Saw Palmetto
Saw palmetto, scientifically known as Serenoa repens, is a small palm tree native to the southeastern United States. Traditionally, it has been used by Native Americans for various health issues, including prostate problems and urinary tract issues. Modernly, saw palmetto is widely used for its potential benefits in supporting prostate health, reducing urinary symptoms associated with benign prostatic hyperplasia (BPH), and possibly aiding in hair growth by inhibiting the conversion of testosterone to dihydrotestosterone (DHT). While some studies suggest benefits, others have found mixed results, particularly regarding its efficacy in treating BPH symptoms compared to a placebo.
