“组方原则”是研究方剂组成、配伍的道理。由于疾病症有主次,病有兼夹,或证有转变,为了适应复杂的病情,充分发挥药物的医疗效用,运用复方就必须研究“组方原则”。组方原则古称“君、臣、佐、使”,现称“主、辅、佐、使”,亦有称“主、辅、制、调”者。 “Party principle” is the principle of research prescription composition and compatibility. Since diseases have major or minor illnesses, diseases have clips, or evidence changes, in order to adapt to the complex conditions and give full play to the medical efficacy of drugs, the use of compound prescriptions must be studied on the principle of “group prescription”. The principle of the group’s party has been called “jun, chen, zuo, shi”. It is now called “master, auxiliary, assistant, ambassador,” and also called “master, auxiliary, system, tune”.
