Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Menthol has a long history of traditional use in the management of respiratory discomforts, including symptoms associated with allergies such as nasal congestion and cough. It is commonly found in over-the-counter inhalants, rubs, and lozenges. The sensation of menthol can create a subjective feeling of improved airflow in the nasal passages, likely due to its activation of cold-sensitive TRPM8 receptors, producing a cooling sensation. However, while menthol is widely used traditionally for various respiratory complaints, there is minimal direct scientific evidence supporting its efficacy in treating or improving allergic respiratory conditions specifically. Some small studies suggest that menthol might provide symptomatic relief by making breathing feel easier, but objective measures of airflow or improvement in allergic inflammation are lacking. Thus, its use for respiratory allergies is primarily based on tradition and subjective relief rather than robust scientific validation. Care should also be taken, as menthol can cause irritation or adverse reactions in some individuals, particularly young children. Overall, while menthol is a well-established traditional remedy for respiratory symptoms, its role in managing respiratory allergies is not strongly supported by modern clinical evidence.
