The following link is to an essay written by
Tammie Ferris who ran an HS hotline some years
ago. She did tremendous research and has
written a very easy to understand translation of
serious research done by two doctors, Dr.
Samuel Thatcher, and Dr. Michael Birnbaum.
Please read it.
If you read my profile you'll see I've applied this
research to myself and have been in remission
for many years.
