Eucalyptol and menthol formulations
Menthol and eucalyptol provide a sensation of cooling and freshness 1
Menthol provides a cooling effect by stimulating temperature receptors in the nose, leading to the perception of decongestion and improved nasal breathing. 1,2
Nasal sprays containing eucalyptol and menthol are available in combination with other ingredients such as xylometazoline or natural saline.
When in combination with xylometazoline, such nasal sprays should be administered 2-3 times daily, 1 spray per nostril at a time, and should not be used more often than every 8 hours.4
When in combination with seawater, such nasal sprays may be administered up to 6 times daily per nostril.7
Eucalyptol and menthol provide a sensation of cooling and freshness,2
Eucalyptus extract provides a cooling sensation in the nose and an immediate perception of increased airflow2
According to Burrow’s study (1983)14, after exposure to menthol & eucalyptus, the majority of subjects reported a cool sensation on nasal aspiration. This sensation was reported by all subjects after exposure to menthol and was generally reported to be a pleasant sensation of cool airflow. An increased sensation of nasal airflow was reported after exposure to eucalyptus and menthol.3 3
Menthol extract stimulates cold-temperature receptors on mucosal surfaces of the nasal passageways
Menthol provides a cooling effect by stimulating cold-temperature receptors on mucosal surfaces of the nasal passageway,4 providing the perception of relief from congestion.1
The effect provided by eucalyptol and menthol application is asserted to be as a result of the perception of improved airflow, rather than actual improved airflow1
Multiple studies have established that both inhalation and oral ingestion of eucalyptus and menthol provide a cold sensation through the nose with the sensation of improved airflow,4 but with no measurable effect on nasal resistance as measured by posterior rhinomanometry.5,6
