I read about the benefits on Valerian Root in a book about depression. As I am suffering from depression I thought this could be very beneficial in helping me to sleep and let go of all the thoughts in my head at the end of the day.I have found that if I haven't been drinking any caffeine in the few hours before I go to bed then the Valerian Root knocks me out for the whole night and I've been getting a lot better sleep. Only times it doesn't seem to work is when I've had a drink of soda or tea not long before I've gone to bed, but that's to be expected.
