The invention relates to the field of
medicine preparation technologies, and aims to provide a method for preparing a
medicine for treating hypertension from peony root, herba dendrobii officmalis andirbesartan. The method comprises the steps that after the peony root is subjected to levigation,
alcohol extraction is conducted, residues after
alcohol extraction are subjected to
water extraction treatment, and concentrated extraction solutions are combined; the herba dendrobii officmalis is subjected to levigation, herba dendrobii officmalis
powder and
irbesartan powder are added into the combined extraction solution for even mixing; an accessory is added to prepare the
medicine for treating hypertension. In the method, the
curative effect of an
alcohol and
water extraction method extractof the peony root and the herba dendrobii officmalis
powder on treating hypertension is outstanding, compared with conventional
water extraction, the alcohol and water extraction method of the peony root has the advantages that component loss is reduced, thus the effectiveness is improved, and full use of the peony root can be promoted; through compatibility of the herba dendrobii officmalis withthe peony root, not only can the
efficacy of decreasing the
blood pressure be achieved, but also the good mid-term and long-term
stable blood pressure can be obtained, and the physique with equilibrium between
yin and yang is adjusted and recovered; by means of the
traditional Chinese medicine and
western medicine combined composition, under the condition of a small
western medicine dosage, the
curative effect close to that of the conventional dosage of a western hypotensive medicine can be achieved, and thus the application prospects are greatly expanded.
