Rating (out of 5): 1

Spearmint leaf (Mentha spicata) has a long history of use in traditional herbal medicine for relieving symptoms of colds, including congestion. In various cultures, spearmint tea or inhalation of its vapor has been recommended to ease breathing and soothe irritated respiratory passages. The traditional rationale is based on its aromatic and mildly soothing properties, which may provide temporary relief from nasal stuffiness and mild throat discomfort. While spearmint contains essential oils such as carvone and limonene, which have mild antimicrobial and anti-inflammatory effects in laboratory settings, there is little direct scientific research specifically supporting the use of spearmint as a potent decongestant in humans. Most clinical studies focus on other mints, particularly peppermint, which contains higher levels of menthol—a compound known for its decongestant effect. Spearmint’s lower menthol content means it is less likely to produce a strong sensation of airway opening. Overall, the use of spearmint for cold-related congestion is primarily rooted in traditional herbal practices rather than robust scientific validation. Its pleasant flavor and aroma may provide subjective comfort, but evidence for significant decongestant activity is limited.
