Eir. Goddess of healing in Norse Mythology. As a Valkyrie Eir accompanied her battle-sisters. While the other Valkyries chose the slain Eir would choose who would live and recover and return to health.
Folk tradition holds that Eir was invoked in healing rituals using a white flower known as Eirflower. She is associated with copper which was used in healing ceremonies.
Fun fact: before the rise of the male dominated medical institutions of Europe the healing and medical care of the community in Norse and Germanic countries was largely the sphere of women. Although the Sagas record several male healers during the pagan period the role of doctor was women’s work while men were usually nurses or helpers. If you wish to call upon Eir you should light a red or green candle as It was common to do so while praying for healing.
