Rating (out of 5): 3
Menthol is a naturally occurring compound found in mint plants, widely known for its cooling sensation and distinctive aroma. Its use in supporting the "Smell" body system—more specifically, olfactory function—has some scientific basis, though the evidence is moderate rather than robust. Menthol's distinctive scent is often used in olfactory training, a therapeutic approach for individuals experiencing loss or alteration of their sense of smell (anosmia or hyposmia), such as after viral infections (including COVID-19). In olfactory training, patients repeatedly sniff specific odors (often including menthol, rose, lemon, and clove) to stimulate and potentially rehabilitate the olfactory nerve pathways.
Several peer-reviewed studies have demonstrated that olfactory training can lead to partial or, in some cases, significant improvement in olfactory function. Menthol is selected for such protocols due to its strong, easily recognizable aroma, which helps engage and challenge the olfactory system. However, it is important to note that menthol is not directly repairing nerves but is used as a tool within a broader therapeutic context. There is less evidence for menthol alone being effective outside of such structured programs. Overall, while menthol's role in supporting the sense of smell is not based on traditional use, there is moderate scientific support for its inclusion in evidence-based olfactory training protocols.
