Basil has been by far the best remedy for my insomnia. I bring about 2 cups of water to a simmer, add 1/2 of a tablespoon of dried basil, turn the stove off, and let it sit, covered, for about twenty minutes. I've substituted a bruised sprig of fresh basil on occasion with the same wonderful effects. I start sipping on this tea about two hours before bed, and it knocks me out every time. I've upped the ammount of basil in the tea or the ammount of the tea I drink on occasion but the above measurements are the average ammounts that work best for me.
