Okay, well I went ahead and just took a whole bottle of extract (maybe 30ml, don't know strength, supposedly like 30-60 doses, made my tongue numb) and I did notice SOMETHING. It was better than nothing, I'd say, but not equivalent to any dose of benzo (not even 2-5mg of valium). Maybe like a beer. Unique, really. Kinda nice, not worth it. But thanks much for advice.
EDIT: OK, actually I'll say it was like 2-5mg of valium plus a beer, and it DID beat my anxiety. So, yeah, it was kinda cool and if it was around I'd do it again.
