What is Yellow dock?
Yellow dock is a plant in the family Polygonaceae, native to Europe and western Asia. It is also known as curly dock, named for the shape of its leaves, and as sour dock because of its bitter taste. The mature plant is a reddish brown colour, and produces a stalk that grows to about 1 m high. It has smooth leaves shooting off from a large basal rosette, with distinctive waved or curled edges. On the stalk flowers and seeds are produced in clusters on branched stems, with the largest cluster being found at the apex.
The roots are 8 to 12 inches long, about 1/2 inch thick, fleshy and usually not forked. Externally they are of a rusty brown and internally whitish, with fine, straight, medullary rays and a rather thick bark. It has little or no smell and a rather bitter taste. The stem is 1 to 3 feet high and branched, the leaves, 6 to 10 inches long. Yellow dock contains relatively small amounts of anthraquinone glycosides, which may contribute to its mild laxative effect. In ancient times, the Chinese and Romans used yellow dock as a digestive aid and for skin conditions. Today it can be found in many forms, and is still used for skin conditions, as a mild laxative, and for liver conditions.
