Saffron (Crocus sativus) improved erectile function scores in a 2009 trial and reversed SSRI-induced sexual dysfunction in men in a 2012 randomized study. It also has multiple trials on mood comparable to low-dose antidepressants.
Crocin and safranal modulate serotonin and have antioxidant activity. Saffron is the mood-and-drive component of Maxorin.
