I can't say that I have experienced any sleep benefits myself from drinking this 'tea', but it certainly makes for a very good relaxing night time infusion with its delicate floral flavours. Not something I would necessarily drink everyday but makes a nice change.
I like this tea and it is soothing. I feel me sleep is more deep with this tea. The only problem for me is having so much liquorice, which gives a sweet taste that stays in the mouth, but that's just a personal thing. It is a great tea no matter what.
If you have trouble getting to sleep or staying asleep then this is the best tea to have, it doesn't taste wonderful but you get used to it though and after a while the taste doesn't bother you. I would highly recommend it.
This is a really good blend of herbs. I love it. I tried other teas with valerian, but this is the only one that tastes pleasant. I have to add that it's way too expensive compared to my local grocery store.
