Allergies

Mint contains high levels of rosmarinic acid, an antioxidant that quenches free radicals and reduces allergy symptoms by inhibiting COX-1 and COX-2 enzymes. A study published in the 2004 issue of the journal Biofactors found that 50 milligrams of rosmarinic acid per day for 21 days reduced levels of allergy-related white blood cells, called eosinophils, and inflammatory molecules and decreased allergy symptoms significantly.
