For chronic nephritis, it also has diuretic, detumescence and certain antihypertensive effects. However, it has no diuretic and detumescence effect on ascites caused by liver disease and edema caused by heart failure. Therefore, it is speculated that the function of imperata rhizome is mainly to relieve glomerular vasospasm, thereby increasing renal blood flow and renal filtration rate and producing diuretic effect; At the same time, renal ischemia improved, renin production decreased and blood pressure returned to normal. Therefore, it has good curative effect on acute nephritis, poor curative effect on chronic nephritis, and little effect on liver disease and heart edema. No adverse reactions were observed during the medication, except slight dizziness or nausea in some cases.

Most of the main symptoms disappeared within 10 day after treatment, and hepatosplenomegaly disappeared about 20 days.
