Synopsis
Source of validity: Traditional
Rating (out of 5): 1
Cornsilk (Zea mays stigma), the thread-like styles from corn ears, has a long history of use in traditional herbal medicine for urinary tract issues, including cystitis and other bladder-related conditions. Traditional systems such as Native American medicine and various folk remedies in Asia and Europe have employed cornsilk as a soothing diuretic, believed to help reduce irritation in the urinary tract and promote urination, thereby potentially easing symptoms like pain and frequency associated with interstitial cystitis (IC). The rationale for its use is largely based on its reputed anti-inflammatory and demulcent (soothing) properties, which may help calm inflamed mucous membranes.
However, scientific studies specifically investigating cornsilk for interstitial cystitis are lacking. Most available evidence consists of anecdotal reports or extrapolation from its effects in urinary tract infections or general urinary irritation. A few animal and in vitro studies suggest cornsilk extracts may have mild anti-inflammatory and antioxidant effects, and possibly a diuretic action, but these findings have not been directly linked to efficacy in IC. No human clinical trials have been conducted to confirm safety or effectiveness for this condition. In summary, the use of cornsilk for IC is justified by tradition rather than science, and evidence is limited and indirect.
