Abstract

The invention relates to a drug preparation technology, and aims to provide an application method of radix paeoniae alba and herba dendrobii officinalis to preparation of an antihypertensive drug. Theapplication method comprises the following steps: grinding radix paeoniae alba into powder, performing alcohol extraction on the radix paeoniae alba powder, extracting residual water left after the alcohol extraction, and combining concentrated extracting solutions; grinding the caulis dendrobii officinalis into powder, adding the caulis dendrobii officinalis powder into the combined extracting solution, and adding accessories to obtain the antihypertensive drug. A combination of an extract prepared by alcohol extraction and water extraction of the radix paeoniae alba and the caulis dendrobiiofficinalis powder has an outstanding curative effect on hypertension, and has an antihypertensive effect which can exceed a western medicine of irbesartan. Compared with conventional water extraction, the alcohol-water extraction method for the radix paeoniae alba has the advantages that component loss is reduced, the effectiveness is improved, complete utilization of oral radix paeoniae alba byhuman body is facilitated, and the curative effect is improved. Compared with most western antihypertensive drugs, the antihypertensive drug has a selective regulating effect on people with high blood pressure without influencing normal blood pressure: the antihypertensive drug can lower high blood pressure, but do not lower normal blood pressure or lower the high blood pressure below normal level.
