The available studies linked to peppermint for sinus and congestion relief do not actually investigate peppermint or its active compounds in this context. The two studies provided are observational and epidemiological in nature, focusing respectively on persistent smell and taste dysfunction following COVID-19 infection and on COVID-19 vaccine effectiveness against the Omicron variant in a congregate setting. Neither study examines peppermint as an intervention for nasal congestion or sinus symptoms, and therefore no conclusions about peppermint's effectiveness for this use can be drawn from the evidence as presented. Readers interested in the research on peppermint for sinus and congestion relief would need to consult studies that directly investigate menthol or peppermint preparations in relevant clinical or physiological contexts.
