One such product is is Nervexol by Iaso Nutra Group, which is designed to provide neuropathic relief.This supplement is advertised to relieve the nerve pain within “10 seconds” only. To be honest, it is a very bold statement, and considering Nervexol is a dietary supplement, many people might not believe it. But if you go through its ingredients and see names like California Poppy, Passion Flower, and Corydalis you would get to know that Nervexol pills are loaded with the power of nature to fight against nerve pain by working on its root cause.
