Description

Composition with auxiliary blood sugar reducing function and application thereof
Technical Field
The invention relates to a composition with a function of assisting in reducing blood sugar, and also relates to application of the composition in preparing a medicinal preparation or health-care food for reducing blood sugar, belonging to the field of health-care food for assisting in reducing blood sugar.
Background
Diabetes is a group of endocrine metabolic diseases of which the etiology and pathogenesis are not completely clear, the incidence rate of the diabetes is on the trend of increasing year by year, the diabetes is the third major difficult disease after cardiovascular and cerebrovascular diseases and malignant tumors, and no radical treatment therapy exists at present. The focus of traditional Chinese and western medicine is also different in the treatment of diabetes. Western medicine mainly adopts oral hypoglycemic agent or insulin supplementation for treating pancreatic islet insufficiency or absolute or relative insulin insufficiency, and has the advantages of quickly and accurately reducing blood sugar, controlling the blood sugar within an ideal range, and particularly playing a unique role in the acute complications of ketoacidosis, hyperosmolar coma and the like of diabetes. However, the progressive damage and other side effects of the traditional Chinese medicine composition to the vascular nerves do not have effective measures for preventing and delaying the occurrence of the progressive damage and other side effects. The treatment of diabetes in traditional Chinese medicine is based on treatment based on syndrome differentiation, and 2 refracting surfaces of the disease's principal and secondary aspects' are usually grasped from the whole body. Diabetes causes disorder of metabolism of sugar, protein and fat and imbalance of water and electrolyte, so the clinical manifestations are polydipsia, diuresis, emaciation, hypodynamia, etc., the essence of the disease is deficiency syndrome, and the sign is heat syndrome. Therefore, the traditional Chinese medicine usually adopts the therapeutic principles of clearing heat, tonifying qi, nourishing yin, warming yang and the like to achieve the balance of yin and yang of the organism.
Diabetes has become a major stubborn disease in today's society, and due to the large population base in China, the total number of diabetics has become one of the most frequent countries in the world. Therefore, the task of diabetes prevention and treatment is becoming one of the major public health problems in China. The huge group of diabetics makes the market of Chinese health-care food for assisting in reducing blood sugar greatly demanded. Therefore, in order to meet the requirements of the majority of people with high blood sugar, the traditional Chinese medicine theory is combined, a composition with the function of assisting in reducing blood sugar is developed, and the composition can assist the people with high blood sugar or the diabetics in controlling blood sugar so as to improve symptoms caused by blood sugar increase, and has important significance and value.
