雷公说：凡是使用薏苡仁时，不要选用米形颗粒大且没有味道的。那种米形的颗粒，当时的人称之为粳米。如果是真正的薏苡仁，颗粒较小、颜色青白、味道甘甜，咬在嘴里会黏住牙齿。
如果要用一两薏苡仁，就用二两糯米一同熬煮，等到糯米煮熟后，去掉糯米，只取薏苡仁入药。
雷公说：凡是使用络石藤时，不论用量多少，先将其细切，用酒浸泡一夜，滤出药渣，晒干后即可随意使用。

雷公说：凡是使用石斛时，采摘后先在阴凉处晾干。想要使用时，用铜刀切去须根、泥土和头部，切碎后，放入甘草汤中浸泡一夜，到第二天早晨滤出药渣，晒干后使用。
空腹服用石斛会导致小便失禁，因此不可空腹服用。
雷公说：凡是使用天名精时，要逐一拣除双叶的植株，因为双叶的天名精服用后会伤害人体。必须去除头部和泥土，然后用瓜汁浸泡一夜，到第二天早晨滤出药渣，晒干后使用。
雷公说：凡是使用淫羊藿时，先去除头部和泥土，用酒浸泡一夜，滤出药渣，在阳光下晒干；然后再用酥油蒸制，从巳时到酉时（约上午9点至下午7点），最后慢慢焙干后使用。
石斛能锁住津液，涩滞男子的元气。像这样经过炮制的淫羊藿，服用满一镒（古代重量单位），永远不会有骨痛之症。
雷公说：凡是使用枸杞子时，需要用枸杞子汤浸泡一夜，待其稍微变软后，滤出药渣；然后再用酒浸泡一个时辰（约2小时），再次滤出药渣；最后与菊花一同熬煮，直到变成焦黄色，去掉菊花，用布擦拭干净并晒干后使用。

Lei Gong said: When using Coicis Semen (Yiyiren, 薏苡仁), do not use the large, tasteless grains. These large grains are what people at that time called Jingmi (Japonica Oryzae Semen, 粳米). True Coicis Semen has small grains, is greenish-white in color, tastes sweet, and sticks to the teeth when chewed.
If one ounce of Coicis Semen is required, boil it together with two ounces of Glutinis Oryzae Semen (Jingmi, 糯米) until the glutinous rice is cooked. Discard the glutinous rice and use only the Coicis Semen.
Alternatively, boiling it in salt water constitutes a different special processing method, which is also acceptable.
Lei Gong said: For Ligustri Ramulus et Folium (Luoshiteng, 络石藤), regardless of the quantity, finely chop it, soak it in wine overnight, strain it, dry it in the sun, and it is ready for use.
Lei Gong said: For Polygalae Radix (Yuanzhi, 远志), the heart must be removed first. If the heart is not removed, ingestion will cause chest stuffiness. After removing the heart, soak it in decoction of prepared Glycyrrhizae Radix et Rhizoma (Gancao, 甘草) overnight, strain it, dry it in the sun, and use it.
Lei Gong said: For Dendrobii Caulis (Shihu, 石斛), after harvesting, dry it in the shade. When preparing for use, cut off the roots, soil, and head with a copper knife, chop it, soak it in Glycyrrhizae Radix et Rhizoma (Gancao, 甘草) decoction overnight, strain it the next morning, dry it in the sun, and use it. Do not take it on an empty stomach, as it may lead to urinary incontinence.
Lei Gong said: For Gnaphalii Herba (Tianmingjing, 天名精), carefully pick out plants with double leaves, as they are harmful if ingested. Remove the head and soil, soak in melon juice overnight, strain it the next morning, dry it in the sun, and use it.
Lei Gong said: For Epimedii Folium (Yinyanghuo, 淫羊藿), first remove the head and soil, soak in wine overnight, strain it, and dry it in the sun. Then steam it with butter from Si hour to You hour (approx. 9 AM to 7 PM), and finally slowly bake it dry. Dendrobii Caulis (Shihu, 石斛) locks fluids and astringes male vitality. However, processed Epimedii Folium (Yinyanghuo, 淫羊藿) like this, if taken for a full yi (ancient weight unit), will permanently prevent bone pain.
Lei Gong said: For Lycii Fructus (Gouqizi, 枸杞子), soak in Lycii Fructus (Gouqizi, 枸杞子) decoction overnight until slightly soft. Strain it, then soak in wine for one shichen (approx. 2 hours), strain it again, and simmer it together with Chrysanthemi Flos (Juhua, 菊花) until scorched yellow. Remove the Chrysanthemi Flos (Juhua, 菊花), wipe dry with cloth, and use it.
Lei Gong said: For Clematidis Radix et Rhizoma (Weilingxian, 威灵仙), first wipe off the fleshy hairs with cloth, then soak in fermented grain water for two shichen (approx. 4 hours). Strain it and bake it dry over willow wood fire. If taking ten taels of this herb, pork must not be consumed; if taken for three years, pork must never be consumed for life.
Lei Gong said: After harvesting, rub off the hairs on the leaves and stems with coarse cloth. Soak in decoction of prepared Glycyrrhizae Radix et Rhizoma (Gancao, 甘草) for one shichen (approx. 2 hours), take out, slice, dry in the sun, and it is ready for use.
