Horsetail for Urinary Tract Health

Research suggests that horsetail, when used as part of a multi-herb combination supplement, may offer some benefit for urinary tract health, particularly in reducing symptoms associated with overactive bladder and urinary incontinence. The available evidence comes from two randomized, double-blind, placebo-controlled trials, one of which reported statistically and clinically meaningful improvements in urination frequency, nighttime trips to the bathroom, urgency, and incontinence events in adults over eight weeks, while the second trial, focused on bedwetting in children, has only published its study protocol and has not yet reported outcome data. An important limitation throughout is that horsetail was not studied in isolation in either trial but rather as one component of a proprietary three-herb blend, making it impossible to attribute any observed effects specifically to horsetail alone. Overall, the evidence base is small and preliminary, and further independent research would be needed before drawing firm conclusions about horsetail's role in urinary tract health.
