This is the first time I've ever heard of the Amish Healer. What an amazing story. I've seen on the internet good natural healers bad mouthed, like you have said. Of course, the web site I saw is run completely by the main stream health profession. Money seems to rule everything - even compassion for the sick.
If you go to a dr. who owns a nice car, has perfect sparkling white teeth, talks about working out at the gym, etc... a red flag should go up! The doctor has to pay for that stuff somehow. This was true with a real estate agent we got tangled up with - heavy smoker with shiny sparkling teeth. I thought then, she needs our money to pay for her teeth job, nice clothes, expensive makeup, etc. She got it, and we got snookered. Beware!
I hope and pray things go well for this Amish Healer and those who help him.
