Siberian Ginseng (Eleutherococcus senticosus) is a very old remedy for erectile dysfunction in traditional Chinese medicine. There was a compelling belief in ancient times that the potency behind the ginseng root stems from its likeness to the human body. The word ginseng is derived from the Chinese term rénshēn which translates to “man root.” The root has a characteristic forked shape, resembling the legs of a man. It was said that the closer the likeness of a root to the human body, the more powerful the root when ingested. Now this doesn’t help us much in the 21st Century regarding the effectiveness of Siberian Ginseng for boosting testosterone – so what does the clinical research have to say?
Treatment assertions regarding Ginseng are many – but the prevailing determinant for testosterone benefits are that ginseng supports overall health and vitality and improves the immune system by directing the body’s strength to areas that need healing. It has been used as an ‘adaptogen’. This term is used by herbalists to describe herbs which increase the body’s resistance to stress
