Abstract
Description
technical field
[0001] The invention relates to a composition and its preparation method and application, especially the preparation method and application of a composition capable of lowering blood fat, protecting the liver, reducing weight and reducing homocysteine. Background technique
[0002] Astragalus, also known as Mianqi, its main active ingredient is astragaloside IV, which has the functions of inhibiting metabolic syndrome, delaying cardiomyopathy in myocardial ischemia, and improving heart function. , diuretic, anti-aging, anti-stress, antihypertensive and a wider range of antibacterial effects. It can eliminate experimental nephritis proteinuria, enhance myocardial contractility, and regulate blood sugar levels. Astragalus can not only dilate coronary arteries, improve myocardial blood supply, improve immune function, but also delay the process of cell aging.
[0003] Pueraria lobata is the dried root of the leguminous plant Pueraria mirifica, commonly known a...
