Query: everyone should read this book...

my brother in law got malignant melanoma and after several surgerys and chemo treatments it kept coming back,so the Dr stopped all treatment and we went home with very little hope then i was shown the Essiac Report,when i started reading it i could not put it down and somehow i knew it was our answer so he started on the herbal tea right away and i am happy to say he has been free from any malignant melanomas for 4 years now and i am very thankfull for the book...it was a sign from God for us and i highly encourage anyone to read it, you will not be sorry...
