Nettle Tea for Urinary Tract Health

Research suggests that stinging nettle (Urtica dioica) has a traditional history of use for urinary tract and kidney-related conditions, with some early scientific evidence pointing to potentially relevant mechanisms such as promoting urine flow and reducing urinary oxalate levels associated with kidney stone formation. The available evidence comes from a limited and mixed body of literature, including two narrative reviews, one animal study, one small human pilot study in which nettle was not the primary finding, and one historical analysis of Renaissance-era medical prescriptions — notably, no randomized controlled trials or robust clinical studies specifically examining nettle for urinary tract health were identified. Studies indicate that while these preliminary findings are directionally supportive, the overall clinical evidence remains sparse, and researchers across multiple reviews have emphasized that more rigorous human trials are needed before firm conclusions can be drawn. The research does not establish nettle tea as a proven treatment for any urinary condition, and readers should weigh the current findings with an understanding of their significant methodological limitations.
