These Runes were used in the Middle Ages and are mostly Germanic and Dutch in origin.
Such runes were used for protection and healing, but not rune-casting. In fact they were mainly associated with Gods and Goddesses that were worshiped secretly in Christian times.
Each rune has a symbol on it that has its own magickal as well as healing meaning.
Many use these runes on their altars as they do represent Gods and Goddesses that are still worshipped today.
For Healing, people have used these runes to wear as pendants, or in their magical workings for healing spells.
