Rhodiola is a perennial herb , also known as Kuye Red Sedum, Alpine Rhodiola, and Xianci Grass. It is derived from the whole grass of Rhodiola rosea L, belongs to the Crassulaceae family. Rhodiola extract contains an almost unlimited amount of phenolic antioxidants and contains Proanthocyanidins—a phytochemical found in grape seed, cinnamon, cocoa, bilberry, cranberry, black currant ,green tea, and black tea. Recent studies show that this phytochemical’s antioxidant capabilities are 20 times more powerful than that of Vitamin C and 50 times more potent than vitamin E. SO Rhodiola extract is a powerful energizing and protective concentrate that results in healthy and radiant skin. It protects cells from free radical aggression and recharges cells with energy. The result is a revitalized, glowing complexion with improved skin tone.
Rhodiola rosea is a plant that lives at high altitude in Europe and Asia, widely used for its high capacity to increase the organism resistance to different stress conditions. It has become a common component of many dietary supplements also in the Western world. A study investigate find that the Rhodiola rosea roots aqueous extract on in vitro human erythrocytes exposed to hypochlorous acid (HOCl)-oxidative stress. The results obtained are consistent with a significant protection of the extract in presence of the oxidative agent, but a cautionary note emerges from the analysis of the data related to the cell exposition to the plant extract in the absence of any induced oxidative stress. In fact, the addition to erythrocyte of high doses of R. rosea extract always determines severe alterations of the cell shape.Rhodiala rosea have ultrastructural and hemolytic behaviour when they are in red blood cell.
However, Rhodiola rose not only has good antioxidant activity in red blood cells, but also has antioxidant protection in high-intensity physical exercise.In physiological conditions, the response to oxidative stress induced by strenuous physical training, is not always efficient. Furthermore, a weak muscle fiber antioxidant system can contribute to muscle wasting during ageing and pathological conditions. Natural antioxidant supplements could counteract the effects of oxidative stress. The herbal supplement Rhodiola rosea aqueous extract was characterized in terms of its polyphenol content and used to test for antioxidant activity against ROS, produced during muscle contraction. thier results showed that Rhodiola rosea extract reduced the oxidative stress produced by muscle contraction and brought values of ROS production back to physiological levels. They suggest that Rhodiola rosea could act a role of protective antioxidant during intense physical exercise.
