杜仲是一味名贵中药材,该药资源有限,传统炮制损耗过大。为了提高杜仲的利用率,笔者在长期的实践中逐渐摸索出“砂烫法”炮制杜仲的新方法,该法具有工艺简单,易于掌握,损耗率低的特点。现介绍如下: 方法:将原药按薄厚分开,切成约2cm×2cm的方块(片),分别存放,选取纯净或淘洗净的细河砂,用16目铁筛筛去粗块粒,备用。炮制时先将细砂投入铁锅内(砂为药重量的5倍以上),用武火炒至细砂滑利,易于翻动时,再把切好的杜仲按薄厚分别埋入砂内,约2分钟后降低火力,依次均匀的翻动,烫至色变焦褐,丝断后,用铁筛迅速将药筛出,放容器内,用3％的食盐水喷淋或拌入药内,盐水吸渗均
Eucommia is a rare Chinese herbal medicine. The medicine is limited in resources, and the traditional processing is excessive. In order to improve the utilization rate of Eucommia, the author has gradually explored a new method of processing the Eucommia ulmoides with the “sand-burning method” in the long-term practice. The method has the characteristics of simple process, easy to master, and low loss rate. Now introduced as follows: Method: The original drug is divided by thin thickness, cut into about 2cm × 2cm squares (pieces), respectively, storage, select pure or panning Xihe sand, with 16 mesh sieve to remove coarse chunks, spare. When processing, put the fine sand into the iron pan first (sand is more than 5 times of the weight of the medicine), use the fire to fry the fine sand and slide profit, when it is easy to turn, then bury the cut Eucommia into the sand according to the thin thickness, about 2 After a few minutes, reduce the firepower, turn it evenly and turn it in order, and then scald it until the color is brown. After the wire is broken, quickly sieve the medicine out with a metal sieve, put it in the container, spray it with 3% salt water, or mix it into the medicine.
