The big majority of the thousands of people who have now taken OPC are in South Africa. Native South African Marc Swanepoel developed the OPC because of the huge HIV epidemic in South Africa as well as to help benefit indigent cancer patients there. I met Marc over five years ago when we were mutual members of a couple of health groups dealing with the home oleander remedy and the patented medicine version, Anvirzel - and we have corresponded ever since.
Until a handful of months ago, Marc sold his OPC only by word of mouth, charging only what people could afford and giving much of it away for free for those who could afford nothing at all, and almost exclusively in South Africa - which continues to be his primary concern. Since I have hosted the Yahoo Health Group "oleandersoup", I recognized that the OPC could really help fill the gap between those who were unable to afford the $2700 for a three month supply of Anvirzel and those who were reluctant to try to make the home remedy for relative pennies from an admittedly highly toxic plant (in raw form). So, I took it upon myself to try to help get the word out, and I am continuing to do so.
At the last report I had from Marc, when several hundred people had used OPC for HIV/AIDS, every single one of them had seen their CD4 counts reversed and all were still alive and well. Then, a few months ago a small double blind placebo controlled trial in a Johannesburg AIDS clinic was 100% successful and a South African pharmaceutical manufacturing company stepped in to produce OPC large scale - but again, primarily for South Africans. Now, thousands of people in South Africa have taken the OPC and the success continues to be 100% insofar as reversal of CD4 counts and overall health.
