Corn hair is being called a kidney remedy: What science actually says

Yoga and wellness coach Radhesa highlighted the potential benefits of corn silk, also called corn hair, for kidney and urinary health in a video post. According to Radhesa, corn hair is a kidney and liver-friendly diuretic that can help increase urine flow. However, experts caution against overestimating the claims. Dietician and certified diabetes educator Kanikka Malhotra explains that corn silk does indeed have diuretic properties, increasing urine output and potentially reducing urinary tract infection (UTI) risk.

It may also inhibit a pathway associated with blood pressure regulation, offering a mild blood pressure-lowering effect. Furthermore, corn silk has antioxidant and anti-inflammatory properties that could benefit kidney tissue. Nonetheless, these benefits do not equate to treating kidney disease or dissolving existing kidney stones.

Increased urine flow from corn silk helps dilute substances that can contribute to stone formation, making it a preventive measure rather than a cure. While corn silk can be a flavorful way to meet fluid intake goals, it should not replace regular water consumption, especially for individuals prone to kidney stones. For those already experiencing a kidney stone, corn silk water is not a treatment option.

In cases of recurrent UTIs, medical evaluation is necessary as corn silk water should not replace prescribed antibiotics. Additionally, the diuretic effect of corn silk might lower blood potassium levels, making it unsuitable for those on prescription diuretics or with reduced kidney function. Pregnant women should also consult their healthcare provider before consuming corn silk water, as it may stimulate uterine contractions.
