Tarragon

 ( Artemisia ) 

Tarragon ( Artemisia dracunculus), also known as estragon, is a species of perennial herbaceous plant in the family Asteraceae. It is widespread in the wild across much of Eurasia and North America and is cultivated for culinary and medicinal purposes.

One subspecies, Artemisia dracunculus var. sativa, is cultivated to use the leaves as an aromatic culinary herb. In some other subspecies, the characteristic aroma is largely absent. Informal names for distinguishing the variations include "French tarragon" (best for culinary use) and "Russian tarragon".

Tarragon grows to tall, with slender branches. The leaves are lanceolate, long and broad, glossy green, with an entire margin. The flowers are produced in small capitula diameter, each capitulum containing up to 40 yellow or greenish-yellow . French tarragon, however, seldom produces any flowers (or seeds). Some tarragon plants produce seeds that are generally sterile. Others produce viable seeds. Tarragon has rhizomatous roots that it uses to spread and readily reproduce.

Cultivation French tarragon is the variety used for cooking in the kitchen and is not grown from seed, as the flowers are sterile; instead, it is propagated by root division.

Russian tarragon ( A. dracunculoides L.) can be grown from seed but is much weaker in flavor when compared to the French variety.

However, Russian tarragon is a far more hardy and vigorous plant, spreading at the roots and growing over a meter tall. This tarragon actually prefers poor and happily tolerates drought and neglect. It is not as intensely aromatic and flavorsome as its French cousin, but it produces many more leaves from early spring onwards that are mild and good in salads and cooked food. Russian tarragon loses what flavor it has as it ages and is widely considered useless as a culinary herb, though it is sometimes used in crafts. The young stems in early spring can be cooked as an asparagus substitute. recommend that Russian tarragon be grown indoors from seed and planted in summer. The spreading plants can be divided easily.

A better substitute for Russian tarragon is Mexican tarragon ( Tagetes lucida), also known as Mexican mint marigold, Texas tarragon, or winter tarragon.

It is much more reminiscent of French tarragon, with a hint of anise. Although not in the same genus as the other tarragons, Mexican tarragon has a more robust flavor than Russian tarragon that does not diminish significantly with age. It cannot however be grown as a perennial in cold climates.

Health Tarragon has a flavor and odor profile reminiscent of anise due largely to the presence of estragole, a known carcinogen and teratogen in mice. Estragole concentration in fresh tarragon leaves is about 2900 mg/kg. However, a European Union investigation concluded that the danger of estragole is minimal. Research studying rat livers found a BMDL₁₀ (Approximately the dose that would cause a 10% increase in background tumor rate) of estragole to be 3.3–6.5 mg/kg body weight per day, which for an 80 kg human would be ~400 mg per day, or 130 g of fresh tarragon leaves per day. As used as a culinary herb, a typical quantity used in a dish could be 5 g of fresh leaves. Estragole, along with other oils that provide tarragon its flavor, are highly volatile and will vaporise as the leaf is dried, reducing both the health risk and the useability of the herb.

Several other herbs, such as basil, also contain estragole.

Uses

Culinary use In Syria, fresh tarragon is eaten with white Syrian cheese, and also used with dishes such as shish barak and kibbeh labaniyeh.

In Iran and Armenia, tarragon is used as a side dish in sabzi khordan (fresh herbs), or in stews and Iranian cuisine or Armenian cuisine-style Torshi, particularly khiar shoor (pickled cucumbers) and other pickled vegetables, or fruits by extension.

Tarragon is one of the four fines herbes of French cooking and is particularly suitable for chicken, fish, and egg dishes. Tarragon is the main flavoring component of Béarnaise sauce. Fresh, lightly bruised tarragon sprigs are steeped in vinegar to produce tarragon vinegar. Pounded with butter, it produces an excellent topping for grilled salmon or beef.

Tarragon is used to flavor a popular carbonated soft drink in Armenia, Russia, Georgia (where it originally comes from), and, by extension, Ukraine and Kazakhstan. The drink, named Tarkhuna, is made out of sugar, carbonated water, and tarragon leaves which give it its signature green color.

Tarragon is one of the ingredients in Chakapuli, a Georgian dish.

Chemistry Gas chromatography/mass spectrometry analysis has revealed that A. dracunculus oil contains predominantly phenylpropanoids such as methyl chavicol (16.2%), methyl eugenol (35.8%), and anethole (21.1%). The other major constituents were and , including ocimene (20.6%), limonene (12.4%), alpha-Pinene (5.1%), ocimene (4.8%), methyl eugenol (2.2%), beta-Pinene (0.8%), terpinolene (0.5%), bornyl acetate (0.5%) and bicyclogermacrene (0.5%). The organic compound capillin was initially isolated from Artemisia capillaris in 1956.

Cis-Pellitorin, an isobutyramide eliciting a pungent taste, has been isolated from the tarragon plant.Gatfield, I. L.; Ley, J. P.; Foerstner, J.; Krammer, G.; Machinek, A. Production of cis-pellitorin and use as a flavouring. World Patent WO2004000787 A2

Name The plant is commonly known as dragon in Swedish and Dutch. The use of Dragon for the herb or plant in German is outdated. The species name, dracunculus, means "little dragon", and the plant seems to be so named due to its coiled roots. See Artemisia for the genus name derivative.
