Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Peppermint (Mentha × piperita) has a long history of use in traditional medicine for alleviating symptoms of respiratory congestion. The primary active constituent, menthol, is known for its cooling sensation and is commonly included in over-the-counter products such as chest rubs and inhalants. Scientific studies have demonstrated that menthol can activate cold-sensitive receptors in the nose and throat, which can create a subjective feeling of improved nasal airflow, even if objective measures of airflow do not significantly change. Some research suggests that inhaling menthol vapors may transiently improve the sensation of breathing in people with nasal congestion, but clinical trials have generally not shown a significant effect on actual decongestion or mucus clearance compared with placebo.

A few small studies and reviews (e.g., Eccles R, 1994; American Journal of Rhinology, 2008) indicate that while menthol provides a sensation of easier breathing and may offer mild symptomatic relief, it does not physiologically open nasal airways or treat the underlying cause of congestion. Peppermint oil, when used in aromatherapy or topical applications, is considered safe for adults but may be hazardous for infants and young children due to the risk of respiratory distress.

In summary, the use of peppermint for congestion is supported by both tradition and a modest degree of scientific evidence, though its efficacy is limited to symptom relief rather than true decongestion. The evidence rating is 2 out of 5, reflecting subjective benefits more than objective efficacy.
