Study Shows Spearmint, Rosemary Aid Memory in Mice

Study Shows Herbs Aid Memory in MiceResearch on an animal model has resulted in promising findings as enhanced extracts made from special antioxidants in spearmint and rosemary were found to improve learning and memory.

Researchers from Saint Louis University discovered compounds made from the herbs reduced deficits caused by mild cognitive impairment, which can be a precursor to Alzheimer’s.

“We found that these proprietary compounds reduce deficits caused by mild cognitive impairment, which can be a precursor to Alzheimer’s disease,” said Susan Farr, Ph.D., research professor in geriatrics at Saint Louis University School of Medicine.

Said Farr: “This probably means eating spearmint and rosemary is good for you.

“However, our experiments were in an animal model and I don’t know how much — or if any amount — of these herbs people would have to consume for learning and memory to improve.

“In other words, I’m not suggesting that people chew more gum at this point.”

Farr explained that she tested a novel antioxidant-based ingredient made from spearmint extract and two different doses of a similar antioxidant made from rosemary extract on mice that had age-related cognitive decline.

She found that the higher dose rosemary extract compound was the most powerful in improving memory and learning in three tested behaviors.

The lower dose rosemary extract improved memory in two of the behavioral tests, as did the compound made from spearmint extract.

Further, there were signs of reduced oxidative stress, which is considered a hallmark of age-related decline, in the part of the brain that controls learning and memory.

“Our research suggests these extracts made from herbs might have beneficial effects on altering the course of age-associated cognitive decline,” Farr said. “It’s worth additional study.”
