雷公云∶凡使，多有讹伪。其有三验∶第一验，将半铢安于熟铜器中，一宿至明，沾阿
魏处，白如银，永无赤色；第二验，将一铢置于五斗草自然汁中，一夜至明，如鲜血色；第
三验，将一铢安于柚树上，树立干便是真。
凡使，先于静钵中研如粉了，于热酒器上 过，任入药用。
雷公云∶凡使，采得后，用竹刀劈破，去心皮，花作数十条，于檐下悬，令风吹，待土
干后，却用酒浸一宿，漉出，焙干，细锉用。
忽一窠自有八十三条者，号曰地仙苗。若修事饵之，可千岁也。
雷公云∶凡采得，须去向里裹花蕊壳、并向里实如粟零壳者，并枝、叶用。
凡用，以甘草水浸一宿，却，取款冬花叶相拌 一夜。临用时，即干晒，去两件拌者叶
了用。
雷公云∶凡使，采得后，日干，用铜刀劈破，去骨了，细锉如大豆许，用清酒拌蒸，从
巳至未，出，日干用。
雷公云∶凡使，先去挺，用头醋浸一宿，焙干，以刀刮去皮粟子令净方用，免伤人肺，
令人上气。
雷公云∶凡使，采得后，以刀刮上粗皮，便捣，用生姜自然汁拌之，蒸一日了，出，日
干。
每修事五两，用生姜汁五两，蒸干为度。
雷公说：凡是使用（阿魏），市面上多有伪造。辨别真伪有三条验证方法：第一条，取半铢（古代重量单位）放在熟铜器中，放置一夜直到天亮，沾染阿魏的地方，颜色白得像银子一样，永远不会有红色；第二条，取一铢放在五斗草的自然汁液中，浸泡一夜直到天亮，颜色像鲜血一样红；第三条，取一铢放在柚树上，如果树液干枯后显现出真品特征，便是真的。
凡是要使用时，先在安静的钵中研磨成粉末，然后在热酒器上过滤，任意配入药物中使用。
雷公说：凡是使用（豆蔻），采摘回来后，用竹刀劈开，去掉心皮，将花瓣分成几十条，悬挂在屋檐下，让风吹干，等到泥土干燥后，再用酒浸泡一夜，滤出，焙干，细切后使用。
忽然有一株有八十三条的，称为“地仙苗”。如果经过炮制服用它，可以活到千岁。
雷公说：凡是采摘回来，必须去除包裹花蕊壳、以及向内充实如粟米壳一样的部分，连同枝、叶一起使用。
凡是要使用时，用甘草水浸泡一夜，然后取出，与款冬花叶混合拌和一夜。临用时，立即晒干，去掉两种拌和的叶子后使用。
雷公说：凡是使用（某种药材，原文未指名，据上下文推测可能为另一种药或泛指），采摘回来后，日晒干燥，用铜刀劈开，去掉骨（核心部分），细切成像大豆大小的颗粒，用清酒拌和蒸制，从巳时到未时，取出，日晒干燥后使用。
雷公说：凡是使用（某种药材，原文未指名），先去掉挺（茎干），用头醋浸泡一夜，焙干，用刀刮去像栗子皮一样的粗皮，刮干净后才使用，以免伤害人的肺，导致人气逆上冲。
雷公说：凡是使用（某种药材，原文未指名），采摘回来后，用刀刮去上面的粗皮，随即捣碎，用生姜自然汁拌和，蒸一天后取出，日晒干燥。
每次炮制五两，使用生姜汁五两，蒸至干燥为止。
雷公说：凡是使用（豆蔻），必须用糯米磨成粉，用热水调和包裹住豆蔻，在灰中炮制，等到米团子焦黄熟透，然后取出，去掉米粒，其中含有豆蔻仁，取出来使用。
不要让豆蔻接触铜器。
Lei Gong stated: In general use, there are often forgeries. There are three tests to verify authenticity: The first test is to place half a zhu (an ancient unit of weight) in a pure copper vessel and leave it overnight until dawn; the area where Asafoetida (Asafetida) touches will turn white like silver and never show any red color. The second test is to place one zhu in the natural juice of Wudoucao (Eleutherococcus senticosus) overnight until dawn; it will turn the color of fresh blood. The third test is to place one zhu on a pomelo tree; if the sap dries and reveals the true characteristics, it is authentic.
When preparing for use, first grind it into powder in a quiet mortar, then filter it over a hot wine vessel, and incorporate it into medicinal preparations as needed.
Lei Gong stated: When preparing Cardamom (Doukou), after harvesting, split it open with a bamboo knife, remove the core and skin, separate the petals into dozens of strips, hang them under the eaves to be dried by the wind, wait until the soil moisture is gone, then soak them in wine overnight, drain, bake dry, and finely chop for use.
Occasionally, a single cluster may have eighty-three strips, known as "Dixian Miao" (Seedling of the Earth Immortal). If processed and taken as food/medicine, it is said to grant longevity of a thousand years.
Lei Gong stated: After harvesting, one must remove the husks wrapping the flower stamens and the inner solid parts resembling millet husks, using both the branches and leaves.
For use, soak in Licorice root (Gancao) water overnight, then take out and mix with leaves of Coltsfoot (Kuandonghua) for another night. Before use, sun-dry immediately, remove the mixed leaves, and use the remainder.
Lei Gong stated: For use, after harvesting, sun-dry, split open with a copper knife, remove the core/bone, finely chop to the size of soybeans, mix with clear wine, and steam from Si hour (9-11 AM) to Wei hour (1-3 PM). Take out, sun-dry, and use.
Lei Gong stated: For use, first remove the stalks, soak in first-grade vinegar overnight, bake dry, scrape off the coarse skin resembling chestnut shells until clean before use, to avoid injuring the lungs and causing Qi rebellion (upper rushing Qi).
Lei Gong stated: For use, after harvesting, scrape off the coarse outer skin with a knife, then pound, mix with fresh Ginger (Shengjiang) juice, steam for one day, take out, and sun-dry.
For every five liang processed, use five liang of Ginger juice, steaming until dry.
Lei Gong stated: For use, make glutinous rice flour, knead with hot water to wrap around the Cardamom (Doukou), roast in ashes until the rice ball is scorched yellow and cooked through. Then take out, remove the rice, and use the seeds inside.
Do not allow contact with copper.
