Bridging Herbal, Synthetic, and Non-Pharmacological Approaches for Stress: Diagnostics and Therapeutic Impact

Stress is a pervasive global health concern with far-reaching psychological, neuroendocrine, and physiological consequences. The World Health Organization (WHO) estimates that more than one billion people worldwide suffer from mental health disorders, including stress-related conditions such as anxiety and depression. This review comprehensively explores the classification, clinical manifestations, and intricate pathophysiology of stress, including dysregulation of the hypothalamic–pituitary–adrenal (HPA) axis and neurotransmitter alterations. Diagnostic approaches encompassing psychological assessment tools (Perceived Stress Scale, Stress Appraisal Measure), biochemical and hormonal indicators (cortisol, emotional biomarkers), and neurophysiological techniques (EEG) are discussed. Both pharmacological and non-pharmacological interventions are reviewed, including herbal medicines (Ashwagandha, Rhodiola, Tulsi, Brahmi, Ginseng), synthetic drugs (SSRIs, SNRIs, benzodiazepines, beta-blockers), and evidence-based therapies (CBT, MBSR, ACT). A comparative analysis of herbal versus synthetic approaches is presented, highlighting the benefits and limitations of each. The review concludes that an integrated, personalized approach combining herbal, synthetic, and non-pharmacological strategies offers the most promising direction for comprehensive stress management.
