I have been adding this to my evening cool down routine and I'm sleeping very well. This isn't really an herb to fall asleep, but it's more just for rest and better sleep. You can check the internet for all the possibilities, but in the capsule I think relaxing and letting go of stress is great. I like this product. Seems to taste right when I open a capsule to taste the powder. The capsules are easy to swallow and I am not having any odd effects, gastrointestinal or otherwise either. Really happy with this order.
