Medication for treating chronic nephritis and preparation method

Abstract

A Chinese medicine for treating chronic nephritis is prepared proportionally from Asiatic pennywort herb, astragalus root and Chuan-xiong rhizome through proportional mixing, adding alcohol solution, reflux extracting, collecting the liquid extract, recovering alcohol, adding deionized water, boiling, cooling and laying aside for 10-24 hrs.

Description

technical field

[0001] The invention relates to a medical preparation and a preparation method thereof, in particular to a medicine especially suitable for treating chronic nephritis and a preparation method thereof. Background technique

[0002] Chronic glomerulonephritis (chronic nephritis for short) is a group of immune diseases that originate in the glomeruli and are composed of various causes and pathological types. The clinical features are insidious onset, lengthy course of disease, varying degrees of proteinuria, hematuria, and casturia in routine urine tests, and most patients are accompanied by varying degrees of edema, hypertension, and renal dysfunction. The disease is often slowly progressing, difficult to treat, and poor prognosis. When the disease gradually develops to the late stage of chronic nephritis, due to the continuous damage of nephrons, there are fewer and fewer surviving nephrons, fibrous tissue hyperplasia, and renal atrophy, eventually leading to ...
