In the 1930s my mother needed help when the doctor could not help my brother.
The problem was infected ears! They drained all the time and had a bad odor.
after several weeks of treatment by the Dr. He made a remark when leaving one friday night, May be Aunt Kate could help Bob.My mother had an aunt Kate who pow wow,d on 2 visits bob was recovering, when the Dr. made his next visit the following week. Bob was about cured.
I do not know if Pwo wow is parcticed now, and can find no books about it. Can anyone help
