never tried that brand, but do know that valerian works very well.
Do make sure there isn't Kava Kava in it, as there is still testing going on about it causing acute liver failure. (so far, they're thinking its the companies who cut corners and include stem and leave kavalactones. Traditional has always been root) It's highly unlikely it'd happen, but it's better to play it safe YK?
Also be careful about the way you administer it, as it smells very strongly like dirty socks.

Like repulsively strong. I can't even hold a capsule of it without having to wash my hands afterward. So just keep that in mind. I wouldn't be surprised if there are other herbs in it to mask the smell/taste. if not, give it straight, but with a chaser, don't dilute it, as it's such a strong taste in my experience that it'll make the diluted liquid taste bad, and the whole dose won't be taken.
And it's quite safe from what I know.
Hope that helps even though I don't have experience with the particular brand.
