[Li Shizhen said] When using Angelica sinensis (Danggui), the rhizome head (Lu tou) must be removed, and it should be soaked in wine for one night before being used in decoctions. The effects of stopping bleeding and breaking blood stasis differ between the head and the tail. To break blood stasis, use the tail; to stop bleeding, use the head.
[Lei Xue said] When processing Cardamom (Doukou), it must be soaked in a mixture of concentrated Indigofera tinctoria juice and fresh juice of Stemona root (Baibu) for one shichen (two hours). After filtering and sun-drying, mix with fresh Rehmannia glutinosa juice, steam from Si hour to Hai hour, then take out and sun-dry for use.
[Meng Shen said] For dietary consumption, remove the husk, take the kernel, and stir-fry lightly to detoxify, so that it is no longer pungent.
[Li Shizhen said] After harvesting, scrape off the soil skin, cut finely, and steam equally with Polygonatum sibiricum slices for one shichen. Sun-dry and discard the Polygonatum sibiricum.
[Li Shizhen said] Nowadays, people harvest the roots, wash and scrape them into inch-length pieces, mix with ferruginous ore powder (Duanshi), sun-dry and store to prevent insect damage and to whiten the color. For medicinal use, it is lightly roasted.
[Lei Xue said] After harvesting, scrape off the skin and soil from the head with a bamboo knife, cut finely, mix with honey water, and steam from Si hour to Wei hour. Sun-dry for use.
[Li Shizhen said] Nowadays, it is mostly used raw. Only when avoiding cold in the middle jiao is it stir-fried with wine; when used in gynecological blood-regulating formulas, it is stir-fried with vinegar.
[Lei Xue said] After harvesting the root and drying it in the sun, split it with a copper knife, remove the woody core, cut into pieces the size of soybeans, mix with clear wine, steam from Si hour to Wei hour, sun-dry, and use.
[Li Shizhen said] When used in Qi-regulating formulas, it is used raw without heat treatment. If the intention is to consolidate the large intestine, it should be baked in flour until cooked through.
[Lei Xue said] Do not use the root of Anemone raddeana (Yadie caogen) as it resembles the true herb but has different taste and efficacy. Scrape off the yellow-red skin from the harvested root, cut finely, dry in the shade in a triple-layered silk bag. Before use, soak in honey overnight, filter, and use.
[Li Shizhen said] Galangal (Gaoliangjiang) and Red Cardamom (Hongdoukou) are both suitable for stir-frying before use. Some are stir-fried with ginger, Evodia rutaecarpa (Wuzhuyu), and earth from the east wall (Dongbitu) before use.
[Lei Xue said] Remove the stem, take the inner seed and peel. Stir-fry slowly with Evodia rutaecarpa (Wuzhuyu) in a pan. When the Evodia turns slightly yellow-black, remove the Evodia, and pound the Alpinia oxyphylla peel and seeds for use.
[Li Shizhen said] Nowadays, people wrap it in flour and bake it over fire until cooked, then remove the peel for use.
