Herb Tea for Rest Say goodnight to tossing and turning. Steep a pot of our caffeine-free herbal blend and breathe a sigh of sweet relief as the bouquet of rooibos, soothing chamomile, passionflower and the mellowing properties of valerian gently lulls you toward blissful rest*. Valerian wont interfere with REM sleep, so you wont have to contend with the morning hangover that often results from sleep-aids.
