What banaba is
Banaba, or giant crape myrtle, is a flowering tree from the Philippines, India and Southeast Asia. Its leaves are traditionally brewed into tea.
Corosolic acid
The leaf is a natural source of corosolic acid. A review in Phytotherapy Research summarized human and lab studies on banaba and corosolic acid, describing effects on glucose and noting no serious adverse effects in the studies reviewed (PubMed).

Banaba supports the “balance” step of MetaGlucent’s design, next to cinnamon. Together with berberine, chromium, gymnema and bitter melon it covers several angles of glucose metabolism. See how MetaGlucent works.
Banaba with chromium
Researchers have also looked at banaba alongside chromium picolinate for prediabetes, reflecting a broader trend toward combining complementary ingredients rather than relying on one. MetaGlucent follows the same logic by pairing banaba with chromium, berberine and three other botanicals. See chromium picolinate and how MetaGlucent works.
Safety
Banaba was well tolerated in studies. As with any glucose-supporting herb, people on diabetes medicine should talk to their doctor (NCCIH).
