Review of Phytochemical Potency as a Natural Anti- and Neuroprotective Agent.

Phytochemicals are plant secondary metabolites that show health benefits for humans due to their bioactivity. There is a huge variety of phytochemicals that have already been identified, and these compounds can act as antimicrobial and neuroprotection agents. Due to their anti-microbial activity and neuroprotection, several phytochemicals might have the potency to be used as natural therapeutic agents, especially for infection and neurodegenerative disease, which have become a global health concern nowadays. According to previous research, there are some connections between infection and neurodegenerative diseases, especially Alzheimer's disease. Hence, this comprehensive review examines different kinds of phytochemicals from natural sources as potential therapeutic agents to reduce infection and improve neurodegenerative disease. An additional large-scale study is needed to establish the connection between infection and neurodegenerative disease and how phytochemicals could improve this condition.
