Corn silk has diuretic effect on human and rabbits, which can increase chloride ion excretion, but its effect is weak. The methanol-insoluble part of its water extract (A) has the strongest diuretic effect after dialysis, and it has obvious effect no matter oral, subcutaneous or intravenous administration. The diuretic effect is mainly outside the kidney, and the effect on the kidney is very weak.

② Influence on circulatory system

Intravenous injection of decoction in anesthetized dogs has obvious antihypertensive effect, but taking medicine for 3 weeks every day has no antihypertensive effect on chronic carotid bridge dogs. At low concentrations, nails can dilate peripheral blood vessels.

③ Hypoglycemic effect: The corn stigma fermentation preparation has a very significant hypoglycemic effect on rabbits.

④ cholagogic and hemostatic effects: Corn Stigma preparation can promote bile excretion, reduce its viscosity and reduce its bile pigment content, so it can be used as a cholagogic drug for patients with chronic cholecystitis and cholangitis without complications. It can also accelerate the process of blood coagulation, increase the content of prothrombin in blood and increase the number of platelets, so it can be used as a hemostatic and diuretic for bladder and urinary calculi.
