中文摘要：

中药和中药饮片是基本药物目录的重要组成,是我国基本药物制度中医药特色的集中体现。然而以＂安全、必需、有效、价廉＂著称的基本药物,常常出现供不应求的情况。通常认为中成药多为复方组成,药味多样,相互之间价格可以互补,加之中药价格是波动的,短期上涨也会回落,所以短缺情况不十分严重。但中药价格暴涨暴跌现象普遍,由此造成的厂家停止中成药生产的情况时有发生,短期上涨对投料质量的影响也不容忽视。探讨了通过全国中药资源普查建立中药基本药物供应预警方法的必要性和可行性,并且以复方丹参片为实例进行了说明和演示。

英文摘要：

Chinese materia medica（CMM） and pieces of Chinese medicine are important composition of National Essential Drugs List, which also embodys the characteristics of traditional Chinese medicine（TCM）. National Essential Drugs List is well known for its ＂safe, necessary, effective, inexpensive＂, but some chemicals in the list are often short of supply because of their low cost. Usually, Chinese patent medicine composes of more ingredients in prescription, among which there is a complementary price and the price fluctuation is in the normal range. But in recent years, some CMM prices experience massive run-ups followed by precipitous falls, which results in medicine manufacturers stopping production. The effect of short-term rising on feed quality can not be ignored. This article discusses the necessity and feasibility of early warning methods for the essential Chinese medicine supply based on National Census of CMM Resource Survey, and this method is explained and demonstrated with Compound Danshen Tablets as example.
