Eolhx is the sounds of “x” or “z”

Anglo-Saxon Rune Poem (from ragweedforge.com)

The Eolhx-sedge is mostly to be found in a marsh;
it grows in the water and makes a ghastly wound,covering with blood every warrior who touches it
Eolhx, the rune of protection, is the rune for this first Wednesday in August. It symbolizes protection, security, and sanctuary. Within the confines of an area marked by eolhx, one may find rest, peace, and quietness which allows one to cast off burdens momentarily, so that healing and regeneration, both physical and spiritual can occur
