What eleuthero is
Eleuthero is a thorny shrub native to northeast Asia. Despite its nickname, it is not a true ginseng (Panax). It became famous in the Soviet Union, where it was studied for endurance and resilience.
The research
In a 2010 study in the Chinese Journal of Physiology, healthy adults took eleuthero for eight weeks. Researchers reported improved endurance capacity, better cardiovascular function and a shift toward using fat for fuel, sparing glycogen. Adaptogens in general are reviewed by Panossian and Wikman.
