Migraine is a common neurological disorder characterised by recurrent episodes of headache accompanied by a constellation of sensory, autonomic, and cognitive symptoms. Despite significant advances in conventional therapeutics, many patients continue to experience inadequate relief, medication-related adverse effects, and reduced quality of life. Consequently, complementary and integrative approaches have gained increasing attention. Among these, homoeopathy offers a distinctive therapeutic framework based on the principle of individualisation. Unlike disease-centred treatment models, homoeopathic prescribing focuses on the unique symptom expression, constitutional characteristics, and psychosomatic profile of each patient. The present review critically examines the role of homoeopathic individualisation in the management of functional migraine. Classical foundations derived from Hahnemannian philosophy are explored alongside contemporary developments in repertorisation, constitutional prescribing, evidence-informed practice, and personalised healthcare. The review further evaluates available clinical evidence, discusses methodological challenges, and identifies opportunities for future research. The analysis suggests that individualisation remains central to homoeopathic management of migraine and aligns conceptually with modern precision medicine approaches. However, robust scientific investigations are required to strengthen the evidence base and establish clearer clinical recommendations.
