Senna is the most common ingredient in natural laxative teas. Other ingredients include barley, licorice root, rhubarb root and dandelion root. Laxative teas are used for medicinal reasons or for weight loss.
Senna pods and leaves work as natural purgatives on the bowel. People should not use tea with senna for longer than a week or if they are pregnant. Barley is a natural source of soluble fiber. Licorice root reduces inflammation and gas production in the bowels. Rhubarb root helps the bowels function better by stimulating the digestive system and working as an astringent. Dandelion root works as a diuretic and natural detoxifier. Common commercial laxative tea brands include Gaia and Traditional Medicinals.
