Lei Gong said: When all the fruits of Melia azedarach (Chinaberry) are collected, dry them in the sun. Mix with wine and soak until moist, then steam. Wait until the outer skin becomes soft, peel off the skin, take the flesh, and remove the seeds. Do not use the seeds alone; if the seeds are to be used, crush them, boil in rice wash water for one shichen (two hours), and then use.
If using the flesh, do not use the seeds; if using the seeds, do not use the flesh.
Furthermore, the fruit formed after flower fall is called Shizhuyu (Stone Dogwood).
Lei Gong said: Regarding the root of Toona sinensis (Chinese Mahogany), when used, the root is preferred. The part not near the western end of the tree is of superior quality. Do not use the stems or leaves; only use the root.

Lei Gong said: When all the leaves of Dumu Ye (Poisonous Tree Leaf) are used, after collection, finely chop the leaves. Additionally, prepare two herbs: Raw Licorice Root (Gancao) and Water Smartweed (Shuiliao), and finely chop them as well. Place the Dumu Ye in a raw fine silk bag inside a steamer basket (Zeng). Place the Gancao and Shuiliao on top and steam together for one day. Remove the Gancao and Shuiliao, take out the leaves, dry in the sun, and use.
Do not use leaves that have twisted growth at the tips.
Lei Gong said: When all the Mo Shizi (Ink Stone Seed/Stone) is used, avoid contact with copper and iron, and avoid being startled by fire (high heat). Small grains, fine texture, and those without rice-like spots on the surface are excellent.

Then mix with wine and steam again from Si hour to Wei hour as before, dry in the sun, and use.
