The plants used in our All natural antiviral treatment have been tested, researched, and written about for over 100 years. Why don't they get more attention? Pharmaceutical companies cannot patent a natural formula, so the profit margin doesn't make sense. There is a theory that many illnesses could be treated naturally, but who would make money on that? A question we have to ask ourselves; what do you believe? The testing we have done, to get this far, cost a small fortune, a big risk to take, when we cannot protect our formula from copycats. Look at our science page for links to peer reviewed studies on the plants that we use to make BVS.
