What is Douglas fir extract dihydroquercetin powder?
Douglas Fir Extract(DFE), also known as dihydroquercetin powder(DHQ),is a bioflavonoid essence (belonging to vitamin P) extracted from the root of larch in the alpine zone. DFE is an important natural antioxidant necessary for the human body. DFE is a rare and extremely valuable pharmaceutical and health food ingredient in the world.
At present, dihydroquercetin is only found in yew, yellow fir, and larch, and there is also a very small amount in the mother tree and wild black cherry. Because yew and Douglas have been listed as endangered tree species in the world, logging is prohibited, while larch is only distributed in the eastern Siberia of Russian northeastern Mongolia, northeastern China, and North Korea, and has a long growth cycle, so the resources available for production are extremely large.

Because dihydroquercetin has a special molecular structure of five phenolic hydroxyl groups, it is the best and most natural and powerful antioxidant found in the world so far, which can effectively remove free radicals and toxins in the human body. Therefore, Siberian Larch extract Dihydroquercetin powder has broad-spectrum biological and pharmacological activities such as anti-inflammatory, antibacterial, anti-radiation, anti-cancer, anti-virus, regulating immunity, clearing melanin, improving microcirculation, etc. It is a precious raw material for the production of food, medicine, and health care products.
