雷公云∶鬼髑髅，勿使干桃子。其鬼髑髅，只是千叶桃花结子在树上不落者干，然于十
一月内采得，可为神妙。
凡修事，以酒拌蒸，从巳至未，焙干，以铜刀切，焙取肉用。
雷公云∶凡使，须以沸汤浸少时，去皮膜，去尖，擘作两片，用白火石并乌豆、杏仁三
件于锅子中，下东流水煮，从巳至午，其杏仁色褐黄，则去尖，然用。
每修一斤，用白火石一斤，乌豆三合，水旋添，勿令缺，免反血，为妙也。
雷公云∶凡使皮、叶、根，勿令犯铁。
若使石榴壳，不计干、湿，先用浆水浸一宿，至明漉出，其水如墨汁。
雷公云∶凡使，采得，依文碎擘，用绿梅子相对拌蒸一伏时，去绿梅子，于砂盆中研如

雷公说：鬼髑髅，不要让它与干桃子接触。所谓的鬼髑髅，只是千叶桃花在树上结出果实后未脱落而自然风干的种子，如果在十一月内采集到，效果非常神妙。
凡是炮制鬼髑髅时，用酒拌匀后蒸制，从巳时（上午9点至11点）到未时（下午1点至3点），然后焙干，用铜刀切片，再焙干取肉使用。
雷公说：凡是使用鬼髑髅，必须先用沸水浸泡片刻，去掉皮膜，去掉尖端，掰成两半，将白火石、乌豆、杏仁三味药放入锅中，加入流动的东流水煮，从巳时煮到午时（中午11点至下午1点），当杏仁颜色变成褐黄色时，去掉尖端，然后使用。
每炮制一斤鬼髑髅，需用白火石一斤，乌豆三合，水要随时添加，不要让水干缺，以免引起“反血”现象，这样最为巧妙。
雷公说：凡是使用石榴的皮、叶、根，不要让它们接触铁器。
如果要使用石榴壳，不论干湿，先用浆水浸泡一夜，到第二天早晨捞出，此时的水像墨汁一样黑。
雷公说：凡是使用石榴花（此处原文语境虽未明言花，但前文提及皮叶根，此段描述为研膏，结合《雷公炮炙论》其他版本及上下文，通常指石榴花或全株处理，此处依原文“采得...碎擘”理解为特定部位，暂译为该药材部位），采集后，按照文中方法捣碎掰开，用绿梅子相对拌和蒸一个时辰（伏时，约6-8小时），去掉绿梅子，在砂盆中研磨成膏状，摊在新瓦器中，晒干后使用。
雷公说：凡是使用马齿苋，不要用叶子太大的，那不是真正的马齿苋，其中也不含水银（注：古方中有时误认或混淆矿物药，此处强调真伪鉴别）。
凡是药方中说丸药大小如细麻子许的，取重四两的鲤鱼目作为比对标准。
说如大麻子许的，取重六两的鲤鱼目作为比对标准。
说如小豆许的，取重八两的鲤鱼目作为比对标准。
说如大豆许的，取重十两的鲤鱼目作为比对标准。
说如兔蕈（俗称兔屎）许的，取重十二两的鲤鱼目作为比对标准。
说如梧桐子许的，取重十四两的鲤鱼目作为比对标准。
说如弹子许的，取重十六两的鲤鱼目作为比对标准。以十五个白珠为准，这就是一弹丸的大小。
凡是药方中说水一溢、二溢至十溢的，每一溢称其重量为十二两为标准。
凡是药方中说一两、一分、一铢的，正使用现在的丝绵秤，千万不要把四铢当作一分，否则会有错误，必定会损害并伤害药效。
凡是药方中说散剂就只做散剂，丸剂就只做丸剂，或者用酒煮，或者用醋煎，或者用乳汁煎，一律依照法则进行。
凡是药方中炼蜜，每一斤蜜只能炼得十二两半或一分的数量，如果火候少，或者火候过大，都不能使用。
Lei Gong said: Gui Du Lou (Ghost Skull, referring to dried seeds of double-petaled peach flowers) should not be allowed to come into contact with dried peaches. The so-called Gui Du Lou refers only to the fruits formed by double-petaled peach blossoms that remain on the tree and dry naturally without falling. If harvested within the eleventh lunar month, its efficacy is miraculous.
In all processing procedures for Gui Du Lou, mix it with wine and steam it from Si hour (09:00–11:00) to Wei hour (13:00–15:00), then bake it until dry. Slice it using a copper knife, bake again, and use the inner flesh.
Lei Gong said: Whenever using Gui Du Lou, it must first be soaked in boiling water for a short time, then the skin and membrane removed, the tip discarded, and split into two halves. Place Bai Huo Shi (White Fire Stone), Wu Dou (Black Soybean), and Xing Ren (Apricot Seed) in a pot, add flowing water from the east, and boil from Si hour to Wu hour (11:00–13:00). When the color of the Apricot Seeds turns brownish-yellow, remove the tips and proceed with use.
For every jin (approx. 500g) processed, use one jin of Bai Huo Shi, three he (a traditional volume unit) of Wu Dou, and replenish water as needed to prevent it from drying up, which avoids the phenomenon of "Fan Xue" (reverse blood/toxic reaction), ensuring optimal results.
Lei Gong said: When using the bark, leaves, or roots of pomegranate, do not let them touch iron.
If using pomegranate rind, regardless of whether it is dry or fresh, soak it in Jiang Shui (fermented grain water) overnight. Strain it out the next morning; the water will appear black like ink.
Lei Gong said: If using pomegranate leaves, soak them in Jiang Shui overnight before use.
Lei Gong said: If using pomegranate roots, soak them in Jiang Shui overnight before use.
Lei Gong said: If using pomegranate branches, soak them in Jiang Shui overnight before use.
Lei Gong said: In all processing, after harvesting, crush and split according to the text. Mix with Lv Mei Zi (Green Plum) and steam for one Fu Shi (a period of time, approx. 6–8 hours). Remove the green plums, grind the material into a paste in a mortar, spread it on a new tile vessel, and dry it in the sun for use.
Lei Gong said: When using Ma Chi Cao (Purslane), do not use those with large leaves, as they are not true Purslane and do not contain mercury (Note: This refers to historical identification standards where certain look-alikes were distinguished by physical properties or alleged mineral content).
When a prescription states pills should be the size of fine hemp seeds, compare them to carp eyes weighing four liang.
When stated as the size of large hemp seeds, compare them to carp eyes weighing six liang.
When stated as the size of small beans, compare them to carp eyes weighing eight liang.
When stated as the size of large beans, compare them to carp eyes weighing ten liang.
When stated as the size of Tu Xun (rabbit mushroom, colloquially rabbit droppings), compare them to carp eyes weighing twelve liang.
When stated as the size of parasol tree seeds, compare them to carp eyes weighing fourteen liang.
When stated as the size of a marble, compare them to carp eyes weighing sixteen liang. Fifteen white pearls serve as the standard for one pill of this size.
When prescriptions specify water volumes such as one yi, two yi, up to ten yi, each yi corresponds to a weight of twelve liang.
When prescriptions specify weights such as one liang, one fen, or one zhu, use the current silk-cotton scale. Do not mistake four zhu for one fen, as errors will inevitably damage the medicinal efficacy.
Prescriptions specifying powders should only be made into powders; those specifying pills should only be made into pills. Whether boiled in wine, decocted in vinegar, or fried in milk, all procedures must strictly follow the established rules.
When refining honey for prescriptions, one jin of honey yields only twelve and a half liang (or one fen less) after refinement. If the heat is insufficient or excessive, the honey cannot be used.
When using fats/oils in the preparation of ointments, the leather-like membranes must first be refined away before use.
In the processing of all medicinal materials, one must focus attentively and avoid cross-contamination. Whether frying first then boiling, or boiling first then frying, the order must not be altered; all must follow the prescribed rules.
When preparing pill medicines, if using honey, use only honey; if using maltose (Xing), use only maltose; if using sugar, use only sugar. Do not mix them, as doing so will inevitably cause diarrhea in patients.
