Corn Silk: A Natural Remedy for Urinary Tract Infections (UTIs)

Green corn field growing upFresh corn-on-the-cob may be a favorite grilling vegetable but don’t toss its outer shell too quickly. Indigenous Americans and communities throughout Latin America and Central Europe have long used corn silk as a remedy for urinary tract infections, kidney and bladder infections, bed-wetting, as well as prostate problems. A 2012 article published in the Journal of Intercultural Ethnopharmocology reports scientific evidence for corn silk’s healing properties as well.

While many people in the US turn to cranberry juice or cranberry supplements when they have signs of a UTI, cranberry juice most often contains processed sugar and additives and can sometimes irritate the bladder or aggravate preexisting acid reflux. Like cranberries, corn silk is a diuretic but it also contains unique anti-inflammatory compounds as well as Vitamin K and potassium, which support blood circulation. Note that corn silk’s high amounts of potassium can interact with some blood pressure medication so you should check with your doctor if you have questions about this.

The tea that is made from corn silk is very mild: It tastes like sweet corn water. It generally resolves mild UTIs within a day or two. According to many herbalists, small amounts of corn silk tea are safe to drink during pregnancy, while breastfeeding, and for children but, as with any herbal remedy, consult your physician if you have concerns.

It is important to note that most corn in the US is sprayed with chemicals and genetically modified organisms (GMOs). Many studies have shown that these toxins can negatively affect human cells. Use non-GMO corn or organic corn if possible.
