中医方剂中的“使药”,由于排在“君、臣、佐、使”组方原则的最后一位,故常被人所忽视;就是在某些方剂学的教科书中,也往往被一笔带过,使学者“囫囵吞枣”,不得其要。笔者认为,使药是一个完整方剂的有机组成部分,有其特殊的意义.现将其涵义、作用及其药理研究简述于下,并作初步的探讨. The “medicine” in Chinese medicine prescriptions is often overlooked because it is ranked last in the principle of “junial, ministerial, courteous, and ambassadorial”.

Now its meaning, role and pharmacological research are briefly described below, and preliminary discussions are made.
