i rarely find herbs or blends that stand up to their claims, particularly with regard to relaxation and calming, especially not if you are looking for something that will work with a single dose and within 15-30 minutes and then continue to have a sustained effect, this blend actually does work.... and you don't even have to exceed the recommended dose of 3 caps. this is a well thought out combination. i can't say how it continues to work with daily use or using it multiple times a day but a single dose definitely delivers good results.
