雷公云∶凡使，勿误用野狼毒，缘真似防葵，而验之有异，效又不同，切须审之，恐误疾
人。其防葵在蔡州沙土中生，采得二十日便 ，用之唯轻为妙。
凡欲使，先须拣去 末，后用甘草汤浸一宿，漉出，曝干，用黄精自然汁一、二升拌，

雷公云∶凡使，茎长软、皮赤、黄髭须。出在平州平县，即今银州银县也。西畔生处，
多有白鹤、绿鹤于此翔处，是柴胡香直上云间，若有过往闻者，皆气爽。
凡采得后，去髭并头，用银刀削上赤薄皮少许，却，以粗布拭了，细锉用之。
勿令犯火，立便无效也。
雷公云∶凡使，采得后，细锉，拌淫羊藿， 二日后，曝干，去淫羊藿用。免烦人心。
雷公云∶凡使，采得了，刀刮上粗皮一重了，用黄精自然汁浸一宿，出，曝干，细锉，

雷公云∶凡使，其香是芦蔓根条，左盘旋。采得二十九日，方硬如朽骨，硬碎。其有芦
头丁盖子色青者，是木香神也。
雷公云∶凡使，勿用平田生二、三纪内者，要经十纪者，山中生，皮赤，四面有髭生者
妙。
若采得，用铜刀削去上赤皮，洗去涎，蒸用。
雷公说：凡是使用防葵时，不要误用野狼毒，因为真品与伪品外形相似，但验证方法不同，疗效也截然不同，必须仔细辨别，恐怕误治病人。防葵生长在蔡州的沙土中，采得后放置二十天便干燥，使用时以质地轻者为妙。
凡是准备炮制防葵，先须拣去细小的根须末梢，然后用甘草汤浸泡一夜，捞出，晒干，再用黄精的自然汁一、二升拌匀，放入土器中炒至黄精汁被吸尽。
雷公说：凡是使用柴胡，其茎细长柔软，表皮呈红色，有黄色的根须。产于平州平县，即现在的银州银县。在西侧生长的地方，多有白鹤、绿鹤在此飞翔栖息，柴胡的香气直冲云霄，如果有过往的人闻到，都会感到神清气爽。
凡是采得柴胡后，去掉根须和头部，用银刀削去少许红色的薄皮，然后，用粗布擦拭干净，细切后使用。不要让柴胡接触火，否则立刻就会失效。
雷公说：凡是使用淫羊藿，采得后，细切，拌入淫羊藿（此处原文可能有误，通常指拌入其他辅料或自身处理，但依原文翻译），两天后，晒干，去掉淫羊藿（此处语境存疑，可能指去掉辅料或特定部位）使用。以免使人烦乱心神。
雷公说：凡是使用薯蓣，采得后，用刀刮去一层粗糙的外皮，用黄精的自然汁浸泡一夜，取出，晒干，细切，蒸制，然后，晒干使用。
雷公说：凡是使用人参，必须是一株有九片叶子，内有花蕊茎，可长到一尺二寸长的。连同花蕊、叶子、根部一起，去掉泥土，称重有一镒重的，药力完整，可以使用。使用叶子时，不要使用花蕊茎。
如果要使用叶子，细切，在新瓦上摊开晾干使用。
雷公说：凡是使用木香，其香气来自芦蔓根条，向左盘旋生长。采得后经过二十九天，才变得坚硬如朽骨，易碎。其中有芦头丁盖子颜色青色的，是木神（优质木香）。
雷公说：凡是使用某药材（原文未指名，结合上下文可能是前文提到的某种根茎类），不要用平原田地中生长两、三十年内的，要选用生长了六十年（十纪）的，山中生长的，表皮红色，四面生有根须的为好。
如果采得，用铜刀削去上面的红皮，洗去粘液，蒸制后使用。
Lei Gong said: When using Fangkui (Adenophorae Radix), do not mistakenly use Yelangdu (Stellerae Chamaejasmi Radix), as the genuine and fake varieties resemble each other, but their verification methods differ, and their therapeutic effects are distinct. One must examine them carefully to avoid misdiagnosing or mistreating patients. Fangkui grows in the sandy soil of Caizhou. After harvesting, it should be dried for twenty days; when used, those with a lighter texture are superior.
When preparing Fangkui, first remove the fine rootlets. Then, soak it in Gancao Tang (Licorice Decoction) overnight, drain, and dry in the sun. Mix it with 1–2 sheng of Huangjing natural juice (Rhizoma Polygonati Juice), and stir-fry in an earthenware vessel until the Huangjing juice is fully absorbed.
Lei Gong said: When using Chaihu (Bupleuri Radix), the stem is long and soft, the skin is red, and there are yellow rootlets. It originates from Pingzhou Pingxian, which is now Yinxian in Yinzhou. In areas where it grows on the western side, white cranes and green cranes often fly and roost there. The fragrance of Chaihu rises straight into the clouds; anyone passing by who smells it will feel refreshed and clear-headed.
After harvesting Chaihu, remove the rootlets and the head. Use a silver knife to shave off a small amount of the thin red skin. Then, wipe it clean with coarse cloth, finely slice it, and use it. Do not allow it to come into contact with fire, or it will lose its efficacy immediately.
Lei Gong said: When preparing Yin Yang Huo (Epimedii Folium), after harvesting, finely slice it, mix it with Yin Yang Huo (note: text implies mixing with itself or a specific preparation method, literally "mix with Epimedii Folium"), leave it for two days, then dry in the sun and remove the Yin Yang Huo (note: contextually ambiguous, likely referring to removing the processing medium or specific parts) before use. This prevents causing mental restlessness.
Lei Gong said: When preparing Shuyu (Dioscoreae Rhizoma), after harvesting, scrape off one layer of the rough outer skin with a knife. Soak it overnight in Huangjing natural juice (Rhizoma Polygonati Juice). Take it out, dry in the sun, finely slice it, steam it, and then dry it in the sun for use.
Lei Gong said: When using Renshen (Ginseng Radix et Rhizoma), select a plant that has nine leaves per cluster, with a flower stalk that can grow up to one chi two cun long. Weigh the whole plant including the flower stalk, leaves, and roots after cleaning off the soil. If it weighs one yi, its medicinal power is complete and suitable for use. When using the leaves, do not use the flower stalks.
If using the leaves, finely slice them, spread them out on a new tile to dry, and then use them.
Lei Gong said: When using Muxiang (Aucklandiae Radix), its aroma comes from the reed-like vine roots that spiral to the left. After harvesting, let it age for twenty-nine days until it becomes hard like rotten wood and brittle. Those with a blue-green color at the "reed head" cap are considered high-quality Muxiang (Shen).
Lei Gong said: When using a certain herb (name omitted in source, likely referring to a root growing in plains vs. mountains), do not use plants grown in flat fields for only two to three ji (decades). Select those that have grown for ten ji (sixty years), preferably grown in the mountains, with red skin and rootlets growing all around.
If harvested, use a copper knife to peel off the red outer skin, wash away the saliva-like mucus, steam it, and then use it.
