the sitz bath and clark 21 day mop up explained in her cancer book works well for the brain as well as seeking a good chiropractor always FIRST who will make sure all the plates are in the correct place.
As for dousing, Dr. Christopher took on all who would submit to a blind test and in 50 years they NEVER EVER found one person who could douse/muscle test in any way shape of form. The believers want people to believe "they are special" and the books say it all has to do with the thymus/brain function. I have been tested by just about every method out there, everything from finger nail clippers, sugar cubes, finger testing, etc., etc. and we just ignore it. 99% of the people that do it are selling products and use it to condem one so they can sell theirs to you.
Nature's Sunshine promotes these methods as a way to trick people as do all the people selling Nikken magnets, etc.
