After reading your post it reminded me of my step-dad, Walt, who passed away in 03 of brain cancer. Originally it started as prostate ('98) and then progressed to bone and then to brain. He had the prostate cancer for many years and managed to keep it under control via many different methods like... doctor recommendatations such as radiation implants, stricter diet protocals, those big ole crazy mushrooms that you grow and then drink in a tea - Gombocha.. I think.
In the beginning of '02 he was diagnosed as having bone cancer, so the cancer had progressed significantly. He was given a year to live. At that point, or somewhat thereafter, he began the Essiac Tea. Throughout that year he had very little pain. We were all so thankful and amazed that his pain levels were so manageable, as bone cancer is supposed to be awfully pain-filled - according to his doctors.
Sadly in the middle of that year he left off making and drinking the tea due to his father coming down sick and needing a caretaker. Within 4 months he was diagnosed with brain cancer. (I had never heard that if you leave off taking the Essiac your cancer will progress with a vengence, but that seems to be the case with my Dad too!) He passed in January of '03.
I must say that I believe in the power of Essiac tea. I think it caused my Dad to have a much more pain free and liveable life during his last year. I mean he was super active until about 2 months before the end.
Please read "Calling of an Angel" by Gary Glum. It's an interesting book that describes the origin of Essiac tea. There are lots of people out there who want to capitalize on Essiac, but they are not doing/selling it the way Rene (the discoverer) would have done it. Never use a tincture. You must use the dried herbs and follow Rene's recipe! Also I believe that this website - http://www.larrywinfield.com/recipe1.htm - is quite informative regarding the actual original prescribed doseage.
May God bless you in your search for healing!
