This wild herb has been used for centuries in China as a sleep aid, helping to combat anxiety and assist with easing depression. In addition to being a nerve tonic, it's also caffeine-free (but high in L-Theanine) making it the perfect tea to enjoy in the evenings or any other time when seeking a tranquil state of mind.
