Banaba leaf, derived from the tree *Lagerstroemia speciosa* and native to Southeast Asia, has a long history of use in traditional medicine, particularly for its purported effects on blood sugar. The primary active compound believed to be responsible for many of its metabolic effects is corosolic acid. Historically, banaba leaf preparations, such as teas and extracts, have been used to assist with conditions related to glucose regulation. In contemporary supplement use, banaba leaf extracts are standardized to contain specific concentrations of corosolic acid. (Examine.com, NIH ODS)
Banaba leaf is categorized as a dietary supplement. It is available in various forms, including capsules, tablets, and liquid extracts. While traditionally used for blood sugar support, research continues to explore its broader implications for metabolic health. The half-life of corosolic acid, its main active component, is approximately 6 hours, suggesting that effects may be sustained over several hours after ingestion. (Examine.com)
