熟干地黄 元参 当归 羌活（各等分）
上捣为末，蜜和丸，梧桐子大，空心酒服，丸数随宜。《列仙传》有山图者，入山采药
折足，仙人教服此四物而愈。因久服，遂度世。顷余以问名医康师孟。师孟大异之云，医家
用此多矣。然未有专用此四物如此方者，师孟遂名之曰四神丹。洛下公卿士庶争饵之，百病
皆愈。药性中和，可常服。大略补虚益血，治风气，亦可名草还丹。己卯十一月，东坡居士

世传四味五两天麻煎方。盖古方，本以四时加减，但传药料耳。春肝旺多风，故倍天麻；

熟地黄、玄参、当归、羌活（各取等量）
将上述药材捣碎成粉末，用蜂蜜调和制成丸药，大小如梧桐子，空腹时以酒送服，丸药的服用数量根据情况自行调整。《列仙传》中记载有一位叫山图的人，进山采药时摔断了腿，仙人教导他服用这四种药物后痊愈。因为长期服用，最终得道成仙。不久前我曾向名医康师孟询问此事。康师孟对此感到非常惊奇，说：“医生们使用这些药物的很多。”然而，没有人专门像这个方子一样只用这四味药。康师孟于是将其命名为“四神丹”。洛阳地区的公卿士大夫和平民百姓争相服用，各种疾病都治愈了。该药药性平和，可以经常服用。大致功效是补虚养血，治疗风气病，也可以称为“草还丹”。己卯年十一月，东坡居士在儋耳书写。
世间流传的“四味五两天麻煎方”。这是古方，原本是根据四季变化进行加减，但只流传了药物材料。春季肝气旺盛且多风，所以加倍天麻；夏季阴气潜伏，所以加倍乌头；秋季容易腹泻，所以加倍地榆；冬季阳气潜伏，所以加倍玄参。使用时应当去皮生用，经过炮制处理后，乌头的毒性就消除了。这种药常服不仅能去除疾病，还能保养真气、延年益寿，可以与张仲景的八味丸相媲美。
治疗偏瘫、中风瘫痪、脚气病等疾病。
羌活（一两）、麻黄（去节，水煮片刻后撇去浮沫，二两）、防风（三分）、木香、槟榔、附子（炮制后去皮）、白术、川乌头（炮制后去皮）、草豆蔻（带皮使用）、陈皮、牛膝（酒浸泡一夜）、杏仁（生用，去皮尖）、当归（酒浸泡一夜）、人参、茯苓、甘草（炙烤）、川芎、官桂（不得见火，各半两）
以上十八味药，切碎如麻豆大小，每次服用一两，加水一碗，生姜七片。煎煮至一盏量，滤去药渣，取七分药液温服。如果大肠不通畅，加入大黄末，每次服用一钱。根据患者年龄和体质增减剂量。如果是长期不通畅，增加至三到五钱也无妨。如果心腹胀满，加入葶苈子和滑石末，每次各服用一钱，用滑石汤送下。如果上焦壅滞、痰嗽气急，加入半夏、升麻、天门冬、知母末，各二钱一同煎煮。剩下的药渣再加水一碗半，煎煮至一盏量，服用此药。福唐的陈氏靠卖此药维持生计，郡中百姓认为它非常灵验。人们一直没有得到这个方子，有一天被他的亲戚偷来给了我。我在任职的地方，就配制此药施舍给人。按照方法煮服，以……
Prepared Rehmanniae Radix (Shudihuang), Scrophulariae Radix (Yuannan), Angelicae Sinensis Radix (Danggui), and Notopterygii Rhizoma et Radix (Qianghuo) (equal parts).
Crush the above ingredients into powder, mix with honey to form pills, sized like Sophora japonica seeds. Take on an empty stomach with wine; the number of pills should be adjusted as appropriate. *Lie Xian Zhuan* (Biographies of Immortals) records a man named Shan Tu who broke his leg while gathering herbs in the mountains. An immortal taught him to take these four substances, after which he recovered. Due to long-term consumption, he eventually attained immortality. Recently, I asked the famous physician Kang Shimeng about this. Kang was greatly surprised and said, "Many physicians use these drugs." However, no one has exclusively used these four ingredients in such a specific manner as this prescription. Kang thus named it "Si Shen Dan" (Four Divine Pills). The nobles, officials, scholars, and commoners in Luoyang competed to take it, and various diseases were cured. The medicinal nature is mild and harmonious, suitable for regular consumption. Its general effects are tonifying deficiency and benefiting blood, treating wind-pathogens, and it can also be called "Cao Huan Dan" (Herb Returning Pill). Written by Dongpo Jushi in Dan'er in November of the Jimo year.
The widely circulated "Si Wei Wu Li Tianma Jian Fang" (Four-Ingredient Five-Day Gastrodia Decoction). This is an ancient prescription, originally modified according to the four seasons, but only the herbal materials have been transmitted. In spring, when Liver Qi is vigorous and wind is prevalent, double the amount of Gastrodiae Rhizoma (Tianma); in summer, when Yin is latent, double the amount of Aconiti Lateralis Radix Praeparata (Wutou); in autumn, when diarrhea is common, double the amount of Sanguisorbae Radix (Diyu); in winter, when Yang is latent, double the amount of Scrophulariae Radix (Yuannan). When used, the bark should be removed and taken raw; through proper processing, the toxicity of Wutou is eliminated. Regular consumption of this not only cures diseases but also preserves true Qi and prolongs life, rivaling Zhang Zhongjing's Ba Wei Wan (Eight-Ingredient Pill).
Treating hemiplegia, stroke-induced paralysis, gouty arthritis, and other ailments.
Notopterygii Rhizoma et Radix (Qianghuo) (1 liang), Ephedrae Herba (Mahuang) (devoid of joints, boiled briefly to remove foam, 2 liang), Saposhnikoviae Radix (Fangfeng) (3 fen), Costi Rhizoma (Muxiang), Arecae Semen (Binglang), Aconiti Radix Praeparata (Fuzi) (processed and devoid of skin), Atractylodis Macrocephalae Rhizoma (Baizhu), Aconiti Radix (Chuanwutou) (processed and devoid of skin), Cardamomi Fructus (Caoudoukou) (used with skin), Citri Reticulatae Pericarpium (Chenpi), Achyranthis Bidentatae Radix (Niuxi) (soaked in wine overnight), Armeniacae Semen Amarum (Xingren) (raw, devoid of skin and tip), Angelicae Sinensis Radix (Danggui) (soaked in wine overnight), Ginseng Radix (Renshen), Poria (Fuling), Glycyrrhizae Radix et Rhizoma (Gancao) (roasted), Chuanxiong Rhizoma (Chuanxiong), Cinnamomi Ramulus (Guangui) (must not touch fire, each half liang).
The above eighteen ingredients are chopped like hemp seeds. For each dose, take 1 liang, add one bowl of water and seven slices of ginger. Decoct until reduced to one bowl, strain, and take 70% of the liquid warm. If large bowel obstruction occurs, add Powder of Rhei Radix et Rhizoma (Dahuang), taking 1 qian per dose. Adjust based on age and constitution. If chronic, increasing to 3–5 qian is harmless. If there is abdominal distension and fullness, add Semen Lepidii et Descurainiae (Tingli) and Talcum (Huashi) powder, taking 1 qian of each per dose, delivered with Huashi decoction. If there is upper jiao stagnation, phlegm-cough, and shortness of breath, add Pinelliae Rhizoma (Banxia), Cimicifugae Rhizoma (Shengma), Asparagi Radix (Tianmendong), and Anemarrhenae Rhizoma (Zhimu) powder, 2 qian of each, decocted together. Combine the dregs from two doses, add one and a half bowls of water, decoct to one bowl, and consume this medicine. Mr. Chen from Futang sold it to support himself, and the locals considered it miraculous. No one had obtained the formula until one day his relative stole it and gave it to me. While serving as an official, I prepared it to distribute to people. Boil and take as directed...
