雷公云∶凡收得后，炼过，就器中安生椒，每一斤熊脂，入生椒十四个，炼了，去脂革
并椒，入瓶中收，任用。
雷公云∶凡使，勿用杂胆。其象胆干了，上有青竹纹斑，并光腻，微微甘。
凡用，勿便和众药捣，此药先捣成粉，待众药末出，然后入药中。
此物是胡人杀得白象取胆，干，入汉中是。
雷公云∶凡使，采得鹿角了，须全戴者，并长三寸锯解之，以物盛，于急水中浸之；一
百日满出，用刀削去粗皮一重，了，以物拭水垢令净；然后用碱醋煮七日，旋旋添醋，勿令
火歇，戌时不用着火，只从子时至戌时也；日足，其角白色软如粉，即细捣作粉；却，以无
灰酒煮其胶，阴干，削了，重研，筛过用。
每修事十两，以无灰酒一镒，煎干为度也。
雷公云∶凡使，先于猪脂内浸一宿；至明出，于柳木火上炙，待泡了，细碾用。
雷公云∶是酪之浆。
凡用，以绵重滤过，于铜器中沸三、两沸了用。
雷公云∶鸡子，凡急切要用，勿便敲损，恐得二十一日满，在内成形，空打损后无用。
内有自溃者，亦不用也。
雷公云∶凡炼蜜一斤，只得十二两半或一分是数。若火少、火过，并用不得。
雷公云∶有石牡蛎、石鱼蛎、真海牡蛎。石牡蛎者，头边背大，小甲沙石，真似牡蛎，
只是圆如龟壳；海牡蛎使得，只是丈夫不得服，令人无髭；真牡蛎，火 白炮，并用 试之
，随手走起，可认真是。万年珀，号曰 ，用之妙。
凡修事，先用二十个，东流水，盐一两，煮一伏时；后，入火中烧令通赤；然后入钵中
研如粉用也。
Lei Gong said: After collection and refining, place raw Sichuan pepper (Zanthoxyli Pericarpium) in the vessel. For every jin (approx. 500g) of bear fat (Xiong Zhi), add fourteen raw Sichuan peppers. After refining, remove the solidified fat skin and peppers, store in a bottle, and use as needed.
Lei Gong said: When using elephant gallbladder (Xiang Dan), do not use mixed or impure ones. The dried specimen has green bamboo-like patterns on its surface, is smooth and fine, with a slightly sweet taste. Do not pound it together with other herbs initially. Pound this herb alone into powder first; after all other herbs are powdered, mix it into the prescription. This substance comes from white elephants killed by Hu people; the gallbladders are dried and transported to Hanzhong.
Lei Gong said: When using deer antler (Lu Rong), select those still attached to the head, saw off sections three cun long, and soak them in fast-flowing water in a container for one hundred days. Remove, shave off the rough outer layer with a knife, and wipe clean with cloth to remove scale. Then boil in alkali and vinegar for seven days, continuously adding vinegar without letting the fire go out. Do not apply heat during Xu hour (7-9 PM); cook only from Zi hour (11 PM-1 AM) to Xu hour. When done, the antler becomes white and soft like powder, then grind finely into powder. Subsequently, boil the gelatinous part with non-grain ash wine (Wu Hui Jiu), dry in shade, shave again, re-grind, and sieve for use. For every ten liang of preparation, use one yi (approx. 24 jin) of non-grain ash wine, boil until dry.
Lei Gong said: When using [herb name missing in original], first soak in pig lard (Zhu Zhi) overnight. The next morning, remove and roast over willow wood fire until blistered, then grind finely for use.
Lei Gong said: This is whey (Lao Zhi Jiang). When using, filter repeatedly through multiple layers of cotton cloth, boil two or three times in a copper vessel, and then use.
Lei Gong said: Regarding chicken eggs (Ji Zi), if urgently needed, do not break them casually. If incubation has reached twenty-one days, the embryo may have formed inside; breaking an empty shell renders it useless. Naturally ruptured eggs should also be discarded.
Lei Gong said: When refining honey (Feng Mi), one jin yields only twelve and a half liang or less. If the heat is insufficient or excessive, the result is unusable.
Lei Gong said: There are stone oyster (Shi Mu Li), stone fish oyster (Shi Yu Li), and true sea oyster (Zhen Hai Mu Li). Stone oysters have large backs, small shells resembling sand/stone, looking like oysters but round like turtle shells. Sea oysters can be used, but men must not take them as they cause loss of facial hair. True oysters are processed by roasting until white (Huo Pao Bai Pao) and tested with a touchstone; marks appear easily, confirming authenticity. Wan Nian Po (Mythical Amber/Polymer) is described as having miraculous effects. For processing, take twenty specimens, boil in running east-flowing water with one liang of salt for one fu shi (approx. 2-4 hours). Then, burn in fire until red hot. Finally, grind in a mortar into powder for use.
