Actually I used to practise small circle
This pranic healing I am referring to is the one as promoted by Grandmaster Choa Kok Sui. I read about it in a Inside Kung Fu article. Alledgedly, practitioners can heal broken fingers in minutes and make a room smell of a frangance like rose etc.
But the thing I find funny is, the author describes newbies who trained for just a few hours to be able to take blows from heavy objects to the body. While they werent exactly slashing themselves with knives (I think), if this is true then quite a few iron body practitioners would feel like they've wasted a few decades....
