Yellow Dock
Parts Used & Where Grown
Yellow dock is found in many places throughout North America. The root of the plant is used in herbal medicine.
How It Works
Yellow dock contains relatively small amounts of anthraquinone glycosides, which may contribute to its mild laxative effect.1 It is also thought to stimulate bile production. It is often used as a digestive bitter for people with poor digestion. No human studies have been done on its use as medicine.
