Fagopyrum tataricum, also known as Tartary buckwheat, green buckwheat, ku qiao, or bitter buckwheat, is a domesticated food plant in the genus Fagopyrum in the family Polygonaceae. With another species in the same genus, common buckwheat, it is often counted as a cereal, but unlike the true cereals the buckwheats are not members of the grass family. Thus, they are not related to true wheat. Tartary buckwheat is more bitter and contains more rutin than common buckwheat. It also contains quercitrin. Rutin and quercitrin have been proven effective in detoxification, especially in prevention of liver damage or liver inflammatory injury.
Tartar buckwheat was domesticated in east Asia and is also cultivated in Europe and North America. While it is an unfamiliar food in the West, it is common in the Himalayan region today, as well as other regions in Southwest China such as Sichuan province.
