Siberian Ginseng comes from the woody roots and not the typical fleshy rootstocks of the other ginsengs. The active ingredients, eleuthrerosides (B & E), are glycosides which provide the adaptogenic properties. Siberian Ginseng helps the body handle stressful conditions while enhancing mental and athletic abilities. The glycosides appear to act on the adrenal glands, helping to prevent adrenal hypertrophy and excess corticosteroid production in response to stress. Siberian Ginseng has been shown to increase energy, stamina, help the body resist viral infections, environmental toxins, radiation and chemotherapy. Siberian Ginseng is used to restore memory, concentration and cognitive abilities which may be impaired by improper blood supply to the brain.
