阿胶味甘、咸，性微温，无毒，归肺、肝、肾三经。主治风邪亢盛导致的肢体关节痿软疼痛，火气过盛导致肺气虚弱引起的喘咳痰血，补益虚劳损伤，治疗崩漏和带下病，滋养肾脏并安胎，益气并止痢。以色泽明澈如水、质地脆硬易折断者为真品。山药可作为引经药，忌与大黄同用，蛤粉炒至成珠状后使用。
按语：阿胶是用黑驴皮熬制而成，黑色属水，专入肾经，能克制火邪，这是基于“制约热邪则风气自息”的原理，所以适宜入肝经。而且火邪被制约后，肺金也不会受其侵扰，所以又适宜入肺经。东阿井的水源于济水，水性急而下趋，清澈且沉重，用它来煎煮阿胶……（原文此处中断）
熊胆味苦，性寒，无毒，归胆经。主治时行热病热势炽盛，转变为黄疸，小儿风痰壅盛引起的寒战、惊痫、疳积，杀虫解毒，可外敷治疗恶疮及痔疮。将熊胆放入水中搅拌，若像白绢一样不散开者为真品，忌与防己、地黄同用。
按语：熊胆入胆经，是取同类相从之意，其清火定惊的功效，胜过其他动物的胆汁。
雷公说：凡是采收后，需在炼制的器具中安放好，每一斤熊胆，加入生花椒十四个，炼制去渣，并将花椒一同装入瓶中，随时取用。
腽肭脐味咸，性大热，无毒，归脾经、命门二经。主治辅助肾脏增添精液，补益中气、益气，治疗鬼气尸疰（一种传染性极强的痨病），梦交，宿血瘀结，心腹疼痛。将其放在熟睡的狗旁边，若狗惊恐狂跳不止，放入水中不结冰者为真品，用酒浸泡一夜，用纸包裹在文火上烤脆，细切捣碎后使用。
按语：腽肭脐属于咸热之品，本入命门以补火，脾脏所喜好的温热之气，正是腽肭脐的热性，所以也入脾经。其助阳的功效，在众多方剂中独占鳌头，现在产于登州、莱州，即海狗肾。其形状头部像猪，尾巴像鱼，只有两只脚，价格非常昂贵。市面上假货很多，必须仔细辨别。
雷公说：凡是要使用时，必须先仔细辨认伪品。海中有一种兽叫水乌龙，海人采集其肾脏，用来冒充腽肭脐。混入各种药物中，炮制配伍恐怕会有误。这种物产本身很特殊，有一对，有两层薄皮包裹着丸状的核，皮上自有肉黄色的毛。一穴长出三根茎，收在容器中，年年湿润如新，放在狗头上，狗会惊恐狂跳，这就是真品。需要用酒浸泡一天，然后用纸包裹在微火上烤至香气四溢，细切单独捣碎使用。
A-E-Jiao (Donkey-Hide Gelatin) tastes sweet and salty, is slightly warm in nature, non-toxic, and enters the Lung, Liver, and Kidney meridians. It primarily treats wind-pathogen hyperactivity causing flaccidity and pain in limbs and joints; excessive fire leading to deficiency of Metal (Lung), manifesting as wheezing, coughing, and hemoptysis; it tonifies consumptive diseases, treats metrorrhagia and leukorrhea, nourishes the Kidney and calms the fetus, benefits Qi, and stops dysentery. The genuine product is clear as water and brittle, breaking easily. Shen Yao (Dioscoreae Rhizoma) serves as a guiding drug; it is incompatible with Da Huang (Rhei Radix et Rhizoma). It should be stir-fried with Ge Fen (Calcitum) until it forms beads for use.
Note: A-E-Jiao is made from the skin of black donkeys. Black corresponds to Water and specifically enters the Kidney meridian, where it can subdue Fire. This aligns with the principle that restraining heat prevents the generation of wind, thus making it suitable for entering the Liver meridian. Furthermore, when Fire is restrained, Metal (Lung) is not invaded, so it is also suitable for entering the Lung meridian. The well at Dong-E County originates from the Ji River; its nature is swift and downward-flowing, clear and heavy. When used for decoction... [text cuts off]
Xiong Dan (Bear Bile) tastes bitter, is cold in nature, non-toxic, and enters the Gallbladder meridian. It primarily treats epidemic febrile diseases with intense heat transforming into jaundice; pediatric conditions involving phlegm-heat obstruction, chills, convulsions, epilepsy, and infantile malnutrition; it kills parasites and disperses toxicity, and can be applied externally to treat malignant sores and hemorrhoids. The genuine product, when stirred into water, remains intact like white silk; it is incompatible with Fang Ji (Stephaniae Tetrandrae Radix) and Di Huang (Rehmanniae Radix).
Note: Xiong Dan enters the Gallbladder meridian, following the principle of similarity. Its efficacy in clearing fire and calming convulsions surpasses that of other animal bile.
Lei Gong stated: After collection, place it in a refining vessel. For every jin (approx. 500g) of Xiong Dan, add fourteen raw Sichuan peppercorns (Zanthoxyli Pericarpium), refine to remove dregs, and store together with the peppercorns in a bottle for future use.
Wa Na Qi (Otter Testis/Gonad) tastes salty, is extremely hot in nature, non-toxic, and enters the Spleen and Mingmen (Gate of Life) meridians. It primarily assists the Kidney in replenishing essence, tonifies the Middle Jiao and benefits Qi, treats "ghost qi" and corpse transmission (highly contagious tuberculosis-like diseases), nocturnal emissions with dream intercourse, blood stasis accumulation, and abdominal pain. The genuine product causes a sleeping dog to jump and run in fright when placed nearby, and does not freeze when put in water. Soak in wine for one night, wrap in paper, roast over gentle heat until crisp, then finely chop and pound for use.
Note: Wa Na Qi is a salty and hot substance, originally entering the Mingmen to tonify Fire. The warmth preferred by the Spleen is precisely the heat of Wa Na Qi, so it also enters the Spleen. Its function of assisting Yang ranks supreme among various preparations. It is currently produced in Dengzhou and Laizhou, which is the testis of the sea dog (sea lion/otter). Its head resembles a pig, its tail resembles a fish, and it has only two feet. Its price is exceptionally high. There are many fakes on the market, requiring careful discrimination.
Lei Gong stated: Before use, one must carefully identify fakes. There is an aquatic beast in the sea called Shui Wu Long (Water Black Dragon); fishermen collect its kidneys to pass them off as Wa Na Qi. Mixing this into medicinal preparations may cause errors during compounding. This substance is unique: there is a pair, consisting of two thin layers of skin wrapping a丸-shaped core, with yellowish fleshy hair on the skin. One orifice produces three stalks. Stored in a container, it remains moist and fresh year-round. Placed on a dog's head, if the dog jumps in fright as if mad, it is genuine. It must be soaked in wine for one day, then wrapped in paper and roasted over slight heat until fragrant, then finely chopped and pounded separately.
