Overview: Burdock root, also known as gobo or "poor-man's potatoes", is an important food in Japan known for its many healing properties. Traditionally, burdock root was used in Europe, India, and China to treat respiratory disorders, abscesses, joint pain, urinary problems, and for detoxification and cleansing. The German Pharmacopoeia lists this herb for treating gastrointestinal complaints, as well as joint and bone conditions. The tea is also considered to be a traditional blood purifier and diuretic. Up to seventy-five percent of the root is made up of complex carbohydrates known as fructo-oligo-saccharides (FOS), including 27-45% inulin. Based on clinical studies, intake of FOS significantly increases beneficial bifidobacteria within the gastrointestinal tract and eliminates bacterial pathogens. The high levels of FOS in burdock root and its water extract also help to maintain healthy blood sugar levels. As a mildly bitter-tasting herb, it increases saliva and bile secretion, which aids digestion and cleanses the liver.
Traditional Use/Benefits/Body Systems: Traditionally used for treating skin conditions like acne, eczema, and psoriasis. Also used in herbal medicine as a diuretic, as a pain reliever for rheumatic complaints, and as an alternative to help remove accumulated waste products via the kidneys, skin, and mucus membranes.
