　　The efficacy and function of corn silk

　　1． diuresis

　　Corn silk decoction 5g/kg or 10g/kg was administered intragastrically. Bears significantly increased the urine output of awake rabbits in the first and second hours after administration. The high-dose group had a strong effect, which was weaker but longer-lasting than furosemide. The water extract was injected intravenously at 1.5 mg/kg. The first diuretic effect appeared in rabbits after 4 minutes, and a strong second diuretic effect appeared after 13 to 15 minutes. After neutralizing with sodium hydroxide and then using bladder membrane dialysis, the diuretic effect remains unchanged, indicating that the diuretic component is not the inorganic salt contained. This product has a diuretic effect when taken orally or injected subcutaneously. After administration, first the concentration of chloride in the blood increases, and then the urine output and chloride content in the urine increase. The diuretic mechanism is mainly extrarenal and is related to coffee There is a synergistic effect due to combination. 8-10g of corn silk is made into a decoction and taken orally. It has a mild diuretic effect on normal people, but is weaker than Polyporus polyporus and caffeine. There are also reports clinical A controlled study on amenorrhea and amenorrhea showed that there was no significant difference in the 12h and 24h urine output and urinary sodium excretion of this product compared with the control group.

　　2. Antihypertensive effect

　　Corn silk water infusion, ethanol water infusion, ethanol infusion and decoction have antihypertensive effects when injected intravenously into anesthetized dogs, cats and rabbits. The decoction was given intravenously (0.05-0.2g/kg) or intraocularly (2g/kg) to anesthetized dogs, which reduced blood pressure by 30%-73% and 53% respectively, which took 2-5h and 5-10h to recover. When corn silk boiled water dialysate (1.37-22 mg/kg) is injected intravenously into normal anesthetized dogs, it produces a dose-dependent antihypertensive effect, which takes effect in 15 minutes and lasts for 80 minutes, accompanied by obvious heart rate reduce. However, there are also reports that the same dose mentioned above was fed to conscious dogs for 3 weeks, but no antihypertensive effect was seen. ； Intraperitoneal injection of corn silk into hypertensive rats has antihypertensive effect, but has no effect on normal rats. Its antihypertensive mechanism is mainly central, and some believe it is mainly the result of dilation of peripheral small blood vessels. Corn silk counteracts the pressor effect of epinephrine. Small doses of corn silk have no effect on the heart. In larger doses, the heart rate increases, slows down, and weakens.

　　3. choleretic effect

　　Corn silk can significantly increase bile secretion and promote bile excretion. It can reduce the organic matter and residue in bile, and reduce the viscosity, specific gravity and bilirubin content. Reflexive contraction of the gallbladder occurs 15-30 minutes after oral administration of corn silk preparations, and bile selection increases. This effect is slower than that of magnesium salts, but it is more lasting and is not accompanied by increased intestinal motility and loose stools.

　　4. Hypoglycemic effect

　　The fermentation preparation of corn silk has obvious hypoglycemic effect on rabbits； Water decoction 7, 5g/kg, 15g/kg, 30g/kg orally administered for 7 consecutive days has a significant therapeutic effect on diabetes in mice caused by alloxan. Grape Hyperglycemia in mice caused by sugar and epinephrine also has obvious hypoglycemic effects. However, there was an obvious dose-effect relationship, but it had no significant effect on the blood pressure of normal mice. It is suggested that corn silk may have the effect of dual muscle hypoglycemic drugs.

　　5. Other functions

　　Corn silk water 15g/kg, 30g/kg, intragastric administration for 7 days can significantly reduce the serum cholesterol content of hypercholesterolemia mice. Corn silk contains vitamin K, which has a therapeutic effect on coagulation disorders caused by vitamin K deficiency.

　　6． toxicity

　　Various oral preparations of corn silk are almost non-toxic, and the water decoction is administered through the stomach. The maximum tolerated dose of mice is >171g/kg. The lethal dose of the methanol-insoluble part (diuretic component) extracted from water in rabbits is 250mg/kg, and the optimal diuretic dose is 1.5mg/kg for intravenous injection and 6mg/kg for oral administration. The above diuretic doses have little effect on the heart, respiration, peripheral blood vessels and intestinal muscles.

　　Corn silk is suitable for everyone

　　It can be consumed by the general population.
