What plant cure herpes?

As I know of every doc's will tell you what is nothing will cure herpes viruses and it will follow you to make you suffer for the rest of the life. But to my opinion is just that the scientist don't make any new experiment for this cure, even though on my belief is if the god make this planet, and this world will have something called cure if is not why we have plant's at the first places. So why don't they seek on the new assignment that actually work on it. I know out there were over million nature plant that are very useful to cure this torture disease is just they need to found something new.
