Hi laura12 .....
Welcome to this forum of caring, supportive new friends.
I do not personally know anything about Essiac Tea, other than what I just googled and found essentially the same information you stated. That being said, there are many of us who would very much like to find a "natural" or "organic" way to get rid of our tumors. Personally, I am afraid to try experimental herbs/drugs that have not been proven as safe. Naturally and organically grown foods I am OK with and have embarked on a largely vegetables/meats/fruits diet. I feel much better but do not know if it would have any affect on a tumor.
Three years ago I experienced a regrowth of my acoustic neuroma and had it surgically removed a second time. My situation is a bit out of the norm because of the huge doses of radium I received as a kid. I am skeptical about adding more radiation to my head (even though in much smaller doses) for treatment.
My latest MRI (one year ago) still shows a "smidgen" of something and it is being monitored. So, I fully understand your situation.
Again, welcome .....
