Da Huang Tincture & Alcohol-Free Extract

Da Huang (Rheum palmatum), the Chinese or turkey rhubarb, is a massive perennial of the knotweed family, Polygonaceae, native to the mountains of Gansu, Qinghai, Sichuan, and Tibet at 2,000 to 4,000 meters, and grown there as a crop. From a thick crown it produces huge, deeply palmately lobed leaves up to 60 centimeters across on stout reddish stalks, and in summer sends up a hollow flowering stem 1.5 to 2 meters tall topped with a dense panicle of tiny greenish-white to red flowers. The rhizome and root are heavy and yellow-brown, marbled orange and white when cut, bitter and astringent. We extract the dried rhizome and root.
