I too have been taking Essiac...for almost 4 years now, I was diagnosed with terminal stage 4 stomach cancer that had already spread to my liver, I was given eight months to live and I am Cancer free now almost four years later. I also take Pau d'arco tea which I would recommend to anyone, my tumors shrank rapidly when I added Pau d'arco and have never returned.
You must keep drinking the teas though at a reduced dose once the cancer is not visable any more.
Incedently when I first started Essiac I also bought the one with Rene Caise's picture on the box but for the last 3 years use one made with herbs purchased from a local herb farm. It is much less expensive and in my opinion just as good or maybe better.
The herbs are fresher and not combined until purchased, I have read that herbs should be stored seperatly, some of the expirery dates for the expensive pre-packaged stuff are a couple of years down the road ! I will post a couple of web site addresses with info about the teas.
Good Health to all, never give up its just a matter of finding the right alternative that works for your Cancer in your specific body. It's just too bad some of the billions spent on researching new pharmaceuticals couldn't be diverted to natural therapies that seem to work much better.
