I used it and found it helpful. There is a study somewhere that suggests it works better after using it for several days. I mainly used it during the daytime to control anxiety (using smaller doses). If I took too much at night, I noticed my breathing became slightly irregular and that kept me awake.
Valerian has a very "distinctive" aroma, I can't imagine drinking a tea. I took a capsule with the raw root. I picked a brand name that I researched on the web as being ok. I've read some brands are not as potent as claimed.
I haven't been using it recently. I moved on to more powerful sleeping pills for insomnia and my daytime anxiety has lessened.
