Powwowing or Powah - PA Dutch Faith Healers

I don't know much about the subject but believe people coming to my chat will find this very interesting. I understand there are still people practicing it based on an article in the Philadelphia Inquirer www.philly.com/inquirer/front_page/20091005_Another_medical_alternati
