雷公云∶凡使，勿用三、四年者，无力。用二十年已来者，心空，其树只有半边向西生
者是。
凡修事，斧剥下，去上粗皮，细锉，蒸，从巳至未，出，焙干用。
雷公云∶凡使，只用内无皱壳者，用，力大。汉椒使壳，胡椒使子。
每修拣了，于石槽中碾碎成粉用。
雷公云∶凡使，去粗皮一重，取橡实蒸，从巳至未，出，锉作五片用之。
雷公云∶凡采得后，粗捣，用酥炒令酥尽为度，然入用。
每一两，用酥二分为度。
雷公云∶凡使，其麋角，顶根上有黄色毛若金线，兼旁生小尖也。色苍白者上。注∶《
干宁记》云其鹿与游龙相戏，乃生此异尔。
雷公云∶凡使，先须细认，其伪者多。其海中有兽，号曰水鸟龙，海人采得，煞之取肾
，将入诸处。在药中修合，恐有误，其物自殊。有一对，其有两重薄皮，裹丸气肉核，皮上
自有肉黄毛，三茎共一穴，年年 湿，常如新，兼将于睡着犬，蹑足置于犬头，其犬蓦惊如
狂，即是真也。
若用，须酒浸一日后，以纸裹，微微火上炙令香，细锉，单捣用也。
雷公云∶凡使，有多般，勿误用。有黑虎、有 黄、有黄KT 、有蝼蝈、有蟾，其形
各别。其虾蟆，皮上腹下有斑点，脚短，即不鸣叫；黑虎，身小黑，觜脚小斑； 黄，斑色，
前脚大，后腿小，有尾子一条。黄KT ，遍身黄色，腹下有脐带，长五、七分已来，所住
立处，
凡使虾蟆，先去皮并肠及爪了，阴干，然后涂酥炙令干。每修事一斤，用牛酥一分，炙
尽为度。
雷公说：凡是使用榉树皮，不要选用生长三、四年的，因为药力不足。应选用生长二十年以上的，如果树心已空，且只有半边向西生长的才是合格的。
凡是炮制时，用斧头剥下树皮，去掉上层的粗皮，切成细丝，进行蒸制，从巳时（上午9-11点）到未时（下午1-3点），取出后焙干备用。
雷公说：凡是使用汉椒（花椒），只选用内部没有皱缩外壳的，这样药效大。汉椒用其壳，胡椒用其果实。
每次挑选整理好后，在石槽中碾碎成粉末使用。
雷公说：凡是使用橡实（橡树的果实），去掉一重粗皮，取橡实进行蒸制，从巳时到未时，取出后，切成五片使用。
雷公说：凡是采集后，先粗略捣碎，用酥油炒至酥油被完全吸收为止，然后入药使用。
每一两药材，用酥油二分为限度。
雷公说：凡是使用麋角，其角根顶部有黄色毛发如同金线，并且旁边生出小尖刺。颜色苍白的是上品。注释：《干宁记》记载，这是因为鹿与游龙嬉戏，才产生这种奇异现象。
雷公说：凡是使用水鸟龙（一种海中生物，疑似海狗或类似海洋哺乳动物的肾脏），必须先仔细辨认，因为伪品很多。海中有种兽类，名叫水鸟龙，海边人捕获它，杀死后取其肾脏，将其混入各地药材中。在药物炮制配合中，恐怕会有误认，因为该物本身性质特殊。有一对特征：有两层薄皮包裹着丸状的气肉核，皮上自然长有肉黄色的毛，三个毛孔共用一个穴道，年年潮湿，常如新的一样。另外，将睡着的狗脚放在它的头上，狗突然受惊发狂，这就是真品。
如果使用，必须用酒浸泡一天后，用纸包裹，在微火上烤至发出香味，切成细丝，单独捣碎使用。
雷公说：凡是使用虾蟆（蟾蜍），有多种种类，不要误用。有黑虎、有黄、有黄KT（此处原文可能有缺字或异体字，指某种特定蟾蜍）、有蝼蝈（蝼蛄？此处语境似指蟾蜍变种）、有蟾，它们的形态各不相同。其中虾蟆，皮上腹部有斑点，脚短，不鸣叫；黑虎，身体小黑，嘴和脚有小斑点；黄，斑色，前脚大，后腿小，有一条尾巴。黄KT，全身黄色，腹部有脐带样结构，长约五、七分。所居住的地方……
凡是使用虾蟆，先去皮并去除肠子和爪子，阴干，然后涂酥油炙烤至干燥。每次炮制一斤，用牛酥一分，炙烤至酥油尽为限度。
Lei Gong said: When using the bark of Zelkova schneideriana (Zhu Pi), do not use those grown for three or four years, as they lack potency. Use those grown for twenty years or more; if the heart is hollow and only half grows towards the west, that is the correct one.
For processing, peel off with an axe, remove the outer rough bark, cut into fine shreds, steam from Si hour (9-11 AM) to Wei hour (1-3 PM), take out, and bake dry for use.
Lei Gong said: When using Huajiao (Sichuan Pepper, Zanthoxylum bungeanum), only use those without wrinkled shells inside, as they have greater efficacy. For Huajiao, use the shell; for Hujiao (Black Pepper, Piper nigrum), use the fruit.
After each selection and sorting, grind into powder in a stone trough for use.
Lei Gong said: When using Xiangshi (Acorn, Quercus variabilis nut), remove one layer of rough skin, steam the acorns from Si hour to Wei hour, take out, cut into five slices for use.
Lei Gong said: After harvesting, crush coarsely first, stir-fry with su (animal fat/butter) until the su is completely absorbed, then incorporate into medicine.
For every liang (approx. 37g) of herb, use two fen (approx. 0.37g) of su as the limit.
Lei Gong said: When using Mi Jiao (Elk Horn, Cervus elaphus antler), there should be yellow hair like golden threads at the top root of the horn tip, along with small sharp spikes growing on the sides. Those with pale white color are superior. Note: "Ganning Ji" records that this anomaly arises from deer playing with swimming dragons.
Lei Gong said: When using Shui Niao Long (Sea Bird Dragon, likely referring to Sea Dog/King Eider kidney or similar marine mammal organ), one must first carefully identify it, as there are many fakes. There is a beast in the sea called Shui Niao Long; fishermen catch it, kill it, and take its kidneys to sell in various places. In medicinal preparation, confusion may occur because the substance itself is distinct. It has a pair of features: two layers of thin skin wrapping a丸-shaped qi-meat core, with natural yellowish meat-hair on the skin; three stems share one pore, remaining moist year-round and looking new. Additionally, place it under the head of a sleeping dog; if the dog suddenly startles and goes mad, it is genuine.
If used, soak in wine for one day, wrap in paper, roast gently over fire until fragrant, cut into fine shreds, and pound alone for use.
Lei Gong said: When using Xia Ma (Toad, Bufo bufo gargarizans), there are many types; do not use them by mistake. There are Hei Hu (Black Tiger Toad), Huang (Yellow Toad), Huang KT (a specific type), Lou Gu (Mole Cricket? Context suggests toad variant), and Chan (Toad); their shapes differ. The Xia Ma has spots on its belly skin, short legs, and does not croak; Hei Hu is small and black with small spots on mouth and feet; Huang has spotted coloration, large front legs, small hind legs, and one tail. Huang KT is yellow all over, with an umbilical cord-like structure on the belly, about five to seven fen long. Wherever it resides...
When using Xia Ma, first remove the skin, intestines, and claws, dry in shade, then coat with su and roast until dry. For every jin (approx. 500g) processed, use one fen of niu su (cow butter/ghee), roasting until the su is fully absorbed.
