The Brat Bríghdhe - A white cloth is got and hung out overnight. This will cure headaches and is efficacious as effective for a year. Can be repeated at subsequent anniversary. Prayers are supposed to be said to St Brigid. *(druid version given at end of book)
This is not uncommon still, I am a personal witness to the hanging out of the Brat Bríghdhe by a neighbour in 1936.
