Mint (Mentha species), particularly peppermint (Mentha piperita), has a long history of traditional use for supporting the health of mucus membranes, especially in the respiratory and digestive tracts. In various folk medicine systems, mint leaves and their essential oils have been used as remedies for soothing sore throats, easing coughs, and alleviating symptoms associated with colds and congestion. These uses are largely based on the plant’s cooling sensation and aromatic properties, which can provide subjective relief of irritation and discomfort in the mouth, throat, and nasal passages.

The primary active constituent, menthol, is known to have mild local anesthetic and decongestant effects, which can temporarily soothe irritation of mucus membranes and provide a sensation of improved airflow. However, while these properties are well established for symptomatic relief, there is limited direct scientific evidence showing that mint or menthol physically supports the health or repair of mucus membranes themselves. Most clinical studies focus on symptom management (e.g., cough suppression, throat soothing) rather than on underlying mucosal healing.

Therefore, the use of mint for mucus membrane support is primarily justified by tradition and symptomatic relief, rather than robust scientific validation of direct benefits to the structure or function of mucus membranes.
