Corn silk extract acts as a diuretic, meaning it helps flush water through the urinary tract and out of the body. It is also a demulcent, which refers to its ability to soothe urothelial surfaces. (x) Thus, one of the most common uses for this extract is to help maintain the urinary tract’s health or ease specific urinary ailments. (x)
2. Flushes Out Kidneys
Corn silk extract can also reduce kidney stones by flushing out the mineral debris that can accumulate in the urinary tract. A study of kidney repair using the silk on rats supports the extract as a useful solution for repairing damaged kidneys. (x)
3. Prostate Health
Benign Prostatic Hyperplasia, or BPH, is a common occurrence in men marked by an enlarged prostate gland. While usually not harmful, it can cause troublesome symptoms, including increased frequency and urgency of urination.
4. Reduces Blood Pressure
Research suggests that corn silk extract can help with hypertension (elevated blood pressure), thanks to its high potassium content. A study supports its effectiveness as a dose of the extract significantly lowered participants’ blood pressure within hours. (x) Because hypertension is a potentially serious medical condition, it’s essential to check in with your healthcare professional before managing it with supplements.
5. Lowers Blood Sugar
When blood sugar is chronically elevated, as is often the case in people with diabetes, it’s called hyperglycemia. Uncontrolled hyperglycemia can cause a variety of symptoms and even lead to a medical emergency.
Corn silk extract is a traditional “anti-diabetic” and can help manage blood sugar levels. Specifically, it can help reduce blood sugar during times of hyperglycemia. Animal research found that water extracts of the silk lower blood sugar levels in diabetic mice by increasing insulin and repairing the pancreas’ damaged cells — the organ that produces insulin.

Corn silk has anti-inflammatory properties — phytochemical. Phytochemicals are nutrient compounds you find in plant foods. In studies, researchers noted an interruption of the normal functioning of many pro-inflammatory compounds. Taking the corn silk increased vascular permeability while inflammation reduced. (x) For those dealing with chronic inflammation, corn silk may help manage symptoms with fewer side effects than standard anti-inflammatories.7. Antioxidant
Oxidation describes the normal process that occurs during oxygen metabolism in the body. This process creates “free radicals,” which can damage cells unless neutralized by antioxidants. Oxidation provokes chronic conditions such as heart disease, diabetes and cancer. (x) Corn silk extract is a rich source of natural antioxidants — particularly flavonoids. Studies found it reduces oxidative damage in mice at about the same level as vitamin C. The supplement may also encourage the body’s own antioxidants production. (x) (x)8. Anti-Fatigue
Corn silk extract may also help increase endurance and fight fatigue. In a study, animals given the extract had higher glycogen levels (fuel) in the liver and showed greater exercise tolerance. (x) It can also reduce oxidative damage in the muscle after strenuous exercise, improving the recovery rate. (x) For those looking for a pick-me-up before or after the gym, this extract may be for you. But, talk with your physician before starting any new supplement.
