Hi i want to post my experience using sutherlandia, a herb from South africa, used to treat HIV. A nutritionist recommended it to me after Glandular Fever. It has really worked well when it comes to energy levels. I have had post viral fatigue for many years. Recently i crashed for a month. I started on sutherlandia again and within 48 hrs i had recovered a lot. So i think it must help with post viral as well as glandular fever symptoms. I struggled to get it in the UK, but it is avaliable in the netherlands and germany. And south africa of course.
