title: Ergot of rye-the first specific for migraine.
abstract: Over the past decade the various triptan derivatives have been accepted as the most effective available agents for relieving migraine attacks. Prior to that, for a period of half a century, ergotamine was the only 'specific' available for this purpose. In 1918, Stoll had isolated it from the various alkaloids present in extracts of the sclerotia of the fungus Claviceps purpurea (ergot), which grow on rye and, to a lesser extent, on other grasses. By 1925 ergotamine was beginning to be used to treat migraine attacks. However, as ergotamine was present in extracts of ergot, which had been used to treat migraine first in Italy in 1862, and then by Edward Woakes (1868) in England, and after him by Albert Eulenburg in Germany (1883), the drug had actually come into unrecognised use for the disorder more than half a century before ergotamine itself was known to exist. Unfortunately, because of ergotamine's chemical and pharmacokinetic properties, extracts of ergot of rye were incapable of producing consistent therapeutic results, so that general acceptance that the first specific substance for migraine treatment existed had to wait until pure ergotamine was available for administration.
