Overview InformationBanaba is a species of crepe myrtle tree that is native to the Philippines and Southeast Asia. People use the leaves to make medicine.
Banaba is used for diabetes and weight loss.
How does it work?Banaba seems to lower blood glucose in people with type 2 diabetes, according to very early research. It might help the body use insulin more efficiently.
Uses & Effectiveness
Insufficient Evidence for
- Diabetes. Some early research suggests that taking a particular banaba extract (Glucosol) for 2 weeks lowers blood sugar by 10% in people with type 2 diabetes. However, other early research suggests that taking a single dose of corosolic acid, a chemical in banaba, before eating does not improve post-meal sugar tolerance.
- Weight loss.
- Other conditions.
Side Effects & SafetyBanaba is POSSIBLY SAFE for most people when taken by mouth on a short-term basis. Not enough is known about the safety of using banaba long term.
Special Precautions & Warnings:Pregnancy and breast-feeding: Not enough is known about the use of banaba during pregnancy and breast-feeding. Stay on the safe side and avoid use.
Diabetes: Banaba can affect blood sugar control, so people with diabetes should monitor their blood glucose levels closely. If you have diabetes, it's best to check with your healthcare provider before starting banaba.
Low blood pressure. Banaba might lower blood pressure. In theory, taking banaba might make blood pressure become too low in people with low blood pressure.
Surgery: Banaba might affect blood sugar levels and could make blood sugar control more difficult during and after surgery. Stop using banaba at least 2 weeks before a scheduled surgery.
Be cautious with this combination
Medications for diabetes (Antidiabetes drugs) interacts with BANABA
Banaba might decrease blood sugar. Diabetes medications are also used to lower blood sugar. Taking banaba 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.<br/><br/> 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 following doses have been studied in scientific research:
- For diabetes: A specific banaba extract has been taken at a dose of 32-48 mg per day for 2 weeks. A specific product containing a combination of banaba and cinnamon inner bark has been taken at a dose of 100 mg per day for 12 weeks.
