May Relieve Clogged Sinuses
Peppermint possesses antibacterial, antiviral, and analgesic effects. As a result, peppermint tea may help to clear congested sinuses caused by infections, the common cold, and allergies. Furthermore, studies show that menthol, one of the active chemicals in peppermint, increases the sense of airflow in the nasal cavity. As a result, the steam from peppermint tea may make you feel as if your breathing is easier.
Warm drinks, such as chicken broth and tea, have also been reported to temporarily alleviate nasal congestion symptoms, most likely because of their vapors. Though the benefits of peppermint tea on nasal congestion have not been explored, evidence suggests that it may be beneficial.
