Menthol in peppermint makes the tea taste minty and mildly sweet, leaving a cooling sensation in the mouth. It's light and refreshing.
Peppermint is caffeine-free and used to soothe an upset stomach or to aid digestion. Peppermint tea has a calming and numbing effect, and is often used to treat headaches, skin irritation, nausea, diarrhea, menstrual cramps, flatulence, and anxiety associated with depression.
