In Western Herbalism, practitioners have commonly used herbs like passionflower, chamomile, hops and catnip to help people relax. Based off that traditional use, the herbalists formulated the organic Nighty Night tea blend, one of the original best-selling teas since the start of the company in 1974. This tea puts passionflower in the spotlight as the chief active ingredient. Also known as maypop, this exotically flowered vine is traditionally used in Herbal Medicine to help relieve restlessness and/or nervousness, and can be a useful sleep aid during times of mental stress.
