Product Description
What IS Douglas Fir Extract？
Douglas Fir Extract(DFE), also known as dihydroquercetin(DHQ), is a bioketone essence (belonging to vitamin P) extracted from the roots of larch (especially Douglas fir) in the alpine zone, and is an essential natural antioxidant for the human body. Because Douglas fir grows at high altitudes and in cold, middle-aged areas, and has a long growth cycle, its resources are very scarce. At present, Douglas fir is only found in yew, yellow fir, larch, and only a small amount in the mother tree and wild black cherry. While yew and yellow cedar have been listed as endangered species in the world and prohibited from logging, larch is only distributed in eastern Siberia, Russia, northeast Mongolia, northeast China and North Korea, and the growth cycle is longer, so the resources available for the production of dihydroquercetin are more scarce. Global annual production is less than 20 tons.
Due to the special molecular structure of five phenolic hydroxyl groups, Douglas Fir Extract is the best and scarcest natural powerful antioxidant found in the world so far, which can effectively remove free radicals and toxins in the human body. Therefore, it has a wide spectrum of biological and pharmacological activities such as anti-inflammatory, antibacterial, anti-radiation, anti-cancer, anti-viral, regulating immunity, clearing melanin, improving microcirculation, etc. It is a precious raw material for the production of food, drugs and health products.
