Analysis of the results showed that peppermint tea significantly improved long term memory, working memory and alertness compared to both chamomile and hot water. Chamomile tea significantly slowed memory and attention speed compared to both peppermint and hot water.
Dr Mark Moss said: “It’s interesting to see the contrasting effects on mood and cognition of the two different herbal teas. 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.”
