Stinging Nettle for Prostate Health

Research suggests that stinging nettle, particularly its root, shows promise for supporting prostate health in the context of benign prostatic hyperplasia and, to a lesser extent, prostate cancer, with the body of evidence drawing from narrative reviews, animal studies, laboratory cell experiments, and a small number of clinical trials. Studies indicate that nettle root may help reduce urinary symptoms associated with BPH, potentially by influencing hormone-related enzymes involved in prostate tissue growth, and one 2024 randomized controlled trial found that a combination supplement including stinging nettle was associated with reduced PSA levels and fewer unnecessary prostate biopsies compared to saw palmetto, though this trial was exploratory and involved multiple ingredients rather than nettle alone. Laboratory studies have also identified anti-proliferative activity against prostate cancer cell lines, and several reviews position stinging nettle favorably alongside other botanical options for urological conditions, though a 2000 systematic review of BPH supplements found the available evidence for nettle at that time too limited and poorly reported to draw firm conclusions. Overall, while the direction of the evidence is generally supportive, most findings come from preclinical research or reviews rather than large, well-designed human trials, and researchers consistently call for more rigorous clinical investigation before definitive conclusions can be drawn.
