Cornsilk is the soft hair between the corncob and the outer sheath. This herb is useful in any kind of urinary irritation or disorder, as it both soothes and tones the urinary tract at the same time. It can be used to treat cystitis, urethritis, prostatitis and oedema.

Although gentle enough to use for kidney problems in children, cornsilk will also often have success with kidney stones when nothing else will work. For infections of the urinary tract, cornsilk is best combined with uva ursi.
