Rumex crispus can be used as a laxative, to help symptoms of psoriasis, and to treat anemia. Also known as yellow dock root, this plant is used as a health tonic. Rumex crispus naturally grows in North America and the root and leaves are commonly used in teas and tinctures. Although Rumex crispus has been shown to be effective in treating certain medical conditions, patients should discuss its risks and benefits with a healthcare provider before using it.
Rumex crispus may produce a laxative effect because it contains a substance that encourages water to infiltrate the intestines, allowing for improved bowel function. This herb, if consumed in tea form, can contribute to loose stools and diarrhea, which may be a welcome relief for those who experience constipation. It is important to note, however, that excessive diarrhea can cause dehydration, and if excessive or prolonged diarrhea occurs as the result of consuming yellow dock root, the healthcare provider needs to be notified.
Anemia is another medical condition that may be helped by consuming Rumex crispus. People suffering from anemia can experience fatigue, weakness, and dizziness. Treating anemia with a tea made from yellow dock may help improve symptoms and help cleanse the blood. Although anemia is common, especially in children and women who are menstruating, it can sometimes indicate serious medical conditions such as bleeding internally.
Yellow dock is also used to treat skin conditions, such as psoriasis, and may help reduce symptoms like inflammation, scaliness, and redness. In addition, it is sometimes used as a topical preparation and applied to psoriatic skin lesions. Rumex crispus might also be helpful in treating dermatitis, various rashes, and allergic reactions, but severe cases of psoriasis need medical evaluation and treatment. Using Rumex crispus to treat skin disorders is not recommended unless a healthcare provider has deemed it safe.
To alleviate symptoms of heartburn, indigestion, and excessive stomach acid, Rumex crispus can be taken in the form of a tincture or used in tea. The tea can be consumed up to three times daily and it can also be taken up to three times daily when used as a tincture. Yellow dock is a bitter herb, which means it may help improve digestive function. If, however, heartburn and excessive stomach acid persists, or is not relieved by repeated treatment efforts, a condition known as gastroesophageal reflux disease (GERD) may be present and should be evaluated by a healthcare professional for further treatment.
