17 randomized trials of saw palmetto monotherapy in mostly white men with BPH were examined with study lengths ranging from 4-72 weeks. Saw palmetto was found to be no better than placebo for reducing lower urinary tract symptoms or maximum urinary flow rate. A long-term study found no effect on nighttime urination frequency, but pooling shorter-term studies found a reduction in frequency of 0.79 times per night on average, although the studies were heterogeneous. Adverse events were not statistically different from placebo.Funding issues for this study:
