方剂是在辨证立法的基础上,按照组方原则,配伍适当药物,规定合宜剂量,制成一定剂型的成方。中医方剂的数目繁多,为了便于学习和掌握,历代依据方剂的性质,从不同角度,进行按系统归纳,便形成了各种分类方法。综合方剂的分类法,大致有七方分类、按方剂功能分类、按主治病症分类、按类方分类、按剂型分类、按临床学科分类等,现分述如下。一、七方分类主要是以病情轻重、病位上下、病情缓急、药味奇偶等作为方剂分类的依据,从而把方剂分为大、小、缓、急、奇、偶、复等七类。这种分类方法,最早见于《黄帝内经素问·至真要大论》,到金代成无已在《伤寒明理论》中才明确为“七方”。一般认为: The formula is based on the dialectical legislation, in accordance with the principle of group prescription, compatibility with appropriate drugs, prescription appropriate dose, made into a prescription for a prescription. There are a large number of Chinese herbal medicine prescriptions. In order to facilitate learning and mastering, various classification methods have been formed based on the nature of prescriptions from different angles and systematically summarized from different perspectives. The classification of comprehensive prescriptions can be roughly classified into seven categories, classified by prescriptions, classified according to indications, classified by category, classified by dosage form, and classified by clinical discipline. The classification is as follows. First, the seven-party classification is mainly based on the severity of the disease, the disease position up and down, the condition is urgent, drug taste parity, etc. as the basis for classification, thus the prescription is divided into large, small, slow, urgent, odd, even, complex and other seven categories. This kind of classification method was first seen in The Yellow Emperor’s Neijing Suzheng Zhizheng Great Theory, and Jin Chengcheng Wuyi has been clearly identified as the “Seven-Party” in the “The Theory of Shanghan Ming”.
