Nettle Tea for Prostate Health

Research suggests that stinging nettle, particularly its root extract, has been studied as a potential support for prostate health, primarily in the context of benign prostatic hyperplasia and its associated urinary symptoms. The evidence base includes one notable randomized controlled trial of 620 men reporting substantial symptom improvement over six months, multiple systematic reviews and narrative reviews generally supporting its use alongside other botanical remedies, preclinical cell studies suggesting antiproliferative activity against prostate cancer cells in laboratory settings, and one animal study indicating possible effects on prostate size markers, though these findings do not establish effectiveness in humans. Studies indicate that proposed mechanisms include interactions with sex hormone binding globulin, aromatase inhibition, and in some preclinical models 5-alpha-reductase inhibition, though researchers note the exact mechanism remains unclear and the evidence base is less robust than that for saw palmetto, with the 2000 meta-analysis finding the available nettle-specific trial data at that time too limited to draw firm conclusions. Across the body of literature, nettle root is generally reported to have a favorable safety profile with few adverse events, but reviewers consistently call for larger, longer, and better-standardized clinical trials before definitive conclusions about its efficacy can be drawn.
