Can Peppermint Tea Make You Smarter?

Want to be smarter? What if a simple cup of herbal tea could do the trick? Turns out, maybe it can!

An intriguing recent finding is that many plants in the mint family are great for enhancing cognition. Proven mints include rosemary, sage, lemon balm, and peppermint.

Several studies have shown that inhaling peppermint aroma or consuming peppermint improves cognition, memory and attention.

This new single-blind study set out to see if a single 200mL cup of peppermint tea was strong enough to do the trick. It was!

Compared to a placebo tea, peppermint tea significantly improved the composite cognitive score as well as all individual scores measured. It was especially good at improving memory and attention.

This study adds to the growing body of evidence that mints, including peppermint, boost cognition. This study adds the promising piece that a single cup of peppermint tea can do the trick, especially for memory and attention.
