herpes roster

Help us My wife and I have herpes roster and for a few years now but it has affected my wife so bad in the past 4 months that she has not had any relief and taking valtrex has not helped in the process in going away for a day and they just come back with a vengence. Is there any thing as far as herbs go that has helped or I found something new called choraphor is this any good. I also want to add that my wife has hardly any imume system left and when taking something for any length of time it seems as thou her system gets imune to what ever she takes for a a length of time and it will not work. Please help me in this quest to help her out so she can get some kind of relief
