Valerian is an herb that's long been valued as a mild sedative, and now research is showing what tea enthusiasts have known for centuries. In a study of women, researchers gave half the test subjects a valerian extract, and half a placebo. Thirty percent of those who received valerian reported an improvement in the quality of their sleep, versus just 4 percent of the control group. In a another study published in the European Journal of Medical Research, investigators gave 202 insomniacs valerian or a Valium-like tranquilizer. After six weeks, both treatments were equally effective. And in other studies, valerian root has been shown to increase the effectiveness of sleeping pills. While researchers have yet to identify the exact active ingredient, they suspect that receptors in the brain may be stimulated to hit "sleep mode" when coming in contact with valerian.
