Turkey Rhubarb Root Powder (1 lb)

What the brand says

Turkey rhubarb is an Asian relative of the spring vegetable most Americans are familiar with. As some of its common names imply, this larger variety is native to China, where it has been used for centuries. Turkey rhubarb is also widely cultivated elsewhere for its root, which contains a number of tannins, flavonoids and anthraquinone compounds, including aloe-emodin. Decorative Usages - The wood-like pieces of root lend a rustic appeal to herbal displays.
