You might wish to take a look at the various success stories posted at the Oleander Support Forum or the Cancer Alternative Forum at CureZone

as well as the "Oleander Series" of articles at:
http://www.tbyil.com/articles.htm
I wrote those articles as well as a book about oleander and yes I promote and advertise Sutherlandia OPC because it works. You will note on my website that there are no affiliate links to the product, just a link to the main website.
One of the success stories happens to be my own 86 year old uncle.
For those who wish to look outside the box, I will note that the Sutherlandia OPC (or other forms of oleander, including the patented medicine Anvirzel - one of two oleander based drugs currently in FDA trials) works particularly well when combined with the Budwig flaxseed/cottage cheese diet and other healthy dietary and lifestyle choices.
Whatever you decide, I wish you all the best.
