Botanical Profile
Eleutherococcus senticosus is a thorny shrub of the Araliaceae from Northeast Asia. From a raw-material perspective, root and rhizome are the principal materials and must be clearly distinguished from other Araliaceae raw materials such as Panax species.
Eleutherococcus senticosus is a deciduous, heavily armed shrub with thorny shoots, long-stalked palmately divided leaves and small flowers arranged in umbels. The species occurs in cool forest regions of Northeast Asia, including Siberia, northern China, Korea and Japan. The plant forms a branched underground root and rhizome system that constitutes the central raw material. The fruits are small, dark berries. Botanically, the species belongs to the Araliaceae but is not equivalent to Panax ginseng; their constituent profiles and raw-material traditions differ markedly.
Phytochemistry
Root and rhizome contain phenolic, lignan-like, coumarin-like and glycosidic constituents. Eleutherosides are described as analytically significant markers, including eleutheroside B, eleutheroside E and related compounds. Syringin, lignan derivatives, phenylpropanoids, polysaccharides, triterpenes, sterols and other accompanying constituents also occur. Composition varies according to origin, plant part, harvest time, drying and extraction solvent. Hydroalcoholic extracts differ from aqueous preparations and powders.
Traditional Uses
Siberian ginseng root has a modern history of use shaped primarily by Russian and Soviet research and was studied intensively as a botanical raw material in the second half of the twentieth century. In East Asian regions, the plant was also known as a regional root raw material. Use relates primarily to root and rhizome preparations. Historical and traditional information must be distinguished from modern claims concerning performance, stress or immune function.
Current Research
Research addresses eleutherosides, polysaccharides, lignan fractions, adaptogen concepts, cell and animal models, extract standardisation and quality control. Studies investigate different extract types, dosages and starting materials, which makes comparability difficult. Phytochemical work focuses on marker substances, chromatographic profiles and differentiation from other Araliaceae. Clinical data are limited and heterogeneous depending on the research question and preparation.
