Link for Sutherlandia OPC
http://www.sutherlandiaopc.com is the ONLY source. Sometimes people get it confused with plain sutherlandia frutescens or with an antioxicant popular in Europe called OPC, but that link is the only source.
I think it is quite simply the most amazing supplement on the planet. Cancer, HIV, Hep-C, various immune disorders, arthritis, thicker hair, and one I'll save for later . . .
Cinnamon is pretty amazing stuff - though it tends to lower male libido - and Vietnamese cinnamon is really good if you get it from a trusted source.
Oleander, well you know how I feel about that! It too was mentioned in the Bible btw. The other part of S-OPC, Sutherlandia Frutescens is pretty amazing too. Also known as the "South Africa Cancer Bush", the government of S. Africa is so proud of it that they issued a postage stamp in its honor.
According to the naturopathic PhD who devised the supplement, a couple of caps a day, especially when combined with N-Acetyl Cysteine, will ward off the flu for just about anybody. The other side effect I was saving is that it increases male libido. (So OK ladies, now you know what to do depending on which way you want your guy to behave - cinnamon or oleander - lol)
