I disagree with several things in this site. First of all not all alternatives are slow to take effect. Ozone kills cancer cells faster than any other therapy I have found, conventional or alternative. Secondly, it is not that hard to remove cellular debris from the brain. Tumors tap in to our own blood supply to feed, and blood is a major component of the body used to remove toxins. As far as keeping swelling down this is easy. Controlled hyperventilation is commonly used to reduce intra cranial pressure. DMSO is not something to fool with unless you REALLY know what you are doing. I don't care much for Colloidal Silver either for various reasons. As far as their claim of MSM being natural, this is misleading. Commercial MSM is a complete synthetic. It is manufactured by heating the industrial solvent dimethylsulfoxide (DMSO), a byproduct of the paper making industry. When the DMSO is heated it adds an oxygen atom creating DMSO2, otherwise known as MSM.
