I have been taking this herb in a liquid form for about 5 months now along with Hops .I started taking it because I was having trouble sleeping through the night and not sleeping very long. The best thing I have noticed is that the tension that used to caused real pain in my neck seems to have gone or at least the pain has. I do think I am a little calmer than I used to be I used to get a very dry mouth that also seems to have gone. However, if I stop taking it the pain comes back. I still have some nights when I sleep better than others but I wake up later now between 5or6o'clock instead of 4. I hope this has beeen of use to you.
