Re: CFS and enterovirus'

 Do the herbs pao d'arco and elderberries kill enterovirus'?

Both of these are antiviral, but for enteroviruses I would focus primarily on andrographis, which has been shown effective against enteroviruses, and chaparral.  

Elderberry is good, but the same problem of a high tannin content biding other herbs is present so it would have to be taken alone.
