BLUEBERRY Overview Information
Blueberry is a plant. People use the fruit and leaves to make medicine.
Be careful not to confuse blueberry with bilberry. Outside of the United States, the name “blueberry” may be used for a plant called “bilberry” in the U.S.
Blueberry is used for preventing cataracts and glaucoma and for treating ulcers, urinary tract infections (UTIs), multiple sclerosis (MS), chronic fatigue syndrome (CFS), colic, fever, varicose veins, and hemorrhoids. Blueberry is also used for improving circulation, and as a laxative.
Some women use blueberry for labor pains and as a tonic after miscarriage.
The dried fruit and leaves are used for diarrhea.
Tea made from the dried leaves is used for sore throat and swelling (inflammation) of the mouth or the skin lining the throat.
Health providers have used blueberry juice as a contrast agent in magnetic resonance imaging (MRI). Contrast agents make it possible for radiologists to see and interpret the images.
Some people inhale the fumes of burning dried blueberry flowers for treatment of insanity.
How does it work?
Blueberry, like its relative the cranberry, might help prevent bladder infections by stopping bacteria from attaching to the walls of the bladder. Blueberry fruit is high in fiber which could help normal digestive function. It also contains vitamin C and other antioxidants.
- Diabetes. Early research suggests that taking a specific product containing blueberry leaf extract (Blueberin) three times daily for 4 weeks can lower blood sugar levels in people with type 2 diabetes. Also, taking a combination of blueberry and sea buckthorn appears to lower levels of hemoglobin A1c, a measurement of average blood sugar levels, in children with type 1 diabetes.
