Yellow dock root, also know as Rumex crispus, is an herb widely used by herbalists as a general health tonic. It grows throughout North America and is used in Native American herbal formulas. The leaves and root of the plant are used in tinctures and teas. Yellow dock root can cause allergic reactions. Always consult with your doctor or health-care provider before using any herbal medicines.
Yellow dock root is used to help alleviate stomach acid, heartburn and indigestion, according to the University of Michigan Heath System. It is a bitter herb thought to stimulate the digestive function, helping to increase both digestive enzymes and stomach acid. Yellow dock root is taken in tincture form of ¼ to ½ teaspoon three times per day or used in a tea. The tea can be drunk up to three times per day, before meals.
Yellow dock root is also used for its laxative effects. It contains low levels of anthraquinone glycosides, which stimulates the secretion of water into the intestines, causing a laxative effect. Yellow dock root taken in tea can cause diarrhea or loose stools, which can be helpful for people suffering from constipation.
Yellow dock root has been used as a remedy for skin conditions such as age spots and psoriasis, according to a study by Elizabeth A. Massio and Karam F. A. Soliman published in the March 2009 issue of “Phytotherapy Research.” According to Native American legends, yellow dock root is pulverized into a pulp and used as a salve on psoriasis, freckles, eczema and other skin disorders.
Anemia is a blood condition that causes extreme tiredness and weakness. Yellow dock root combined with alfalfa, dandelion root and burdock is a traditional treatment for mild cases of anemia. It is claimed to fortify and cleanse the blood while strengthening the body, according to the University of Maryland Medical Center. The roots are simmered for 20 minutes in tea. One tablespoon per cup of water is the recommended dosage.
Yellow dock root should only be used under the supervision of your doctor or health care provider. Potential allergic reactions may be severe and include liver and kidney damage. Yellow dock root should not be used if you have kidney stones, caution Massio and Soliman in their research.
