American Blue Vervain (Verbena hastata) is a premier, highly active nervine and diaphoretic herb containing iridoid glycosides (hastatoside and verbenalin), volatile essential oils, and bitter principles. It acts as an intense nervous system sedative and muscle relaxant, quickly easing severe neck and shoulder tension caused by chronic stress or burnout. It also acts as an effective diaphoretic to promote sweating and cool down fevers.
