【陶弘景说】使用时折断去掉节和根，用水煮十余次沸腾，用竹片撇去上面的泡沫。泡沫会让人心烦意乱，因为根和节能止汗的缘故。
【李时珍说】灯心草难以研磨，用粳米粉浆浸染后，晒干再研成粉末，加入水中澄清，浮在水面上的是灯心草，晒干后使用。
【陈藏器说】干地黄，《神农本草经》中没有说明是生干还是蒸干。医家所用的这两种各有所别，蒸干的具有温补作用，生干的则性味平和宣散。
【苏颂说】制作熟地黄的方法：选取肥大的地黄三二十斤，洗净，另外挑选瘦短的地黄三二十斤捣碎绞取汁液，投入石器中，浸泡过滤使其渗透，在甑上浸润三四次，经常浸泡过滤并转蒸，最后暴晒使汁液耗尽。这样的地黄应当光亮黑如漆，味道甘甜，气息温和。
【佚名曰】凡使用（某药，原文缺失主语，据上下文推测可能指黄精或类似根茎类），需去掉头芦，用黄精的自然汁液浸泡一夜，滤出，切碎，焙干后使用。
【李时珍说】现在只用酒浸泡入药，想要药力下行则生用，滋补身体则焙干用，或者用酒拌蒸过后使用。
【佚名曰】凡使用（某药，原文缺失主语，据上下文“羊须草”推测可能指白前或类似药材），需先去掉须根。有白色如绢练颜色的，号称羊须草，自然不同。去掉头部和泥土，用东流水洗净，用蜂蜜浸泡一夜，到第二天在火上焙干后使用。一两药使用二分蜂蜜。
【陶弘景说】凡使用选取肥大的，汤泽（此处疑为衍文或特定处理描述，结合语境指经过水处理），抽去心，不然会让人心烦。大概一斤药需要减去四五两的心。
【佚名曰】凡采收后便粗略捣碎，加入甘草叶相拌共同蒸制，从巳时到未时（约4-6小时），去掉甘草叶，焙干后使用。
【佚名曰】凡采得（某药，原文缺失主语，据上下文推测可能指款冬花），必须去掉向内包裹的花蕊壳，以及向内结实像栗子壳一样的部分。连同枝叶，用甘草水浸泡一夜，却取款冬叶相拌一夜，晒干后去掉叶子使用。
【佚名曰】凡使用只用蕊壳，不用茎叶。如果同时使用，会导致空腹时气噎，小便失禁。使用时用竹沥浸泡一个时辰（2小时），滤出晒干。
[According to Tao Hongjing] When used, break off and remove the nodes and roots. Boil in water for more than ten boils, and skim off the foam on the surface with a bamboo slice. The foam causes irritability because the roots and nodes have the effect of stopping sweating.
[According to Li Shizhen] Juncus effusus (Jungengcao, 灯心草) is difficult to grind. Dye it with rice starch paste, dry it in the sun, then grind it into powder. Add water to clarify it; the material floating on the surface is Juncus effusus. Dry it in the sun for use.
[According to Chen Cangqi] For dried Rehmanniae Radix (Dihuang, 地黄), *Shennong Bencao Jing* does not specify whether it is naturally dried or steamed-dried. In medical practice, these two forms are distinct: steamed-dried Rehmannia has warming and tonifying properties, while naturally dried Rehmannia is neutral and dispersing.
[According to Su Song] Method for preparing Prepared Rehmanniae Radix (Shudihuang, 熟地黄): Select thirty to twenty jin of plump Rehmannia, wash it thoroughly. Separately take thirty to twenty jin of lean and short Rehmannia, crush and squeeze out the juice. Pour the juice into a stone vessel, soak and filter until fully permeated. Steam over a steamer three or four times, frequently soaking, filtering, and turning the steam process. Finally, expose to the sun until the juice is exhausted. The resulting Rehmannia should be glossy and black as lacquer, with a sweet taste and mild aroma.
[Anonymous] Generally, when using [Herb Name Missing], remove the rhizome head and aerial stem remnants. Soak overnight in the natural juice of Polygonati Rhizoma (Huangjing, 黄精). Strain out, chop, and bake dry for use.
[According to Li Shizhen] Currently, only wine infusion is used for medicinal purposes. To direct the action downward, use it raw; for nourishing and tonifying, use it after baking dry, or after mixing with wine and steaming.
[Anonymous] Generally, when using [Herb Name Missing], first remove the rootlets. Those that are white like silk gauze are called Yangxucao (Sheep Whisker Grass) and are naturally different. Remove the heads and soil, wash clean with running water from the east, soak in honey overnight, and bake dry over fire the next day. Use two fen of honey per one liang of herb.
[According to Tao Hongjing] Generally, select plump specimens, treat with hot water, and extract the heart/core. Otherwise, it causes irritability. Approximately four to five liang must be removed from every one jin.
[Anonymous] Generally, after harvesting, coarsely pound the herb, mix with leaves of Glycyrrhizae Radix et Rhizoma (Gancao, 甘草), and steam together from Si hour to Wei hour (approx. 9 AM to 3 PM). Remove the Gancao leaves, bake dry, and use.
[Anonymous] Generally, upon collection, one must remove the inner wrapping bracts/shells and the solid, chestnut-shell-like structures. Along with branches and leaves, soak in Glycyrrhizae water overnight. Then, mix with leaves of Flos Cynarae (Kuandonghua, 款冬花) for another night. Dry in the sun and remove the leaves before use.
[Anonymous] Generally, use only the floral bracts/shells, not the stems and leaves. If used together, it may cause qi obstruction and urinary incontinence in a fasting state. When using, soak in Bamboo Sap (Zhuli, 竹沥) for one shichen (2 hours), strain, and dry in the sun.
