The present invention relates to a peripheral circulation improving agent containing crude drugs, and more particularly to a peripheral circulation improving agent containing extracts of one or more crude drugs. Blood vessels in a normal state in the living body maintain a certain tension, that is, vascular smooth muscle maintains a certain tension, thereby forming peripheral resistance.
Along with cardiac output, it is the most important factor determining blood pressure. Therefore, it is necessary for drugs that act on peripheral blood vessels to be able to constantly maintain normal blood pressure and blood flow, which are indicators of the physiological functions of blood vessels, in response to abnormal fluctuations in blood pressure and blood flow. Drugs used to treat peripheral circulatory insufficiency are broadly divided into vasodilators and vasoconstrictors. Examples of peripheral circulatory insufficiency to which vasodilators are applied include (1) arterial thrombosis; (2) Arteriosclerosis obliterans, thrombosis obliterans (B. ¨urger's disease), in which blood flow is reduced due to organic lesions in the arteries; (3) sympathetic nervous system lesions, as in Raynaud's disease, acropurpura, and erythema reticular depressus; Typical examples include: (4) thrombophlebitis, lower extremity venous retention, and (5) blood circulation disorders due to aging. Drugs that have peripheral vasodilatory effects are expected to be effective against a wide variety of peripheral circulatory insufficiency, but they may also have side effects, so it is desired to provide highly safe drugs. The present inventors have been conducting various studies on the pharmacological effects of various crude drug extracts, since crude drugs have been widely used since ancient times, are highly safe, have mild effects, and are easy to control dosage. The present inventors have discovered that certain crude drug extracts and crude drug mixed extracts exhibit a much more pronounced peripheral vasodilatory effect than other crude drug extracts, leading to the completion of the present invention. That is, an object of the present invention is to provide a peripheral circulation improving agent containing crude drugs containing as an active ingredient an extract of one or more crude drugs selected from the group consisting of Astragalus, Astragalus, Enseng, and Safflower. It is something to do. Although the crude drug extract blended in the present invention may be extracted from one type of crude drug, it is preferable to blend extracts of two or more types of crude drugs because it exhibits a higher peripheral vasodilatory effect. Although the mechanism of this action is not clear, it is thought that a synergistic effect is exerted. Such a synergistic effect can also be obtained when other herbal medicines are used in combination with other herbal medicines, which have inferior peripheral vasodilatory effects than the four herbal medicine extracts mentioned above, namely, herbal medicine extracts obtained from genshen, ginseng, dangki, and peony. It was found that it was effective. Therefore, the present invention provides an extract of one or more herbal medicines selected from the group consisting of Astragalus, Astragalus, Enseng, and Safflower; Another object of the present invention is to provide a peripheral circulation improving agent containing crude drugs containing extracts of one or more crude drugs. Extracts containing active ingredients from crude drugs are obtained by extracting the active fraction from crude drugs with various solvents such as water and alcohols.
If desired, this extract may be further purified by conventional methods such as dialysis and various types of chromatography.
When combining two or more crude drug extracts, each crude drug may be extracted separately and then mixed, but a mixture of two or more crude drugs may be subjected to the extraction process at the same time, resulting in a crude drug mixed extraction. It is not only industrially advantageous to obtain a product, but also medicinally advantageous. Although the mixing ratio can be selected as appropriate, a mixture of equal amounts is usually preferred. Next, test results regarding the peripheral vasodilatory effects of various herbal medicine extracts and herbal medicine mixed extracts are shown. Preparation of sample solution Dried shredded powder of various herbal medicines listed in Table 1 below.
100 g was heated under reflux for 3 hours with 300 ml of 50% aqueous ethanol to extract the active ingredients, and the extract was filtered and concentrated to dryness to obtain a crude drug extract. In addition, equal amounts of dried shredded powder of a mixture of 2 to 8 types of crude drugs are mixed, water is added in an amount of 3 to 30 times the weight of the total crude drug, and the mixture is heated and extracted.
After filtration, the mixture is concentrated to dryness to obtain a crude drug mixed extract. Dissolve each crude drug extract in physiological saline and use it as a sample solution. Measurement of peripheral vasodilatory effect Male rabbits weighing 2.8-3.5Kg and weighing 2.5-3.5Kg
Male and female cats of Kg were anesthetized with pentoparbital-sodium, fixed in the dorsal position, and tested under artificial respiration with a tracheal cannula attached. A prologue for an electromagnetic blood flow meter (manufactured by Nalco) was installed in the femoral artery.
The above sample solution was directly administered into the femoral artery via a cannula attached to a side branch of the femoral artery to examine its effect on blood flow. The results are shown in Table 1.
