Although Eleuthero is also known as Siberian Ginseng, it is not a true Panax ginseng - although it does belong to the same botanical family of Araliaceae. The herb has undergone numerous studies showing its remarkable ability to increase one’s capacity to withstand stress. By increasing the uptake of oxygen to the muscles, Eleuthero increases athletic performance. Studies have also shown heightened mental acutity with its use. The plant contains polysaccharides which help to boost immune function and increase resistance to illness. This herb has been found to be quite useful in cases of chronic fatigue, debilitation and stress.
