The silky threads at the top of a corn cob have been used by Indigenous American peoples as a gentle diuretic and urinary demulcent for centuries. Corn silk soothes the urinary tract lining, reduces urgency and frequency, and helps flush mild urinary infections when combined with adequate water intake. It is one of the safest urinary herbs, appropriate for children and the elderly.
