Rhubarb root is commonly called Turkish rhubarb. Its scientifc name is Rheum palmatum. Rhubarb is extensively used in traditional Chinese medicine.The root is used as an anticholesterolemic, antiseptic, antispasmodic, antitumor, aperient, astringent, cholagogue, demulcent, diuretic, laxative, purgative, stomachic and tonic. Rhubarb is used primarily for digestive complaints including constipation, diarrhea, heartburn, stomach pain, gastrointestinal (GI) bleeding, and preparation for certain GI diagnostic procedures. Some people use rhubarb so they have to strain less during bowel movements; this reduces pain from hemorrhoids or tears in the skin lining the anal canal (anal fissures) and for the treatment of hyperlipidemia and cancer. However, sound clinical evidence for its use is lacking. Rhubarb is sometimes applied to the skin to treat cold sores. In food, rhubarb stems are eaten in pie and other recipes. Rhubarb is also used as a flavoring agent.
