Dr. Pannel also recommends valerian root for anxiety. "Research shows that when taken, it increases GABA or gamma aminobutyric acid, which is a known neurotransmitter that produces a calming effect," she explained.

(Of course, you should always talk to your doctor if you're having trouble sleeping.)
