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.
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.
Insufficient Evidence to Rate Effectiveness for...
- 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.
- Preventing cataracts and glaucoma.
- Urinary tract infections (UTIs).
- Multiple sclerosis (MS).
- Chronic fatigue syndrome (CFS).
- Sore throat.
- Varicose veins.
- Bad circulation.
- Labor pains.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Diabetes: Blueberry might lower blood sugar levels in people with diabetes. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use blueberry products. The dose of your diabetes medications may need to be adjusted by your healthcare provider.
Surgery: Blueberry might affect blood glucose levels and could interfere with blood sugar control during and after surgery. Stop using blueberry at least 2 weeks before a scheduled surgery.
Medications for diabetes (Antidiabetes drugs)Interaction Rating: Minor Be cautious with this combination.Talk with your health provider.
Blueberry leaves might decrease blood sugar. Diabetes medications are also used to lower blood sugar. Taking blueberry leaves along with diabetes medications might cause your blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.
Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.
The appropriate dose of blueberry depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for blueberry. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
