Nettle (Urtica dioica), commonly known as stinging nettle, has a long history of traditional use in supporting urinary and bladder health. Folk medicine practices, particularly in Europe and parts of Asia, have used nettle as a diuretic and to help relieve symptoms of mild lower urinary tract issues, such as those related to benign prostatic hyperplasia (BPH) in men. Traditional herbalists often included nettle in formulations aimed at improving urine flow and flushing out the urinary system. The leaves and roots have both been used, sometimes in combination with other herbs.

Modern scientific research offers limited but emerging support for these traditional uses. Some studies suggest that nettle root extracts may modestly benefit urinary symptoms associated with BPH, potentially through anti-inflammatory and anti-proliferative effects. However, specific research targeting general bladder health or the use of nettle leaves (rather than roots) is less robust. Most clinical evidence focuses on BPH symptoms in men, with less attention to bladder support in the general population. Overall, the use of nettle for the bladder is primarily justified by traditional practices, with only preliminary or indirect scientific support. More rigorous, targeted studies are needed to confirm its efficacy and safety for bladder health.
