Researchers from Northumbria University, in England, have discovered that drinking peppermint tea can improve working and long-term memory. After 180 healthy adults filled out questionnaires about their mood, they were selected at random to consume one of three drinks—peppermint tea, chamomile tea or water—and then rested for 20 minutes.
The subjects were then tested for memory and other cognitive factors and given a second mood questionnaire. Those that drank peppermint tea exhibited improvements in both types of memory and were more alert than the other two groups. The participants that drank chamomile tea displayed slower memory function and decreased attention speed compared to the others.
Researcher Mark Moss, Ph.D., notes, “The enhancing and arousing effects of peppermint and the calming, sedative effects of chamomile observed in this study are in keeping with the claimed properties of these herbs and suggest beneficial effects can be drawn from their use.”
