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。

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).
