雷公云∶凡使，要绿色、九肋、多裙、重七两者为上。
治气、破块、消症、定心药中用之，每个鳖甲，以六一泥固济瓶子底了，干，于大火，
以物 于中，与头醋下火煎之，尽三升醋为度，乃去裙并肋骨了，方炙干，然入药中用。
又治劳、去热药中用。依前泥，用童子小便煮，昼夜尽，小便一斗二升为度，后去裙，
留骨，于石上捶，石臼中捣，成粉了，以鸡 皮裹之，取东流水三、两斗，盆盛，阁于盆上
一宿，至明，任用。力有万倍也。
雷公云∶凡使，要白花全者。
凡收得后，于屋下东角悬干，去甲土后，用浆水煮一日，至夜，焙干，碾细用之。
雷公云∶凡使，桑树、柏树中者妙。
凡收得后，阴干，干后与糯米同炒，待米焦黑为度。然后去米取之，去口畔并身上肉毛
并黑尘了，作三、四截，碾成粉用之。
雷公云∶凡使，勿用沙鱼骨，缘真相似，只是上文横，不入药中用。凡使，要上文顺浑
。用血卤作水浸，并煮一伏时了，漉出，于屋下掘一地坑，可盛得前件乌贼鱼骨多少，先烧
坑子，去炭火了，盛药，一宿至明，取出用之，其效倍多。
雷公云∶凡使，先须以糯米泔浸一日，待蚕桑涎出，如蜗牛涎，浮于水面上，然后漉出
，微火焙干，以布净拭蚕上黄肉毛，并黑口甲了，单捣，筛如粉用也。
雷公说：凡是使用鳖甲，要选择绿色、有九个肋骨、裙边多、重量达到七两的作为上品。
在治疗气滞、破除积块、消除症瘕、安定心神等药物中使用时，每个鳖甲要用六一泥将瓶子底部密封好，待干后，在猛火下，用物体垫在中间，加入头醋一起煎煮，以消耗完三升醋为限度，然后去掉裙边和肋骨，再炙烤至干燥，这样才放入药中使用。
另外，在治疗虚劳、清除热邪的药物中使用时，也按照前面的方法用泥密封，用童便（小男孩的小便）来煮，昼夜不停，以消耗一斗二升童便为限度，之后去掉裙边，保留骨骼，在石头上捶打，在石臼中捣碎，成为粉末后，用鸡皮包裹起来，取东流水三到两斗，盛在盆里，将包裹好的鳖甲粉搁置在盆上一整夜，直到第二天早上，就可以随意使用了，其药效会有万倍之强。
雷公说：凡是使用白僵蚕，要选择白色花纹完整者。
凡是采收回来后，挂在屋子下面的东角晾干，去掉附着的泥土后，用浆水（发酵的米汤）煮一天，到了晚上，焙干，碾成细末使用。
雷公说：凡是使用乌贼鱼骨（海螵蛸），以生长在桑树、柏树中的为佳。
凡是采收回来后，阴干，干后与糯米一同炒制，等到米粒炒得焦黑为限度。然后去掉米粒，去除乌贼鱼骨嘴部边缘以及身上的肉毛和黑尘，切成三到四截，碾成粉末使用。
雷公说：凡是使用乌贼鱼骨，不要用沙鱼骨，因为真的乌贼鱼骨与沙鱼骨相似，只是纹理方向不同（真品纹理顺，沙鱼骨横），不能入药使用。凡是使用，要选择纹理顺直浑圆者。用血卤（咸卤水）浸泡，并煮一个时辰（两小时），捞出后，在屋子下面挖一个地坑，大小刚好能容纳前文所述的乌贼鱼骨多少，先烧坑，去掉炭火后，装入药材，放置一整夜到第二天早上，取出使用，其疗效会倍增。
雷公说：凡是使用白僵蚕，必须先以淘米水浸泡一天，等到蚕体内的涎液流出，像蜗牛的涎液一样浮在水面上，然后捞出，用微火焙干，用布擦干净蚕身上的黄色肉毛和黑口甲，单独捣碎，筛成粉末使用。
Lei Gong said: When using the carapace of a soft-shelled turtle (Biejia, 鳖甲), select those that are green, have nine ribs, possess abundant skirt-like edges, and weigh seven taels as the highest grade.
When used in formulas for regulating Qi, breaking up masses, eliminating accumulations (Zhengjia, 症瘕), and calming the mind, each piece of Biejia should be sealed at the bottom of a bottle with Liuyi mud (a mixture of six parts clay and one part other materials). After drying, place it over a strong fire with an object underneath, add first-grade vinegar, and decoct until three sheng (approximately 600ml) of vinegar is consumed. Then remove the skirt and ribs, roast until dry, and then incorporate into medicinal preparations.
Additionally, when used in formulas treating consumptive diseases (Laobing, 劳病) or clearing heat, follow the previous method using mud sealing, but decoct with urine from a healthy young boy (Tongzi Xiaoshui, 童子小便) continuously day and night until one dou two sheng (approximately 2.4 liters) of urine is consumed. Afterwards, remove the skirt, retain the bone, pound it on stone, grind it in a stone mortar into powder, wrap it in chicken skin, take three to two dou (3-20 liters) of running water from the east, place it in a basin, suspend the wrapped powder over the basin overnight. By morning, it is ready for use; its efficacy will be ten thousand times greater.
Lei Gong said: When using the dried larva of a silkworm infected by a fungus (Baijiangcan, 白僵蚕), select those with complete white patterns.
After harvesting, hang them under the eaves in the eastern corner to dry naturally. After removing soil impurities, decoct them in fermented rice water (Jiangshui, 浆水) for one day. At night, bake them dry, grind them into fine powder, and use.
Lei Gong said: When using cuttlefish bone (Haipiaoxiao, 海螵蛸), those sourced from mulberry or cypress trees are superior.
After harvesting, dry them in the shade. Once dry, stir-fry them together with glutinous rice until the rice turns charred black. Then remove the rice, clean the cuttlefish bone by removing the beak area, body hairs, and black dust, cut into three or four pieces, grind into powder, and use.
Lei Gong said: When using Haipiaoxiao, do not use shark cartilage/bone because it resembles the true material but has transverse grain patterns and is unsuitable for medicinal use. Select those with smooth, rounded longitudinal grain patterns. Soak and decoct them in saline brine (Xuelu, 血卤) for one shichen (two hours). Strain out, dig a pit under the eaves large enough to hold the specified amount of cuttlefish bone. First burn the pit, remove the charcoal embers, place the medicine inside, leave overnight until morning, then retrieve and use; its efficacy will be doubled.
Lei Gong said: When using Baijiangcan, first soak it in rice washing water for one day. Wait until the serous fluid from the silkworm emerges, resembling snail slime floating on the surface of the water. Then strain it out, bake it dry over a mild fire, wipe off the yellow fleshy hairs and black mouthparts/claws with a clean cloth, crush it alone, sieve it into powder, and use.
