I Like olive leaf extract quite a bit. Usually when I am out to destroy pathogens I use a combination of of two or more of Colloidal Silver , oil of wild oregano, goldenseal and olive leaf extract. The combo has worked very well for me with a number of different problems - brown recluse spider bite, MRSA chest infection from Hades and more.
Again, congratulation on your success. It gives me great joy to see anyone beat cancer. Just be sure to keep toxins out of your body and environment, eat and live healthily, manage stress and make sure that you get optimum nutrition and you have great odds of never seeing cancer return.
