I've used magnets for healing, for painful joints, and lately for a small tumor beneath the skin. They ALWAYS prove worthwhile! The tumor would actually be smaller in size after having taped the magnet onto it all night long. I consider a neodynium magnet one of the best cancer treatments available but I think it is something mostly unknown. Also very helpful is infra-red light.
The magnet works, it's cheap and it doesn't wear out. The big confusion is which side to use. For almost all instances you want to use "Bio-North" side which is "Magnetic South". "Bio-North is the actual magnetism found at the geographic North pole which is "Magnetic South" The Red (North Pointer) of a compass will point to the "Bio-North" side of the magnet (which is also called Magnetic south. Big, big confusion arose about this due to the way they use the terms.
