What's that other quackery where you don't actually do anything to help heal somebody, other than wave your hands around and steal their wallet?
Psycic surgery qualifies, although that usually involves some slight of hand where you produce blood and some sort of gristly chunk you claim you removed via your tool-less, non penetrating "surgery".
But what you are probably thinking of is Reiki, which is a perfectly valid guided meditation technique (when advertised as such).
Both of these techniques can produce real healing. Expensive (in terms of time invested or cash, either way) placebos are provenly more effective than cheap ones, and often more effective (and safer) than over-marketed medications whose main claim to optimal effectiveness is that their patent has not yet expired.
Or maybe you were referring to politics? That involves a lot of hand waving and theft, but can't produce any real healing...
