**6. Conclusion**

EOs are natural products with diverse biological importance in different fields due to the inherent chemical constituents or components. The crux of this chapter is the antioxidant properties of EOs immensely contribute to the prevention, treatment and management of NDs. The multiple mechanisms of action of EOs antioxidants match or counter the multifactorial processes such as oxidative stress, neuroinflammation, excitotoxicity and others involved in NDs pathology. Although attaining the most effective therapeutics is essential, the CNS's molecule or drug delivery barrier is a significant concern in treating and managing NDs. Many approaches using modern technology supported by research evidence, no doubt, have tremendously contributed to finding near or total solutions to incurable NDS. Therefore, effort must be channeled towards discovering and developing novel EOs and drug delivery systems through innovative and holistic research and collaboration towards finding lasting solutions to NDs.
