The lipophilic extract of the Saw Palmetto (serenoa repens) berries is the most widely used herbal preventive and therapeutic agent for benign prostatic hyperplasia (BPH). In clinical studies, saw palmetto extract has been shown to reduce subjective micturition symptoms, improve urinary outflow and reduce volume of residual urine with few adverse effects. While popular in the USA, Canada and Europe, recent studies have questioned its efficacy. While it may do Mr Scott no harm to try it, it may not be the most ideal treatment option to alleviate his symptoms.
