1, diuretic effect: corn stigma has diuretic effect on human or rabbit, and chloride can be added for excretion, but the effect is weak. The methanol-insoluble part of its water extract has the strongest diuretic effect, and it has obvious effect whether taken orally, subcutaneously or intravenously. The diuretic effect is mainly outside the kidney, and the effect on the kidney is very weak.

2. Effect on circulatory collapse: Intravenous injection of decoction in anesthetized dogs has obvious hypotensive effect, but it has no hypotensive effect on chronic carotid bridge dogs after taking medicine for 3 weeks every day. At low concentrations, nails can dilate peripheral blood vessels.

3. Hypoglycemic effect: Corn silk fermentation preparation has obvious hypoglycemic effect on rabbits.

4, cholagogic hemostasis: Corn Stigma preparation can promote bile excretion, reduce its viscosity and increase 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 slow down 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.

Because corn is wrapped in corn bags during its growth, it needs corn stigma to absorb nutrients, so corn stigma contains many vitamins and other nutrients, which can not only cool blood and reduce fever, but also dispel damp heat in the body, induce diuresis and reduce swelling, and make tea into a good weight-losing drink.

Corn silk is sweet and flat. Other nutrients can enhance human metabolism, regulate nervous system function, make skin soft and smooth, and inhibit and delay the generation of wrinkles. In traditional Chinese medicine, corn stigma is also called Gracilaria lemaneiformis, which is sweet and flat, and has a wide range of preventive and health care uses.
