生地黄为临床常用药,其个体大小不等。干品质地坚硬,切制工艺较难掌握,生地黄整个入煎剂难以充分发挥疗效,故基层用药单位每则望(生)地兴叹。近几年来,我们利用夏秋季节气温高(25℃以上)、湿度大(相对湿度80％左右)、生地黄由硬变软时集中切制。这样既能减轻劳动强度,提高工作效率,又可避免因用水浸泡润闷而造成的药效损失。此法推广至本县部分乡镇医院,应用效果较好。具体作法:初夏购足本单位一年所需生地量,抢水洗净,晾晒至干。待夏至后,生地黄个体软化无硬心时,切成三至四毫米薄片,略晒(注意防雨)即可入库收藏,以供配方、制剂使用。我们将此法用于红人参、天门冬、熟地黄等个 Rehmannia is commonly used in clinical medicine, and its individual size varies. The dry quality is hard, and the cutting process is difficult to control. The whole decoction of Rehmannia glutinosa is difficult to fully exert its curative effect. In recent years, we have used high temperatures in winter and autumn (above 25°C), high humidity (about 80% relative humidity), and concentrated production of raw yellow when hardened and softened. This will not only reduce labor intensity and increase work efficiency, but also avoid the loss of efficacy caused by water soaking and boring. This law was extended to some township hospitals in this county, with good results. Specific practices: In the summer of the year, purchase the amount of raw land needed for the unit, wash it with water, and dry it to dryness. After the summer solstice, when the Rehmannia glutinosa seeds are softened without a hard heart, they are cut into slices of three to four millimeters and lightly sunk (pay attention to rain protection) to be stored in the storage for use in formulas and preparations. We use this method for red ginseng, asparagus, rehmannia etc.
