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 it works
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.
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.
Banaba is POSSIBLY SAFE for most people when taken by mouth on a short-term basis. The long-term safety is unknown.
Pregnancy and breast-feeding: Not enough is known about the use of banaba duringpregnancyandbreast-feeding. Stay on the safe side and avoid use.Are there any interactions with medications?
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.
ModerateMedications for high blood pressure (Antihypertensive drugs)
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.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.Banaba might decrease blood pressure. Taking banaba along with medications used for lowering high blood pressure might cause your blood pressure to go too low. Do not take too much banaba if you are taking medications for high blood pressure. Some medications for high blood pressure include nifedipine (Adalat, Procardia), verapamil (Calan, Isoptin, Verelan), diltiazem (Cardizem), isradipine (DynaCirc), felodipine (Plendil), amlodipine (Norvasc), and others.Medications moved by pumps in cells (Organic Anion-Transporting Polypeptide Substrates)
Some medications are moved by pumps in cells. Banaba might change how these pumps work and decrease how much of some medications get absorbed by the body. This could make these medications less effective. Some of these medications that are moved by pumps in cells include bosentan (Tracleer), celiprolol (Celicard, others), etoposide (VePesid), fexofenadine (Allegra), fluoroquinolone antibiotics, glyburide (Micronase, Diabeta), irinotecan (Camptosar), methotrexate, nadolol (Corgard), paclitaxel (Taxol), saquinavir (Fortovase, Invirase), rifampin, statins, talinolol, torsemide (Demadex), troglitazone, and valsartan (Diovan).
