It is interesting to note that two popular alternative cancer treatments, Cantron and Protocel (pretty much the same treatment) are also effect at fighting a wide assortment of viruses. I have always promoted using Cantron (less expensive) as a cold or flue treatment because if you find that it works on your viruses (about 50% success rate), it will most likely work on cancer for you. I explain how to check this in the "Cancer Proofing" section of my Prevention page at: http://alternativecancer.us/cancer-prevention.htm
