Trevor Marshall is the ultimate quack. The 'protocol' is old news, and thankfully so, because hundreds of patients nearly died trying it, and at least a half dozen actually died, mostly from kidney failure.
It's based on a hypothesis for sarcoidosis, and has no studies to back it up, not only for sarcoidosis, but especially for all the other diseases Marshall claimed it would cure.
Yes, CURE. And yet 12 years after he appeared on the scene, he's still taking Benicar, even though he told everyone that they'd only need it for a year or two.
Read the comments at the link and perhaps you'll understand why it's so dangerous.
