Yellow dock (Rumex crispus) is a perennial herb with a long history of use in traditional Western herbalism, particularly valued for its root. Research suggests that yellow dock root contains anthraquinone glycosides, which may gently support digestive regularity and help ease occasional constipation by stimulating bowel activity. Studies indicate the plant is also rich in tannins and naturally occurring minerals, including iron, which has led to its traditional use in supporting nutrient absorption and overall digestive health. Preliminary research points to potential benefits for liver function, as the root may help promote healthy bile production, and its historical use for skin conditions has drawn interest from researchers exploring its astringent and cleansing properties. While these traditional applications are promising, more rigorous clinical studies are needed to fully understand the scope of yellow dock's benefits.
