Yellow dock ( Rumex crispus ) is a perennial flowering herb, native to Europe, which grows throughout the United States. Its yellow roots were traditionally thought to have medicinal properties, and its sour-sweet leaves can be used (in moderation) as a salad green.
What Is Yellow Dock Used for Today?
Like many other plants, yellow dock contains a substantial amount of tannins. These have astringent properties that may offer some benefit for treating minor skin wounds and hemorrhoids . Yellow dock is also sometimes recommended for nasal and lung congestion.
Comprehensive safety studies of yellow dock have not been performed, and for this reason it should not be used by pregnant or nursing women, young children, or individuals with severe liver or kidney disease.
