分析了中药汤剂配伍时各单味药的剂量对疗效和毒副作用的影响。提出了由于选择功效的不同,在不同的处方中,虽为同一药物但要选用不同的剂量。增强功效或降低毒副作用的配伍,只有在一定的剂量比例和浓度下才能保证君药与配伍药物、配伍药物之间存在着这种效应。随着配伍药味的变化,方中其它药物的剂量应随之调整。
The effects of the doses of the individual herbs on the efficacy and toxic and side effects of the Chinese herbal decoction were analyzed. It is proposed that different doses may be used in different prescriptions for the same drug, due to differences in selection efficacy. The compatibility of enhancing the efficacy or reducing toxic and side effects can only be guaranteed under the certain dose ratio and concentration. With the changes in the medicinal flavor, the dose of other drugs in the prescription should be adjusted accordingly.
