actually i started taking it after my cold was full blown and by the next day i was almost normal.

placebo? maybe, but then again 25 years ago the doctors poo-pooed us women for insisting that yogurt helped prevent yeast infections. And since that time it's been medically proven that yogurt does work! or cranberry juice for bladder infections...

I could go on and on...but remember that some of the best remedies are found in plants and minerals ...digitalis and taxol are just two that come to mind.

Also benefits have already been proven with such common things as red wine and garlic.
