Lately I have been reporting on the success of the oleander based supplement Sutherlandia OPC against HIV/AIDS. Thus far, several hundred people (or more) have used OPC and it has been successful 100% of the time - as was borne out in a recent small scale clincal trial.
The reason I say "several hundred people (or more)" is that I do not know how many have now used it. At the beginning of the trial it was several hundred. Halfway through the trial, based on the track record of past use (in both HIV/AIDS and cancer), and the figures from the first 30 days of the trial (and likely also the fact that oleander has tested to be the most powerful immune stimulator known to man by a wide margin), a South African pharmaceutical manufacturing company jumped in and began making it on a large scale. The first run was 50,000 bottles and they are currently making an additional 10,000 per month - in the process enabling the price to be reduced from $90 for a one month supply of extract to $60 ($45 for the capsule version).
Here are two charts from the trial:

I much prefer the extract simply because that is what has been around for years and seen all the good results. In theory the capsules should be just as good - and I have heard no complaints, but I prefer to let them prove themselves as the extract has.

Look at the charts. Positive results for everyone at the 30 day mark, and better results at 60. Most people take it for a few months. If it were me, I would take the normal dose for 3 months or so and then cut back to a much lesser maintenance dose just to keep my immune system strong. And it should go without saying that a healthy diet and lifestyle should be followed for the rest of your life.

No problems at all with Vitamin C. The only things I am aware of that you may wish to avoid are blood thinners such as Wayfarin or Coumadin and cardiac glycosides such as Digoxin/Digitalis.
The main ingredient in OPC is oleander extract and one of the major active ingredient in oleander extract is a cardiac glycoside named oleandrin (and it also contains a handful of other cardiac glycosides in much smaller amounts). Even so, the amount of cardiac glycosides in a full dose of OPC is about 1/40th the amount in a dose of digoxin/digitalis.
