2017). Saffron and its active ingredients have been known to treat anxiety, depression and other mental disorders due to their effect in modulating neurotransmitter releases, which are a less toxic and more favorable outcome (Shafiee et al. 2018).

This evidence concerns the gene TH and mental disorder.
