Benign prostatic hyperplasia is a common condition in aging men that causes prostate enlargement and compression of the urethra, leading to urinary symptoms. The document discusses several herbal medicines - saw palmetto, nettle, pygeum, pumpkin, and lycopene - that may help treat BPH symptoms by blocking dihydrotestosterone, reducing prostate swelling and inflammation, and inhibiting prostate cell proliferation. A proprietary herbal blend containing these ingredients was shown to significantly improve BPH symptoms over three months without serious side effects. However, lack of standardization limits understanding of herbal products' effectiveness.
