lookingforanswers,
I forgot to mention, make sure your friend takes the herbs and cleanses in Dr Clark's book allong with zapping. Here is a link to her book. http://sbherbalremedies.com/books/the_cure_for_all_diseases.html Also, sorry if my post doesn't make much sense up there, I was a little tired this morning :D Hope he gets well soon! God Bless.
