After someone mentioned in earlier post (you perhaps?), looked for info other than just anecdotal.

Found this study reported in the Journal of International Medical Research. It's lengthy, and it's technical (read: over my head <img src="/images/graemlins/crazy.gif" alt="" />), but my original source site to the document summarized with this:

"...a group of people all suffering from the flu...gave each experimental subject one tablespoon of Sambucol (an elderberry extract developed by a Dr Mumcuoglu) four times a day for five days, while giving the control group a placebo (four times a day for five days).

At the end of the study, those getting the Sambucol recovered from their flu in 3.1 days (average) while the control group averaged 7.1 days for their recovery...there have been no studies on the preventive use of Sambucol, but many people do swear by it and take it regularly during the cold and flu season."

As they say, YMMV.
