Anti‐Inflammatory Effects of Plant Metabolites on Neurological Health

Abstract

The exploration of anti-inflammatory effects of plant metabolites on neurological health has gained significant attention due to the rising prevalence of neurodegenerative diseases (NDDs). This abstract summarizes key findings regarding the role of secondary metabolites derived from plants in modulating neuroinflammation, a critical factor in the pathogenesis of conditions, such as Alzheimer's and Parkinson's diseases. Recent studies have demonstrated that various bioactive compounds, including flavonoids, polyphenols, terpenoids, and alkaloids, exhibit potent anti-inflammatory properties. These metabolites have been shown to reduce oxidative stress and inhibit proinflammatory cytokines, thereby protecting neuronal cells from damage. For instance, extracts from plants like Curcuma longa (turmeric) and Zingiber officinalis (ginger) have been highlighted for their efficacy in mitigating inflammation through mechanisms, such as the inhibition of cyclooxygenase enzymes and modulation of nuclear factor kappa-light-chain enhancer of activated B cells (NF-κB) pathways. Moreover, clinical trials and animal models indicate that these plant-derived compounds not only alleviate symptoms associated with NDDs but also enhance cognitive function and promote neuroprotection. The interaction between these metabolites and inflammatory pathways suggests a promising avenue for developing novel therapeutic strategies aimed at reducing neuroinflammation and improving neurological health.
