Overview
Greater burdock is a large biennial herb with enormous leaves and burr-like seed heads that inspired the invention of Velcro. Its long taproot (called "gobo" in Japanese cuisine) is both a nutritious food and a powerful medicinal herb. Burdock root is one of the most important blood-purifying herbs in both Western and Eastern herbal traditions, supporting liver detoxification, skin health, and digestive wellness. It is a key ingredient in the traditional Essiac cancer support formula.
Traditional Use
Burdock has been used medicinally in Europe and Asia for over 3,000 years. In traditional Chinese medicine, burdock seeds (Niubangzi) are used to clear heat, detoxify, and treat throat infections and skin conditions. In European folk medicine, burdock root was a primary "blood purifier" used for skin diseases, arthritis, and liver complaints. Native American tribes used burdock for skin conditions and as a food source. In Japan, burdock root (gobo) is a staple vegetable. The 19th-century Eclectic physicians used burdock extensively for chronic skin conditions and as a lymphatic tonic.
