Arctium, commonly known as burdock, is a genus of biennial plants in the Asteraceae family. It is characterized by its large leaves and purple flowers, which bloom in late summer. The plant is native to Europe and Asia but has spread to North America, where it often grows in disturbed areas. Burdock is known for its edible roots, which are used in various cuisines, particularly in Japanese cooking, where it is called "gobo." The roots are rich in dietary fiber and contain antioxidants, making them a popular choice for health-conscious individuals.
