Hyland's "migraine headache
relief" is a combination of multiple homeopathic remedies, any of which might be called for in an individual who suffers migraines.
If your headache symptoms correspond to any of these remedies, the formulation could help. (if not, it won't.) a trained homeopath could help you in a much more individual way. http://www.hylands.com/products/migraine.php/.
