10 Benefits of Peppermint Tea
Benefit #6: May Relieve Clogged Sinuses
Another great benefit of drinking peppermint tea is its effect on fighting sinus infections, allergies, and colds. This effect is possible because the tea has antibacterial and antiviral properties, which boost the immune system and help fight off pathogens. In addition, menthol, an active compound in peppermint, can improve airflow in your nasal cavity.
In one study 40 participants inhaled menthol. Upon inhalation of the menthol, a significant enhancement of nasal sensations of airflow was reported. Thus, if you have a sinus problem, drinking peppermint tea or even inhaling it while it is hot can be very helpful in increasing air flow.
