Medical research has discovered that the active ingredient is icariin and is used to increase erectile function. One of the most important ingredient of vigrx is Saw Palmetto.
The medical journal JAMA published research showing how Saw Palmetto is effective for the treatment of men with symptomatic benign prostatic hyperplasia. Saw Palmetto has shown significant action in treatment of conditions associated with benign prostatic hypertrophy (BPH). Saw Palmetto extract works to prevent testosterone from converting into dihydrotestosterone, the hormone thought to cause prostrate cells to multiply which leads to an enlarged prostate.
Saw Palmetto’s largest uses today are as a supplement for reducing enlarged prostate glands, treating urinary tract problems and for improving body strength. Saw Palmetto is one of the few herbal remedies that are considered to be anabolic – strengthening and building body tissues.
