Burdock (Arctium laps) is a wildflower that originated in Europe and Asia and came to America with French and English settlers. This tall, stout plant features large, wedge-shaped leaves and purple flowers that mature into thistle-like fruits. These give off notoriously clingy burrs. The dried roots of the plant has been used for centuries as a blood purifier, to treat skin infections such as boils, to clear up acne and psoriasis, and to promote circulation. The burdock-leaf poultice is excellent for treating gout. Burdock root contains a high concentration of insulin which strengthens the liver, and mucilage, soothes the GI tract. It also possesses antioxidants, antibacterial, and antifungal properties.
