Menthol oil, obtained from peppermint and other mint oils, is commonly used to support the mucus membranes, particularly those of the respiratory tract. There is scientific evidence supporting its use, primarily due to its cooling, soothing, and mild anesthetic effects when applied to mucosal surfaces. Menthol acts on cold-sensitive receptors in the nasal mucosa (TRPM8 ion channels), providing a subjective sensation of improved airflow and relief from nasal congestion, though it does not physically reduce mucus or congestion. Clinical trials have shown that menthol inhalation can reduce the sensation of dyspnea (difficulty breathing) and improve perceived nasal patency, even if objective airflow measurements do not change (Eccles, 2015). Additionally, menthol's mild local anesthetic properties can help soothe irritations in the throat and upper airways, making it a common ingredient in cough syrups and lozenges. However, while the symptom relief is well-documented, menthol does not address underlying causes of mucus membrane irritation or infection. Overall, the use of menthol oil for symptomatic support of mucus membranes is supported by moderate scientific evidence, mostly for symptomatic relief rather than curative effects.
