Spearmint leaf (Mentha spicata) has a long history of use in traditional herbal medicine to address mild respiratory issues, including congestion. In folk remedies, spearmint teas and inhalations have been used to help soothe the throat and open airways, likely due to the presence of aromatic compounds such as carvone and limonene. However, compared to its relative peppermint, which contains significant amounts of menthol (a compound known for its decongestant effects), spearmint contains far less menthol and does not produce the same cooling or decongestant sensation.

The traditional use of spearmint for congestion is primarily anecdotal, passed down through generations and featured in various ethnobotanical records. While the plant's pleasant aroma and mild flavor have made it popular in teas and home remedies for cold symptoms, there is little modern scientific evidence directly supporting its efficacy for treating nasal or chest congestion. Most clinical studies on mint species focus on peppermint or menthol-rich preparations, not spearmint.

In summary, spearmint's use for congestion is based on tradition rather than scientific validation. The evidence supporting its effectiveness is weak, mostly relying on historical usage and the general soothing qualities of warm herbal teas, rather than any proven pharmacological action against congestion.
