ABSTRACT Headaches have afflicted man throughout history, and Migraine is a common, but under diagnosed and under treated type of headache that has a strong social impact, influencing both quality of life and work productivity. Stress, food allergies, neuro endocrine imbalances and nutritional deficiencies all may contribute to migraine attacks. Several mechanisms have been implicated in migraine patho physiology including inflammation, mitochondrial dysfunction, abnormal neuronal excitability and vascular events. Drugs from different pharmacological classes are used for migraine prophylaxis and these agents may normalize neuronal excitability by modulating distinct ionic channels and various neurotransmitter systems. They can also block cortical spreading depression; prevent peripheral and/or central pain sensitization. Over the last two decades, the results from clinical studies have provided evidence of efficacy of allopathic and herbal drugs which have shown a considerable relief in complications of migraine yet a lot of pathological mechanisms and resultant sufferings remain unresolved.

INTRODUCTION There are many types of headaches, each with its own set of causes, symptoms and points of pain. The more common types include tension, cluster, migraine, allergy/sensitivity, sinus, trauma, and eyestrain headaches 1.The term migraine is originated from Greek word “hemicrania”2 meaning “one side of the head’’. Migraine is the most common of the disabling primary headache syndromes3 that affect around 12% of the general population4. It has a strong social impact, influencing both quality of life and work productivity5 and is ranked as the 19th leading cause of disability worldwide6,7. Migraine, a common chronic, incapacitating neurovascular and neurological disorder is characterized by autonomic nervous system dysfunction and intense, unilateral, throbbing, pulsatile headache attacks, lasting for 4-72 _________________________________ *Corresponding author: Vivek Sharma Department of Pharmacology, Govt.

hours, accompanied by anorexia, nausea, vomiting, photophobia, phonophobia7 and osmophobia8,9. These symptoms distinguish migraine from tension-type and other rare forms of primary headache, which lack these associated features. Because of its high prevalence among population and considerable burden on the society, the therapy of migraine is an issue of high importance. Although homeopathy did not show any efficacy in migraine prophylaxis in controlled trials10,11 the drugs from allopathic and ayurvedic system are successfully used in treatment as well as minimizing symptoms of migraine. Migraine is currently considered a complex interplay of different processes such as an alteration of pain and sensory input, increased sensitivity of the cortex leading to aura phenomena, central pain facilitation,
