Corosolic acid has numerous biological properties, including antidiabetic, anti-inflammatory, antiproliferative, and protein kinase C inhibition activity. However, there is a lack of clinical evidence to support these uses.
Numerous commercial formulations are available, including tablets, capsules, hypoglycemic food products, and cosmetics. Most formulations are available in capsule form, containing 18% corosolic acid and derived from Lagerstroemia speciosa L. Manufacturer suggested dosage is 1 softgel by mouth 30 minutes before morning and evening meals. Softgel products are marketed for noninsulin dependent type 2 diabetic patients.
