A search of your site didn't turn up any reference to this topic, so I thought it was worth a post.
I heard about cesium chloride at the emergency medicine conference in Darwin (Australia) last week. Apparently the alt health freaks are using it for cancer, taken as an oral liquid. I know that trying to get into the mind of an altie is a serious mistake, but a. how on earth is taking a reactive metal salt in any way better than taking actual medication, and b. I can't imagine anything more obviously 'chemical' and non-natural sounding (well, apart from maybe polonium), so I'm a bit staggered that this falls into alt med's lexicon.
Jaws dropped all around the auditorium as a physician described how a man turned up unwell, with significant cardiac arrhythmias, and eventually admitted to dosing himself regularly with the stuff.
Anyway, google, as ever, turns up a wondrous store of information on cesium - venture to the wilder reaches at your peril!
BTW, should you rogues ever make the long-promised journey to Australia, I'd be happy to welcome you to Tasmania, home of some of the strangest and most famous marsupials and montremes in the world...
