A comprehensive review of phytochemical components as potential antidepressants

Abstract

Depression is a heterogeneous mood disorder that has been classified and treated in a variety of ways. Despite the fact that a variety of synthetic medications are utilized as conventional treatment for clinically depressed patients, these drugs have side effects that can jeopardize the therapeutic outcome. In recent decades, there has been a rise in research and interest in the psychopharmacology of natural treatments. Thus, it’s worthwhile researching for antidepressants derived from plants that have a demonstrated effect and a favorable benefit-to-risk ratio. By virtue of their medicinal constituents, a variety of medicinal plants and medicines produced from these plants have exhibited antidepressant properties. As a result, major pharmaceutical companies are currently researching plant materials extensively for their possible medical benefit. Depression is caused by low levels of monoamines such as noradrenaline, dopamine, and serotonin in the brain. Therefore, treatments that restore lowered levels of these monoamines in the brain by blocking monoamine oxidase or decreasing reuptake of these neurotransmitters could be beneficial in the treatment of depression. The current review focuses on medicinal plants and plant-based formulations that have been shown to have antidepressant effect in both animal and human studies.
