Saffranal is a major volatile compound found in saffron (Crocus sativus) and is believed to contribute to its distinctive aroma. In recent years, saffron and its constituents—especially crocin and safranal—have gained attention for their potential antidepressant properties. Several preclinical studies (in vitro and animal models) have suggested that safranal may exert antidepressant-like effects, possibly through modulation of neurotransmitter systems such as serotonin, dopamine, and norepinephrine. For example, rodent studies have shown that safranal can reduce immobility time in the forced swim test, a common assay for antidepressant activity.

Some clinical trials have investigated saffron extract (which contains safranal among other compounds) for depression, and meta-analyses suggest that saffron supplementation may improve symptoms of mild to moderate depression compared to placebo and may be as effective as certain standard antidepressants. However, it is important to note that most clinical research has used whole saffron extracts, not isolated safranal, so the specific contribution of safranal remains less well defined.

Overall, while the use of safranal for depression is supported by preclinical data and saffron extract has some clinical evidence, direct clinical evidence for safranal alone is limited. Thus, the evidence rating is moderate (3/5), reflecting promising but not definitive support for safranal’s use in depression management.
