A study of Ledum L. genus plants, including those growing in the tundra, in the Far North, may be of interest in expanding the Russian medicinal plant raw material base to design new medications. The component composition of the essential oil of marsh tea (Ledum decumbens) growing in 5 districts of the Yamalo-Nenets Autonomous Okrug was investigated. Gas liquid chromatography could identify 12 components, among which there was a preponderance of citronellol (52% of the total amount of components), geraniol (30% of the total amount of components) and limonen (64% of the total amount of components); neral alcohol (6.00% of the total amount of components) was identified in one sample. Other components of the essential oil were present in virtually equal amounts in all samples. The level of ledol in the essential oil was in the range of 0.033–0.23%, which is inferior to its contents in samples from Yakutia (0.76%) and other regions of Siberia and the Far East (1.3–4.5%). This offers the challenges of using marsh tea as an antitussive drug.
