Airmed –  also Airmid, Airmeith and Airmedh, she is the daughter of the healing god Dian Cecht and sister of Miach. Irish goddess associated with herbal healing. In one version of the story of the healing of the king Nuada by Miach, after Miach died Airmed found healing herbs growing from his grave and harvested them; she laid all the herbs out on her cloak and organized them to preserve the knowledge of their properties. Some sources say the herbs numbered 365, with one for each of his sinews and joints, and one for every possible bodily ailment. Many people today associate her especially with herbal healing. I have often used a mortar and pestle to represent her on my altar; she is also associated with the cloak or mantle, called a brat in Irish.
