This study evaluates the quality of tarragon essential oil, toxic metals content, and the growth potential of tarragon on heavy metal-contaminated soils. Tarragon demonstrated tolerance to toxic metals and can be cultivated on highly polluted soils. The levels of toxic metals in tarragon essential oil were below the Maximum Permissible Concentrations. Based on translocation and bioconcentration coefficients, tarragon is a Cd, Pb, Zn and Hg excluder and suitable for phytostabilization. Tarragon essential oil exhibits a mixed sabinene/elemicin/isoelemicin/methyleugenol chemotype and could be used in the pharmaceutical, cosmetic, and related industries.
