Lei Gong said: When using (Bixianzi/Ricinus Communis Seed), do not use those that are black and short or red and slender, as they grow on wild grapevines, have pointed ends at both poles, are toxic, and are not used in prescriptions. The true Ricinus Communis Seed resembles Croton Seed (Badou) in shape and has yellow and black spots on its segments.
When preparing for use, first boil the whole seed with salt water for half a day, remove the husk, extract the kernel, grind it, and then use it.

For the seeds, do not remove the membranous testa completely; use them together with the skin.
Lei Gong said: After harvesting, wash thoroughly with clear water, scrape off the outer epidermis, cut into bean-sized pieces on a locust wood board with a copper knife. Then, place them in a raw linen bag, soak overnight in black soybean water, take out, mix with wine to moisten, and steam from Si hour (09:00-11:00) to Hai hour (21:00-23:00). Take out and sun-dry.

Lei Gong said: When using (Gusubi/Drynaria Rhizome or similar hairy rhizome), after harvesting, first use a copper knife to scrape off all the yellow-red hairs, then finely chop. Mix with honey to moisten, steam in a willow steamer for one day, take out, and sun-dry.
