In 
Norse mythology Eir ("help" or "mercy") is a goddess of the 
Ęsir; she knew the medicinal properties of 
herbs and was capable of 
resurrection.  Only women could learn the art of healing in 
Scandinavia, at this time.  She was good friends with 
Frigg.
Her name means "help" and she is skillful in medicine.
She is only briefly mentioned in Snorri Sturluson's Edda and in some kennings.
