^Ah, semantics I disagree on. Not because they're necessarily worthy, but I wouldn't class them as 'scams' - well, I don't know enough about homeopathy to say it wasn't started as a scam... and I'm willing to bet that, like human 'clairvoyants', there are many scammers in the 'animal communicator' business, but I think when things are developed & marketed by people who actually believe in them, this may well be misguided/downright wrong, but it's not a 'scam'.
Okay then, how about a little bottle of 'Dr Good', taken from a Chere song!
Live blood analysis is a definite scam
Dark field microscope is used
The scammer,puts a patient's blood on , with cover slip , then has the patient look at how awful his blood cells looks in his wet prep, not a preserved stained slide)
The microscope is focused on the outer edges, where of course, cells will start to crenate
Patient is sold some supplements, few weeks later, LOl and behold the healthy red cells-but the microscope is focused on the center of that slide, where blood has not yet dried out
I can tell you afew others, as we had patients come tot he clinic in Olds, right after having had the live blood analysis done, by the local Chiro
One woman was told she had to take a bunch of supplements, because her blood was loaded with yeast.
Now that was not going to fly past me, having worked in oncology, knowing when yeast appeared in the blood (not urine ), that person was on his way out, white cells defense gone. This woman was hale and hearty.
I took her blood, prepared a smear, and asked her to show me those yeast.
They were her platelets.
Another woman I know, at a horse meeting, told me she did not need Pap smears any longer. Intrigued, I asked why.
Well, her live blood analysis specialist told her that he could see if she was going to get cancer, five years in advance.
Okay, purist example I can find of an actual scam, where the perpetrator knows he is scamming, pushing snake oil
