Of course it works. I successfully cast my schizophrenia demons into a herd of swine several months ago. The Satanic Jew-run Extraterrestrial Brave New World Deadly Paramilitary Pharmaceutical Advancement Committee found out about this, however, and have been sneaking into my house at 3:30 am every morning in order to inject nerve-death squalene into all of my life-giving organic vegetables in an attempt to restore my dependence on mind-imprisonment chemical castration haloperidol!
HAving worked in the mental health community in the rural South, I wish I could say I had never heard some wayward kid's youth pastor give EXACTLY this advice to the parents of a child in serious need of mental health treatment.
A vaguely related tale. Many years ago my Grandmother, wintering in Florida, came down feeling very weak and having chest pains. My Uncle knew just what to do. Take her to a faith healer! This caused some significant family drama which ended in Grans going to the hospital, having heart surgery, and getting better.
