昔舍下演戏，邻人陈姓子年十三，侧楼观看，与同伴揪跌，误从楼遮阳堕下石板，仅闻一声
，急视之，则两目反张出血，鼻口耳皆振出血。其父抱归，尚有微气。有人云得熊胆酒服可

阿胶，味道甘、辛，气性平、微温，具有沉降作用，属阳，无毒。进入太阴肺经，以及肝、肾两脏。能止血、止咳，止崩漏（非经期阴道大量出血）和带下病，益气扶正以改善虚弱状态，治疗劳伤，通利小便闭塞，防止胎漏（妊娠期阴道少量出血），平息气喘急促，止住腹泻痢疾，安胎并滋养肝脏，坚固骨骼并滋补肾精，是补益肺脏的奇妙药剂，也是滋生阴液的灵药。多用确实能奏效，少用也能取得疗效。只是寻找真品为佳。
有人怀疑阿胶熬制膏方，必须取阿井的水和黑驴皮来煎煮，然而哪里能全部获取黑驴皮呢？当地若取杂色驴皮来煎膏，也可以使用吗？回答说：阿胶原本只取阿井的水，并非一定要取黑驴皮。阿井位于东方，取其“天一生水”的道理，且其水性急而下趋，清澈而沉重，这是济水注入的地方，取其去除浊邪以祛除逆乱之痰的作用。使用驴皮，是因为驴性最纯正，而取皮则是取其外现于皮肤的特性，原本不必非要黑色才能入肾。水进入肾脏，而皮走于肺部，肺主皮毛，所以使用皮。前人推崇黑驴皮，认为黑色属水，用以制约热邪从而防止生风的道理，反而是画蛇添足。
有人问：阿胶补益肺脏、滋生阴液，如何能得到真品来使用呢？回答说：出自东阿的阿胶就是真品，不必去追问真假。东阿的水，都是济水所注入的。（批注：这也对，但出自阿井的更好。）
有人问：近人制作阿胶时，多加其他药材一同煎煮，想必更有益处吧？回答说：阿胶的妙处，全在于济水。如果加入其他药味混杂其中，反而失去了它的本义。本想通过加药味来获取益处，谁知反而因为药味而丧失了利益。世人强不知以为知，大半属于这类情况。
熊胆，味道极苦。治疗男女因时行疫气热气蒸腾，变为黄疸病；治疗小儿风痰壅塞，引发惊痫（癫痫类疾病）。驱除五种疳积并杀虫，敷治恶疮以散毒。痔疮瘘管涂抹它，立刻建立奇功。此物极寒，能退大热，可以使用一次，但不宜再次使用。保存它以治疗火热兼有湿病的病症。
熊胆必须取人熊的才最好，人熊的胆长八寸，其余熊的胆不过长五、六寸罢了。
从前我家附近演戏，邻居姓陈的儿子十三岁，在侧楼观看，与同伴打闹摔倒，误从楼上的遮阳棚坠落到石板上，只听到一声响，急忙看去，则两眼上翻出血，鼻、口、耳都震动出血。他的父亲抱他回家，还有微弱气息。有人说得到熊胆酒服用可以治疗。我取出家中收藏的熊胆五分，研碎，调和大碗陈年黄酒灌服下去，过了一会儿就苏醒过来。第二天，跳跃如常。至今不明白其中的原理。然而亲身尝试并亲眼目睹，因此记录下来以等待懂行的人解读。（金孝芑识）
Donkey-hide gelatin (Ejiao, Colla Corii Asini), with a sweet and pungent taste, neutral and slightly warm in nature, possessing descending properties, belonging to Yang, and non-toxic. It enters the Taiyin Lung Meridian (Taiyin Lung Channel) as well as the Liver and Kidney organs. It stops bleeding and coughing, controls metrorrhagia (abnormal uterine bleeding) and leukorrhea (vaginal discharge), tonifies Qi and supports decline, treats labor injuries, promotes urination in cases of urinary retention, prevents fetal leakage (threatened abortion with spotting), calms asthma and shortness of breath, stops diarrhea and dysentery, calms the fetus and nourishes the Liver, strengthens bones and nourishes the Kidneys. It is a miraculous agent for benefiting the Lungs and a spiritual medicine for generating Yin. While heavy use can certainly achieve results, light use can also be effective. However, seeking authentic products is preferable.
Some doubt that preparing donkey-hide gelatin paste requires water from the A Well and skin from black donkeys. Yet, how can one always obtain black donkey skins? If local impure donkey skins are used to prepare the paste, is it usable? The answer is: Donkey-hide gelatin originally relies on the water from the A Well, not necessarily requiring black donkey skins. The A Well is located in the East, invoking the principle of "Heaven One generates Water." Its nature is urgent and flows downward, clear and heavy; it is where the Ji River pours in, serving to remove turbidity and dispel rebellious phlegm. Regarding the use of donkey skin, the donkey's nature is most pure, and the skin is taken for its manifestation on the exterior (skin surface); it does not strictly need to be black to enter the Kidneys. Water enters the Kidneys, while the skin travels to the Lungs. Since the Lungs govern the skin and hair, the skin is used. Those who previously advocated for black donkey skins argued that black belongs to Water and can control heat to prevent wind generation; this reasoning is superfluous.
Someone asks: Since donkey-hide gelatin benefits the Lungs and generates Yin, how can one obtain authentic products for use? The answer is: Gelatin originating from Dong'e is authentic, and there is no need to question its authenticity. The water of Dong'e is all injected by the Ji River. (Commentary: This is also correct, but that from the A Well is even better.)
Someone asks: Recent preparations of donkey-hide gelatin often add other medicinal ingredients during decoction, presumably making it more beneficial? The answer is: The wonder of donkey-hide gelatin lies entirely in the Ji River water. If mixed with other medicinal flavors, its original meaning is lost. One intends to gain benefits by adding herbs, yet ironically loses benefits due to them. Many people pretend to know what they do not know, which falls into this category.
Bear bile (Xiong Dan, Bile Ursi), with an extremely bitter taste. It treats men and women suffering from epidemic qi causing steaming heat, transforming into jaundice (Huangdan). It treats pediatric wind-phlegm obstruction causing convulsions and epilepsy (Jingxian). It expels five types of childhood malnutrition (Gan syndrome) and kills parasites. Applied externally to malignant sores, it disperses toxins. For hemorrhoids and fistulas, applying it yields miraculous results instantly. This substance is extremely cold and can reduce high fever. It may be used once, but should not be used repeatedly. It is stored to treat conditions involving both fire-heat and dampness.
Bear bile must be sourced from the "human bear" (Ren Xiong, likely referring to a specific type or quality of bear) to be best. The gallbladder of the human bear is eight cun long, whereas others are only five or six cun long.
Previously, when plays were performed near my residence, a thirteen-year-old son of a neighbor surnamed Chen was watching from a side balcony. He wrestled with companions, fell accidentally from the balcony awning onto stone slabs, heard only one sound, and upon rushing to look, his eyes were rolled back with blood flowing, and his nose, mouth, and ears were vibrating with blood. His father carried him home; he still had faint breath. Someone said that consuming bear bile wine could treat this. I took five fen of my family's stored bear bile, ground it into powder, mixed it with a large bowl of aged yellow wine, and forced it down his throat. After a short while, he revived. The next day, he jumped around as usual. To this day, I do not understand the rationale. However, having personally tested and witnessed it, I recorded it here awaiting those who understand.
