Tribulus Terrestris for Urinary Tract Health

Research suggests that Tribulus terrestris has been identified in the scientific literature as a plant of interest for several aspects of urinary tract health, including potential antibacterial properties relevant to urinary tract infections, possible protection against obesity-related kidney damage, and a role in reducing urinary oxalate levels associated with kidney stone formation — though these findings come primarily from animal studies, cell-based experiments, and one systematic review of herbal medicine, rather than robust human clinical trials. Studies indicate that a multi-ingredient supplement containing Tribulus terrestris showed improvements in lower urinary tract symptoms in men with benign prostatic hyperplasia, though this was an uncontrolled observational study without a placebo group, making it difficult to attribute the effects to Tribulus terrestris specifically. The evidence is further complicated by safety concerns: at least one published case report documents severe kidney failure and liver injury in a patient following Tribulus terrestris supplementation, and animal combination studies have noted minor changes in kidney and liver markers, suggesting the plant is not without risk. Overall, the current body of evidence is preliminary and mixed in nature, and researchers across multiple studies consistently call for larger, well-controlled human clinical trials before firm conclusions can be drawn.
