On Tibetan plateau, the high altitude area rise some 13,000 feet (4 kilometers) above sea level, where travelers to the high plateaus possibly suffer acute hypoxia, a condition created by a diminished supply of oxygen to body tissues. At high altitudes, the air is much thinner than at sea level. In consequence, a person inhales fewer oxygen molecules with each breath. Symptoms of hypoxia, sometimes known as mountain sickness, include headaches, vomiting, sleeplessness, impaired thinking, and an inability to sustain long periods of physical activity.
How residents survive in such harsh environment? In Tibetan plateau, there is a kind of perennial plant called Rhodiola rosea. Growing in cold, oxygen deficit, drought environment with diurnal temperature variation and strong UV radiation, Rhodiola has tenacious vitality. It was therefore praised in ancient medical books as “immortal grass” or “Nine dead resurrection grass.” Rhodiola rosea contains multiple functional components including hydrophilic and hydrophobic ingredients. Most extraction skills, however, can get only hydrophilic ingredients like gallic acid, salidroside, and tyrosol. The hydrophobic ingredients of Rhodiola, like polyphenol or flavonoids were scarcely being extracted and make it a waste.
Salidroside and Tyrosol are specific nutrients from Rhodiola and key elements that allow Rhodiola to survive in cruel environment. Keeping on taking the nutrients are good for modern people with suboptimal health.
In Dalong, the polyphenols extracted from Rhodiola are much more than Rhodiola on the market. Polyphenols help maintain health, young, and beautiful.
In biosphere, propolis contains highest amount of flavonoids and Rhodiola also contains flavonoids. It was proved that flavonoids can regulate physical function and promote metabolism.
