While the herb is sometimes called Siberian Ginseng, it is not actually a ginseng.
During the 1950’s and 1960’s Russian scientists began to extensively study the constituents and activities of eleuthero. A new terminology was about to be born, as scientists studied substances that were able to bring about an “increased nonspecific resistance” to an organism. These substances and the plants that contained them were called “adaptogens".
Numerous clinical studies performed in Russia have documented the efficacy of eleuthero as an adaptogen. In the late 1960’s and 1970’s studies were conducted in over 2,100 healthy people. These studies showed that eleuthero increased the ability of the subjects to with stand stresses such as heat, noise, motion, exercise, and increase in workload. Subjects also experienced increases in mental alertness and work output.
