Description

Polygonatum sibiricum and grapefruit tea and preparation method thereof

Technical Field

The invention belongs to the technical field of medical health-care products, relates to a polygonatum sibiricum and grapefruit tea and further relates to a preparation method of the polygonatum sibiricum and grapefruit tea.

Background

With the acceleration of the pace of life and the increase of working pressure in modern society, the change of diet rules leads to the gradual increase and the youthful occurrence of cardiovascular diseases, especially the incidence rate of myocardial infarction. In the health food management method published by the Ministry of health in 1996, some Chinese medicinal herbs with dual purposes of medicine and food are allowed to be prepared into health products. Therefore, the use of traditional Chinese medicines in China to prevent cardiovascular diseases and improve the state of sub-health people gradually becomes a research hotspot.

The traditional Chinese medicine classifies the myocardial infarction into the categories of 'obstruction of qi in the chest' and 'palpitation', and the pathogenesis of the myocardial infarction is mainly 'obstruction of qi deficiency, blood stasis and collaterals', which is the syndrome of principal deficiency and secondary excess. Qi deficiency and yin deficiency are the pathological basis of the disease, blood stasis is the principal and the pathogenesis of principal deficiency and secondary excess runs through the whole course of myocardial infarction. Heart qi is the source of power for promoting blood circulation, and abundant heart qi can ensure normal beating rhythm of heart and blood circulation. Qi deficiency can not reach blood vessels and can cause blood stasis. Because qi deficiency causes the body to promote and transform qi, blood stasis will inevitably affect the function of heart governing blood vessels, and further induce myocardial infarction.

Tea therapy is a common conditioning mode in people's life, and the method is simple and convenient, can preserve health and treat diseases, and is deeply loved by people. In recent years, the nutritional effect and the pharmacological effect of the tea are continuously discovered by people, and the health-care function and the disease prevention and treatment effect of the tea are ensured.
