Another remarkable effect of the use of banaba leaf is its ability to help lower blood glucose levels in people with diabetes. Investigation from the Suzuka University in Japan found that the leaf was able to improve glucose uptake in both test tube and animal studies, providing a significant improvement in blood sugar levels. Results recommend banaba leaf could be of help as an adjunct treatment for diabetes. Compounds such as corosolic acid and tannins appear to be the components with anti-hyperglycemic effects. (1)

(3)

The use of banaba leaf as a medicinal compound has included its service as a natural remedy for relieving viral infections. About half of the cases of the common cold are caused by viral agents that attack the respiratory system, causing symptoms of severe rhinitis. Research has discovered that ellagic acid, one of the active components of banaba leaf, was found to be effective against three common viral agents involved in the occurrence of rhinitis symptoms. Banaba leaf’s anti-viral properties are being studied at as an assistant treatment for HIV infection, to improve patients’ ability to fight the disease. (4)
5. Bacterial Infections
Banaba leaf has also been used traditionally as an anti-infective agent and for lowering fever caused by infections. A study from the University of the Philippines investigated banaba leaf for use against some common infectious agents and found that it was highly effective for reducing these infections, with results occasionally similar to pharmaceutical antibiotics. (5)

Researchers at Mukogawa Women’s University in Nishinomiya, Japan found that by the end of 10 weeks of treatment with banaba leaf, blood pressure had been dropped, fat metabolism had normalized, and the body’s inflammation levels had decreased.
7. Natural Antioxidant
Leaves consist of the minerals manganese and zinc. Extracts from the seeds have been found to have powerful antioxidant properties and are in fact being investigated as a possible HIV treatment.

Banaba plays an important role in the fight against cervical cancer.

Banaba is considered a very safe and effective natural treatment remedy for gout. For centuries, Filipinos have boiled the leaves and used them to treat gout. Leaves consist of valoneic acid dilactone or VAD, which is extremely effective in preventing the xanthine oxidase enzyme from producing uric acid. High amounts of uric acid in the body crystallize and cause devastating pain and inflammation. Reducing the amount of excess uric acid in the body prevents the formation of gout. Popular uric acid management supplement, such as Urcinol, also consists of Banaba.

Generally, pain-relievers and heat are used to relieve symptoms of pain, cramping and inability produce adequate amounts of urine to flush out bacteria from the urinary tract. In severe cases, several different types of antibiotics are used to remove the infections. Banaba leaf also has traditional use for urinary tract infections and kidney problems. The anti-inflammatory properties of the components are supposed to have a soothing effect on urinary tract tissues, while anti-bacterial effects remove the infectious agents. Banaba leaf was traditionally soaked into a tea to relieve symptoms of UTI.
