单味药通过配伍组合,既能增强或改变它原有的功用,又能调和偏胜,制其毒性,解除或缓和对人体不利的影响。因此,药物配伍组成方剂后,就能产生综合效力。现将方剂的组成基本原则及变化规律阐述如下。一、组成基本原则组成一个方剂,具有严格的原则。首先要在辨证立法的基础上,选择适当的药物,规定必须的剂量,按着一定的组方原则组合而成。这种组方原则早在《内经》已经提出,如《素问·至真要大论》说:“主病之谓君,佐君之谓臣,应臣之谓使”。后世医家又从理论上清楚而准确地加以论述,使之方剂的组成基本原则日臻完善。下面 The single herb can enhance or change its original function, and can also reconcile the partial victory to make its toxicity, relieve or mitigate adverse effects on the human body. Therefore, after the drugs are combined to form a prescription, comprehensive efficacy can be produced. The basic principles and changes in the composition of prescriptions are described below.
