Turkey rhubarb is an Asian variety of rhubarb also commonly referred to as Chinese rhubarb, Indian Rhubarb and, in China, as da huang. Like other varieties of rhubarb, the large, leafy greens of the plant are avoided because they contain high levels of oxalic acid. The root, however, which contains several antioxidant compounds, is used to produce liquid tinctures and extracts. The powdered herb is taken in capsule form, or is used to make topical poultices to address minor skin irritations.
