Synopsis

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

Mint, particularly varieties such as peppermint (Mentha piperita) and spearmint (Mentha spicata), has been traditionally used to support sinus health and relieve symptoms associated with sinus congestion. Historical records from various cultures indicate that mint leaves and their essential oils were used for their aromatic properties to open nasal passages and provide a sensation of easier breathing. The primary compound responsible for these effects is menthol, which provides a cooling sensation and can create a subjective feeling of improved airflow in the nasal passages.

While there is some scientific evidence supporting the use of menthol for subjective relief of nasal congestion—such as menthol in vapor rubs providing a cooling sensation—clinical studies have shown that menthol does not actually decongest or increase nasal airflow. Instead, it makes users feel as if their airways are clearer. Therefore, while mint's use for sinuses is rooted primarily in tradition, with some support from modern research for its symptomatic effects, the direct physiological benefit is limited. The evidence level is moderate due to the long history of use and limited but suggestive scientific studies on menthol's sensory effects, but it does not reach higher levels due to lack of robust clinical outcomes demonstrating true decongestion.
