Compound in banaba shows promise against human rhinoviruses

Human rhinoviruses are the predominant cause of common viral respiratory tract infections. They exhibit symptoms such as sore throat, rhinitis, nasal congestion and cough, as well as acute otitis media and sinusitis, and are associated with exacerbations of asthma in both children and adults

The leaves of Lagerstroemia speciosa L. (banaba in Philippines' Tagalog dialect) are used as traditional medicinal foods in Southeast Asia including in Philippines, Vietnam, Malaysia and southern China. For example, tea brewed with its leaves is often used to treat diabetes.

This recent laboratory study found the compound from banaba was more effective against several strains than the anti-viral drug ribavirin.
