Published November 14, 2013 | Researchers from Saint Louis University discovered that compounds made from spearmint and rosemary reduced deficits caused by mild cognitive impairment, which can be a precursor to Alzheimer’s and other aging related cognitive affects.
In new laboratory research involving mice, the scientists found a novel antioxidant-based ingredient made from spearmint and two different doses of a similar antioxidant made from rosemary extract helped improve memory and learning in the animals, and slowed age-related mental declines.
Professor Farr of Saint Luis University presented the early findings at Neuroscience 2013. 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 have 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.

The study lends itself to the assumption that an enhanced extract made from the antioxidants extracted from spearmint and rosemary may also help people in improving their learning and memory.
This is not the very first time that the benefits of rosemary have been highlighted. Along with rosemary, spearmint has antioxidants and is considered good for digestion. Previous research confirm its anti-fungal properties and a treatment to mild hirsutism in women.
The research, which was supported by the VA Medical Center in St. Louis, was conducted in conjunction with Kemin Industries, which manufactures specialty ingredients for vitamin and dietary supplements.
