Several discussions recently have included side-discussions about the incredible cures for diabetes that we all are missing, sage advice delivered from the unwashed masses. Sometimes, it's pretty funny, sometimes incredibly audacious in its idiocy, always ill-informed.
So, this got me thinking about some of the quackery I've seen in my life. There have been some doozies. Thought I'd start a discussion for us all to share, laugh, and have some fun. To that end...
Perhaps the biggest BS treatment I've ever encountered was something called Radionics (link is wikipedia, pretty good article). The idea is the body has all sorts of oscillating electric fields at different frequencies that can be measured to diagnose any and all illness/ailment, and then injecting radio energy at the right frequencies will heal the problem. Here's a brief excerpt:
According to radionics practitioners, a healthy person will have certain energy frequencies moving through their body that define health, while an unhealthy person will exhibit other, different energy frequencies that define disorders. Radionic devices purport to diagnose and heal by applying appropriate frequencies to balance the discordant frequencies of sickness. Radionics uses "frequency" not in its standard meaning but to describe an imputed energy type, which does not correspond to any property of energy in the scientific sense. 
My mother-in-law, heavily into alternative medicine, got sucked up in this one time. Went to a seminar, spent thousands on a "device", etc. etc. One day we got a call from her in Socal (I'm in northern cal) saying we should send a polaroid of me (has to be an instant picture -- where do you find a polaroid camera these days?), so she could put it in the machine and cure my diabetes. Apparently polaroid photos also capture a profile of your radionic something or other. Those primitives in the jungles who were afraid cameras would capture their souls were apparently on to something.
Anyhow, you can imagine how I reacted to all this -- after hanging up, of course. I still laugh. Anyway, we sent the picture (have a polaroid camera at work). That was 10 years ago.
I still have diabetes.
Haven't heard about radionics for, oh, probably 7 years now. She's moved on to Dr. Wallach and his pig pak, chelation, and some other stuff :-)
