Bladder and Urinary Health

As a powerful diuretic and anti-inflammatory, Corn Silk increases urination, thus preventing the buildup of bacteria in the urethra. It soothes inflammation in the bladder and urinary tract and coats the lining of the urethra.

Corn Silk can help to strengthen the urinary system as a whole and is effectively used to prevent bedwetting (enuresis) in children and incontinence in older people. 

Kidney Health

One study found that Corn Silk can help to prevent the formation of kidney stones and can increase the percentage of urinary stones through the urinary tracts. The study entitled "In-vitro Anti-Urolithiatic Activity of Corn Silk of Zea Mays" proved that it exhibited anti-urolithiatic activity - the dissolving or preventing the formation of calculi in the kidneys, ureters, or bladder. The study concluded that, “The aqueous extracts of Corn Silk of Zea mays has shown significant activity on comparison to the synthetic drug Spironolactone, furosemide and poly-herbal formulation Cystone."3

The researchers found that Corn Silk was playing an important physical role in the treatment of kidney stones by increasing the contraction of smooth muscles, which led to increase the urinary output and increased the percentage the passage of urinary stones through the urinary tracts.

Type 2 Diabetes

The hypoglycaemic mechanisms of Corn Silk have been investigated by many researchers the world over. It has a long history of use in Traditional Chinese Medicine as a herbal medicine to treat diabetes.

A 2009 study, “The effects of Corn Silk on glycaemic metabolism”, concluded: “Corn Silk extract markedly reduced hyperglycemia in alloxan-induced diabetic mice. The action of corn silk extract on glycaemic metabolism is not via increasing glycogen and inhibiting gluconeogenesis but through increasing insulin level as well as recovering the injured β-cells.”4

Other studies have shown that Corn Silk also balances blood lipid levels which can prevent and reduce the complications of diabetes. Corn Silk appears to exert a multi-targeted approach on hypoglycaemia which is not as fast as its pharmaceutical counterpart, however the effects are more stable and much safer.

For the early stages of Type 2 Diabetes the use of Corn Silk can help to get sugar levels under control. In severe cases, Corn Silk can be elected to enhance the effect of pharmaceutical drugs and reduce their side effects.

Lowers Blood Pressure

Corn Silk is rich in bioactive compounds such as flavonoids and terpenoids which are thought to contribute to the anti-hypertensive action of this herb. It also contains high amounts of potassium, a mineral that is well known for its vasodilating properties and ability to relieve tension of the blood vessels – one of the main causes of high blood pressure.

Several recent studies have shown that “aqueous extract” of Corn Silk gave a statistically significant reduction in mean intraocular pressure and blood pressure within 8 hours of administration.


Not recommended if you are taking diuretics, blood pressure medication, diabetes medication, blood thinners or anti-inflammatory drugs.
