Peppermint leaf (Mentha × piperita) has a long history of traditional use for relieving symptoms of congestion, particularly in folk medicine and herbal traditions. The main active component, menthol, is known for producing a cooling sensation and is believed to help open nasal passages and ease breathing. Traditional use often involves drinking peppermint tea or inhaling steam infused with peppermint leaves to relieve congestion from colds or respiratory infections.

While menthol is a prominent ingredient in many over-the-counter decongestant rubs and inhalers, the scientific evidence supporting the use of peppermint leaf itself for treating congestion is limited. Some studies suggest that menthol can improve the subjective feeling of nasal airflow, although it does not actually decrease nasal airway resistance or clear mucus. Most clinical research has focused on menthol rather than the whole peppermint leaf, and results indicate that relief is largely due to the cooling sensation rather than true decongestant effects.

In summary, the use of peppermint leaf for congestion is primarily based on traditional practices, with modest support from the physiological effects of menthol. However, robust scientific validation for peppermint leaf as an effective treatment for congestion is lacking.
