| "French and Russian tarragon, Artemisia dracunculus L., leaves have glandular hairs distributed over the whole surface and secretory cavities arranged in files along the major veins in the mesophyll. Chemical composition analysis of leaves, leaf epidermis, and leaf mesophyll by hydrodistillation and solvent extraction indicate quantitative differences in composition between the epidermis and the mesophyll. The main components in the essential oils, methyl chavicol in French tarragon and elemicin and methyl eugenol in the Russian tarragon, were observed to accumulate primarily in the mesophyll." \\ | "French and Russian tarragon, Artemisia dracunculus L., leaves have glandular hairs distributed over the whole surface and secretory cavities arranged in files along the major veins in the mesophyll.

| "Artemisia dracunculus L. (tarragon) has a long history of use as a spice and remedy. Two well-described “cultivars” (Russian and French) are used widely and differ in ploidy level, morphology, and chemistry. Key biologically active secondary metabolites are essential oils (0.15-3.1%), coumarins (>1%), flavonoids, and phenolcarbonic acids. In vivo studies mainly in rodents, particularly from Russian sources, highlight potential anti-inflammatory, hepatoprotective, and antihyperglycemic effects. Despite concerns about the toxic effects of two of its main constituents, estragole (up to 82%) and methyleugenol (up to 39%), no acute toxicity or mutagenic activity has been reported at doses relevant for human consumption.
