Abstract

The invention provides a medicinal composition containing an atractylodes rhizome extractive, which can be composed of the atractylodes rhizome extractive, timosaponin B-II and berberine, can be also composed of the atractylodes rhizome extractive, a rhizoma anemarrhenae extractive and a phellodendron bark extractive, or can be obtained by directly extracting from atractylodes rhizome, rhizoma anemarrhenae and phellodendron bark. The composition of the invention has obvious effect of reducing blood sugar, high content of effective ingredients, easy quality control, easy industrialization of preparation process; and the composition can be applied to the medicine for preventing and treating diabetes.

Description

technical field [0001] The present invention relates to a composition composed of various plant extracts, in particular to a pharmaceutical composition containing Atractylodes atractylodis extract, which is used for the prevention and treatment of diabetes. Background technique [0002] Diabetes Mellitus (DM) is a series of clinical syndromes caused by absolute or relative insufficiency of insulin in the body. Among diabetic patients, type II diabetes (Diabetes type II, non-Insulin Dependent Diabetes Mellitus, NIDDM) patients account for the vast majority. Due to the disorder of glucose metabolism, some complications will also be caused during the development of the disease, such as: hypoglycemia (Hypoglycemia), ketoacidosis (Ketoacidosis), nonketotic hyperosmolar coma (Nonketotic Hyperosmolar Coma), cardiac Vascular disease, chronic renal failure, retinopathy, neuropathy and microvascular disease, etc. There are three main types of drugs commonly used in the treatment of ...
