雷公云∶水中生火，非KT 髓而莫能。
海中有兽，名曰KT ，以髓入在油中，其油沾水，水中生火，不可救之，用酒喷之即
。
勿于屋下收。
雷公云∶凡使，须去蒂并向里子后，取皮，用茱萸同于 上缓炒，待茱萸微黄黑，即去
茱萸，取草豆蔻皮及子，杵用之。
雷公云∶凡使，勿用柚皮、皱子皮，其二件用不得。
凡修事，须去白膜一重，细锉，用鲤鱼皮裹一宿，至明，出，用。
其橘皮，年深者最妙。
雷公云∶凡使，用东流水淘去黄叶并皮、蒂，尽了，用酒蒸一宿，以东流水淘两遍，又
晒干方用为妙也。
雷公云∶凡使，有四件。八棱者，两头尖、色紫黑者，又呼胡麻，并是误也；其巨胜有
七棱，色赤、味涩酸是真；又呼乌油麻，作巨胜，亦误。
若修事一斤，先以水淘，浮者去之，沉者漉出，令干，以酒拌蒸，从巳至亥，出，摊晒
干；于臼中，舂令粗皮一重尽；拌小豆相对同炒，小豆熟即出，去小豆用之。上有薄皮，去
、留用，力在皮壳也。
雷公云∶凡使，勿用白瓜蒂，要采取青绿色瓜，待瓜气足，其瓜蒂自然落在蔓茎上。
夫采得，未用时，使榔榔叶裹，于东墙有风处挂令吹干用。
雷公云∶瓜子凡使，勿用瓜子实，恐误。
夫采得后，便于日中曝令内外干，便杵，用马尾筛筛过，成粉末了用。
雷公说：水中生火，除了瓜子（此处指代某种特定药材，原文作“KT髓”，疑为传抄错误或特指物）之外，没有谁能做到。
海中有种兽类，名叫瓜子（KT），它的骨髓存在于油脂中，这种油沾到水里，就能在水中起火，无法用水扑灭，只有用酒喷洒才能熄灭。
不要在屋檐下收集（处理）。
雷公说：凡是使用瓜子，必须去掉蒂部并向内包裹的子实部分，取外皮，与吴茱萸一起在火上缓慢炒制，等到吴茱萸微微变黄黑色时，就去掉吴茱萸，取出瓜子皮及子实，捣碎后使用。
雷公说：凡是使用瓜子，不要使用柚皮和皱皮（可能指其他类似名称的果皮），这两种不能使用。
凡是炮制加工，必须去掉一层白色的膜，细细切碎，用鲤鱼皮包裹一夜，到第二天早上取出，然后使用。
其中的橘皮，年份越久远的越好。
雷公说：凡是使用瓜子，要用东流水淘洗，去掉黄叶以及皮、蒂，淘洗干净后，用酒蒸一夜，再用东流水淘洗两遍，晒干后才算最好。
雷公说：凡是使用瓜子，有四类情况需要注意。有八棱的，两头尖、颜色紫黑的，又被称为胡麻，这都是错误的叫法；真正的巨胜（即芝麻）有七棱，颜色赤红、味道涩酸；又被称为乌油麻而当作巨胜使用的，也是错误的。
如果炮制一斤，先用水淘洗，浮起来的去掉，沉下去的捞出来，晾干，用酒拌匀蒸制，从巳时到亥时（共十个小时），取出摊开晒干；在石臼中舂捣，直到外层粗皮完全去除；拌入小豆相对同炒，小豆炒熟后就取出，去掉小豆使用。上面有一层薄皮，要去掉（或保留，原文“去、留用”语意稍显模糊，结合上下文“力在皮壳也”，通常指保留有效部位或去除杂质，此处依字面译为去掉或保留备用，但根据“力在皮壳”，倾向于强调皮壳的作用，故译为去掉杂质保留皮壳或视具体情况而定，此处直译：去掉...保留使用），药效在于皮壳。
雷公说：凡是使用瓜子，不要用白瓜蒂，要采摘青绿色的瓜，等到瓜气充足，其瓜蒂自然会落在藤蔓茎上。
采集回来后，未使用时，用榔榔叶包裹，挂在东墙有风的地方吹干使用。
雷公说：瓜子凡是要使用时，不要用瓜子仁（实），恐怕会弄错。
采集回来后，便于在阳光下暴晒，使内外都干燥，然后捣碎，用马尾筛筛过，成为粉末后使用。
Lei Gong said: Fire generating from water, apart from [Guizi Sui / KT Marrow] (a specific medicinal material, likely a textual corruption or specific term), no one else can achieve it.
There is a beast in the sea named [Guizi / KT]. Its marrow exists within its oil. When this oil touches water, it generates fire on the water surface and cannot be extinguished by water; only spraying with wine can put it out.
Do not collect (process) under the eaves of a house.
Lei Gong said: Whenever using [Guizi], one must remove the calyx and the inner seed portion, taking only the peel. Stir-fry it slowly over heat together with Evodiae Fructus (Wuzhuyu). When the Evodiae Fructus turns slightly yellowish-black, remove the Evodiae Fructus. Take the peel and seeds of Amomi Fructus Rotundus (Caodoukou), pound them, and use them.
Lei Gong said: Whenever using [Guizi], do not use Pomelo Peel (Youpi) or wrinkled peel (Zhouzi); these two types are unusable.
Whenever processing, one must remove a layer of white membrane, finely chop it, wrap it in Carp Skin (Liyupi) for one night. The next morning, take it out and use it.
Among Tangerine Peel (Jupi), the older the age, the better.
Lei Gong said: Whenever using [Guizi], wash it with flowing water from the east to remove yellow leaves, peels, and calyces until clean. Then steam it with wine for one night. Wash it twice more with flowing water from the east, dry it in the sun, and then it is best to use.
Lei Gong said: Whenever using [Guizi], there are four categories to distinguish. Those with eight ridges, pointed at both ends, and purple-black in color, also called Sesame (Huma), are mistaken identities. The true Jusheng (Sesamum indicum, Black Sesame) has seven ridges, is reddish in color, and has a astringent and sour taste. Calling it Wuyouma (Black Oil Sesame) and treating it as Jusheng is also an error.
If processing one jin (approx. 500g), first wash with water. Discard floating ones, retrieve sunken ones, and let them dry. Mix with wine and steam from Si hour (9-11 AM) to Hai hour (9-11 PM). Take out and spread to dry. Pound in a mortar until the outer coarse skin is completely removed. Stir-fry together with Adzuki Beans (Xiaodou). When the beans are cooked, take out, discard the beans, and use the seeds. There is a thin skin on top; remove [impurities/keep as per efficacy in shell], as the potency lies in the shell.
Lei Gong said: Whenever using [Guizi], do not use White Melon Calyx (Baiguadi). One should harvest green melons. Wait until the melon's qi is sufficient, so that the calyx naturally falls onto the vine stem.
After harvesting, before use, wrap them in Langlang Leaves (Langlangye). Hang them in a windy place on the east wall to dry by air.
Lei Gong said: Whenever using Guazi (Melon Seeds), do not use the kernel/seed meat (Shi), lest confusion arise.
After harvesting, expose them to the sun to dry thoroughly inside and out. Then pound them. Sieve through a horse-hair sieve until they become powder, and then use.
