This beautiful purple flowered plant is called Blue Vervain, and is a wonderful addition to my herb garden. Blue Vervain (Verbena hastata) has been used by herbalists for centuries in Europe and in the United States. The name Vervain is derived from the Celtic word “ferfain” and was used as a diuretic to treat bladder infections. Other common names are “Herb of Grace” or “American Hyssop.”
Presently Vervain is found in many herbal formulas to treat PMS and menopausal anxiety, since it has a relaxing effect on the nervous system. It also helps to expel mucus from the lungs and relieve coughs and induces a sweat during the early stages of a fever. I have enjoyed watching the bees gathering pollen on the deep purple flowers, that slowly fade to a lavender as the flowers ages.
Do not use Vervain during pregnancy.
