Probably a long term usage and exposure to Grapefruit-Seed-Extract might do the trick. I havent tried the liquid form yet so cant comment on its strength.
But all these elements are secondary. we first need to be cleansed throughly else these remedies/medicines wont be as effective. Wish there was something out there that could wipe out everything from your system 100% like drinking acid :) Since we know what acid is capable of achieving.
ANother thing i noticed is that when someone opts to a certain treatment, like Grapefruit-Seed-Extract for example. they give up on this product after a few weeks or months. I know everything adds up to the costs, but isnt it what we need to be fighting for.
