Unfortunately, as long as IV/C has the potential to bankrupt hospitals, it doesn't matter how well it works.
And for those still reading , our own (unintentional) research has unequivocally demonstrated that not all IV/C are created equal!
There are basicallytwo major forms of IV/C - the "mild" and currently only commercial form (from Bioniche) is buffered ascorbic acid. The product is vitamin C, and can flush toxins, say after dental work.
In my opinion, the pH is probably too low to take the commercial I/Vs continuously w/out vein damage.
On the other hand, the I/Vs developed and used by the late Dr. Robert Cathcart, III, MD, are not only safe (proper pH) but perhaps an order of magnitude more effective! (My current alt. doc didn't believe there could be much difference, but now is engaging on a side-project to have both analyzed to identify the difference so that he can write a paper.) THE DIFFERENCE IS THAT DRAMATIC. The so-called Herxheimer reaction is the give away. If you are looking for maximum therapeutic effect, the IV must be sodium ascorbate mixed per Cathcart's instructions PDF: http://www.vitamincfoundation.org/ivc/civprep.pdf VIDEO: http://www.youtube.com/watch?v=Zgi-7xPrCAg
And now you can get the Cathcart style sodium ascorbate for IV from a few compounding pharmacies (with a prescription).
