雷公云∶凡使，勿用色青并底白者。
凡使，先单捣令细，三度筛过了，又入钵中研之，然后将盐汤飞过，浪干。每修事白垩
二两，用白盐一分，投于斗水中，用铜器物内沸十余沸了，然后用此沸了水飞过白垩，免结
涩人肠也。
雷公云∶石髓铅，即自然铜也。凡使，勿用方金牙，其方金牙真似石髓铅，若误饵，吐
煞人。其石髓铅色似干银泥，味微甘。
如采得，先捶碎，同甘草汤煮一伏时，至明漉出，摊令干，入臼中捣了，重筛过，以醋
浸一宿，至明，用六一泥泥瓷合子，约盛得二升已来，于文武火中养三日夜，才干，便用盖
盖
若修事五两，以醋两镒为度。
雷公云∶凡使，先须细认，勿误用。有乌头、乌喙、天雄、侧子、木鳖子。乌头少有茎
苗，长身乌黑，少有旁尖；乌喙皮上苍，有大豆许者孕八、九个周遭，底陷，黑如乌铁；天
雄身全矮，无尖，周匝四面有附孕十一个，皮苍色，即是天雄；并得侧子，只是附子旁，有
小颗附子如枣核者是；木鳖子只是诸喙、附、雄、乌、侧中毗 者，号曰木鳖子，不入药中
用，若服，令人丧目。若附子，底平、有九角、如铁色，一个个重一两，即是气全，堪用。
屋下午地上掘一坑，可深一尺，安于中一宿，至明取出，焙干用。
夫欲炮者，灰火勿用杂木火，只用柳木最妙。
若阴制使，即生去尖皮底，了，薄切，用东流水并黑豆浸五日夜，然后漉出，于日中晒
令干用。
凡使，须阴制，去皮尖了，每十两，用生乌豆五两，东流水六升。
凡是使用，先单独捣碎使其变细，经过三次筛选后，再放入钵中研磨，然后用盐水溶液漂洗，晾干。每次炮制二两白垩时，用一分白盐，投入一斗水中，在铜器内煮沸十余次，然后用这煮沸的水来漂洗白垩，以避免其导致肠道干涩结滞。
雷公说：石髓铅，就是自然铜。凡是使用，不要选用带有方形金牙的，那方形金牙看起来很像石髓铅，如果误服，会致人呕吐甚至死亡。石髓铅的颜色像干燥的银泥，味道微甜。
如果采集到，先将其捶碎，与甘草汤一起煮一个时辰（约两小时），等到第二天捞出，摊开晾干，放入臼中捣碎，再次仔细筛选，用醋浸泡一夜，到第二天，用六一泥涂抹瓷盒，大约能盛装二升左右的药料，在文火和武火之间养护三昼夜，直到完全干燥，然后盖上盖子。
如果要炮制五两，以两镒醋为限度。
雷公说：凡是使用（某种药材，原文此处似缺主语，结合上下文推测可能指代前文或特定矿物，但按字面翻译），必须远离烟火，放置在高大殿堂之上。拂去灰尘，筛选后使用。
雷公说：凡是使用，必须先仔细辨认，不要误用。有乌头、乌喙、天雄、侧子、木鳖子。乌头少有茎叶苗穗，身形修长乌黑，少有旁生的尖角；乌喙表皮呈苍青色，有大豆大小的孕育物八九个环绕周围，底部凹陷，黑得像乌鸦的铁色；天雄身形完整而矮小，没有尖角，四周四面有附生的孕育物十一个，皮色苍青，这就是天雄；并得到侧子，只是附子旁边有小颗附子像枣核一样的就是；木鳖子只是那些喙、附、雄、乌、侧中毗连者，号称木鳖子，不入药用，如果服用，会使人失明。如果是附子，底部平整、有九个角、像铁的颜色，一个个重一两，那就是气机完备，可以使用。在屋下午时的地上挖一个坑，深约一尺，将药安放在其中过夜，到第二天取出，焙干后使用。
Lei Gong said: When using (Bai E, White Kaolin), do not select those that are greenish in color and white at the base.
When using, first crush it alone until fine, sift it three times, then grind it in a mortar. Subsequently, wash it with salt water solution and dry it. For every two taels of Bai E to be processed, use one fen of white salt, add it to one dou of water, boil it in a copper vessel for more than ten boils, and then use this boiled water to wash the Bai E, thereby preventing it from causing intestinal dryness and constipation.
Lei Gong said: Shi Sui Qian (Stone Marrow Lead) is Zi Ran Tong (Natural Copper). When using, do not select those with square golden teeth; these square golden teeth resemble Shi Sui Qian closely. If mistakenly ingested, they can induce vomiting and death. Shi Sui Qian resembles dried silver mud in color and has a slightly sweet taste.
If collected, first crush it by pounding, then decoct it with Gan Cao Tang (Licorice Decoction) for one fu shi (a four-hour period or approx. two hours depending on context, traditionally 12 double-hours but here likely shorter given "to tomorrow"). Strain it out the next day, spread it to dry, pound it in a mortar, sieve it again, soak it in vinegar overnight. The next day, coat a porcelain jar with Liu Yi Ni (Six-One Mud), fill it with about two sheng of material, and nurture it over gentle and strong fires for three days and nights until completely dry, then cover it.
If processing five taels, use two yi of vinegar as the limit.
Lei Gong said: When using, keep it far from smoke and fire, place it in high halls. Brush off dust, sieve, and use.
Lei Gong said: When using, must carefully identify to avoid misuse. There are Wu Tou (Aconiti Radix), Wu Hui (Aconiti Radix Cum Radicula), Tian Xiong (Aconiti Lateralis Radix Preparata), Ce Zi (Aconiti Lateralis Radix), and Mu Bie Zi (Strychni Semen). Wu Tou has few stem leaves, long body, black, with few lateral points; Wu Hui has a bluish-gray skin, with eight or nine soybean-sized buds surrounding it, depressed bottom, black like iron; Tian Xiong is complete but short, without points, with eleven lateral buds around all sides, bluish-gray skin, this is Tian Xiong; Ce Zi is obtained, which is just small lateral buds like jujube pits attached to the side of Fu Zi (Aconiti Lateralis Radix Preparata); Mu Bie Zi refers to those among the Hui, Fu, Xiong, Wu, Ce that are connected, called Mu Bie Zi, not used in medicine; if taken, it causes blindness. If it is Fu Zi, with a flat bottom, nine angles, iron-colored, each weighing one tael, it is qi-complete and usable. Dig a pit one chi deep in the afternoon on the ground under the house, place it inside for one night, take it out the next morning, bake dry, and use.
For roasting, do not use ash fire mixed with miscellaneous wood fire; only willow wood fire is best.
If using the yin-processing method, use raw material, remove tips and bottoms, slice thinly, soak in Dong Liu Shui (East-flowing Water) and Hei Dou (Black Soybeans) for five days and nights, then strain out, sun-dry, and use.
When using, yin-processing is required. After removing skin and tips, for every ten taels of herb, use five taels of raw Wudou (Black Soybeans) and six sheng of Dong Liu Shui (East-flowing Water).
