Rheum palmatum is a broadleaf, rhizomatous vegetable also known as da huang, Chinese rhubarb and, in the United States, as wild rhubarb. The plant is naturally distributed throughout China, Tibet and parts of Europe as well.
For centuries, rhubarb root has held a prominent place in Chinese herbalism and is featured in many classic formulas today. At one time, the herb was a major item of trade along the Silk Road. Once China embraced free trade with the west, the root took on other common names that reference specific trade routes, such as Indian rhubarb, Turkey rhubarb and Russian rhubarb.
The potent astringent qualities of rhubarb root is owing to the roots tannin content. The herb also contains a number of anthranoid derivatives, most notably emodin and aloe-emedin.
