阿胶，后世有补血之说。然今读诸家本草，其所主治，皆是在于治瘀血也。凡久年咳嗽、
赤白痢下下血、吐血、咯血、衄血、呕血、老人大便秘结、或小便淋沥、及见血、妇人经水
诸变、妊娠之病，无不属瘀血者。古方既然，后世诸方，皆然宜矣。今医见之，谓之补血药。
虽然，以余观之，谓之化血而可也。何以言之？则阿胶配之猪苓、泽泻、滑石，则泻瘀血于
小便；配之大黄、甘遂则下瘀血于大便；配之黄芩、黄连，则除瘀血心中烦者；配之甘草、
黄柏、秦皮、白头翁，则治瘀血热利下重者；配之当归、芎 、地黄、芍药、艾叶，则止瘀
血腹中 痛者；配之术、附子、黄土，则治瘀血恶寒、小便不利者。由此观之，则岂谓之补
血可乎？后世皆见其枝叶，而不知其根本。医之所以误治者不亦宜乎？
阿胶以阿县所制者为名。今华舶来之物数品，入药当以黄透如琥珀色为上品。或光黑如
漆，不作皮臭者为良。若真物难得，则此邦皮胶黄透，夏月不湿软者可权用。

阿胶，后世有补血的说法。然而如今阅读各家本草著作，发现其所主治的病症，都在于治疗瘀血。凡是多年的咳嗽、赤白痢疾伴下血、吐血、咯血、鼻出血、呕血、老年人严重便秘、或小便淋漓不畅、以及出现各种出血症状、妇女月经的各种异常变化、妊娠期间的疾病，没有不属于瘀血的。古代方剂既然这样记载，后世的各方剂也应当如此理解。现在的医生见到这些用法，称之为补血药。虽然如此，但在我看来，称其为化血（化解瘀血）的药是可以的。为什么这样说呢？因为阿胶配合猪苓、泽泻、滑石，就能通过小便排出瘀血；配合大黄、甘遂，就能通过大便排出瘀血；配合黄芩、黄连，就能清除心中因瘀血引起的烦闷；配合甘草、黄柏、秦皮、白头翁，就能治疗因瘀血导致的热利且伴有里急后重的症状；配合当归、川芎、地黄、芍药、艾叶，就能停止因瘀血引起的腹部疼痛；配合白术、附子、灶心黄土，就能治疗因瘀血导致的恶寒、小便不利的症状。由此看来，怎么能称之为补血药呢？后世的人只看到了它的枝叶末节，而不知道它的根本所在。医生因此误治，不也是应该的吗？
阿胶以阿县所制作的称为正宗。现在从海外船只运来的物品有好几种，入药时应当以黄色透明如琥珀色者为上品。或者光泽黑亮如漆，没有皮革臭味者为良。如果真品难以获得，那么本国生产的皮胶中，黄色透明、夏季不发软潮湿的也可以权且使用。

Jiao-E (Donkey-Hide Gelatin), in later generations, has been said to have the function of nourishing blood. However, upon reading various materia medica works today, it is found that its indicated conditions all lie in treating blood stasis. Any chronic cough for many years, dysentery with red and white discharge accompanied by bleeding, hematemesis, hemoptysis, epistaxis, hematemesis, severe constipation in the elderly, or dribbling urination, as well as various bleeding manifestations, various abnormalities in women's menstrual flow, and diseases during pregnancy, all belong to blood stasis. Since ancient formulas record this, subsequent formulas should also be understood in this manner. Modern physicians, seeing these applications, call it a blood-nourishing drug. Although so, in my view, it can be called a drug that transforms blood (resolves blood stasis). Why do I say so? Because when Jiao-E is combined with Zhu-Ling (Polyporus), Ze-Xie (Alisma), and Hua-Shi (Talcum), it expels blood stasis through urine; when combined with Da-Huang (Rhubarb) and Gan-Sui (Kansui), it expels blood stasis through stool; when combined with Huang-Qin (Scutellaria) and Huang-Lian (Coptis), it clears the vexation in the heart caused by blood stasis; when combined with Gan-Cao (Licorice), Huang-Bai (Phellodendron), Qin-Pi (Ash Bark), and Bai-Tou-Weng (Pulsatilla), it treats heat-dysentery with tenesmus caused by blood stasis; when combined with Dang-Gui (Angelica Sinensis), Xiong-Ku (Ligusticum), Di-Huang (Rehmannia), Shao-Yao (Peony), and Ai-Ye (Mugwort Leaf), it stops abdominal pain caused by blood stasis; when combined with Bai-Zhu (Atractylodes), Fu-Zi (Aconite), and Huang-Tu (Fired Earth), it treats chills and difficulty in urination caused by blood stasis. From this perspective, how can it be called a blood-nourishing drug? Later generations only see its branches and leaves, but do not know its root. Is it not appropriate that physicians therefore treat incorrectly?
Jiao-E takes its name from those produced in A County. Among the various items imported by foreign ships today, for medicinal use, those that are yellow and transparent like amber are considered the highest grade. Those that are glossy and black like lacquer, without a leather odor, are good. If the genuine product is hard to obtain, then domestically produced hide gelatin that is yellow and transparent and does not become soft and damp in summer can be used as a substitute.

Jing refers to the non-glutinous variety of rice, also known as Jing. Luo Yuan stated: Rice, also named Jing, comes in glutinous and non-glutinous varieties. Nowadays, people call the glutinous one Nuo (glutinous rice) and the non-glutinous one Jing (indica rice).
