Here's something worth checking into. Wake Forest University Baptist Medical Center has noticed a trend of patients asking about or insisting upon taking herbal remedies and suppliments. As such, they've responded with an informational site about herbs and suppliments.

The best information seems to come from the Longwood Herbal Task Force.
Yes, I'm quite skeptical. No, I don't see a single herbalist listed as a staff member or consultant. But a preliminary glance of the data doesn't appear to be that bad. It looks as though they have researched valid and pertinant databases and other documentations. Of course, they heavily use clinical, in vivo and in vitro studies while glossing over or simply neglecting to mention traditional accepted uses.

But it doesn't look all bad. I'll spend some time on this site and report back. At first glance, they have a 25 page in-depth monograph on Silybum marianum. Wow!
