Study finds three plants may boost memory and cognition in seniors

A study published in the journal Nutrients has found that three medicinal plants—bacopa (Bacopa monnieri), ginseng (Panax ginseng), and saffron (Crocus sativus)—may help improve memory and cognitive function in older adults experiencing age-related cognitive decline.

The researchers explained that these plants have a positive effect on brain function, with their use linked to better performance in general cognitive assessment tests.

The study team noted that compounds found in these plants may reduce oxidative stress and inflammation, support mitochondrial function, and influence processes related to the accumulation of beta-amyloid protein and pathological changes in tau protein, both of which are key factors in the development of Alzheimer’s disease.

The researchers added that certain plant compounds may enhance neuroplasticity—the brain’s ability to modify connections between neurons and form new ones—which is essential for learning and memory.

However, the study authors emphasized that current evidence remains insufficient, and medicinal plants should not be considered a substitute for approved treatments for cognitive disorders.
