阿胶，产于东平郡，是用牛皮熬煮制成的，因产自东阿县而得名。如今郓州都能制作，但用阿县城北的井水熬煮的才算是真品。制作工艺是：用阿井水煎煮乌驴皮，按照通常熬胶的方法进行。那口井由官府管制，真正的阿胶极难获得，市场上售卖的很多，恐怕不是真品。查阅方书记载：阿胶之所以胜过其他胶，大体上是因为驴皮配合阿井水熬制效果才好。《广济方》治疗缓风（中风的一种，表现为肢体弛缓无力）及各类风病导致手脚不能随意活动、腰脚无力的情况，将驴皮胶炙烤至微微起泡，先煮一升葱豉粥，另外盛放；再用一升水，煮香豉二合，滤去药渣，加入胶，再煮沸六七次，待胶融化如糖浆状时，一次性服下。服药后注意保暖，并随意食用之前煮好的葱豉粥；如果冷吃，会导致呕吐逆气。连续服用三到四剂即可停止。禁忌事项同一般服药规定。此外，阿胶止泻的功效，配合蜂蜡和黄连尤为佳妙。《续传信方》记载了张仲景的调气方：治疗赤白痢疾，无论病程长短，小腹疼痛难以忍受，排便急迫且次数无常，肛门坠胀疼痛闷痛，每次发作时面色发青，手足变色者。取黄连一两（去毛），阿胶约手掌大小一块，蜂蜡如弹子大小，这三味药用水一大升，先煎阿胶使其溶解，其次放入蜂蜡，再煎至溶解，然后加入黄连末，搅拌混合均匀，分为三次服用，必须热服，冷则难以下咽，疗效神妙。这些阿胶的功效，说的都是现在的阿胶。所以陈藏器说：各种胶都能治疗风病、止泻、补虚，而驴皮胶主治风病最为显著。另外，现在医生常用黄明胶，多是牛皮制成。《神农本草经》中阿胶也使用牛皮，说明这两种皮也可以通用。然而现在的牛皮胶制作不够精细，仅作为胶粘物尚可，不堪药用。应当用鹿角熬制的胶，而鹿角胶，《神农本草经》称之为白胶，说产自云中郡。如今各地都掌握了制作方法，可以制作。但其功效和劳力成本是牛皮胶的两倍，所以很少有真品，如果不是自己制造，恐怕多为伪品。
Ejiao (Donkey-Hide Gelatin), produced in Dongping Commandery, is made by boiling cowhide, and is named after its origin in E' County. Currently, Yunzhou can also produce it, but the authentic product is made using well water from north of E' County Town. The preparation involves decocting black donkey hide with E' well water, following standard gelatin-making methods. The well is under official control, making genuine Ejiao extremely rare; most sold in the capital are likely counterfeit. Consulting medical texts: the superiority of Ejiao over other gelatins largely stems from the combination of donkey hide and E' well water. *Guangji Fang* treats Huanhuan Feng (a type of stroke characterized by flaccid paralysis) and various wind disorders causing inability to move limbs and weakness in the waist and legs. The donkey-hide gelatin is roasted until slightly blistered. First, decoct one sheng of scallion and fermented soybean porridge and set aside separately. Then, use one sheng of water to decoct two he of fragrant fermented soybeans, remove the dregs, add the gelatin, and boil for six or seven times until the gelatin melts like syrup. Take this in one dose. Keep warm and consume the previously prepared scallion and fermented soybean porridge as desired; cold consumption may induce vomiting and counterflow qi. Discontinue after three or four doses. Observe dietary restrictions as per medicinal guidelines. Furthermore, the antidiarrheal effect of Ejiao is particularly effective when combined with beeswax and Coptidis Rhizoma (*Huanglian*). *Xuan Chuan Xin Fang* records Zhang Zhongjing's Qi-Regulating Formula for treating red and white dysentery, regardless of duration, characterized by unbearable lower abdominal pain, irregular bowel movements, tenesmus and painful oppression, cyanosis of the face upon onset, and discoloration of hands and feet. Take one liang of Huanglian (Coptidis Rhizoma, hair removed), a piece of Ejiao (Donkey-Hide Gelatin) about the size of a hand, and a piece of beeswax the size of a bullet. Decoct these three ingredients in one da sheng of water. First, decoct the Ejiao until dissolved, then add the beeswax and decoct until dissolved. Finally, add powdered Huanglian, stir to mix evenly, and divide into three doses. Must be taken hot; cold administration is difficult and less effective. This formula is miraculous. These functions of Ejiao refer to the contemporary Ejiao. Therefore, Chen Cangqi stated: All gelatins can treat wind disorders, stop diarrhea, and tonify deficiency, but Donkey-Hide Gelatin is most effective for treating wind. Additionally, modern physicians often use Huangming Jiao (Yellow-Bright Gelatin), which is mostly made from cowhide. *Shennong Bencao Jing* also mentions using cowhide for Ejiao, indicating that both hides are interchangeable. However, contemporary cowhide gelatin is not refined enough; while suitable for adhesive purposes, it is unsuitable for medicinal use. One should use gelatin made from deer antlers. Deer-Antler Gelatin, referred to as Baijiao (White Gelatin) in *Shennong Bencao Jing*, was said to originate from Yunzhong Commandery. Currently, the method is available everywhere, allowing for production. However, its efficacy and labor cost are double that of cowhide gelatin, so genuine products are scarce. Unless self-manufactured, they are likely counterfeit.
