Mint (Mentha species), particularly in the form of menthol, has a long tradition of use for relieving symptoms related to sinus infections and other upper respiratory conditions. Traditionally, mint leaves and menthol extracts have been included in steam inhalations, balms, and teas, with the intent to ease breathing, clear nasal passages, and soothe irritation. This use is rooted in the aromatic properties of mint, which can produce a cooling sensation and provide subjective relief from congestion.

From a scientific perspective, the evidence supporting mint's efficacy in treating sinus infections is limited. Menthol, the main active component in mint, does not actually decongest nasal passages but can create a feeling of improved airflow by stimulating cold receptors in the nose. Some small studies and reviews (e.g., Eccles et al., 1994) have demonstrated that menthol can subjectively improve the sensation of nasal airflow, but objective measures do not confirm actual decongestion. There is insufficient clinical evidence to suggest that mint or menthol can treat the underlying infection or significantly reduce inflammation associated with sinusitis.

In summary, while the use of mint for sinus infection symptoms is primarily traditional and may provide subjective relief, scientific validation is weak and does not support its use as a primary treatment for sinus infection.
