Overview

Corn silk is the long shiny fibers at the top of an ordinary ear of corn (Zea mays). It's often discarded as waste but is also used in medicine.

Corn silk contains proteins, carbohydrates, vitamins, minerals, and fiber. It also contains chemicals that might have antioxidant effects, reduce blood pressure, and alter blood sugar levels.

People use corn silk for chest pain, diabetes, high blood pressure, obesity, and many other conditions, but there is no good scientific evidence to support these uses.
