Neurological disorders and their sequelae, as of the widespread and critical humans complications, affect the
body's nervous systems, organ functions, and behaviors. According to WHO, neurological disorders are currently predicted
to affect more than one billion people globally. It is well-established that complementary medicine is one of the high accepted interventions that could have been considered for the management of neurological ailments. The current review aimed to
compile a frame from all the crucial data reporting the investigation on the conspicuous intervention of green tea (made of
Camellia sinensis) and related lead compounds (especially l-theanine, epigallocatechin-3-gallate, epicatechin-3-gallate, epicatechin, and epigallocatechin) for their neurological activities, mechanisms of action, and clinical properties. According to
the documents, green tea exhibits antidepressant, anti-neurodegenerative (e.g., anti-Parkinson and anti-Alzheimer), as well
as neuroprotective effects. Chief among them, for offering novel work, it is worth focusing on several related assessments
with great attention to more extensive standardized clinical trials, and subsequently more in-depth pharmacokinetic studies
to safely introduce this beneficial medicinal food as a neuro-effective agent.
