My wife just returned from Peru on a ceremonial retreat for 10 days. Many attendees have medical conditions they go to treat. The Shaman said they have had some success treating Parkinson's. I do not have any details of the kind of success they had my wife does not have Parkinson's and went for other reasons. This is just an inquiry as to find out if anyone has any information on treating Parkinson's there and if it was beneficial?
