The video promotes rosemary tea as a way to restore memory, but the evidence only suggests limited, short-term effects in small studies—not that it can reboot the brain or reverse memory loss.
Claim-by-claim breakdown
False (89% confidence): Drinking rosemary tea or water can bring back memory in older adults or people with memory loss. NCCIH says direct evidence that dietary supplements prevent or treat cognitive decline or dementia is lacking. The best human rosemary study found only a brief, dose-dependent effect on one memory measure, with higher doses impairing…
Unsupported (74% confidence): Rosemary tea can reboot the brain for students or improve school-related memory and learning. Available human studies are small and short-term, and the NCCIH notes that direct evidence for cognitive benefits from supplements is lacking. That does not establish a student learning benefit.
Misleading (81% confidence): A rosemary drink can be used like coffee to improve brain function throughout the day. A PubMed study of rosemary water reported small, short-term beneficial effects in healthy adults, but that is far from proof of a robust or lasting brain-boosting effect.
