After several episodes of erectile dysfunction i've resorted to buying a pill called vigorx plus..is it safe and can it remedy my situation permanent?

Unclear benefit: VigRx plus is a dietary supplement. Most supplements have no credible scientific evidence of benefit. This one contains a set of herbal extracts that may or may not do what is claimed, including Epimedium Leaf Extract, Damiana, Gingko leaf, Ginseng, Saw Palmetto, Muira Pauma Bark, Catuba Bark. A more effective and proven option would be a prescription med such as sildenafil (Viagra).
