I tried it for several weeks for rectal cancer .. didnt notice any change. I'm since 'on' the Gerson Therapy Diet and will be sticking with it for 4-6 weeks, at which time I'll go back down for another scan.
Not saying Essiac doesnt work because I honestly didnt give it enough time. I just thought more of the GTD than Essiac, and didnt want to combine the two.
