Synopsis

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

Peppermint (Mentha × piperita) has a long history of traditional use for soothing sore throat symptoms. In folk medicine, peppermint tea, lozenges, or inhaled vapors have been used to ease throat discomfort due to its cooling sensation and pleasant flavor. The key active component, menthol, provides a cooling effect by activating cold-sensitive receptors in the throat, which can temporarily relieve the feeling of soreness or irritation.

While these traditional uses are well documented, scientific validation is limited. There are very few high-quality clinical studies directly assessing peppermint or menthol for sore throat relief. Some laboratory research and small clinical trials suggest that menthol may have mild analgesic (pain-relieving) and anti-inflammatory properties, but these findings are often extrapolated from studies on cough, cold, or upper respiratory tract symptoms rather than sore throat specifically. Major medical guidelines do not formally recommend peppermint as a primary treatment for sore throat, though it may be included in over-the-counter remedies for symptomatic relief.

In summary, peppermint’s use for sore throat is primarily grounded in traditional practice and anecdotal experience, with modest scientific plausibility chiefly due to menthol’s sensory effects. Evidence supporting its effectiveness is weak to moderate (rated 2/5), and it should not replace established medical treatments for more serious underlying conditions.
