The cancer fungus has been modified intensely so people won't recognize it as a fungus (where do you think all that 'research' money goes to, anyway?). The 'elites' make billions of dollars off it, and it's well worth the money to them that you never find this out. If it weren't a fungus, which is what I treated myself for exclusively, it wouldn't have gone away.
Olive leaf extract works against fungus pretty much. It's never helped with any other pathogen much at all. But since fungus is so silently prevelent, the olive leaf appears to help with those other things because it kills the fungus and allows your immune system to fight the other things better.
