (Xi Xian Cao): Harvest leaves in May and June, wash clean with running water, and dry. Mix evenly with honey and unadulterated wine, moisten overnight. Steam the next morning for three incense stick durations. Repeat nine times, record carefully, dry, and grind into one jin of fine powder. This herb expels wind-dampness from the liver and kidneys, treats limb numbness and paralysis, bone atrophy and knee soreness, facial paralysis (mouth and eye deviation), prevents hemiplegia, calms the five zang organs, promotes hair growth. Tang Dynasty's Zhang Yong submitted a memorial stating: Taking Siegesbeckia hundred times clarifies eyesight and lightens physical strength; frequent use turns hair and beard black; long-term use ensures immortality.
Mulberrae Folium (Nang Sang Ye): Harvest in April; leaves from gardens in Hangzhou and Huzhou are used for medicine. Wild mulberry leaves everywhere are not used. Take leaves, wash clean with running water, and dry. Process nine times according to the method for Siegesbeckia, obtaining eight liang of fine powder. This herb treats five labors and six extremes, emaciation and edema, deficiency and damage. The classics state: Silkworms eat raw silk to weave warp threads; humans consume raw fat to prolong life.
Ligustrum lucidum (Nu Zhen Shi): On the Winter Solstice, pick black, kidney-shaped fruits from rural gardens, which enter the Kidney meridian. Round, green berries on tombs are Ligustrum japonicum (Dong Qing Zi) and are not used for medicine. Place in a cloth bag, peel off coarse skin, soak overnight in wine, steam for three incense stick durations, dry, and grind into eight liang of fine powder. This herb darkens hair and beard, strengthens tendons and bones, calms the five zang organs, supplements middle jiao qi, eliminates hundred diseases, nourishes spirit, benefits blood and expels wind with frequent use, and reverses aging with long-term use.
Lonicerae Japonicae Flos (Ren Dong Hua): Also known as Lonicerae Japonicae Flos (Jin Yin Hua). It closes at night and opens during the day, embodying the meaning of yin and yang. Grows everywhere in April and May. Pick and dry in shade. Process nine times according to the Siegesbeckia method, dry, and obtain four liang of fine powder. This herb strengthens bones and tendons, generates essence and blood, removes distension, drives out water, benefits health, and prolongs life.
Eucommiae Cortex (Chuan Du Zhong): Thick bark is preferred. Remove coarse skin, mix with green salt and ginger juice to moisten, stir-fry until fibers break, eight liang. This herb benefits essence and qi, strengthens bones and tendons, treats soreness and pain in feet making walking difficult, sexual exhaustion, spasmodic and stiff pain in the lower back, and promotes lightness and anti-aging with long-term use.
Achyranthis Bidentatae Radix (Xiong Niu Xi): Best produced in Huaiqing Prefecture. Remove root rhizomes cleanly. Flesh that bends but does not break, thick and plump, is male; thin, short, hard, brittle, bending easily and breaking is female, which is not used. Mix with wine and dry, eight liang. This herb treats cold-damp bi syndrome and flaccidity, limb contracture, unbearable knee pain, male genital atrophy, elderly urinary incontinence, reconnects severed tissues, benefits essence, promotes yin and body, and darkens beard and hair. After processing Eucommia and Achyranthes, do not grind into powder yet. Wait until eighty-four liang of Polygonum multiflorum have been steamed six times. Do not use black soybean juice for mixing; instead, mix the two herbs (Eucommia and Achyranthes) with Polygonum multiflorum, steam three times, and dry three times, totaling nine steaming cycles.
Rehmanniae Radix (Huai Qing Sheng Di): Roots shaped like nail heads and rat tails, or original stems that did not enter water and grew into large branches, are effective. Pinch into rice-grain sized pieces, dry, and grind into four liang of fine powder.
From Cuscuta to Rehmannia, the total is seventy-two liang. Red and white Polygonum multiflorum totals seventy-two liang. Use four pastes: Ecliptae Herba paste (Han Lian Cao) one jin, Rubi Fructus (Jin Ying Zi) paste one jin, Sesami Nigris Semen (Hei Zhi Ma) paste one jin, and Mori Fructus (Sang Shen Zi) paste one jin. Mix with the aforementioned one hundred forty-four liang of herb powders, pound for thousands of strikes as a standard. If paste is insufficient, add white honey to supplement, pounding until moist and sufficient.
Modification Method: For yin deficiency, add Prepared Rehmannia Root (Shu Di Huang) one jin; for yang deficiency, add Aconitum Lateralis Radix Praeparata (Fu Zi) four liang, removing Rehmannia. For lower yuan deficiency, add Panther Bone (Hu Gu) one jin. For numbness, add Gastrodia Rhizome (Tian Ma) and Angelicae Sinensis Radix (Dang Gui) eight liang. For dizziness, add Scrophulariae Radix (Xuan Shen) and Gastrodia Rhizome (Tian Ma) eight liang each. For blurred vision, add Chrysanthemi Flos (Huang Ju Hua) and Lycii Fructus (Gou Qi Zi) four liang each. For obese individuals with excessive damp-phlegm, add Pinelliae Rhizoma (Ban Xia) and Citri Reticulatae Pericarpium (Chen Pi) eight liang each. The group of herbs constitutes half the quantity, and Polygonum multiflorum constitutes half. This is the flexible method.
Before Shennong, people lived for thousands of years. After tasting herbs, lifespans gradually decreased to a hundred years, tens of years, down to a few years. I believe that herbal roots and barks, entering the viscera with toxicity, cannot explain aging merely through the injury of seven emotions and six desires, mocking the old farmer. When my son was ill, doctors' shoes filled the doorway, all claiming he would surely die. Finally, Mr. Xunzhai arrived, uniquely stating he would surely survive. He immediately prescribed a formula with Ginseng Radix et Rhizoma (Ren Shen) and Aconitum Lateralis Radix Praeparata (Fu Zi) reaching several liang. Those who saw the formula were shocked. I dared not believe it either. My son believed and took it, and indeed showed improvement. However, in those critical moments of life and death, while other doctors shook their heads and looked away, Mr. Xunzhai smiled and said, "This is the sign of vitality." His explanation was satisfying, and the principle subtle. Investigating over ten years, the person on the pillow suddenly rose in a day. This was Mr. Xunzhai's merit. Doctors are doctors, medicines are medicines; some are used to cause death, some to save lives, depending on how they are used. Mr. Xunzhai did not rush to treat the disease but rushed to save the patient. The medical ethics of doctors and the efficacy of medicines have reached the level of Cang Gong and Bian Que. Reading biographies, I suspected Sima Qian liked strange tales, but now I believe in Mr. Xunzhai. He is likely a person who has attained the Dao. At seventy-eight, he has a youthful ruddy face, and his white beard turned black again. Since resigning, every meeting makes him appear younger. Is this not transforming a mortal body into an immortal bone?
The Yan Shou Dan formula is now published. Various processing methods are unknown to other schools. Its benefit to humanity rivals creation. Moreover, I have seen incurable diseases cured from bedridden states, and healthy people taking it in leisure. How can one not approach the lifespan of pre-Shennong times in their later years? Recorded casually by He Lianggong, fellow provincial examinee.
A guest asked me: Can medicine kill people? I said: How can medicine kill people? It is the doctor who kills. The guest said: Is that true? I said: Listen. I advocate fitness and naturally dislike medication, often keeping secret formulas and storing good medicines to respond to the many sick and medication-dependent people in the world, which pleases me. My nephew He Dachun, eldest son of Ci De, possessed unique talent but suffered from a rare illness. Doctors said he could not be saved, and everyone agreed, setting a date for death: some said three days, some five, some seven, all gone within ten days. Whenever I faced Ci De, I could not relieve his sorrow. Only Chen Xunzhai, after one pulse diagnosis, laughed and talked comfortably, saying he awaited the order to rise and act. Later, he did not die in three days, nor five, nor seven, nor ten. Now he walks like the wind, stronger than before illness. Only then did I believe Mr. Xunzhai truly possesses the skill to see beyond walls. Mr. Xunzhai retired in Baimen, paying attention to formulas and medicines during his leisure. Having obtained the Yan Shou Dan from Grand Secretary Dong Xuanzai, he found it effective upon self-administration and thus printed the formula to show others. Although his profession was not strictly Qibo-Huangdi lineage, he deeply investigated the essence of Taisu, surpassing even them. People invited him, and none failed to return from death to life. Thinking of other doctors competing in medication skills, even generals like Qi Jian and Po Mu might not exceed them. But Mr. Xunzhai alone focuses on nurturing primordial qi. I privately share Ci De's joy and gratitude. If critical illnesses can be revived, then the Longevity Pill can undoubtedly ensure longevity. I hope people take it eagerly without missing out. This is also my compassionate heart in keeping secret formulas and storing good medicines, answering the guest's question and expressing my views. Fang Xiangxian, fellow provincial examinee, inscribed. I have additionally authored two books: *Chang Shou Pu* (Record of Longevity) and *Jiu Ming Zhen* (Needles for Saving Lives). Anyone elderly, physically weak, or ill should study them urgently.
