Herbal Studies Not Turning Out So Well

A spate of recent double blinded, controlled trials for herbal therapies have, unfortunately, not turned out so well.  A large European study, of over 600 patients, concluded that Feverfew was only mildly, if at all, effective for headache.  Gingko was in the news recently, with conclusions that it was NOT helpful for memory loss.  In addition, Echinacea (used for viral colds, etc) was recently stated to not have worked better for this than placebo.  These results are discouraging, given the fact that we want these milder alternatives to truly work.
