Why People Use Yellow Dock
Yellow dock has been used traditionally as an "alterative" herb, a herb that has general tonic effects. Yellow dock specifically helps the digestive tract, liver, and skin. One of its primary uses is for skin conditions caused by poor digestion, poor liver function, or toxic accumulations.
Yellow dock has a mild laxative effect, due to constituents called anthraquinone glycosides. It stimulates bile and digestive enzymes.
