A plant-derived chemical from a South American tree shows promise in protecting eye cells from oxygen-starvation damage, hinting it might help with brain injuries too.
Scientific Claim
Brosimine B, a flavonoid isolated from Brosimum acutifolium bark, demonstrates neuroprotective associations in avian retinal cell cultures under oxidative stress, supporting its potential as a candidate for further investigation in ischemic retinal and CNS injury models.
Original Statement
“These results confirm that Brosimine B exhibits hormetic neuroprotective effects within a well-defined concentration window, supporting its potential as a therapeutic agent for oxidative stress–related retinal damage.”

Brosimine B and the biphasic dose-response: insights into hormesis and retinal neuroprotection
This study found that a natural compound called Brosimine B helps protect eye cells from damage caused by lack of oxygen and sugar, but only at a very specific, low dose—too much of it hurts the cells instead.
