Rhodiola rosea, indigenous to the polar arctic regions of eastern Siberia, has been shown on healthy men and women to have positive effects on the nervous system and to support normal moods. Widely used in Russia, Rhodiola rosea extract is known for its adaptogenic activity, which increases the body's resistance to stress. Rhodiola rosea leads to an increase in the amount of basic b-endorphin in the blood plasma which inhibits the hormonal changes indicative of stress. 

Cardio protective Benefits of Rhodiola rosea - Eksp Klin Farmakologie 1994
In a Russian study, an extract of Rhodiola rosea was examined for its effects on the pattern of stress-induced cardiac damage which was measured by enzyme accumulation in the heart. Rhodiola rosea was found to help prevent stress induced cardiac damage. Simultaneously, the extract was determined to help prevent both stress induced release of proteins and higher enzyme levels, which can ultimately damage heart tissue. The findings suggest antistressor and cardio protective benefits of Rhodiola rosea without harmful effects on the heart.
