Improves Memory and Concentration

Rosemary produced a significant enhancement of performance for overall quality of memory and secondary memory factors, but also produced an impairment of speed of memory in healthy adults. Rosemary could also improve mood and alertness. Another study published in the Journal of Medicinal Food investigating the effects of dried rosemary leaf powder on cognitive performance in older adults found that a 750mg-dose of rosemary had a statistically significant beneficial effect on memory, whereas the 6000mg-dose had a significant impairing effect on cognitive function.
