Traditional uses

Corn has fed the Americas for thousands of years, first domesticated from wild teosinte grass by Indigenous farmers in what is now Mexico and cultivated into the plump, sweet ears we know today. Beyond the table, the fine golden threads called corn silk, gathered from the top of each ear, were steeped into teas by Native American, Chinese, and early American folk healers who traditionally used them to soothe the urinary tract and encourage healthy fluid balance. Every part of the plant found a use in traditional households, from cornmeal for bread to the husks for weaving and wrapping food.

Did you know?

A single ear of corn has, on average, the same number of silk strands as it does kernels, since each strand is actually the style of one individual flower waiting to be pollinated.

Safety

Corn silk is generally safe for occasional traditional use, though it may affect blood sugar and potassium levels and can interact with diuretics or blood thinners. Corn itself is a common food allergen for some people.
