Banaba is the leaf of Lagerstroemia speciosa, a flowering tree native to South and Southeast Asia. In India it is called jarul or "Pride of India" and is often planted along roads for its large purple flowers. The name banaba comes from the Philippines, where the leaves are traditionally brewed as tea.
What is corosolic acid?
Banaba leaves naturally contain corosolic acid, a plant compound. Many banaba extracts are standardised to a stated percentage of corosolic acid, commonly 1% or more.
Leaf powder vs extract
A plain leaf powder has no guaranteed corosolic acid content, while a standardised extract does. Check which the label lists and the amount per serving.
What to check before you buy
- The amount of each ingredient per serving, not just per capsule
- How many capsules make one serving and how many servings are in the pack
- Whether any ingredient sits inside an undisclosed "proprietary blend"
- The veg/non-veg mark and the manufacturer details on the pack
