British researchers report that the herb’s crisp scent boosts the brain’s production of energizing beta waves enough to increase energy levels by 50% in just two minutes. And all you have to do, they say, is take a deep sniff of peppermint essential oil, sip a cup of peppermint tea or enjoy a peppermint candy or stick of gum. For an anytime boost, tote a bottle of peppermint oil in your bag!
