Ok.... So one of you is saying sutherlandia OPC works and one of you is saying it doesn't or may which is it??
As the links to the studies showed the Sutherlandia OPC works in a petri dish, against SOME cancer cell lines. But as has been shown time and time again just because something works in a petri dish this DOES NOT mean it will work the same in the body. I give several examples of how petri dish studies were improperly associated with the same effects in the body in this post:
does Pau darco work or will that have differing views too?
I have not seen anyone ever claim that pau d' arco does not work. But it is more effective for leukemias, lymphomas and polycythemia, which again are often viral in origin. Pau d' arco contains 18 antiseptic antiviral anthraquinones and napthaquinones as well as antiviral quercetin.
The difference is that the research has been done on pau d' arco so its chemistry and actions are well known.
