Abstract

A rhodiola powder injection for treating the cardiovascular and cerebrovascular disease such as coronary heart disease, ischemic apoplexy, etc is prepared from rhodiola through extracting, purifying, adding additive, mixing and freeze drying. Its advantages are high curative effect and stability, and long active period.

Description

Technical field [0001] The invention relates to a large-plant rhodiola powder injection, and at the same time, the invention also relates to a preparation method of the large-plant rhodiola powder injection. Background technique [0002] Rhodiola large, also known as Rhodiola narrow leaves, is the dry root and rhizome of Rhodiola kirilowii (Regel.) Maxim. One part of the Pharmacopoeia of the People's Republic of China in 1977 and the Standard of Tibetan Medicine have the effects of promoting blood circulation and stopping bleeding, removing blood stasis and reducing swelling. Folks are used to treat bruises, hematemesis, hemoptysis, and menorrhagia. Pharmacological studies in recent years have shown that Rhodiola grandis has anti-thromboxane formation, anti-myocardial ischemia, anti-virus, anti-radiation, anti-fatigue, anti-aging, improves the aerobic metabolism of hypoxic animals, and enhances the resistance to hypoxic environments. Tolerance and other pharmacological eff...
