Overview Information

Banaba 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 preliminary 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.
More evidence is needed to rate the effectiveness of banaba for these uses.

Side Effects

Side Effects & Safety

Banaba is POSSIBLY SAFE for most people when taken by mouth on a short-term basis. The long-term safety is unknown.

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.



Moderate Interaction

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 appropriate dose of banaba 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 banaba. 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.
