Parkinson's disease (PD) is the second most common neurodegenerative disorder in the elderly, currently with no cure. Its mechanisms are not well understood, however α-synuclein protein aggregation plays a central role in the pathogenesis of PD, leading to neurodegeneration. We demonstrated that in a PD model dietary in Caenorhabditis elegans treatment with an extract from the rhizome of Canna coccinea decreased the accumulation of α-synuclein. The extract showed low toxicity to neuro 2a cells and protected them from oxidative damage with H
