Tarragon (Artemisia dracunculus), also known as estragon, is a species of perennial herb in the sunflower family. It is widespread in the wild across much of Eurasia and North America, and is cultivated for culinary and medicinal purposes.
Distillation of the tarragon herb is accomplished almost exclusively in France, although smaller quantities are produced in Holland, Hungary and the U.S.A. The whole overground part of the herb is steam distilled immediately prior to the inflorescence.
