Lei Gong said: When using Vitex fruit (Man Jing Shi), remove the stem and peel off a layer of white membrane beneath the seed. Soak in wine for one shichen (12 hours), then steam from Si hour to Wei hour. Remove, dry in the sun, and use.
Lei Gong said: When using this herb, remove the rough outer skin and wipe off the red fleshy hairs on the surface. After cleaning, soak in banana juice overnight. Drain, boil in rice vinegar water from Si hour to Wei hour. Remove, bake until dry, and use.
If treating eye diseases, remove the skin all at once and use only the inner flesh.
Lei Gong said: Regarding collection, it refers to naturally growing single-branch trees on the tree.
For processing, after harvesting, finely chop the roots, branches, and stems with a copper knife. Dry in the shade and use as needed.
Do not expose to fire.
Lei Gong said: When using, first scrape off the coarse skin. Mix with butter (Su) and honey (Mi), roast until fully absorbed. Once roasted and dried, finely chop and use.
For every jin (approx. 500g) processed, use 2 liang of butter and 3 liang of honey. Mix these two ingredients together for use.
Lei Gong said: When using, first soak in hot water, remove the skin and tips, and split into two halves. Boil with Mang Xiao (Mirabilite) and Mutong Cao (Akebia Caulis) and Reng Ren (Prunus Persica Seed/Prunus Armeniaca Kernel context implies specific kernel here, likely Prunus armeniaca or similar, but text says Reng Ren) together for one shichen. Strain, discard the medicinal residues, take the Reng Ren, grind into a paste, and add to prescriptions as required.
For every 4 liang processed, use 1 liang of Mang Xiao and 7 liang of Mutong Cao.
Lei Gong said: There are male and female varieties. The male grains are small; the female grains are large, resembling jujube pits. Prescriptions mostly use the female variety due to its stronger efficacy; the male variety is used for making pastes and syrups.
If using the male variety, the tip/spine must be removed, as it is where the seed develops and can cause carbuncles on the back.
Lei Gong said: For Agarwood (Chen Xiang), select pieces that are not dry/withered. The best quality is hard like horn, heavy, and sinks in water; those that sink halfway are of secondary quality.
When used in pills and powders, add it after other herbs have been prepared, mix well, and use.
Lei Gong said: The seeds inside the Malus asiatica (Lin Qin) are called Jin Ying Zi; they share the same name. Medical formulas also utilize Lin Qin seeds.
Lei Gong said: The hair to be used must come from a male under the age of twenty, free from disease, with a ruddy complexion, cut from the vertex (Baihui area).
When used in pills, powders, or ointments, first soak in Sophora root (Ku Shen) water overnight. Drain, place in a bottle, calcine over fire until red-hot. Allow to cool, grind, and use.
