Ginseng has been used medicinally in Eastern Asia for over 200 years to promote health and longevity. Ginseng works by assisting the body to adapt to physical and emotional stress. This is done primarily by promoting healthy levels of cortisol. Ginseng also promotes memory and learning, immune function, and cardiovascular health.
