The thread growing from fresh corn on the cob is often discarded and never thought of again. But that thread, known as corn silk, can be of use. Research has shown that corn silk has many nutrients and other health benefits. The silk is edible, with simple nutrients, and can provide a bountiful amount of vitamins c, k, potassium, and more.

Corn silk is wispy and gold, and most people usually just toss the tiny, delicate strands. But, they can be brewed into corn silk tea. It is believed that the Aztecs and Mayans originally used this tea. For over 6000 years, evidence shows this tea being used for medicinal purposes.

High blood pressure treatment: The properties of corn silk may make it a good treatment for high blood pressure. It helps flush excess fluids from the body, and it acts as a diuretic. A diuretic is a supplement or medicine that helps to rid the body of water and salt/sodium. Sodium helps to get water out of the body and decreases fluid in the arteries and veins, thus reducing blood pressure. Prescription diuretics treat high blood pressure and other heart conditions. Studies show corn silk extract contains chemicals that hamper the work of the angiotensin- converting enzyme (ACE), which is known to increase blood pressure. People who were given corn silk supplementation ultimately had decreases in blood pressure, depending on the corn silk concentration.
