采收后的中药材，除了骨碎补，鲜芦根等少数种类可供鲜药用外，大多用其干品。俗话说“三分种，七分收”，为防止霉烂变质，严重影响药材质量和疗效，也为了便于分级、包装、贮藏、调运，更主要的是为了进一步加工炮制成饮片，药材采收后，除了极少数药材需要新鲜和保持原样外，大部分药材需进行产地初加工。
After harvesting, most of the Chinese medicinal herbs are dried products, except for a few kinds of fresh medicinal herbs, such as Drynaria cordata and Fresh Reed Root. As the saying goes, "three kinds, seven points of harvest", in order to prevent mildew and deterioration, seriously affect the quality and efficacy of medicinal materials, but also to facilitate classification, packaging, storage, transportation, more importantly, to further process processed into pieces, after the harvest of medicinal materials, in addition to a small number of medicinal materials need fresh and maintain the original sample, most of the medicinal materials need to be processed in the original place.
在初加工时，按药材和用药的需要，进行分级和其他技术处理，有利于药材的进一步加工炮制和充分发挥其药用功效，是中药材优质的重要环节和保证。
In the initial processing, according to the needs of medicinal materials and medicines, grading and other technical treatment are conducive to the further processing and processing of medicinal materials and give full play to their medicinal efficacy. It is an important link and guarantee of the quality of Chinese medicinal materials.
