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 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.
