"Tarragon (Artemisia dracunculus), also known as estragon, is a species of perennial herb in the sunflower family. It is cultivated for culinary and medicinal purposes. Tarragon is one of the four fines herbes of cooking, and is particularly suitable for chicken, fish, and egg dishes. Tarragon is the main flavoring component of Béarnaise sauce. Fresh, lightly bruised sprigs of tarragon are steeped in vinegar to produce tarragon vinegar."
