With viruses I don't think "cure" is the correct word to use. They are either active or they go dormant. We are trying to get the virus to become inactive or go dormant.
I'm doing very well on Dr. Zhang's herbs for 1 year now. But still looking for something to make the virus go dormant with natural methods. I know of people who succeeded with drug therapy but then later took some other drug for another condition and it came back. So it is a lifetime project. The main thing is to strength the host (your immune system).
