Overview
Burdock is a biennial plant with large leaves and prickly burrs that stick to clothing (the inspiration for Velcro). The long, brown root is used as both food (gobo in Japanese cuisine) and medicine. In traditional herbalism, burdock is considered a "alterative" or "blood purifier" - meaning it gradually restores proper function to the body, especially the skin, liver, and lymphatic system.
