Its historically been where lots of abuse happened - quacks offering miracles; legitimate researchers overstating the hope and downplaying the suffering involved in 'new' treatments. So there's a lot of rules in place.
I'm not sure if you are aware but in Africa right now people infected are actually going to see the quacks and shamans because they have no other option. Maybe it's time to think about providing them with something that has more scientific ground to actually work.
I'm not sure there are anything but shamans there - once I heard of the doctor that hid his infection and exposed 200+ other people, I have lost all faith in local doctors to accomplish anything.
Exotic cures are sure exciting to talk about. But for a disease that can be stopped cold in its tracks by washing hands and effective quarantine, they're having a bucket of trouble accomplishing anything. Maybe its a little blue-sky to be adding complex drug protocols to the plan.
