I used it for about 2 weeks so I don't know what effect it had. You can go on line and get it at a much reduced cost through
www.herbalhealer.com. I went on the web site and was able to join free of charge. They sent me a 100 page catalog which included descriptions of their product line along with testamonials. They supply the patented essiac along with a 4 herb tea generic version which is much cheaper. It didn't taste bad. It is just very time consuming to make, but a batch lasts for about a month in the refrigerater. Blessings, Lu Ann. I forgot to mention, I'm on chemo and my oncologist allowed me to use it.
