Chinese Yam (Dioscorea polystachya)

Dioscorea polystachya, commonly known as Chinese yam or cinnamon vine, is a perennial climbing vine in the Dioscoreaceae family. Native to China and East Asia, it is cultivated for its starchy tubers, which are consumed as a food staple, in traditional dishes, and for medicinal purposes. Traditionally, various parts of the plant—including tubers, leaves, and stems—have been used in folk medicine for their digestive, tonic, and immune-supporting properties. With its culinary, medicinal, and cultural significance, Dioscorea polystachya remains an important species in East Asian agriculture and herbal traditions.
