雷公云∶凡使，采得了，去上皮一重，便劈破，去心。用柳木甑烧柳木柴蒸一伏时，洒
酒令遍，更添火蒸；出，曝，去地二尺已来作小架，上铺天门叶，将蒸了天门冬摊令干用。
雷公云∶凡使，须去头、尾尖处。其头、尾吐人。
凡修事，每斤皆长三寸锉，劈破作六、七片，使瓷器中盛，用酒浸蒸，从巳至午，出，
曝干，细锉。
使一斤，用酥七两涂上，炙酥尽为度。
又，先炮令内外赤黄用良。
雷公云∶凡使，采生地黄，去白皮，瓷埚上柳木甑蒸之，摊令气歇，拌酒再蒸，又出令
干。
勿令犯铜、铁器，令人肾消，并白髭发，男损荣，女损卫也。
雷公云∶凡使，勿用天碧草子，其样真相似，只是天碧草子味酸涩并粘，不入药用。其
菟丝子禀中和凝正阳气受结，偏补人卫气，助人筋脉，一茎从树感枝成，又从中春上阳结实
，其气大小，受七镒二两。
凡修事，全采得，出粗薄壳，了，用苦酒浸二日，漉出，用黄精自然汁浸一宿，至明，
微用火煎至干，入臼中，热烧铁杵，一去三千余杵，成粉用。
苦酒并黄精自然汁与菟丝子相对用之。
雷公云∶凡使，去头并尘土，了，用黄精自然汁浸一宿，漉出，细锉，焙干用之。
雷公云∶凡使，勿用钩吻并黄精，其二物相似葳蕤，只是不同，有误疾人。葳蕤节上有
毛，茎斑，叶尖处有小黄点。
凡修事，采得，先用竹刀刮上节皮，了，洗净，却，以蜜水浸一宿，蒸，了，焙干用。
雷公说：凡是使用天门冬，采挖回来后，去掉最外层的表皮一层，然后剖开，去除心部。用柳木做的蒸笼，以柳木柴为燃料，蒸一个时辰（十二小时），喷洒酒使其均匀，再增加火力继续蒸；取出后，在阳光下晾晒，距离地面约二尺处搭建小架子，上面铺上天门冬的叶子，将蒸过的天门冬摊在上面晾干备用。
雷公说：凡是使用天门冬，必须去掉头部和尾部的尖端部分。因为头、尾部分会引起呕吐。
凡是炮制加工，每斤药材都要切成三寸长的小段，剖开后分成六、七片，放入瓷器中，用酒浸泡并蒸制，从巳时到午时，取出后晒干，再细切。
使用一斤药材，需用酥油七两涂抹其上，炙烤至酥油完全被吸收为止。
另外，先将其炮制至内外呈赤黄色，效果更佳。
雷公说：凡是使用生地黄，去掉白色外皮，放在瓷锅上的柳木蒸笼中蒸制，摊开让其热气散尽，拌入酒再次蒸制，再取出晾干。
不要让生地黄接触铜、铁器皿，否则会导致肾气消损，并使胡须头发变白，男子损伤营气，女子损伤卫气。
雷公说：凡是使用菟丝子，不要使用天碧草子，它们的形状非常相似，只是天碧草子的味道酸涩且粘腻，不能入药。菟丝子禀受中和之气，凝聚纯正阳气而结籽，偏重于补益人的卫气，辅助人体筋脉，它的一根茎依附树木感应枝条而成，又在仲春时节接受阳气结实，其重量大小，总计受气七镒二两（注：此处原文数据可能有误或特指某种计量，按字面翻译）。
凡是炮制加工，全部采挖回来，去掉粗糙的外壳，用苦酒（醋）浸泡两天，滤出，用黄精的自然汁液浸泡一夜，到第二天早晨，用微火煎至干燥，放入石臼中，用烧热的铁杵捣击三千多次，制成粉末使用。
苦酒和黄精自然汁液是与菟丝子配合使用的辅料。
雷公说：凡是使用黄精，去掉头部和尘土后，用黄精的自然汁液浸泡一夜，滤出，细切，焙干后使用。（注：此处原文“用黄精自然汁浸...用之”逻辑上似有重复或指代其他类似药材，但依原文直译）
雷公说：凡是使用葳蕤（玉竹），不要使用钩吻和黄精，这三种东西外形相似，只是有所不同，如果用错会延误病人的病情。葳蕤的节上有毛，茎上有斑纹，叶尖处有小黄点。
凡是炮制加工，采挖回来后，先用竹刀刮去节上的皮，洗净，然后用蜜水浸泡一夜，蒸制后，焙干使用。
Lei Gong said: When using Asparagi Radix (Tianmendong), after harvesting, remove the outermost layer of the epidermis, split it open, and remove the core. Steam it in a willow-wood steamer fueled by willow wood for one double-hour (12 hours), sprinkle wine evenly over it, and steam again with increased heat; take it out, sun-dry it, place it on a small rack about two chi above the ground lined with leaves of Asparagus cochinchinensis, spread the steamed Asparagi Radix to dry for use.
Lei Gong said: When using Asparagi Radix, the head and tail tips must be removed. The head and tail parts can induce vomiting.
For processing, each jin (approx. 500g) should be cut into three-cun long segments, split into six or seven slices, placed in a porcelain vessel, soaked and steamed in wine from Si hour to Wu hour, taken out, dried, and finely sliced.
For every jin of the herb, apply seven liang of su (animal fat/butter), roast until the su is completely absorbed.
Alternatively, process it first until both the inside and outside are reddish-yellow for better efficacy.
Lei Gong said: When using raw Rehmanniae Radix (Shengdihuang), remove the white skin, steam it in a willow-wood steamer placed on a porcelain pot, spread it out to let the heat dissipate, mix with wine, steam again, and then take out to dry.
Do not allow it to come into contact with copper or iron vessels, as this will cause kidney qi depletion, whiten the beard and hair, damage Ying Qi (Nutritive Qi) in men, and Wei Qi (Defensive Qi) in women.
Lei Gong said: When using Semen Cuscutae (Tusizi), do not use seeds of Tianbi Cao (likely referring to a look-alike plant). Although they look very similar, the taste of Tianbi Cao seeds is sour, astringent, and sticky, making them unsuitable for medicinal use. Semen Cuscutae inherits neutral qi, condenses pure yang qi to form seeds, predominantly tonifies the body's Wei Qi, and assists the sinews and vessels. Its single stem grows by sensing and attaching to tree branches, and it forms fruit by receiving yang qi in mid-spring. Regarding its weight/energy reception, it involves seven yi and two liang (Note: This appears to be a specific traditional measurement or textual anomaly, translated literally).
For processing, harvest completely, remove the coarse outer shell, soak in kujiu (vinegar) for two days, drain, soak overnight in the natural juice of Polygonati Rhizoma (Huangjing), and by morning, simmer gently over low fire until dry. Place in a mortar, pound with a heated iron pestle more than three thousand times to make powder for use.
Kujiu (vinegar) and the natural juice of Polygonati Rhizoma are used in conjunction with Semen Cuscutae.
Lei Gong said: When using Polygonati Rhizoma (Huangjing), after removing the head and dirt, soak it overnight in the natural juice of Polygonati Rhizoma itself, drain, slice finely, bake until dry, and use.
Lei Gong said: When using Ophiopogonis Radix (Weirui/Yuzhu), do not use Gouwen (Aconitum carmichaelii side roots) or Huangjing, as these three substances look similar but are different; using the wrong one may harm the patient. Weirui has hairs on its nodes, mottled stems, and small yellow spots at the leaf tips.
For processing, after harvesting, first scrape off the node skin with a bamboo knife, wash clean, then soak in honey-water overnight, steam, bake until dry, and use.
