Cornsilk, 1 lb. Latin: Zea Mays Cornsilk refers to the stigmas from the female flowers of maize., fine soft threads 10-20cm long. When fresh, they are like silk threads of a light green or yellow-brown colour; when dry, they resemble fine, dark, crinkled hairs. It is used for renal problems in children and as a urinary demulcent combined with other appropriate herbs in the treatment of cystitis, urethritis and prostatitis. The diuretic action is in part due to the high concentration of potassium. Zea was used in the past in the treatment of gonorrhoea. French herbalists use it to thin the bile and promote bile flow, and Chinese research confirms this action. It is also believed to lower blood pressure.
