Definitely sounds interesting ... maybe next time I'm in the natural-food store (I was there about a half hour ago :-)) I'll see if they have some that looks as though it's from a respectable company, and think about whether I feel like trying it.

back when i was researching herbal remedies for depression, it came up in several sources, and i ended up adding it to the tea i concocted for a while (from a whole slew of supposedly anti-depressant herbs [1]). it's not cheap (1 fl oz C$15 at the time), and i can't really say anything much about its efficacy. i was drinking the tea during the atkins experiment, which means i don't know whether my generally higher energy levels were helped by it at all (as compared to the low carb intake, which has a very clear effect on it, because it's working now too, and i am not drinking the tea).

[1] ginkgo biloba, turnera diffusa (damiana), valeriana officinale (valerian root), scutellaria lateriflora (skullcap), tilia cordata/platyphyllos (linden flower), albizzia julibrissin (mimosa), melissa officinalis (lemon balm), panax ginseng, and the rhodiola.

I have taken it on and off for "general support".

I feel its effects are significant, but not pronounced. I also feel that when I no longer need it I feel a bit aggressive or a little speedy, so I stop taking it.

Since I'm dealing with a lot of background grief and depression this mild support keeps me feeling more on an even keel without getting weird. I have taken one cap each day and it seems like never for more than about 14 days in a row, then I feel that aggressive/speedy thing and stop.

I haven't used a particular brand, but have only picked it up where ever I am when I happen to need some. I have not noticed a difference in brands, for what it's worth.
