Diabetes is a chronic, lifelong condition that affects about 25.8 million Americans, according to the 2011 National Diabetes Fact Sheet. The condition is characterized by high levels of glucose in the blood, and it may occur due to either reduced production of the pancreatic hormone insulin in the body or lower sensitivity of cells to insulin. Symptoms generally include blurry vision, excessive thirst, frequent urination, weight loss and fatigue. Medications along with healthy diet and exercise help manage the condition. Certain herbal supplements, such as yucca, may also benefit diabetics.
What Is Yucca?
Yucca trees and shrubs are characterized by stiff, evergreen, needle-like leaves, a stout trunk and a dense flowerhead. The bitter-tasting saponins found in roots and flowers of the plant are responsible for its medicinal value and have been used traditionally to treat a variety of conditions, including inflammation, infection and cancer. The supplements are available as tablets and capsule. However, clinical trials have been limited, so be sure to consult a doctor to determine a dose and form that is right for you.
Effect of Yucca on Diabetes
Yucca extracts possess significant hypoglycemic and hypolipidemic activity and help lower glucose and cholesterol levels in diabetic animal models, according to a study published in the September-October 2008 issue of the "Journal of Diabetes and Its Complications." The study also reports that yucca extracts are also powerful antioxidants that protect the cells of diabetic animals from the harmful effects of free radicals. Researchers expect similar results in actual clinical cases, although no trials have been conducted to prove these benefits conclusively. Dr. James A. Duke, author of "The Green Pharmacy Herbal Handbook," also points out that Native Americans have used yucca extracts to treat diabetes and to lower blood sugar and cholesterol levels.
Side Effects
There is very little scientific information regarding the side effects and drug interactions associated with yucca products, although the herb may cause allergic reactions in some individuals. Toxic reactions were observed in some laboratory animals, but it is not clear whether humans would experience similar effects.
Precautions
Although you may not need a prescription to obtain yucca supplements, to avoid complications it is best to talk to a doctor before using them. Inform your physician about any preexisting conditions you have and other medications you are taking. Also, the production and supply of yucca supplements are not regulated by the Food and Drug Administration, so be sure to talk to a pharmacist to ensure the safety of the product.
