Did you know that the root of the valerian plant has been shown in some studies to speed the onset of sleep and improve sleep quality? Some people hold that valerian tea along with motherwort, chamomile, and catnip brews, none of which contain caffeine, will help make you drowsy. According to Timothy Roehrs, PhD, a senior scientist with Henry Ford Sleep Disorder and Research Center in Detroit, it may be less any property of the actual tea and more the power of a relaxing ritual as you get ready for bed. And speaking of tea, aromatherapy works for some people, lavender for example. Studies have shown that lavender is a cheap, nontoxic sleep aid. Find a spray with real lavender essence or oil and spritz it on your pillow before bedtime or try a lavender-filled pillow.
