A recent paper by Sriranjini et al., based on a rotenone model of drosophila, reports [1]:
"rotenone-mediated neurotoxicity may be largely related to the combined antioxidant activity of bio-actives resulting in improved locomotor performance, abrogation of oxidative stress and mitochondrial dysfunction. Based on these results, we propose that cumin and cinnamon extracts may be exploited as therapeutics against PD and other neurodegenerative diseases."
