Plants for The Mind: The Role of Herbal Medicines in Managing Depression, Anxiety, And Cognitive Decline

Mental health disorders such as depression, anxiety, and cognitive decline are widespread and contribute significantly to global disease burden. Although synthetic drugs like antidepressants and anxiolytics are commonly used, their side effects and limited efficacy have led to growing interest in herbal alternatives. Traditional medicine systems like Ayurveda and Traditional Chinese Medicine offer a range of botanicals with neuroprotective, adaptogenic, and mood-enhancing properties. Herbs such as Ashwagandha, Brahmi, Gotu Kola, Turmeric, and Tulsi contain bioactive compounds that act on multiple pathways—balancing neurotransmitters, reducing oxidative stress, modulating stress hormones, and enhancing brain plasticity. These mechanisms make them promising agents for managing mental health disorders and age-related cognitive decline. This review outlines the pathophysiology of these conditions, highlights key medicinal plants, and examines modern evidence supporting their use, while also addressing safety concerns and future research directions.
