Valerian
Valeriana officinalis

It turns out that the Pied Piper may have used more than just his music to lead the children out of Hamlin — old accounts of this story suggest he also hypnotized them with valerian! Although it isn't really a hypnotic agent, valerian IS helpful for restful sleep, for which it has been highly valued for more than a thousand years. At least 100 products sold in Germany contain valerian as the active ingredient. Valerian can help you feel calm. . . so that you can get the sleep you need.
