The blue vervain or verbena is a creeping perennial of the mint family, growing close to ground and bearing numerous, small lilac-blue flowers. The term vervain comes from the Celtic ferfaen, from fer (to drive away) and faen (a stone), referring to the plantÍs historical use in treating kidney stones.
The above-ground parts of the plant gathered before flowering, dried.
Traditionally used as a tea, sometimes available in tea bags; also used in herbal teas. Traditional herbal medicines use equal amounts of vervain and sugar. May also be taken as an extract.
Blue vervain is a diuretic used to treat bladder infections, an analgesic tea for hemorrhoid sufferers (usually drunk but also useful as a wash), an expectorant used to treat chronic bronchitis, and an antirheumatic used to relive joint pain.
