Other Proposed Uses

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. Historically, the plant has been used to treat a variety of problems, including constipation and diarrhea, as well as dermatitis and venereal diseases. 1 Powdered yellow dock root has also been used as a mouthwash or dentifrice.

What Is Yellow Dock Used for Today?

Yellow dock root has no established medical uses. However, it contains chemicals called anthroquinones (also found in the more famous herbal laxative senna), 2 which stimulate bowel movements. For this reason, yellow dock is occasionally included in herbal laxative mixtures. 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.


Typical doses of yellow dock root are 2 to 4 g of the dried root, 2 to 4 ml of the liquid extract, or 1 to 2 ml of the tincture. 3
