马属火，所以带着火气做梦会梦见马。火趋向干燥，如果干燥不止就会枯竭，所以膏油被视为无穷无尽的源泉。药物中膏油性状的没有比得上地黄的，喂给老马吃，它又能恢复如幼马般强健。白居易的诗中说：“与你喂老马，可使（马）光彩照地。”现在的人不再懂得这种方法了。我晚年学习道术，血气衰弱耗损，就像老马一样了。想要多吃生地黄，但又不能经常得到。忽然听说循州兴宁县令欧阳叔向，在自家花园里大量种植这种药，我想写信向他索取却不敢。您与叔向是老朋友，能否代为传达这个意思呢？这种药以农历二、八月采挖的为佳，如果方便，请在当时寄给我，希望能用来煎煮服用。
治疗肺痿、客忤、鬼气传尸、伏连等病证，突然发作的心痛，霍乱呕吐腹泻，时行疫病。各种疟疾伴有瘀血，月经闭止及腹内结块，疔疮肿毒，惊痫，邪气狐媚，瘴气瘟疫等各种疾病。
苏合香、白术、朱砂、沉香、诃子肉、丁香、木香、香附子、白檀香、乌犀屑、乳香、荜茇、安息香（各一两），麝香、龙脑（各半两）。
以上药材研为细末，用炼蜜制成丸药，大小如鸡头实（芡实）。每次服用一丸，用温酒嚼服，用人参汤送服也可以。此方家家户户都有，恐怕不知道它的灵验之处罢了。本出自《广济方》，称为白术丸，后人编入《外台秘要》。《千金方》记载：真宗朝时，曾赐苏合香酒给近臣，又赐苏合香丸，从此此方在世间盛行。此药大能安定气血，抵御外邪。凡是疾病从内部产生，不知其名称的，服用此药往往有效。特别是治疗气疰、气厥、气逆不和、呕吐腹泻、营卫阻塞，尤其有神奇功效。
我所亲眼见到的案例中，曾有淮南监司官谢执方，因呕血很久，气息奄奄几乎断绝，身体极度虚弱败坏已久，手足冰冷，鼻息全无，束手无策。只有研磨苏合香丸灌服他，服完半两后便苏醒过来。又有我所乘坐的船上，有一个船工的儿子患伤寒，日久死去。但心窝处尚且温暖，不忍心不给他用药，放弃已无法救治。试着给他苏合香丸，灌服四丸后便醒来，于是痊愈。我的朋友担任两浙提点刑狱时，曾患严重腹泻。看天地都在旋转，神志不清，各种药物无效。服药约两丸后，顿时感觉轻松爽快，腹泻也停止了。我亲眼目睹从将死边缘救人的情况，数不胜数。人家不可没有此药以备急难，瘟疫流行时，尤其适宜服用，辟除疫气特别灵验。仓促间求不到人参，只用白开水送服也很好，不要用酒。古方虽然说用酒送服，但酒多则效果不佳，务必记住这一点。东阳刘使君，年轻时曾患痨病，日渐消瘦。以至于骨瘦如柴，肌肉发热盗汗，虚劳症状具备，有人劝他服用此药，共服用八九两，所有痛苦都痊愈了。另一版本中有牛黄半两，古方原本没有，是后人加上的。
Horses belong to Fire; thus, when dreaming with a Fire influence, one dreams of horses. Fire tends toward dryness; if dryness persists without end, it leads to exhaustion. Therefore, fatty oils are regarded as inexhaustible. Among medicinal substances, those possessing a fatty/oily nature, none surpasses Rehmanniae Radix (Shengdihuang, 生地黄). Feeding it to old horses restores them to the vigor of foals. Bai Juyi’s poem states: "Feeding you to the old horse, it can shine upon the ground." People today no longer understand this method. In my late years, while studying the Dao, my Blood and Qi have declined and been depleted, resembling an old horse. I wish to consume large amounts of raw Rehmanniae Radix, but cannot obtain it constantly. I suddenly heard that Ouyang Shuxiang, Magistrate of Xingning County in Xunzhou, cultivates this herb extensively in his garden. I intended to write to request some but dared not. Since you are an old friend of Shuxiang, could you convey this intention for me? This herb is best harvested in the second or eighth lunar month. If convenient, please send it to me at that time, hoping to decoct and take it.
It treats Lung Wei (Lung Atrophy), Ke Wu (Guest Malevolence), Gui Qi Chuan Shi (Ghostly Energy Transferring Corpse), Fu Lian (Hidden Continuation) and other diseases; sudden onset of Heart Pain, Huo Luan (Cholera-like syndrome with vomiting and diarrhea), Shi Qi (Seasonal Epidemic Qi); various Malaria cases with Blood Stasis, Menstrual Amenorrhea, Pi Masses (abdominal lumps), Ding Swellings (carbuncles), Jing Xian (Convulsions/Epilepsy), Xie Qi Hu Mei (Evil Spirit Seduction), Zhang Li (Miasma Plague) and myriad other ailments.
Suhe Xiang (Styrax), Baizhu (Atractylodis Macrocephalae Rhizoma), Zhusha (Cinnabar), Chenxiang (Aquilariae Lignum Resinatum), Hezi Rou (Terminalia Chebulae Mesocarp), Dingxiang (Caryophylli Flos), Muxiang (Aucklandiae Radix), Xiangfuzi (Cyperi Rhizoma), Baitanxiang (Santalum Album Lignum), Wuxi Xie (Rhinocerotis Cornu - note: modern substitute often used), Ruxiang (Olibanum), Bibie (Piperis Longi Fructus), Anshixiang (Benzoin Resin) (each 1 liang), Shexiang (Moschus), Longnao (Borneolum Syntheticum) (each 0.5 liang).
Grind the above into powder, refine honey, and make pills the size of Euryale Seed (Jiantou Shi). Take one pill per dose, chewed down with warm wine; Ginseng Decoction is also acceptable. This formula is common in households, yet people may not know its miraculous efficacy. It originally appeared in *Guangji Fang*, called Baizhu Wan, and was later compiled into *Waitai Miyao*. *Qianjin Fang* records: During the Zhenzong reign, Suhe Xiang Wine was granted to close ministers, and Suhe Xiang Wan was also bestowed, after which this formula became prevalent. This medicine greatly stabilizes Qi and Blood and repels external pathogens. For any disease arising internally whose name is unknown, taking this often yields results. It is particularly efficacious in treating Qi Zhu (Qi Transmission), Qi Jue (Qi Collapse), Qi Ni Bu He (Rebellious Qi Disharmony), Vomiting and Diarrhea, Ying Wei Blockage (Nutritive and Defensive Qi Obstruction), showing especially divine merit.
I personally witnessed cases where saving lives from near-death were countless. One such case involved Xie Zhifang, an official of the Huainan Surveillance Commission, who suffered prolonged hematemesis until he was nearly dead, emaciated and weak for a long time, with cold hands and feet and absent nasal respiration, leaving us helpless. Only by grinding Suhe Xiang Wan and forcing it down did he recover after consuming half a liang. Another instance occurred on my boat: a boatman's son died of Shanghan (Cold Damage) after a long illness. His epigastrium remained warm. Unwilling to abandon him without treatment despite hopelessness, I tried giving him Suhe Xiang Wan. After four pills were administered, he woke up and recovered. A friend of mine, serving as the Judicial Intendant of Liangzhe, once suffered severe diarrhea. The world seemed to spin around him, his spirit was disordered, and all medicines failed. After taking about two pills, he instantly felt refreshed, and the diarrhea stopped. I have witnessed saving people from the brink of death too many to count. Every household should keep this medicine for emergencies. During plague times, it is especially suitable for use, offering verified protection against epidemic qi. If Ginseng cannot be obtained in haste, plain boiled water is also good; do not use wine. Although ancient formulas state to take it with wine, using too much wine reduces efficacy. Remember this well. Liu Shijun of Dongyang suffered from Zhai (Consumption/Tuberculosis) in his youth, becoming progressively emaciated until he was skeletal, with muscle heat, night sweats, and full symptoms of Lao (Chronic Deficiency Exhaustion). Someone advised him to take this medicine. After taking eight or nine liang in total, all his suffering ceased. Another version contains Banxia (Pinelliae Rhizoma) 0.5 liang; this was not in the ancient formula but added by later practitioners.
