But even before Christianity was brought to Ireland, the shamrock played an important role on the Emerald Isle. For example, grinded clover that was rubbed on the eyes was supposed to make visible a fairy island that is supposedly located between Rathlin Island and the north coast of Ireland. To cleanse the blood, clover was often brewed and drunk as tea. Also in Ireland the four-leaf clover is said to bring luck, because it is said to attract fairies. The Irish only have the three-leaf clover as a national symbol thanks to the holy St. Patrick. This is exactly why it keeps popping up.
