Sometimes referred to as golden root or arctic root, Rhodiola Rosea is regarded as an adaptogenic herb. This simply means that its actions are nonspecific and do not disrupt normal biological function, yet the overall effect is increased resistance to stress and enhanced vitality and general strength. Rhodiola Rosea grows at high altitudes and originated in Russia. It is now also grown and harvested in Asia and certain parts of Europe.

Depression

In studies conducted on laboratory animals, Rhodiola Rosea extract appeared to enhance the production of serotonin precursors in the brain, including tryptophan, and 5-hydroxytryptophan. Extensive research has been conducted on serotonin, including how it regulates behavior, pain perception, appetite, temperature regulation, and smooth muscle contraction. When balanced, it results in a sense of mental well-being and contentment, but too little or too much can cause depression, insomnia, or anxiety. Rhodiola Rosea is believed to regulate these substances in the human brain, and ultimately prevent depression.

Enhanced Memory

Studies involving proofreading tests have shown that Rhodiola Rosea enhances concentration and memorization ability over prolonged periods. The herb is also believed to increase the brain's bioelectrical activity, thus improving brain energy and memory.

In a randomized study conducted in 2012 on 40 students, general well-being, mental performance, psychomotor function, and physical fitness were all enhanced in the group given Rhodiola Rosea as opposed to the placebo group. The average scores of the group that received the placebo and the group that received the herb were 3.20 and 3.50, respectively.

Muscle Recovery

Studies show that Rhodiola Rosea can support shorter recovery time after extended workouts, according to studies completed on male athletes. This is likely due to an increase in RNA enzyme levels, which play a key role in muscle recovery following exhaustive exercise.

Immune System Benefits

Rhodiola Rosea also protects and stimulates the immune system by supporting metabolic balance. It has been shown to increase NK cells in the spleen and stomach, which are responsible for seeking out and destroying abnormal cells before they multiply. It is believed that this action may stem from the herb's ability to normalize hormones by stabilizing the release of glucocorticoids in the bloodstream.

Additional Considerations

The medicinal benefits of Rhodiola Rosea are found in its roots, and the harvesting and manufacturing process is somewhat lengthy. Plants are harvested approximately every five years, and the roots ground and boiled at high temperatures to create the extract that is eventually manufactured in powdered form and taken as capsules.
